i personally like the look of the stock rims. i was wondering though what is the biggest tire you could fit on the back and front. i know most people only go up a centimeter on stock rims to avoid it starting to curve in. any info is greatly appreciated
thanks

I see from your sig that you have the coupe. Which tires do you have? The 17's or the 18's?

Try www.tirerack.com and look at their alternate tire sizes for your size wheel. That'll get you close. If you want something bigger, look up specs for a particular tire on their site. The specs for the tires generally give recommended, minimum, and maxium rim widths for each size.

How wide a tire you can put on the wheel is also linked to the tire's profile. (Taller tires can stretch to a wider range of rims, while lower-profile tires have a narrower range.)

This tool (http://www.miata.net/garage/tirecalc.html) is useful for comparing tire sizes to find something that's close to the same overall diameter as the stock size.

For instance, on my stock 17x7 sedan rims, a 255/50R17 will fit the rim, but a 245/45R17 will not. However, a 235/50R17 is much closer to the stock tire diameter (215/55R17), and is the better choice. Also, just because a 255/50R17 will fit the rim, doesn't mean it'll fit the car. A tire that wide and tall will most likely have serious rubbing issues on the sedan.

There was a post on this some time ago. 245/40 front and 275/40 on the back should fit the 18" stock coupe rims.

The 245/40's in front are fine. 275/40's out back are a stretch (no pun intended). They might fit, but there will be side wall buldge. The specs for a 275/40 call for a 9.0" min. rim width. The max correct size tire for the rear is a 255/45.

How about the coupe stock 17" rims?
Is 245/45-17 front, 255/45-17 rear okay?

The difference in circumference is < 1%. I'm just wondering if the tire is too wide for the rim.

 

245 may be the widest you could go on a 7.5" width rim. I'm not sure though. May even be 235. But I know you can't do 255

i have 245-45-17 on my stock 17"s coupe wheels and they are 17x8 can i go bigger in the back? and run the 245-45's in the front?

 

I just up sized both and put 245/40f and 265/40r. The rear is an odd size but the PS2's come in that size. Has a little side wall bulge in the rear but I think it looks sweet! And no problems with the VDC.
