Hi! I have a 2010 Rav4 Sport model with 235/55 R18" tires on it, and I recently found a set of snow tires locally from a person who had them on their 2010 base model (I'm assuming) as they are 235/65R16" in size. They are claiming that they run 17" tires normally and that the tire place they purchased them from said it was okay to go smaller for winter tires. I'm wondering if they would fit MY vehicle. They come mounted on their own set of rims too. I'm wondering if I can go to that smaller size a tire for the winter months. Any help would be greatly appreciated. Thanks!

0.15 inches difference in diameter.
65mph becomes 64.65
3.82 more revolutions per mile so the odo will be a little off.

should be fine

They make up most of the diameter difference by adjusting the tire profile (aspect ratio tire). Smaller diameter wheel = higher profile tire and vice versa. All the various combinations of wheel and tire sizes available on the 4.3 end up being a within few tenths of an inch from one another with respect to the final diameter.

With a smaller overall diameter your rav will rack up more miles on the odometer than you actually drive although it won't be a lot...I would also mount a front one just to make sure they clear the brakes...also your sport wheels use a different type of lug but than the base steel wheels I believe...you will need the correct lug nuts as well...

I agree with the others assuming you'll be swapping all four wheels. The speedometer and odometer will be off slightly. I highly doubt there will be any clearance issue with the brake calipers. If your current spare is a steel wheel, as is mine on my Limited, the lug nuts are designed to work with either steel or alloy wheels. So except for your TPMS light being on all the time you'll have no issues and I have an easy resistor bypass for that on another thread.

They have a gadget that will store the SensorIDs from the winter and summer tires and reprogram the vehicle, which will also keep the TPMS light off.

I'm a DERP,

you could get clone sensors for your snow tires, give them the same sensor id's as the summer/stock wheels and the TPMS will always work, might get a little squirrelly in the garage where summer and winter tires are near each other, but on the road they should tell you if a tire is loosing air.

I may be wrong but I'm pretty sure all sport models except the sap had a regular 18 inch alloy as a spare...the lug nuts may still work...just something to make sure of...

I would mount one of the front tires to make sure that they clear the brakes. I sure they do as the base came with 16" rims. Though the base model that sported the 16 inchers ran a 215mm and the 17" on the base modle ran a 225mm.
