What are the largest tires that I can fit on my 17" stock wheels without having rubbing problems? Currently I have 245/45R17 on and would like to upgrade to a larger tire without purchasing new wheels.

thanks for the responses.

I think most people just put on wider tires on the rear...they are 275/40/17 I believe..Nitto 555s. Those apparently will fit on the stock wheels....the other brands from what people have said on here require wider wheels.

I put P-Zero's on 275-40-17. I had to roll fenders slightly though. Traction is excellent.arty:

I have 275 40 17 Nitto DR's for the rear.....no problems.

how about 265's

If I go with a 265 rear tire, should I go with a 40 or 45 aspect ratio? I imagine if others are getting 275's on 265's should fit without rolling the fenders, right?

275/35/18 BFG drag radials in the rear work well for me. But I did need to roll the fenders. On 9.5 inch wide

what size rim you got?

Here's a tire size calculator I found on Miata.net when I had one of those. Works for any car of course; you plug in the tire you have, or stock size tire, and then it calculates the difference, profile and width for whatever you want to go to.

Helpful if you want to keep speedo close to reality- - -

245s are the widest you can fit on the stock 8" wide rims. Go to http://www.tirerack.com and look for the tire sizes you want. Click on a tire and it will give you rim sizes that will work.

The car already understeers in the stock set-up. Even though larger tires in the rear will improve tractions turing acceleration, won't they make the car understeer even more?

Hey Johnebegoode,

I like your LED conversion. Where and how much? I'd like to do that to mine to match my red interior. The lime green just doesn't quite look right. Also, did they do your stereo too?

If I go with 265/40/17 on the rear how much more road noise will I get? The salesman at Discount Tire told me that they would have a lot more road noise if I went with the 275/40/17.

Could you get away with 265/40 17 on the front and rear? I want to be able to rotate my tires regularly. Guys running the DR's, are you just putting them on the back and not the front? I kinda want the car to be symetrical.

Understeer is a function of the front tires not having enough traction. The front tires skid forward through the turn instead of gripping and turning like they should. I suspect the car would be much more prone to oversteer if it had proper tires on it to begin with. The all-season tires that pontiac puts on there kinda suck. The traction is horrible when they are cold, and only slightly better once they get warm.
