I have a RAV4 2020 LE FWD RAV4 with 17“ steel wheels with hubcaps and would like to put the 18” TRD rims on it (part # PT7584220002).
I went to a dealer and they gave me many excuses for not selling me or making the change. One of their reasons why I should not make the change from 17“ to 18” was because the speedometer would not work properly due to the change in tire diameter. Other reasons were possible problems with the efficiency of the transmission and suspension.

Once I left the dealer I was consulting with an automotive technician and he told me that to correct the situations that the dealer mentioned, you just have to do a remapping or reflash the ECU of the RAV4 with the new information of the new tire diameter.

I emailed the dealer and the customer service person who attended me, but they never got back to me.

I need to change the tires on my car and I would like to change the rims at once, but I don't know if doing this will be prejudicial.

Any advice is welcome!

That is a bunch of b---. If you do a search through the forum, you will find many people changing the wheel and tire size.

1. As it comes from the factory, all Toyotas show a speed about 2 MPH higher than the actual speed. You can verify this by using a GPS speed app on a cell phone such as Speedometer. Putting a slightly bigger (increased diameter, not wheel size) tire on the RAV4 will eliminate that difference. Your speedometer will be more accurate. Both TireRack and Discount tire, on their web sites, have tables that show how much your speedometer will change with different size tires.

2. Many RAV4s already come with 18" or 19" wheel/tires, so changing your RAV4 to a size that already comes from the factory will not affect the transmission or suspension in any way. Depending on what new tires you get, they may affect your gas mileage.

3. As far as I know, there is no way to change the computer settings in the RAV4 for a different tire size. If there is, it would be through Techstream (the service tool the dealer uses) or Carista (a clone of Techstream). But why bother if the speedometer reading is more accurate (#1 above).

Since many RAV4s come with 18" wheels, and 18" tires are more readily available verses 19" tires, I say go for it. That is a great looking wheel that many on the forum have gone with.

Now you will need to decide on what tires to get. There are many good suggestions on the forum, so look those up. A lot of what you get depends on where you live (snow/winter verses deep south or desert) and what you want to do with your RAV4. You will get the best prices online at Discount Tire or TireRack (which owns Discount Tires), which will ship your new tires directly to a Discount Tire store near you for installation; you don't need to bother the dealer for installation. After installation, Discount Tire has great service including free flat repair, rotation, etc. Also, Tire Rack has free road hazard warranty, so if a tire gets damaged, it will be replaced for free at a Discount Tire store.

For snow country, probably the best tire would be the Michelin CC2, Pirelli Scorpion Weather Active, or the Falken Wild Peak, all of which are three peak snow rated. The Wild Peak would also be good for mild off road (forests roads and the like). For a bit warmer climate, it is hard to beat the Michelin Defender.

This looks like the Same aftermarket satin black wheels (Fastco Replika R243) sold at my Toyota dealership as an option for the Rav4. Everything else FKHeath stated. Dealership lied to you Or is incompetent.

Try TireSize.com - Compare Tire Sizes, Specs, Prices & more and use the calculator entering your current OEM size of 225/65/17 and also www.wheel-size.com
I went from 19” on our Limiteds to 17” for winters using these websites. And for all my past Corollas, did the same for winters using these using these websites for appropriate wheels sizing for model and year of vehicle and appropriate tire size to keep speedometer, ABS, etc working as OEM size.

Tire size and wheel size are 2 different things. You can change the wheel size and keep the overall tire outside diameter and width car will not drive any different. First let me explain tire sizing.
Your current tires are 225/65r17. This means that you have a tire that is 225mm wide with 65 aspect ratio, running "R"=radial tires, and a 17" wheel. The aspect ratio means that 65% of the width (225) is the height of sidewall above the wheel. So to convert that to "American". 225mm=8.86"x65%=5.76"x2=11.52+17=28.5". You have a tire that is 28.5" in diameter and 8.86" wide. Not exactly as each tire is made slightly different, but close enough. You can find the exact specs for each tire. Tire rack.com is a good place to start.

The outside diameter of the tire is the only thing the car cares about with respect to speedo/odo, torque, shift points...

Aspect ratio come in increments of 5 and is directly related to wheel size. Thus the following sizes are ALL the SAME SIZE TIRE.
225/60r18
225/55r19
225/50r20
225/65r17
225/70r16...

See how that works. Of course they might not make every size tire as some are not practical or popular anymore. So go buy your 18" TRD wheel and get some 225/60r18 tires and get it done.

