Well now I'm stuck knowing 315/30/18 may fit.. I have 56mm offset 18x10.5" wheels. The price on 315 r888r and/or TQ is cheaper than the 305/35/18 555r and you get more tire for the money. Another bonus is tire height is very close to stock for running ABS, which I still have.

Worst case i guess I have to roll my fenders (hopefully not), BFH mod, and trim my bump stops.. I looked all over for info on people running 315/30/18 and I get a ton of threads asking about fitment and then they never come back and say if it worked or not lol. Can't find anyone who has done it without being lowered, which ends with them having to roll fenders every time.

Do most body shops roll fenders? Where is everyone getting it done?

Alot of guys end up doing it themselves with a special fender rolling tool. I believe some members offer to rent them for a fixed price on this site. It's not too difficult of a process. If that's not for you, I would think a body shop could handle it. Good luck.

Depending on the brand of tire between +43 and +45 offset is needed

So having 56mm offset will create more potential of rubbing and needing modification? Just want to make sure I understand. Thanks for the info

yes, you need 11mm spacers to get to +45mm offset

So based on that should I stick with a size similar to what I'm running now? I currently have a nitto nt05 295/35/18. I could run a 295/30/18 r888 or a 305/35/18 555r since those tend to run smaller than most?

Given that you're only lowered via heater hose... The tire will be running right at the bump stop. Even with trimming it was close with my 285/35 tires on 18x10.5 +58 wheels.

I run 20mm spacers now. Tires/wheels flush with qtrs now. Adjustable panhard required to center it just right too.

For 295s at least run at least a 5mm spacer to be safe on the inside and play with panhard bar. Outside you're fine

Sounds good I will stick close to my current size then. I'm willing to BFH mod and cut my bump stops, but would prefer not to run a spacer and roll fenders. I do run longer wheel studs so a spacer could be a good back up plan for me if I can't get it to clear. I'm thinking the 305 555rs will run closer to a normal 295 so i may just go that route so I'm not running a 25" tall 295/30/18 which may look a little short in the rear. Never knew tires would be such a hard decision lol

Bfh isn't needed at 295s with 5mm-10mm spacers.You don't want to cut the the bump stops off, they're needed. There's plenty of room to run 295s without rolling qtrs. And remember panhard suspension moves in an arc... So be prepared to factor that in if rubbing does happen somewhere.

My 295s fit right now with no rubbing or spacers.. when I jack the car up it does hang on the bump stop though. Maybe my 295s fit because they are nittos and run small? I think cutting the bump stops is more or less trimming the lip that sticks out, which doesn't look too risky to run that way.

I was just reading a thread where 315/30/18 fit with the same offset as my wheels with just BFH mod and no spacers.. bump stop may have been totally removed though. So many different reviews and threads that it makes it more confusing lol. I'm about to roll the dice on 305s or 315s and do what is needed to make it fit.

dojob

Correct, when you jack it up or the suspension articulates (Like going in/out driveway or an entrance) it will hit.

Trimming the lip helps, yes. Just don't completely remove them

315/30/18 with a 56 offset and 10 mm spacer should get you right where you need to be. Minimal rolling and hammering

It's all starting to make more sense now.. does the 10mm make it look kind of stupid is my only concern now. I will see if I can find some old threads, I'm sure I'm not the only person who would be running spacers. Fender rollers are about $50 on Amazon, so it isn't the end of the world if I do it myself. Thanks for the info!
