Hi all,
i will like to know if 20” wheels from a 2015 GLK will fit my 2012 E350?
20” ET45 8.5

thanks !

lets see, 17" wheels use /45 tires, 18" use /40, and 19's use /30 or /35... I don't think you can get a skinny enough tire on those to maintain the correct OD, noting too that E350's specify XL tires, and that restricts you to only some sizes.

Sorry
they are 20” ET45

do you drive this car on real world roads where the pavement isn't glassy smooth race track perfect?

digimurda

It’s not for tire size im asking, its about the offset

Left Coast Geek

oh, you're going to run the wheels without tires on them?

then they will probably fit ... of course, the ride might be kinda harsh.


how wide are these rims? stock is either 8x17 or 8.5x18, both ET48, so a ET45 rim will only be about 3mm "in"... of course, if these 20" wheels are 10" wide or something, you're gonna have big issues with scraping hard parts, but if they are 8", the wheels should fit.

european E500's seem to have an optional 20" wheel, front is 245/30R20 on 8.5x20 ET48, while rear is 275/25r20 on 9.5x10 ET48. 2.5 bar front, 2.7 bar rear air pressure.
(thats from https://www.wheel-size.com/size/mercedes/e-class/2012/, no idea how reliable that data is)

oh, do be sure those wheels are meant for M14 lug bolts, AND have a 66.6mm center hole. some Mercedes wheels use larger lugs and/or have a different centering hole. its CRITICAL these match or mounting the wheels would be unsafe.

Hey,

no they are 20” and 8.5 wide all around, and yes ET45

digimurda

same center bore, and thread

ok, they will probably work, for some values of work, with 245/30R20 XL tires. they will ride like skate board wheels on a cobblestone road. 2.5 bar front pressure (37 PSI), 2.7 bar rear (40 PSI). US$300+ per decent tire, and lousy wear life. virtually all the tires I see in that size are summer-only, not suitable for wet weather at all. that tire and wheel size belongs on a Lamborghini, not a 6 cyl E class sedan.

I tried fitting the 20 inch AMG wheels from my W213 onto my W212.
Fronts rubbed against suspension.
20x8 ET43 with 245x35R20.

You might be able to get away with 245x30R20 and ET 45 on the front - with the emphasis on might.

AlloyWheelsDirect list the Brabus version of the W212 having 20x9 ET40 fronts with 245x30R20 and 20x9.5 with 285x25R20. But I guess they would have rolled guards.

I took the 20inch AMG wheels off my W213 and installed 18 inch wheels. I didn't like the harsh ride over normal roads.

So these should work?

Left Coast Geek

bingo. I really don't get this obsession with huge rims and tiny tires.

digimurda

You must really be bored, i never asked for your opinion on my taste.

Left Coast Geek

so its a fashion statement, not for practical use. gotcha. have fun.
