Sorry if I'm bringing up an old thread but I can't seem to find what I'm looking for. But I just purchased a set of AFS cobra wheels in 18x9 and 18x10.5 , I was just wanting to hear from you guys what's the widest tire I could run without rolling fenders. I'm lowered on H&R sport springs, and have the IRS bolt mod. I've been looking at 295/35/18 but would love to go wider. Thanks guys. Pics would be awesome too!

Depends how low you are it if you want to play it safe and you are dead set on not rolling your fenders then a 315/40/18 nitro nt05r would fit fine.

The Toyo TQ, R888, ET Street, etc, will work better but they all run extremely wide.

Hmmm interesting. I heard that too. I looked at the 295/35 in the nt05 and they look so narrow. Ill like the look of the kdw2 in the 335/30 but I know they're prob too big. Damn

I recently put on TF 18x11's in the rears with R888's 305/35/18's. I have H&R race springs with all iso's in place, and low profile irs bolt. I've only driven the car a couple miles since then, but no rubbing yet. Hoping I don't have to roll the fenders.

305/35 or 295/35 is a safe bet. 295 may be a tad stretched on a 10.5, 305 is the right size.

Hanks guys. Been still doing research I've seen some people saying there running a 315/30 with just irs bolt and maybe a spacer. Anyone running a 305+ nitro or toyo that could check in?

I run wheelreps 10.5 in deep dish cobra reps in the back w/ 315 35 17's on HR sport springs w/ all isos in place w/out rolled fenders, low pro is bolt and no rub. I have never ran 18 in rims before so idk how much of a difference it is.

My 335's on the AFS's rub the fenders slightly. I am going to need to get them rolled at some point. I have H&R Race springs one with one iso out, low pro IRS bolts and a 3/8th Spacer.

I'm gonna mount these 295/35 nt05s and I'll see if they look to narrow to me, which they prob will.

OP...I've got basically the same setup you're looking at. AFS 18x10.5's and H&R's. Running a 315/30 R888 without rolled fenders. No issues and no indication that I've ever come close to a problem. Like someone else said, 305's would probably fit the rim width perfectly as the 315's bulge a little. But if wiiiidddeee is what you're after, 315's will jive.

Looks like my fenders need to be rolled. Doesn't rub just driving normal. Hard acceleration it has.
