We have a 2019 RAV4 Adventure and I’m wondering if a 255/55R19 tire will fit without rubbing? It comes with stock 235/55R19 toyo tires. I’m looking to get Goodyear DuraTrac’s!
Thank you all in advance!

255/55R19 is a 30.04" tire. I fit a 30.5" tire at roughly stock offsets without rubbing, and I fit a 30.05" tire at a flush offset without rubbing. On stock wheels, I wouldnt expect any issues.

Worst case, if you decide to add wheel spacers or something, you might have to trim about .25 to .5" off the horizontal plastic lip at the forward lower edge of the front wheel wells. I am running my 30.5" tires with a +10 offset up front and that is all I had to do. And I have fully flexed this suspension off road. No rubbing.

On a mildly related note, the 5th gen Rav4 is not a quiet vehicle. Even after adding 75lb of sound deadening material under the entire cargo floor, in all the doors, and under the cabin, I still sold my Duratracs at a $400 loss after about 750 miles due to how loud those tires were.

Hey sorry ressurecting an old post, but I want to do this too and just want to confirm 100%.

I'm looking at putting Geolandar G015 255/55R19 on the stock wheels. You think that should go on without rubbing? The suspension and offset etc will all be stock.

I'm wondering if 255/65-18 size would work on a stock 4.5 Hybrid Limited, using the OEM 18" rims?

The OEM 225/60-18 Dunlops are 28.6" diameter while the 255/65R-18 are 31.1" in diameter. The desire to upsize is driven by wanting to correct the OEM odometer/speedometer error.

Thank you!

I guess I'm going to have to find myself a smart 'tire guy' and investigate just how large I can go without issue(s).

FWIW, Toyota put the same percentage of error into the odometer/speedometer on my '98 Tacoma. It came from the Fremont plant with 225/75R-15s and I've upsized it to 265/75R-16s while having alignments take the (front) caster to the positive limit and just a wee bit beyond. ;)

I am >96% sure you'll be fine. As I recall, with my previous 30" tires at full steering lock I could run my fingers around both edges of the tire. This indicates around .4-.5" of clearance. With the slightly higher offset of the factory wheels, they will be inset another 1/4" from mine, but still shouldn't rub. Worst case, you can get some 3mm or 5mm wheel spacers for pretty cheap on amazon.

The orange line indicates how your tires will sit relative to what I ran.

Hope this helps!

Sorry to keep bugging you but you seem to know what you're talking about haha.

I've crunched the numbers and since the dealer will give me $600 credit for taking off the stocks, it actually works out really close for me to buy 17" rims and tires for 17" rims which gives me way more choice and much cheaper tires.

Since I'm looking at ordering some LP Adventure stuff anyways, they sell some nice looking offroad wheels.


They seem to have 20mm offset and 38 and 40 mm offset.

Since the stocks are 235/55R19 with a 40mm offset would I need a 40mm offset to run larger tires and not rub?

The direct conversion for 17" wheels is 255/65R17, but I could also run 235/70R17 to get bang on to a 30" tire and stock tire width.

So assuming I ran 235/70R17, would it be better to get the 20 offset to move the tire a little further from the sidewall?

It would stick out a good bit more, but I'm not sure if that would cause problems with the fenders or something

The 38mm offset wheels are much closer to stock in terms of closeness but maybe that isn't what I'm looking for ?

One thing you should consider when going to a different wheel and tire size not specified by the manufacturer for your vehicle. What will the insurance company do if you are in an accident and have a tire on your car not specified for your vehicle, I know, but do you? Lawyers on both sides also pay attention to such details.

On a side note, my 2019 RAV4 Limited uses the wheel 235/55R19 too. There is no technical reason going to a wider tire that may not fit the wheel makes any sense to me. I would doubt any distributor would agree to put the wider tire not specified on the door without risking a lawsuit if something happens to anyone in your car that could come back to them. I would not pay attention to any of us backyard mechanics on this forum making such a decision, I would trust the manufacturer of the vehicle, the Explorer fiasco led to manufacturers doing a lot more testing before specifying the right size tire for their product lines.

Good Lord. Please cite a source for this, because I am 99.9% sure none of this is actually true.

You let the store decide what tires you're allowed? What about people with lifts?

I live in northern Canada, damn near every truck and SUV is modded in some way. The insurance company certainly doesnt give a fuck what tire we run as long as it fits.

