I have a 2003 Track Pack, with factory Ray's wheels. If i want to increase my tire size, how big can I go on the factory wheels? I've installed the Hotchkis TVS (1" drop), and I want to run 15MM spacers on all four corners. Does this leave any room for a bigger tire? Thanks again for all your input guys!!

 

265 in the rear and 255 max up front on those wheels.

245/40/18 front and 245/45/18 rear is a nice combination. Since your car is lowered, you could also run 255/35/18 front and 255/40 or 265/35/18 rear.

 

The Track model is staggered.

 

and your point is? The sizes you highlighted in red are staggered too, just in height. That setup works great for handling.

 

Like others mentioned, you are limited by the width of the wheel. I believe most tire manufacturers recommend no larger than 245 on an 8" wheel and 255 on an 8.5" in wheel. You would probably be okay if you stretched that by one size, but I wouldn't recommend going to much wider.

 

+2...I've seen 265 fit on the 8.5 rear track rim, but its not factory recommended.

 

All Z models are staggered from the factory from 03 through current.

Agreed. 245 is ideal on an 8 and 255 is ideal on an 8.5, but 10mm over is acceptable, but no larger for most applications.

 

I have 265/35/18 NT05 all around on 8.0/8.5 (stock 08) with 15mm/20mm spacers and lowered - no rubbing issues what so ever. . .

It was larger that recommended for the 8.0 rims - and was a little bit of work for them to get them seated correctly - but the seem to be fine. . . . the rears were easy-
