Has anyone tried sizes 245/45 r17 or 235/50 r17 on their car? Is their any rubbing/problems with fitment? Right now the dimensions on my car are 235/45/ r17 and I would like a little more sidewall - more comfortable driving experience.

I usually follow the instructions that are in the fuel cap. Last time I drove with 3 passengers (plus me - 4) and full trunk. I adjusted the pressure for all the tires - 2.9 bars rear and 2.6 front. It was fairly good while driving, but when I drove the car with only me it was an agony. It believe lowering the pressure can do something but also fuel consumption. Also, my driveway has a nasty ridge that people usually scrape and my car is dangerously close to it so i'd also like it to be a little taller. Even by a few millimeters. The car is e350 cdi e coupe - year 2009 with amg sport package

I have seen going down from 18 inch to 17 inch wheels because that gives you more sidewall for a smoother ride.

Just moving to a taller and wider tire for more sidewalk with the same wheel will throw off your speedometer.

Not sure if a 16 inch wheel is available and if it will clear the brakes but going to a 235/50R16 will give you a softer ride, won’t rub, and will keep your speedometer reading true.

Then i guess id do taller and lower psi?
or just get softer shox. hard to find softer though.
I used to revalve the shox but at some point years ago the changed the design and made it too difficult to take apart.

using tire size comparion the 235/60 R16 says the diameter is a lot bigger than the 235/45 R17, which is recommended. I think the recommended percentage of difference is 4%... Might be wrong