I appreciate your concern but honestly everything you said is so foreign to anything I've ever even heard of people worrying about that I'm not sure how to reply heh.

In the US, your vehicle has to pass a state safety inspection usually once a year where such things are checked and pass or fail, if they fail, the state comes after your plates. As in Canada, someone can illegally modify between safety periods, which is why I mentioned what will the insurance company do on both sides when you have a modification done to your car. I said I know, I do for PA, NJ, LA, MS, and FL, they will not pay and the parties will have to sue you for damages and if there is a death, enjoy prison for vehicular homicide. I see vehicle in my own state where vehicles are jacked up higher than the wheel well, State Police should be confiscating these vehicles, why they do not is beyond my comprehension. All it will take is for me to get in an accident with one of these people and the State Police will be taking them to jail and confiscating their vehicle or risk losing their badge.

California, which is in the US, does not have an annual inspection. Every two years you have to have a smog check but only after the first 5 years has passed for a new car. This is only a smog check not a vehicle inspection. The only issue for changing tire size would be the speedometer changing how fast you your speedometer thinks you're going.

I would personally tend to lean toward the +20 offset with 235-width tires, knowing there is a slight chance the mud flaps would need to be removed (or ground down a bit?), or that the front lower valence would need to be trimmed a hair.

As to offset affecting fore-and-aft rubbing; imagine how when you turn the steering wheel, the outer edge of the tire actually moves forward and backward by some amount. This is usually called the "turning arc." Lower offset wheels (more "stickout") increase the overall length of the turning arc, so you are actually more likely to rub with lower offsets.

As an extreme example, imagine if you put in wheel and tire that was 120" wide. Basically a long cylinder sticking out of the wheel well. The wheel still pivots on the same axis when you turn the steering wheel, so now the outer edge of the rim is swinging foward and backward like 6 or 8 feet!

That said, as I mentioned above, I would go with the +20, knowing there is a mild chance Id have to remove the front mud flaps (if you have them) or trim the lower front valence (which is super un-intrusive).

If the smaller offset which sticks out more has a large chance of needing trimming, why do you recommend the 20 over the 38?

I am fine doing some minor grinding or trimming just wonder what the reasons are so I can understand better.

Two vehicles ago I drove this (sold about 15 months ago):

I took the ol girl out pretty regularly, like a few times a week. We had a blast.

I have also made my Rav pretty aggressive (for a Rav), with 30.5" tires and 2" F / ~5" rear lift. Still, especially since I dont really play in mud anymore, I appreciate road manners a little more these days. I actually sold my aggressive AT/MT hybrids after several hundred miles because even after adding 75lbs of sound deadening around the vehicle, they were still super loud. My current mild ATs are not too loud, but I still occasionally find myself googling "Quietest All Terrain Tires," haha.

Bottom pine, dont feel bad wanting to keep road manners, especially in this vehicle which is not terribly quiet.

If you go 255-width, 30.1" tire I would stay between 35 and 40 offset.

How did this setup go? I'm getting 245/65/17 WIldpeak AT3W and Black Rhino Boxer 17x8 +40, similair to what youre talking about. And yea, the main difference between the two Wildpeaks is SL and XL load, which XL is basically reinforced, exactly what I want. I got a flat on my stock tires on a mild forest road a few days ago and I want to be extra prepared, but it was also dumb luck maybe too haha

That seems pike a reasonable bet. I bought the vehicle knowing I'd be doing some permanent and semi-permanent modifications, so I wasnt afraid of a little trimming as I incrementally reduced offset and increased tire size from stock to 255/70R16 (30.1", +34) to 215/85R16 (30.5", +10).

That said, if you want zero trimming or mudflap removal, a 245/65R17 on a +35-40 offset should comfortably get you there, and a 255/65R17 on the same offset would, at most rub on the mud flaps or require removing them.

Good luck!

I was just going to pull the trigger on a set of 17s with a 20 offset and slap on some 245/65r17s. Think that would be too aggressive of an offset or have serious rubbing issues? it seems you have a lot of experience with different sizes and offsets

Are Wider Tires Better? Here’s What You Should Know about Wider Tires
March 8, 2020

Do you know narrow or wide tires can affect not only the car’s appearance but also its performance? Here we will answer the ultimate question: Are wider tires better?

Recently, many car owners prefer wide tires to narrow ones as they believe wider tires means better tires in various aspects. It’s been becoming a trend in the automobile industry.

While some think large size tires improve the driving experience, others love it for better appearance. Are wider tires better overall like that? Let us take you to some advantages and disadvantages of upsizing your tires.

