I have 285/9.5/18's on all four's, will they rub after I lower and align it? (Eibach Pro-Kit Coupe)

After you lower it? Of course it will, on big nasty speed bumps and driveways... I bet you could make it rub without lowering it if you try! <chuckle>

Seriously, I lowered mine with the 1-inch Steeda springs on stock tires and wheels and there are a few places I rub, but not many. Obviously, you have to be careful...

I think he is talking about the tires rubbing since they are so wide. I would like to know as well

the back will be fine not sure about the let front

285/9.5? Do you mean 285/40? You will not have a problem with the back, that is what I have on mine. However, some have already posted that after putting 285/40's on the front and lowering the car that the tires rub when you turn them almost all of the way.

I have 255/50-17's up front and my car is not lowered, and mine rubs slightly if the steering wheel is turned full-lock left or right. So, I'm guessin 285's on a lowered car will rub too.

Hey guys, sorry I guess I should have made myself clear.

I already have the 285/40/18 tires on my 18/9.5 wheels, and yes they do rub if I turn the wheel already...

Now for my question I meant after I lower the front end, will the tires rub on the upper fender?

Thanks...

adrenalin

maybe it is the offset you guys are running. I have 255/45R18 mounted on the front and they don't rub at all, even when the wheel is turn as far as it will go. Car is also lowered.

So to answer you question, the tires may or may not rub depending on the offset of your rims.

The 255/45-18 tire is slightly shorter than the stock tire... that certainly helps avoid any rubbing too.

Here is a handy-dandy chart for tires sizes:

Actually, the tire I have is very close to the diameter of the stock tire. Look at that chart again and remember, I have 18" rims. My front tires are only .14mm smaller than the stock tire diameter. This is the reason I chose the tires I went with. Even though they are wider (255's front and 285's rear) they are extremely clost to having the same diameter as the stock tire. 0.14mm is not that much of a difference.You're talking the thickness of a human hair.

The wheel offset is the key. What you hope is that the wheel manufacturer you have decided to go with has done their homework. Roush has 18x10s on the front of their lowered cars.

SixtySix

Wow, we have the same tires and I've noticed no rubbing

Oh, but you do have the 9in rims though, that must be the difference. I'm still running the stock bullits.

adrenalin

Good point. My rims in the front are only 8" wide. However, I still think it comes down to offset. Like Randy said, Roush has 18x10's all around. If I knew that was possible I would have done the same. :bang:

don_w

I don't want to get into a "hair" splitting contest (pun intended), but 255/45-18's are 0.14 inch (not mm) shorter than the stock 235/55-17. But 0.14" is about 1/8-inch, so basically it is a negligible difference and about the same as stock as you said (but definitely bigger than a hair.. lol).

And yes Tony, I run 17x9s up front, so that may have something to do with it.

Dan

If by slightly you mean 0.4%, then yes

adrenalin

Ya, my mistake. I'd hate to bump into someone with 1/8" thick hair

It all depends on the offset of the rim. Saleen 05's are running 275's in all 4 corners. I have 255's up front and 285's in rear. I have not once rubbed and have accidentaly slammed some speed bumps to the bottoming out point and there are no signs of fender well inside rub.
