Tire pressures for 12 CLS63?

ajag · 11-29-2011, 05:06 PM

Ok, inside of driver door recommendation is 51 F/R, I read manual, searched forums and googled it, no other info I can find. This seems kind of high, is this for a fully loaded car or one driver? What are other people running pressure on the OEM tires?

I think its 51 lbs when you have three passengers with luggage and want to travel up to 186 mph.

Under 150 mph you can inflate with 38-40 lbs of cold pressure.
If you want a softer ride try 34-36 lbs of cold pressure.
You can find this decal by the gas cap.

I run mine at 46 - 48 cold. That's how it came from the dealer, and I've kept it there from day 1. The ride and handling are superb.

Anything over 40 is too much... not optimal for treadwear imho as well as you will wear out the centers.

Tom is right, 38-40 on the stock 19's is spot on. Remember the door cap is showing cold temps- as your tires warm up your psi will jump 3-4 psi depending on the temps outside and how you drive.

Sounds good, I'll go w/ 40 F and 38 R and see how it feels, dealer set it at 36 F/R.

so we're all in agreement that the front's are higher psi than the rear??

I cant remember what I ran on the stockers but it wasnt more in the front. I did check the inside of the gas cap and its weird that the front is more. Now that I run aftermarket Im good with 38-40 all the way around.

I have stock 19" wheels and tyres. I am using 31lbs back and front. Much better handling and ride all over. Anything over 34lbs is too bumpy.