Advantages
1. Better grip and traction
Are Wider Tires Better


Basically, you can achieve better traction by doing one of these two actions: having more pressure per square inch or wider contact area with the road. In this way, wider tires offer better grip and traction as they definitely bring you a broader contact area.

However, you should also know that increasing the contact area causes a lower force onto the surface and vice versa. There’s no way you can have both options at the same time. Thus, it means that skinny narrow tires can also provide better traction because it generates more pressure per square inch.

In this category, each type of tires will have its own advantages. Consequently, get the tire that fits most to the type of roads you’ll be driving on and other driving conditions.

2. Improved Cornering

The same aspect of having a wider contact area with the road with the above, wider tires offer better cornering and road handling. It is also because wider tires have a better thread and stiffer sidewalls that they have less vehicle roll in corners.

3. Better Braking
Are Wider Tires Better


Upsizing your tires will bring your vehicle better contact area and grip while it’s running on the road. Thus, this action reduces the braking distance, especially on dry pavements, giving your vehicle a better braking system.

4. Better Appearance

Another perk of upsizing your tires is that it will give your vehicle a more sporty look. Hence, the overall design gets enhanced. Nowadays, many car owners love wider tires as it surely offers a boost to the car’s appearance.

So, are wider tires better really? In fact, everything comes with its own pros and cons, so do wider tires. Here are some downsides of wide tires that you should consider before getting your vehicle upsized.

Disadvantages

1. Increased Fuel Consumption

Generally, the less friction your car produces the less steering effort needed, thus, less fuel consumed. On the contrary, wider tires increase fuel consumption as it generates more friction.
Moreover, wider and bigger tires are obviously heavier, which will require the engine to work more. As a result, they surely consume more fuel.
In this aspect, narrow tires will be a better option as they reduce fuel consumption by generating dramatically less friction.

2. Slower Acceleration and Harder Steering

Wider tires are heavier, which, as a consequence, adds more weight to the car. This decreases the car’s acceleration. With its large contact area, wide tires not only slow down acceleration but also cause hard steering and poor car handling.

On the other hand, the vehicle with wider tires take more time to steer, or return to the center, after every sharp turn. Experiencing harder steering is another downside of using wider tires.

3. Quick Tire Wear

With all those above-mentioned drawbacks, larger tires surely will wear out faster than narrow ones. For instance, wider tires will put more strain on the brake, causing your braking system to work harder. Thus, it wears out faster, which forcing car owners’ to replace them more often.

4. Speedometer Error

By upsizing your tires, you are changing your car standard components. Thus, a car’s embedded technology can be a bit off in terms of accuracy, resulting in errors with the speedometer reading.

5. Safety System Warning

Together with the speedometer reading, other electronic safety aids in the vehicle like EBD, ABS or traction controller might also be affected with their accuracy and timely notifications.

6. Costly

Large tires, obviously, will cost more to make. Thus, it costs more to be installed. Wider tires are also more expensive, comparing to narrow tires because there are fewer options available on the market.

Frequently Asked Questions

1. Question: Which size will a tire be considered wide?
Answer
: A wide tire is any tire that is larger than the specification’s original width for your vehicle.

2. Question: What is upsizing tires?
Answer
: The basic action of plus sizing or upsizing your tire is replacing your stock wheel size with one that has a larger diameter, and still keep the same combined/overall diameter of the original tire and wheel.

3. Question: Are wider tires better driving in snowy weather?
Answer
: Unfortunately, the answer is NO. With snow on the road, it is more important to have more pressure applied than having a bigger contact area. In this way, narrow tires are better an option as they can cut through the snow and provide better traction.

4. Question: In which weather are wider tires better?
Answer
: Except for snow driving, wider tires are generally better in most cases, either wet or dry road conditions.

With bigger sipes, wider tires can trap and remove water better from the road, or any contact surface. Unless you need to drive over a shallow lake, wider tires are better and more practical to drive on rainy days.

On the other hand, go wide is always the most recommended option for dry road driving. On this type of road condition where having more pressure on the road isn’t an essential factor, the bigger the contact area, the better.

Final words

Making the right changes for your tires and wheels to a wider or narrower model from its stock size can be confusing sometimes. However, in the end, it all comes down to your desires. What do you want to achieve? Whether it is for better appearance or better performance, knowing your needs and conditions to have the better and right change for tire and your vehicle in general.
