can anyone help??? i need to know if i can fit 20x11 in the rear of my cl55???

;you can, 305/25/20's

Will I have rubbing or have anythin to worry about? Thanks for replying man, I hav a good deal on a set of Avus wheels and wanted to know if they would be ok.

more likely you would, maybe go down to 295/25 or 285/30's , and maybe roll your fenders a bit to get rid of them... if u don't hit any bumps you should be fine or just raise the car in places that may be bumpy...
post some pics of the wheels...

Thanks alot , I'll post pics soon

It will rub (with the best offset that is) on just about any dips. 11" wide rim will actually measured 12" from one side to the other. And 12" = 304.8 mm

If you run 305 (mm), it will be some what even although in my opinion, the best combo for 11" wheels would be 315 tires. 285 or 295 will stress the tires a bit (look kinda "donk" in my opinion but some might like it) not to mention you will scratch your rims much more easier since you have no protection although 285 helps a little with the rubbing issue.

If you have aggressive offset and not lower your car, it might be ok but your wheels will stick out too much.

I have 10" with 275 and "medium" lower and it already rub (left rear) from time to time (on medium to big dips). Let us know how it goes and post pics if you could.

As I believe the only person on the board running 305s, I'll explain what I have learned. When I first put them on two years ago, it was after the car was lowered 1.5 inches, and it rubbed pretty good on freeway undulations, maybe once every 10 miles or so. Raising the car on the freeway (where it naturally lowers itself) seemed to have helped. And Lionking30 has it right, just hit the raise button as you go into a shopping center or any other area with big dips.

After the initial rubbing, for whatever reason it happened less and less. Now, on the third set of tires, it rarely rubs. The rubbing never caused any noticeable damage to the tires. Now on freeways it hardly ever rubs anymore, only in the worst of situations (such as a metal plate over a construction pit) and only the worst of dips and parking lot gutters. From my own personal experience having the 10.5 inch 305 setup running strong for over 30000+ miles, I would say SLCL overstated the rubbing.

My rims are 10.5 inches, and yes the 305s are just over 1 foot wide. They still fit up inside the fender but this seems to be the upper limit. I don't think 315s would be possible. On your 11 inch wheels, though, I would stay away from 285 or 295, as SLCL suggested. If they work for you, you can finally be the second person I know with 305s on the 215 body CL.




(see sig for more pictures)

To clarify, I am not suggesting 285/295 with 11" rim wide (I have 275 on 10" and the tire seems to be a tag too small for the rim). I would think 315 would be best fit for 11" rim but it would not fit on the CL without modifications.

As you stated yourself, you have 10.5. Adding an extra 0.5 inch would be totally another story.

The is a piece of medal on the inside rear wheel well where the body connects to the rear bumper (on both LR and RR). You can put your fingers and and feel it. Why did Mercedes design such a bad thing (as it was not on my SL)?

With rubbing issue, I seem to have it on the left rear (for just about any mercedes I have if I run wider tire or lower too much). What side did your rub?

BTW, did you manage to sell your car Patentmat? Very nice interior I must say. What are you getting now?

I think we can all agree the 305/25's look very nice.. however, would you loose in comfort in the ride suffers greatly. You probalby feel every little bump in the road..

I would disagree that the ride suffers "greatly". I've driven a stock CL600 back to back with my car and it was not like mine was some slammed civic bouncing and bucking as it drives along. SLCL, interestingly, just like you it was the left side that rubbed more.

I had offers come in for the car up to $24000, and it had 88K on the clock, but I just couldn't do it. So the car remains all mine for now : )

any thoughts of fitting 305s on w220 body s65?

The 55 has better "forgiveness" for wider tires than the 65. If it doesn't do on a 55, it will not likely fit on 65. I don't have the W220 but I think they have same specs as their counterpart W215.

,

Have 285/30/20's on S55 and had 275/35/20's before, and they both rub on bumps, like a medium to big bump, fine on smaller ones. nothing too bad though.
and on my CL have 275/35/20's and it does rub on tiny bumps, may go to 285/30/20's next time around

It could be the height of the tire that plays a factor. Lionking you mentioned going from a 275/35 to a 285/30. That would actually make the overall wheel smaller - - it is possible it might rub less. My 305/25 is even shorter, and actually quite close to stock size.

I just went from a 275/30/20 on a 10" wheels that NEVER hit..... to new wheels and went to a 10.5 with a 285/30/20 and it will hit on a dip. Its not real bad but I am not use to hearing that. I don't think I could ever go to a 25 series tire. I live in the Mid-west and the roads here have their share of pot holes ! In fact, I bent the Lowenharts I had on the front with a 35 series tire. It was a expensive repair ! If you bend the wheel the tires goes flat in a hurry and trashes the tire by the time you can get to the side of the road ! Anybody relate to this ?

I can relate. Yes that dents are the downside, to go really wide, like my 305s, you need to drop down to a 25 series. I have bent my wheels probably six times over two years. I have a place in Sacramento I take them to that charges $140 per fix, and I have been happy with that. The first time I did it, yeah I ruined the tire, but since then the tire has always been alright. This is on mostly California Bay Area roads.

I have a 2005 CL55
19x8.5/Front, 19x9.5/Rear
Offset: 44/Front, 46/Rear

I want to put 20" wheels will the same offset be fine N does the width of the wheel matter?

Just for an fyi for us CL owners. Yes you can fit a 11" wheel in the back BUT it will rub on the rubber boot dust protector for the rear strut. The max you can run is a 10.5" wide rear without rubbing or pulling fenders.

Same for me, left side rubbs but its only on long dips o highway.
285/30 on 20 inch, 10"; 2005 CL600

Hey, what are your Offsets?

^^He doesn't know...

R.K.

I tried 305's. They stuck out past the fender by abound 1/2 inch and also hit the rear strut. Not sure how 305's would fit without rubbing unless you really flared the rear fenders. The last thing you ever want is a tire that rubs against any part of the body at any time. You are asking for a blowout.

wow offset must be really high to do this. I'm running 285 and rub
