what is the widest wheel/tire combo i can possible fit on all 4 corners?

Inquiring minds need to know.

I have no idea, but I'm calling dibs on your 18's. :D

Looking at all 4 corners, its a balancing act between strut rub in the front and fender rub in the back. Without suspension work, I think you're looking at 18x8.5 wheels with 40mm offset. 245/40/18 is safe and 255/35/18 is possible. That puts the inside of the wheel no closer to the strut in the front. You'd most likely need to roll or grind the fender lips in the back.

Still a work in progress, but here are some ideas:

that just confused the living shit out of me.:cry:

on the front you're going to be limited because of strut rub but in the back i have 17"x9" with 275 Nittos and no rub. i did roll my fenders but i don't think i needed to. there's about 3/4" clearance on the inside so i think i could have gone a little wider

bnb550, I'm confused too. You're looking for a non-staggered setup, right? All 4 corners with the same wheel/tire combo? That's what my reply was based on, but if you're considering staggered, then take a look at what these other guys have done.

Sorry. I was considering 265/40-17 on 17x9 +42 all around, but I decided to go with a staggered fitment instead. Clearance to the rear fender lip will be an issue with almost any wider tire & wheel combination. This will require fender rolling, especially if you want to lower. In the front, clearance to the strut will be an issue, requiring work-arounds such as different wheel offset, wheel spacers, slotting the strut bracket holes, and/or offset strut mount top bushings. If you want to lower the front, the fender lip also becomes an obstacle, requiring compromise on tire section width. Doing a rotatable all-around fitment is a juggling act between the different obstacles front & rear...if the wheels don't have to be the same for tire rotation, front offset "wants" to be in the 35-42 range while rear offset "wants" to be in the 52-55 range.

If you're asking what's the widest that will fit without mods, the answer is 245's for sure, maybe 255/40-17 or 255/35-18. I think there was a fairly recent thread about 255/40-17's all around. I did a LOT of research before pulling the trigger on my wheels & tires! This car is a major challenge for tire fitment, very hard to acheive tread width sufficient for a 400hp car with an all around setup.

get the stickiest 245's you can and you'll keep up. ;)

"not enough information given"

1. Are you going to stick with stock ride height, are you willing to go up a teensy little bit, or are you planning to lower the car?

2. How much front camber do you need/want/lust for?

3. Is it legal for tires to stick out past the sheetmetal on cars registered in your state?

3. Is it legal for tires to stick out past the sheetmetal on cars registered in your state?1. Stock ride height probably, if anything, lower it an inch at most.

2. No clue.

3. Don't know, but whatever setup I decide on would be strictly for autox use, so it doesn't really matter.

That's what I ended up doing for now. Michelin Pilot Sport PS2s.

I was just going to post a new thread about this exact topic. I'd like to fit a 17x9 with a 255/40 Toyo RA1. The 235/40-17s on stock 17x8s aren't cutting it.

Pedders no-drop springs with Pedders GSR/Big Bore or Koni dampers


2. How much front camber do you need/want/lust for?

-1.5* to -2*.


3. Is it legal for tires to stick out past the sheetmetal on cars registered in your state?

These would be track-only.

I don't have the exact link, but run a search for my screen name and you should find my posts detailing how I got 275/40ZR17's on all four corners. They are even BFG! No rubbing and no rolling the rear lip.
