CLS 6.3

Im tired of the 20" wheels that came with my 2012 cls 550
With the ****ty roads we have 20" is not an option for a daily driver

I just bought a set of 19",, 8.5" front and 9.5" rear and im wondering what is the maximum rubber that i can fit with no rubbing issues
Currently considering the
245/40/19 front 275/35/19 rear
Will this set up fit with rubbing,,if not what do you guys recommend?

Need to know your wheel offsets in order to answer your question.

CLS 6.3

Wheels finally arrived

And here is the offset

Rear 19x9.5 offset 35
Front 19x8.5 offset 35

Would this setup fit
245/40/19 front
275/35/19 rear

Yes this set up will fit, however due to higher front diameter than stock with stock front offset, 5mm to 10mm front spacers are advised. For the rear, assuming you're not lowered, you can use even 285/35-19.

I appreciate your fast response,,and yes im not lowered
just to be sure,,if i run the set up without the spacers there may be a chance of rubbing in the front?

245/40-19 tire is about 26.7" diameter (vs. stock's 26") combined with stock like 35mm front offset will be very close to airmatic's rubber boot. You should be OK, but just in case you're not, 5mm or 10mm hub centric spacers (absolutely safe to use) with longer bolts will do the job.

threeMBs covered it.


I know it's all personal preference, who likes the flush look, etc, etc but I wished you had gone with an offset for the rear in the 40-50 range as it would have given you more options for a stock or wider tire for the rear. Also, if profile is the same ratio and all else equal, a wider tire would also give you a slightly larger side wall for a hair extra cushion to help with those potholes.


That rear offset makes matching a wide front and rear staggered set challenging due to rub with the rear lip, trying to match all 4 tires heights, etc.


Let us know what you decide and how it turns out.

Thank you again for your clarification your info are very helpful and i will update you guys of how everything turns out,,the car still at the shop recovering from the **** the 20" wheels has done to it.

CLS 6.3

I appreciate all the help and support you guys shown through the process and here is how everything turned out.

I went with a set of hankook tires with no spacers in front to try it out,,I experienced no rubbing,,I can feel the ride quality got better over bumps not as stiff as oem
245/40/19 front
285/35/19 rear
I have included pics of clearance of front tires and how it looks with its new shoes

Are you selling your 20" rims? If so, send some pics.

Hi, why are you not sticking to original approved sizes?
