I have Michelin 185/60-15 on the front and 215/60-15 on the rear of my 2003 MR2 Spyder and yes I bought 15" chrome stock wheels for the car just after purchasing the car. The tires transformed the ride, the ride is much smoother and more comfortable now, and the tires last a very long time with the 800 tread wear rating compared to the 140 tread wear rating of the original tires. Also, these tires fill much of the wheel well space that was caused by the OEM tires. With these tires I normally get between 35 and 41 MPG. I highly recommend using 60 series tires. These tires are the same width as the tires that originally came on my Spyder. Wider tires than stock causes more road noise, gets less traction on wet or snowy roads, gets less gas mileage and normally cost more. I have found that the "sweet spot" as far as air pressure goes is 25 or 26 PSI for the front tires and 30 or 31 PSI for the rear tires. Because of the low weight of the MR2 Spyder a well balanced tire is very important so I always have my tires "Road Force" balanced.

I have the SMT Transmission and love it. The extra gear was much needed plus the taller rear tires gives a 6.5% decrease in RPM as well. At 70 MPH in 6th gear and with the rear tires I have the RPM is 590 less than with the five speed Spyders.

The point of this is to put the info all in one place. This is for non-stock sizes, of course.

The info needed is:
-Wheel brand and name
-Wheel diameter and width (front size & rear size)
-Offset (front & rear if they differ)
-Tire size (front size & rear size)
-Lowered or not
-Rubbing? (Categorized as either "Often", "Rarely" or "Never" to keep it consistent)

Those running spacers or modified fenders need not apply - I don't want to over-complicate things. I'll update this first post to reflect the info, and maybe sort them by size, so people don't have to scroll through pages of posts. I'll
later remove these instructions. I realize different tire brands have different construction dimensions...but I wouldn't suggest mentioning tire brands unless they are race compound tires since they can have the really square sidewalls.

I'll get it started. Please contribute. Multiple contributions for the same sizes are fine and encouraged. But please, no contributions that are missing info.

There isn't much of a selection in 18" if you want tires that are close to the OE overall diameter. For example, 205/40 and 225/35 are close, but I don't know if you can get them in a set.

Hi everyone - New to this forum though a happy 20 year owner of same MR2. My question: The rear wheels of my 2001 spyder are crapped out. I wish to switch to the 2003-2004 size rear wheels. What size are those wheels? Will switching affect balance, e.g. oversteer, and would I need to change setup in any way? (I plan to keep the original fronts) Do you recommend the Potenza tire combination and if so in what sizes? Hope someone can advise! Thanks! Peter

The rear wheels for 2003+ are 16" x 7". 205/45-16 tires will be the same diameter as 2000-2002 OE. The OE tires for 2003+ were 215/45-16, but you may not be able to find them in a set with tires of the right size for the front.

Wider rear tires will stabilize the car, and hence reduce oversteer. Don't know why Toyota decided to mount a larger diameter rear wheel. Maybe because a lower profile tire would have a stiffer sidewall. If you find out, tell me and we'll both know.

If you're asking about fit I'd say that's totally appearance. If you're asking about light weight, best grip, paired with what alignment & suspension setup then it falls under performance. This thread doesn't really address any of those things, it just lets you know what will/won't physically fit. At least it's not full of 350z style stance setups with "yes" degrees of negative camber
