Default Whats the widest and tallest tire that fits C5Z rear wheel?

Anyone know? 18x10.5

Thinking about MT ET Street R

They have 325/35/18 and 305/45/18

Would either of those fit? Hard to find a straight answer on whats the limit. Most people just guess anyone know for sure?

Since you are on a 18x10.5, I'd say a 315/30/18 would be about as big as you could go. The 10.5 width being the limiting factor on running a wider tire. I run a 315/30/18 square on 18x10.5 Speedlines.

305/40/18 is the biggest I would run on an 18x10.5... that tire will probably be pulled in on the outer edges so you will lose a bit of contact patch

315/30/18 is what I have now. Seems like theres more room.

What do you think is the best size for street traction on drag radials with the 18x10.5? 305/40/18?

mickey thompson makes an et street s/s in that size... how much power is you car making and how do you intend to drive it?... the et street s/s is a great tire in the right scenario, if you do any driving in rain, want a tire that will handle fast corners, and want long life then they aren't ideal

Car is twin turbo C5z currently at a conservative 700rwhp. Drag only on street in mexico. No cornering. Limp home in rain is possible due to FL summer.

I run a Michelin PS2 in 335X30X18 (on 12X18" wheels) without and problems or interference. It does stick out about 1/2" and looks like it will hit the fender, BUT when the wheel moves up into the fender well under compression, the tire clears the fender due to camber gain.
