just bought a set of W210 sport wheels, 16X71/2 ET41.
couple of questions. will they fit without modifications? what size tire is correct? what tire sould i buy? the car is a '94 E320 sedan.
just redid the suspension and brakes, bilstien sport shocks and struts, stock springs and pads new rotors and pads all around, new diff mounts and steering damper, etc.
car will be my daily driver and will receive no other mods. just normal daily driving, no agressive hot roddin'. i do like to drive in the twisties with a little "verve" on occasion. all comments welcome. regards, michael

Should fit just fine. Original tires (non-Sportline) were 195/65/15 or 24.98" in diameter. 205/55/16 would be 24.88" in diameter, or .4% under, but you could go wider if you wish, should stay within 3 percent of original diameter.

215/55 is 25.31" in diameter or 1.3% over. 225/50 should work too. Tire diameter formula is width in mm (215) divided by 25.4, times aspect ratio (.55) doubled (1.1), plus wheel diameter (16). Sponsor Home - Discount Tire Direct is a wealth of information.

320E '93 Tires

Should fit just fine. Original tires (non-Sportline) were 195/65/15 or 24.98" in diameter. 205/55/16 would be 24.88" in diameter, or .4% under, but you could go wider if you wish, should stay within 3 percent of original diameter.
Is it OK then to install 215/65/R15 on the original MB 8 hole wheel?

Would really appreciate expert advise on if 215/65 ires would present problem on other functions (Brakes, steering) ?

Tks.

215/65/R15 would be too wide, it will rub on the front fender where it joint the bumper. I had 205/65/R15 on and it occasionally rub on the right side had to put washers on the fender and bumper wrap around. 205/60/R15 wouldn't had problem at all.

I decided to go wide when i changed my tires few years back running 205/60/15.
They are perfect fit but i did see 1-2 mpg drop in my mileage.

And FWIW I went back to OEM after wearing out a set of 205/60s, no particular reason other than the spare cover wouldn't close tight. Talk about factory tolerance!

- To put wider tires you need lower ET, ET41 is bit on the higher side, factory wheels that came with ET41 used 205/60/15 from what I remember.
- For rim width of 7 1/2 ideal Tyre width would be >= 215, based on your requirement ET34/37 would have worked.
- Additionally you need strut travel limiter + fender modification, there are many threads with this info here.

While searching for Monoblocks I just now bumped into a set of 16" R170 SLK wheels with 16x7 ET 37 (205/55-16) in the front and 16x8 ET 30 (225/50-16) in the back.

Would those work in my Wagon? Kind of thinkin the fronts have too much ET and the rear too little... Comments, anybody?
