i recently upgraded to 18" rims on my 2001 c240. After the upgrade from the stock rims i noticed over bumps i was hearing a noise coming from the left rear side. turns out that the tire is rubbing against the wheel well on bumps. this is also made extremely worse with extra weight in the car. I put 3 people in the car and noticed the ride height in the rear lower. Is this problem due to the coil springs or the shocks, or do i have to replace both?

What kind of wheels do you have? Did you add spacers? The cheapest route will be to roll the fenders.

How is the tire rub? Is it very hard?

what are the size of wheels/tires?

i put aftermarket wheels that fit the car. I did not put any spacers. fits perfectly fine on both front sides and rear right.

My car rubs the left as well (only when I hit big dips) and I dont even have anything in the trunk. I think everyone has a little tire rib left or right. It's always one side.

Your best bet would be to roll the fenders.

+1 on rolling fenders

What are the offsets of the wheels? We can't help you unless you provide more info. Just because a wheel has the correct bolt pattern, doesn't mean the offset (how far in/out the wheel is) is correct!

A ghetto way to check what you're hitting is to put some ghetto cheap (washable) paint along the sides of your wheel, bump it a few times, then see where the paint smeared. Then decide what you would like to do to rectify the problem.

Ya man, if you provide wheel size then we can help you better. rubbing on 18's that's pretty unique. Like I said I have 19" and I hardly rub. Only when there's 4 peeps and I hit big dips.

This might help if you don't know your tire size.

as said above

1. what is the spec of the rim. width and offset

2. what is the spec of the tires. tire size.

without it no one can answer your question.

I have custom rims which are rubbing in one place inside wheel arch when I turn the wheel or brake the tires are C320 tires 225/40 zr18 92y

With some thin spacers I think I still have the wrong size spacers as they rub inside the alloy rim and bottom front of the wheel arch any ideas thanks

I have an 01 C240 as well with 18" on 225/40/r18 and I don't get any rub at all, did you do anything to the suspension at all?

They were rubbing inside the alloys also so pep boys but some spacers now I get rubbing at the front wheel arch will post a picture sun thanks in advance

What size and offset is your wheels

Also are you lowered?

roll your guards and grind the little tab that comes around from the back. Didn't work for me but you should be sweet with 18's

Hi I'm attached pictures and measurement how do you roll the guards and grind the tabs ? Sorry to sound dumb just bought the car

Lol um I don't see any pictures FYI

finally some pics thxs

those arent wheel specs. do you not know what the sizes are? like are they 18x8.5? the information should be on the inside of the wheel. the offset should also be on the rear, its should say et with a number like et 35 or something like that. Since they are custom wheels I would hope you would know the specs of the wheels, or did you just pick them up from someone. also spacers go by mm usually so the spacers might be 10mm or 5mm.

in the last pic of your car it looks like you're fronts and rears should be switched but I cant tell since I dont know the specs of the wheels you have on there. But it looks like you're fronts offset is pretty low since you have so much wheel poke.

Hi thanks for your time in advance I just bought the car and got the brakes redone all around an the garage said the spacers weren't wide enough because they were rubbing on the inside of the alloy I think they are still rubbing and the front inside wheel arch the same place I will have to take one wheel off to try to get the numbers as you can tell I have no clue about offset etc so appreciate your patience where do I need to measure ? And will do love the car driving me crazy

You might have to sell those wheels and get different ones. But looking at the pics, it looks like you should clear the brakes since you don't have the larger brakes. But if you need larger spacers its going to make the front stick out too much and make it look bad. You'd have to really roll and pull the fender to get the wheels back under the fender. Make sure the wheel is rubbing the caliper and not the lug bolts being too long and grinding the braking system.

Hi I've measured the spacers 6mm on the front and the wheels are rubbing on the brake caliper grinding what is the maxim spacers I can put without replacing the studs wheel nuts and keep the profile. I will take one off to get the offset but wanted to order some larger spacer for the front as an alternative let me know what you think thanks

Hi yes it's grinding on the calipers I saw the marks on the inside of the alloys

Hi what size spacer do you suggest ? Will a 5/16 which is a couple of mm make a difference .

spacers come in mm you need to look in mm not inches... measure your spacer and convert it to mm thats going to be your best solution to find what spacer you need. most spacers come in 3,5,8,10,12,15,20,25mm... they make custom ones but you'll have to look around. H&R make spacers for our cars and when looking for a spacer you need to makes sure they are hubcentric and make sure you buy new lug bolts to accommodate the new spacer

Hi again the 6mm are rubbing slightly on the front if I goto 8mm do I need to goto larger bolts nuts which are oem at the moment or should I just goto 10mm on the front for the spacers ? The wheels are the same front and rear offset so don't think switching will help

Make sure the poem bolts aren't too long. They should do 6 full rotations from beginning of threading to it being tightened. If you have too much them your bolts are rubbing.

If you go with 8 you won't need new bolts but if you go with 10mm you will.

Can you take a front view of the car from straight on to see how much the wheels poke out from the frame. Because looking at the side view it looks like quite a bit.
