I haven't measured the width but they're stock C5 wheels (18"). I want to put the widest MT ET Street DRs I can fit on there. Anyone know? Here's a pic:

285's are the biggest width for the 9.5" wide wheel.

you can fit a 315 on a 9.5 tire which is what alot of cobra guys do on their stock rims. its not recommended but it will fit with a lil stretching. i am going 305's on my 9.5's

No, they will not fit well at all, MT's run wide, and most of the cobra guys are running Nitto's which run thin. I wouldn't risk it, and whats the point? The tires will bulge, won't have a full contact patch etc.

you think 305 mt street radials would be acceptable?

Okay then what would be the biggest size I could safely fit? 295s?

This thread is going to get locked. The wheels you have are 18 x 9.5. I have the same ones on my Formula. You can safely fit a 285 on there. That's what I have now, but will be putting 295s on there as I have been told they work fine. Keep in mind that is not recommended and will probably bulge some.
