I think is too much the garage pull this is my new tire

 

whoa!! You should be good at 40-44psi for highway driving under 140mph though I would consult tirerack or the tire manufacturer first

 

Its a wee bit high. 45 should be good. 37 -40 resulted in some bent rims for me earlier in the year so I stay above 40 with no problems

 

40 cold ? I think the tire take 4-5 psi when is hot

 

Cold I use 48 front 40 rear. Results in even tire wear and close to neutral handling. The tires are Conti 5P's if that matters.

 

I just follow the AMG-specific tire pressures behind the gas door lid - 42psi cold for normal driving and loads.

It's annoying that it has incorrect information on the drivers door sill. I've never seen any other car with wrong information on the door sill.

 

I do 43 with my aftermarket low-profile Michelins.

 

Holy cow, way too high. What does the placard on the inside of the fuel filler door specify?

 

I'm in So Cal and go with 44 all around cold. With normal driving, it usually goes up to 48 fronts and 47 rears in city traffic. I'm on the Conti SportContact 5s.

 

I run 38 psi cold, I find it to be the sweet spot for comfort and performance. OEM 19" wheels with michelin A/S 3 plus tires.
