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.

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

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.

Get a drag-radial. Nitto will last a long time and they really hold better than a street-radial.

(fyi: 275 drag radials have been into the 7's in the 1/4)

I'll look around and price the 555's, I have 10.5/18 inch wheels now do you guys think the 305/45/18's will fit in the fenders?

305/45's sound REALLY tall. :think:

+2 size doesn't matter as much as rubber compound does.