Since you seem like you will use this info, I will drop some more for you. You will also need new lug nuts. The steel wheels use an "acorn" type nut with a tapered interface between the wheel and the nut. Something like this:
Image

Toyota alloy wheels use a flat captured washer nut like this. The wheel/nut interface is FLAT. You CAN NOT use a lug nut for a steel wheel on an alloy. But in a pinch you use the alloy wheel nut on a steel. Like for your spare, as you will notice it still has the tapered surface.
Image


Since you are planning on getting a RAV4 wheel as a replacement I won't go into wheel specification as it should be a direct fit. But I will give you some tips on buying wheels. If you go to toyota to buy OEM wheels new, expect to pay $3-500+ EACH. Instead you should look locally for "take off". Wheels people took off their cars when replacing with fancy aftermarket. ARe you dead set on those 18" TRDs. They do make some nice 17" alloys. Look on facebook market place and craigslist. For example.

Here is a black TRD wheel. But I would be very cautious and only get wheels that came off a RAV4, not one that claims to fit a RAV4. Reading the description I know that this wheel will NOT fit all the cars that are listed. I believe these are replica TRD wheels and not OE. Not that I have an issue with replica wheels if they are built exactly for a RAV4

You can try ebay too but the prices will be higher.

The part number cited in the the first post of this thread (PT7584220002) is genuine Toyota, available everywhere. MSRP is $250, but available for less at many places. That same wheel is also available in a bronze finish which looks spectacular!

So sad dealer is full of it and your consultant so-called automotive technician doesn't have a clue

Wheel/rim size is whatever you can fit. Tire size is how you pick a rolling diameter. The Rav came with a bunch of wheel sizes. So, 17's, 18's, 19's..... can be used without worry.

If you want a little more height, you can use a taller tire with any of the wheel sizes.

The skinny 225's don't fill the area too well. Toyota uses 235's with the 19's. Once these tires wear out, I'll be switching from 225/65/17 to 235/60/18 on whatever hub centric aftermarket wheel she likes. 19's don't offer enough sidewall for these roads around here.

Yes I wish our Limiteds came with 18” not 19”. It’s surprising not harsh on racked bumpy roads but 18” is a nice sweat spot IMO. And with the gloss black XSE wheels or other gloss black wheels.
I don’t mind the 225 width on my son’s XLE but agree 235 -245 would be a nicer

Thank you all so much for your answers, help and advice. You guys helped me a lot in making my decision.
Searching online I think I found a good deal. Now all I need are the lug nuts. I already checked and the tires that come from the factory with that rim are 225/60R18.

You are able to use same original factory lug nuts if the wheels you purchase are flat mount or conical like steel wheels and some alloys. 60 degree conical I believe is what the original lug nuts are. If conical wheel, the degree of the cone must match the lug nut. Toyota lug nuts for alloys are flat with also a conical seat. You may not like the look if using on a conical seat wheel as the flat part/washer of the Toyota lug nuts will not be flush to the wheel.

What a load of horseshit from the dealer.
The 225/65R17 and 225/60R18's are the same size. Secondly, Toyota sells this car with 235/55R19 which is larger in diameter than both the smaller variants. What's even more funny is, that even the 235/55R19 reads too high - IT HAS TO BY LAW! So even if you ended up running a 235/60R18 just because you like the look of a slightly bigger boot, it will still overread. You'd need to go at least a 255/60R18 or 225/65R18 to get anywhere near reading on point.

Tell your uninformed dealer to pound sand. If you have a different Toyota dealer somewhere, just call them and order them. I'm guessing they won't even ask you what car you have. Just be direct and tell them you need a set of the TRD wheels for your Gen 5 RAV.

Your dealer must really be stupid if they don't want to sell you 1000$ worth of wheels.

Toyota uses lug nuts with flat washers on their alloy wheels. That is at least the case for my R4P 19's. My aftermarket wheels are as most, 60 degree cones.

Your OEM flat washer lug nuts should also have the conical shape designed to be used for either type of mount.

Also as a note for others, Toyota OEM lug nuts you have are likely two piece meaning the outer Chromed finish is on a thin tinned metal glued over a solid piece and with regular use of impact wrenches, the glue bond can weaken and if not caught before the chromed cover is lost. It can make removing the lug nut more difficult. I learned this on my 2005 Corollas and from Toyota, bought the Made in Japan lugs at about $3.50 CAD each and replaced lugs on all our Toyotas Even my Made in Japan Previous Lexus came with two piece lug nuts. To check if two piece or one piece, look upwards between the washer and flared flange of hex nut and check for end of thin cover wrapped around curve of flange.
