I just put in some 2010 Chevy S Camaro rims on my TL. They look great but I get a little rub in the rear when I hit a bump and on the interstate. Do I need to roll or pull my rear fenders? I'm new to this, please help.
FRONT-Rims: 20x8 +35 with 245/45/20
REAR-Rims: 20x9 +40 with 275/40/20
I got these for a steal...$400 for all 4 with new tires...I don't have a ton of cash and just want to make what I have work.

 

pull the rear wheels off and physically check where it's rubbing
spent black rubber will be evident, or look for rubbed off paint, etc.

when you know where it's rubbing, THEN you can take appropriate actions.

 

I just took a look at it. There is black rubber splatter on the upper, inner portion of the fender lip and rubbing on the outer area of the tire. Rubbing is right on the edge of the tire.
Rubbing is only on the edge of the tire and right at the top of the fender lip.

 

Great pictures and it shows what is rubbing!
if you squat and look UP at the fender lip, you'll see that the lip is partially rolled. the sharp edges of the unrolled lip is cutting into your tires.


you can continue to "roll" the sharp lip upwards to round it and roll it up. you would need a "rolling fender machine" to work the fender correctly. you can buy a brand named one for about $200...or you can buy an aftermarket one for $50.

basically; this machine attaches to the hub and has a rubber wheel on the end. you tigthen the contraption until the rubber wheel is on your fender...then you heat up the metal with a heat gun and roll the machine.

the rubber wheel bends the metal upwards, preventing a sharp crease cutting up your wheels


you could also "pull" the fender by taking a few phone books, jacking up the car and putting the phone books in the gap of the wheel and fender. slightly let the jack down, and the phone books will pull the fender out. but of course, this will lead to bent fenders, so be careful

 

Thanks...Now the harder question is the best DIY roll technique...I've seen the youtube videos with the bat and heatgun, phone book, etc. Any ideas on what is the most effective and easiest method? I guess I'll be tackling this project this weekend.

 

i did the bat and the phonebook on my car.
taped up a metal bat and went to town. pretty easy as i went slow.

rolling is first.
pulling would be your last choice.

so i rolled my fenders, but still on the occaision would rub...did the phone books and it pulled the fender enough to clear!!! but i had stacked phone books and the way the metal manipulated,it crushed the tiny piece where the door meets. looks funny. and some one could tell i tried to fuck with that.

eventually, i would want to weld a wider piece on.

 

Did you heat the paint with a heatgun when using the bath method?

 

i didnt have any cracked paint. but i did get warped panels from pulling with the phone book method.

 

Seems highly unlikely that rolling the fenders alone is going to eliminate the rubbing problem. Look how far they stick out... you will probably need to put some negative camber on them so they they tuck into the wheel wells a bit.

 

I can tell you right off the bat that it’s rubbing due to the tire sizes. 275/40 is pretty wide. Usually with 20’s most people are running 35 series and around a 245/255. The fronts are also very tall with that 45 sidewall. If I was on a budget, first move would be to get the rear fenders rolled flat. I can tell you smaller tires would fix your issue as well.

Good luck!

 

Thanks guys! I'm going to try and roll the fenders this weekend to see if that helps at all. Next step will be the infamous phonebook. I called around to a few shops and no one is willing to pull or roll my fenders, especially since I didn't buy the rims from them. So, I'm on my own.

One other thing...I took another look at the tires and it seem as if the driver side is much worse than the passenger side. Any ideas.

 

+1 Tire size

 

Uneven tread wear is most likely due to the previous owner in need of an alignment.

 

Simple roll & pull will take car of the problem. Use a real fender roller and a heat gun. Don't use a bat. Your car deserves better.

 

UPDATE: I rolled the fenders and changed the tires to 245/45/20 on the rears (9 inches with +40 offset). I went with the 245/45/20 instead of the most common 245/35/20 because the tires were an even swap with the ones that I already had on...so basically no cost to me. Switching to the 245s vs the 275s that I had on originally saved me about an inch or so but I still get rub when going over bump and zooming on the interstate. I think the culprit is the bumper tab as it appears to be slightly bent upward. I'm going to try and bend it all the way up or shave it off. Anyone else have any success with the bumper tab or any success with 245/45/20 and 9 inch wheels with 40 offset?

 

You’re probably the only one running that y’all of a tire on a 20” rim. That’s the size for the factory 18’s. Running the correct size 35 series will decrease the height of the tire and the vehicle by almost an inch. 24.5mm to be exact. You would have no problem with rubbing with the rolled feeders.

 

 

Do you have any pics of these tires on your car? Here are the specs of the tire you put on. Lol 7.5% is a huge difference. When your speedo says 50mph, you are actually going almost 54.
By going that large you may have computer controlled problems like abs failure, transmission mishifts etc. Or you might not. Who knows lol. One thing is for sure though, Acura didn’t test the TL with those size tires so they are outside specs, meaning uncharted territory. Next time don’t buy what is convenient, buy the right size for your car. 245/45/20 all around...light rub on deep bumps..decided to repaint them matte black and do my sideview mirrors the same.

It only rubs on deep potholes and changes in elevation when highway driving. I'm thinking it's the bumper tab. Anyone else had success with this fitment and/or removing the bumper tab?

 

I believe you are the only one that runs 45 series with 20 inch tires, running 275 is not a problem, the rubbing problem is the sidewall thickness.
I've ran 275/30 with 20x10 et25 no problem with rolled and little pull

 

 

i would just swap the tires out.. you will be adding an extra 7.5% of milage to your total trip.

for every 50mph it will be adding an additional 4 miles..

every 200 miles is an additional 16

every 10k is an additional 800 miles..

not worth it IMO..

but not only that you are running staggered and oversized.. you are running two different sidewall tires.. a 40 and a 45 series..

its not the proper way to mod a car by throwing on anything that might fit..
