Tires Rubbing - Roll Fenders Or Camber Or Both ?

Hey guys, I'm running a staggered setup in the back 275/30/20 on a 10 inch wide wheel. I'm not sure of the offset but im guessing its in the mid 40's from what I can gather on these wheels. They were on it when I bought the car. Anyway, I've had a set of Nankang 275/30/20's and they barely barely rubbed if I took a corner way faster than I needed to lol. Even with passengers in the back it wasn't an issue.

I had really bad inside wear on the tires so I bought new tires and at the same time had the tire shop do an alignment and set the rear toe to 0 and removed as much negative camber as they could in the rear. They went from about a -2 to a 1.4 in the rear. Mounted my new Yokohoma 275/30/20's and now they rub pretty bad. It's worse on the right side and it seems to rub on the fenders. With passengers in the back, I can barely get a finger under the fender.

The Yokohama's look slightly wider and aren't stretched as much so I guess they might be a little wider even though they were the same size as the yokohomas. Anyway, do you think changing the camber that .5 of a degree would make much difference? And do you think rolling my fenders would help? Not really sure where I would go around here to get that done.

Just frustrated with these wheels, I would trade these 20's for a light set of 18's in a second. They look good but they've been a pita.

Anyway, how much would going back to -2 camber help and what can you tell me about rolling my fenders. Thanks, Logan.

If you want to stay with very little negative camber, you will have to roll your fenders and maybe even have the shop pull the fender slightly as the roll it. But more than likely with your set up you will still be rubbing. But you won't be rubbing your fenders (as they will be rolled), you'll probably be rubbing your rear bumper liner and mounting tab. The black plastic liner of the rear rubber will start to wear away (not a big deal) but the part that will cause problems and harsh noise is the mounting tab on the rear bumper (take a look at the picture below of my car). I have yet to resolve this tab issue, but I plan on cutting a small corner of the metal and plastic off then rounding it with a file, rubber hammering it up slightly and then seal with Rustoleum or touch up paint to prevent corrosion.

I personally do not think that going back to -2 degres of camber will solve your problem.

You have -1.4 in the back? or +1.4....??

You should be about -1.5 rear and zero toe for wear...and that should be good...not sure if it will make the tires fit though. Try a conservative roll first and then get harsher if that still doesn't work. A FS thread would solve the problem

-1.4 with zero teo.
Yeah haha I'd like to sell them if I can't make them fit!
I've called every body shop around and no one will roll my fenders
Might end up renting the tool offline and doing it myself
Anyone done this ?

Went back to -2 camber and had them set toe to zero ... Went to a different place to get alignment and the other place's machine must have been wack because I got way different readings. Anyway, -2 camber helped a ton. It only rubs now if I take a corner way over my head. I think if I roll the fenders it will be gone totally.

It's easy to see if it's truely the metal fender's lip that is causing the problem. The metal edge will have a thin layer of rubber on it if it's the thing that's rubbing.

Oh and if you can't get your fenders rolled, it's cause you're going to the wrong places. Any wheel shop will have the tools and experience to roll your fender. Typically, busy shops don't roll fenders.

If you do DIY, have a person help you with the heat gun while you roll. It's a whole lot less hectic when you don't have to juggle two tools and eye for perfect body lines.

Yes, a 26.7" tire OD with a 10" wheel is going to have rubbing issues.

Hello everyone,
i am looking for a little bit of advice since i am having kind of the same issue with my rear fenders. at the moment my mazda is sitting on Tracklite Clutch rims 18x8.5 in the front and 18x9.5 in the back with 235 40 18 front and 245/40/18 sumitomos. i've also installed a 20mm spacer, i have rolled my rear fenders quite a bit and the rear still rubs quite a bit. i have stock suspension and at this point i'm not really sure how to correct it? do you guys think i should have a tire shop play with the camber to see if this helps? i really like to keep my spacer as the car looks really good i think. any advice will be greatly appreciated.

Daniel.

Use a smaller spacer. There aren't really 10 ways around this.

yes, that's an option, but it is not feasible. if i go with a smaller spacer the factory wheel studs may extend past the surface of the wheel spacers, then i would have to cut them and or get smaller studs. i would like to try to avoid this at all. thanks for your reply, but it wasn't very helpulf at all. and as for your sarcasm i would ask that you keep it to your self, all am asking for is for advise from some of the guys that have dealt with this kind of issue, that's all.

Your choices:

Change or remove spacers
Change wheel's and or tires
Alter wheel arches and fenders or increase camber

Those are the choices you Have. ..

Don't whine when someone pointd out the obvious

? The studs may extend past the surface of the spacer...? What do you mean? If you use a thinner wheel spacer, you wouldn't need to do anything to the studs.
