size matters

stock94 · 11-30-2008, 04:19 AM

Gotta 05GT, right now it's got a set of roush 18 by 10.5's , anything under 45mph. it just blows the tires away. What is the largest size tire I can fit on that rim? Any suggestions, not gonna do alot of racing so I need something that will last a descent amount of time.

By the way I'm kinda stupid on the back spacing kinda stuff.

i know a 285/35/18 will easily fit on a 10.5 rim and nitto makes it in the 555

I have 335's on my 10.5's. The wheel shop said not to bring them there again lol

Also I would do a drag radial, not much traction from any street tire

Thanks for the suggestions will check some out. At this time I have 275/45/18

That car is supercharged, right? No regular street radial is going to hold. It's more an issue of tire compound than size. A 275 drag radial will work better for you than a 315 street radial. I would put a 305 (do they make a 315? The 335 might be a little too wide.) Nitto 555R on there.

For the record, a drag radial that's a little too wide for the wheel will feel sloppy in turns. I had a 315 on a 9" wheel and on sweeping turns the back end felt "wobbly" for lack of a better word.
