I desparately want to upsize, because I'm sick and tired of traction issues!!

.................235/18's in front and 275's rear

Ted: isn't 275 for the rear would be too tight?

Is it the same having 275 on 18in wheel and 275 on 19in wheel?

I just ordered 18x9's from tire rack. When getting the tire sizes, I wanted to get 265's on the back, but they said their testing notes showed that there would be some rubbing in that size on the CLK55. Even though the car comes with rolled fenders from the factory. Plus in the forums a lot of other people complained over time that the larger rear tires rubbed when there were passengers in the back. So i ended up with the blessed 255's.

Ask this to Luke. He works for Tire Rack and knows these cars. I believe 265's don't rub on CLK55 but do on CLK430. Also depends on the mfg of the tire.

My 19x10 265 in the rear don't rub.

it Look flush to fender. my 265-30-19 in rear too but it doesn't look flush like your..I like it flush to fender..

Bruce,

You obviously dropped your car a lot, so did you do any mods to the fender? Yours didnt come factory rolled, so i am assuming you did something, and that will make your situation different than the CLK55 situation.

I would like to know from experience, not speculation if the 265x18's fit on someones factory CLK55, because there is more of a tire selection in that size. I really dont want to deal with rubbing noise when i get someone in the back. I had to cut the fender lips out of my last car because of this.

Bruce, additional question- Does your decklid spoiler attach to the underside of your trunk lid? And where did you get the upper spoiler?

Thanks

..........It depends on the tire manufacturer and whether or not you lowered your car. I have 265/45/18's with 12mm spacer on 18x8.5 rims without rubbing except minimally when I have two passengers in the back seat which I hardly do. My tires are S-03's. However, I had the same rims and same size tires but wider spacers(15mm) with Toyo T1-S tires without rubbing even with two passengers in the back. In addition my car is lowered with Kleemann suspension. Therefore, in a non lowered CLK, you should be able to run 275's in TOYO tires without spacers with no rubbing. S-03's are the widest tires and it seems Toyo tires are the narrowest.

Ted,

Do you mean 265/35-18 ? A 45 series would throw off your speedometer badly, and I couldnt find that tire size for sale.

Also, is your car a CLK55 or 430. The CLK55 is already an inch lower from what I understand. So the info would apply depending on how much you lowered your car.

Also, did your previous rubs occur on the inside of the tire or the outside? Why the spacers ?

Thanks,

Carl

A key ingredient to figuring what wheel/tire will fit is knowing the offset of the factory wheels as well as the aftermarket ones in question. If you know the offsets, wheel width, and tire size you can use a ruler and a plumb line to make careful measurements and then calculate what will fit. I've done it on a few cars and it worked out within about .125" of calculated values. All the measuring and calculating takes a while though, so it might be easier to just find someone with exactly the same setup - wheels, tires, springs, etc. -- as you want to run.

amgpowered: Can you order a car with factory rolled fender? Did they just cut the inner fender and put some rubber?

I have a 19x8.5F ET 35 and 19x9.5R ET 35.
I have bought a set of Dunlop tires 235/35/19 and 265/30/19 and some spacers just in case if I need them.

I have a CLK 430 and will be equipped with H&R spring and Koni shock.

Any idea if this is going to work without any rubbing or I have to do some work.


Thanks,

................sorry I run 235/40/18 in front and 265/35/18 in the rear


Ted

Just to make one thing clear, I do not work for Tire Rack.

You will have no problem with your choice, we at Kleemann run exact the same sizes and no fender trim is needed, you can use a 6-8 mm spacer rear without trouble.

Thanks Lucas.

And for the guy that works at the Tire rack, I think he meant Luke



Solihin

yes, i meant Luke. Sorry about the mis-type

I have the following setup and NO RUBBING! If there's no one seated at the rear.

FRONT: 235/40 ZR18 Michelins Sport on 18x8.5 inch wheels
REAR: 265/35 ZR18 Michelins Sport on 18x9.5 inch wheels

I have also NOT rolled my fenders either.

I personally think the the rubbing i get ( only when person is seated at the back ) is due to the fact that my shock absorbers are standard. I have only replaced my springs with Eibach springs.

It doesen't help much that most of you post wheel sizes, the offset is just as important.

WRITE OFFSET ......... there is a huge differense in a 9,5x18 ET 25
or an ET 40.

I use 245 for front and 265 back and just some rubbing when i go out bumps and that's it...you can use a heat gun to melt the plastic (near) the fuel tank (NOT THE FUEL TANK) the rubbing will be gone.

Lucas, if you got the wrong offset, let say its bigger (supposedly you have to get 30mm offset, but you have 30mm offset wheels), shouldn't a 5mm spacer fix everything?


VAN_CLK: where did you feel the rubbing from? front or rear?


Thanks,


Solihin

Look at your post again - I don't get it ?????

The higher the offset is, the more the wheels will go in.

The lower the offset is, the more they will go out.

So ET 25 is more out ( more problems with rubbing ) than 35.

The rubbing is from the rear near the gas tank....

I have a 265-30-19 Rear with a 38 offset wheel. but its rubbing with passenger in the back seat, what if I add a H&R 10mm spacer will this solve the problem?.....and I have about 3/4 of an inch from the fender.......Thanks...

I dont think this is too low, I just need to replace my shocks. Do you guys agree? Will the rubbing go away if I replace with stiffer shocks?
