E550C tire pressure
Hi Guys,
I bought my first mercedes 2 months ago. I don't know much about cars, but I think I got the nicest looking car on the road. Having said that, when I picked up my car, my tires had pressure of 52 psi and looked like balloons, so I went to the dealership and they deflated them a little. The side of my door says front must be 35 and rear 44. Right now, they are 37, 42 on the left and 36, 41 on the right. I just can't seem to be able to make the pressure exactly 35 and 44 because the pressure monitor doesn't display the actual pressure unless I start driving the car. Should I be concerned? According to pirelli's specs, psi is 50 for these tires. I drove the car for 2000 miles with 33, 36 with no problems then I realized it should have been different. I got amg wheels.
Thanks

there are a couple things to think about ... gas mileage and wear patterns. i find i can get one or two points of mpg better when my tires are properly inflated (36/42 when warm). if your tires are wearing too much in the middle of the tread, they are overinflated. if they are wearing too much on the edges, then they are under-inflated.
also, there are considerations of speed and braking. the reason the front tires are lower is to aid in the braking process and handle the weight distribution over the front tires. if your tires are properly inflated, i.e., not under-inflated, you can accelerate better. if your tires are over-inflated, you need more braking distance as there isn't as much friction on the road.
i'm not an expert - but i have had a lot of cars and i have spent a good deal of time thinking through this.

i keep mine around 36 in the front and 41 in the back when warm. it's important to consider warm tire pressure versus cold tire pressure. your tire monitor system will update within minutes. you can get a pressure gauge if you can't quite get it right, but one psi won't make a difference. if you have heavy loads you can increase the tire pressure, but follow the specs on the door. i think anything below 33 cold in the front (or 36 warm) and 36 cold in the back (40 warm) is too low, and anything above 38 in the front or 44 in the back is too high.
