Any problems running this setup on stock rims? My OEM tires are about done for and I would like to go just a hair wider.

Thanks!

 

195-60-15 would be the way to go. They are an acceptable substitution and will help fill the wheel opening a little. There is less than 2% change in diameter which is ok for the speedo.

 

No probs! http://www.miata.net/garage/tirecalcold.html 225/50 would even work.

 

Might be a little wide for stock wheel, no?

 

I would think the 225 is a little wide for stock wheels. A 205/55 would be about as wide as you would want to go and that may be stretching it some. There are two problems. One is the tire fitting the rim and the other is the fitment under the wheelwell. I have 38mm offset and it looks like I will need OTG shims for the rear. Maybe not, but it looks close.

 

I've ran 205 50 15's on all 4 wheels with no rub at all. They also fit the stock steel wheels nicely. I recommend them.

 

Thanks TJ. That was what I wanted to hear. Installed TRD springs this weekend and now I think it will look better with the OTG shims on the rear. That should take care of any possible problem in the back and it is nice to know the front should be rub free.

 

I am running a 195/ 50/ 15 on stock wheels with just a little rubbing on full turn to the right but that is b/c I have right at a 4inch drop. I did notice gas mileage went down a good bit.

 

I went with the 195/60/15 on a 15" aluminum rim, lowered with H Techs, and the ride and handeling is great. Speedo was checked with a GPS and was only 1mph slow, instead of 4mph as she comes from the factory.
