I currently have 20' HRE 943R's on my CLS550

Front set up is 20x9 (+31 offset) with 245-35-20 tires
Rear set up is 20x11 (+25 offset) with 275-30-20 tires

I am thinking of changing out the tires both front and rear tires for couple of reasons. The tires size I want to use are:
Front 255-35-20
Rear 295-30-20

I work and live in greater LA area so there are lots of pot holes and bumps so I want to give my front wheels as much protection as possible. By changing the fronts to 255-35-20, because of the diameter and width of the tires, I am pretty sure it will give better protect against pot holes and bumps for my front wheels. I am also thinking of changing out the rear tires to because my current tires (275-30-20) give stretched look on my rear which I really don't like and also the guys who put my tires on told me that its not safe to drive around with stretched tires because there are not enough side wall sealing the air with the outer edge of the wheels so on a hard turn, it my leak air.

Both 255-35-20 and 295-30-20's are 27 inches in diameter which will make the front and rear even. My current setup 245-35-20 is 26.8 inches and 275-30-20 is 26.5 inches so there aren't much difference in diameter other than the tires will be little wider and little taller.

My car is currently dropped with Links which give me just tad less than 2 finger gap both in front and rear. I can always adjust up if needed.

Anyone have any idea if the new tires setup will work? Anyone currently running 255-35-20's in the front and 295-30-20's in the rear?

Any input will be greatly appreciate it.

Thanks

295-25-20 Rear IMO!

Hankook V12 has a great deal going on tires i never tired them but alot forum members have good review

I like low profile side wall (not so tall in 30-25) i have pzero nice,grip,wet,dry but they wear out fast especially since the cls is lower i have neg camber issues. my tire set up is 255-30-20/ 295-25-20

 

If you run 35/30's on the CLS the speedometer will be off over 3%, which is not good. I ran 20's with the 255/30/20F 295/25/20 R and the ride was noticeably rough.

Going to 19's....

 

I don't mind speedometer being off a little. Also on most every car out there, speedometers show higher speed than the actual speed that car is traveling at.

 

255/30/20 n 305/25/20 wil set it off nice........................handel nicer n even height all around....

 

I would go with these, only tires in size your looking for that comes with an 50K warrenty http://www.conti-online.com/generato...n,tabNr=1.html

 

You'll want to go with 255/30/20 in the front and 305/25/20 in the rear. It will work out just fine. 275 is way too narrow in the rear for an 11" wheel.

Ben always crying. Lol.
