I currently have 225/45/R17 all around on my car, but I recently got a refund because the front two tires were seperating due to manufacturing defects. Is there any way that I could fit a 235 or possibly a 245 on the rear to get more rubber on the back wheels? the wheels measurements are 17 x 8 ET37. Thanks

Are you really running that much HP that you need more rubber back there?

Not sure your wheel is wide enough for 245s on an 8-inch rim. I've got 245/40-17, but on an 8.5 inch rim....and my rear fenders are rolled. Check with Luke at TR and he may offer some additional insight.

Well, you wouldn't want a 245/45 ...it'll be too tall. A 245mm tire fits fine on an 8" rim btw. 17" EvoII rims from SLs and E500 Limiteds run 245s on a 8.25" rim from the factory...and a few 500E guys have put 265/40s on them rims with no problems, but our rear fenders are pulled out about 2" over a stock W124 sedan. Offset is 34mm on them 8.25" rims also.

You'd def. need a fender roll and probably a different offset rim. Pretty sure it'll rub somewhere on your lowered car with no further modifications....but what do I know sitting 1500 miles away ! LOL

Chappy, your wagon has a 245/40/17 rears on 8.5" rims? My Cabby needs to roll on some wider rubber and that is very encouraging to me to read ....not that it needs it, but optically it does !

Chappy

8.5 inch is what I have in the rear. I took them off my CLK55 - staggered setup (7.5 X 17 front, 8.5 X 17 rear).

Jim's500E

I saw that and corrected myself....thanks.

What are the offsets of those rims if you remember? Gotta get some now.

Chappy

Going by memory here....IIRC, the offsets are ET30 and ET37. TR is sold out of most of these in 17 and 18 sizes.

Jim's500E

But I'm the wheel *****...I'll find a set ! LOL (4 sets for the 500E alone, I have issues, I know)

Thanks Chappy...any chance for a pic of that set-up on the wagon? I'm imagining it looks stellar.

Chappy

There are several before/after pics on this thread...

FWIW, I think there is a set or two of Mono IIs in 17 being advertised in the Classified Section. Lensolo may have a set plus another member as well.

Good luck!

haha! I got lost in that linkthere for a sec

did you ever put on the amg badge?

Chappy

Obtained this one, but haven't installed yet....

I hate to thread jack, but since this is about 245's and all I figured I'd throw in my question too.

My rear's are 245/45/17's on an 8.5" ET 40. Its sticking out already, and rubs when there are people in the car.

I just bought lowering springs, and am in the process of buying stiffer shocks. What are my options, what can be done?

Im in need of desperate help...lol

Jim's500E

It seems to me that the rear set-up is too tall in the tire aspect ratio and/or the rim is too wide for your car. 8.5 wide rims usually fit W124 sedans but its the offset on those that mean everything....and other folks here run that size tire on 17s though. Lowering springs doesn't sound like a good idea...does it if it rubs now? It'll rub more with lowering springs. Of course, a body shop could pull out those rear arches but that's $$$.

xudeck

Well I guess, then my only option is to sell those lovely Mono's and get different ones. Whats the magical Offset no. that I should be looking for, front and back ? My fronts are 35 and they seem to be doing just fine, but then again it's not lowered as of yet.

ohlord

35,confirm at the sponsor tirerack they will tell you what will fit.
for heights rpms per mile offsets etc.

Where does it rub? inside of outer fender in front of the wheel or the suspension or shock behind the wheel? Maybe a 235/40 tire will work out?....35 mm seems to be the magic offset. A 5mm spacer wouldn't help in your case I feel...would make it worse.

Pretty sure you could sell the rims and get the correct ones for almost a wash...if they are nice shape, etc.

ZorroAMG

Holy SIDEWALL batman.

I run 215 40 18 and am VERY close to rubbing.

245's on a lowered non 500E500? Crazytalk.

xudeck

Fronts are ET 35 and the rears are ET 30 !! And the rear is the problem, not the front.

17x7.5 ET 35 225/45/17
17x8.5 ET 30 245/45/17

It rubs on the inside of the outer fender, at the sharp edge. I actually have lost a tire because of that rubbing.

If the rear's cant be rectified, they will be on sale by tonight. Thing is, not enough of them are selling to buy back another set.
