Tire size and offesets for 20" rims in CLS
If anybody can help me am suffering from the deformation from the inner wall of the front tyre for my cls with 20in rims. The tyres are of 245/30/20 size and the rear ones are 285/35/20.... am not sure whether the fault is from the tyres or from the rims. This is the second time that am changing the rims. I bought at last original mercedes used rims of 20". I am changing the tyres around every 2 month maximum. Now they run less than 3000 km and the internal wall damage started to appear. I tried both altenzo and a company called carrera tyres where both are of chinese origin. I am worried to change for an expensive brand like contenintal and again the same would happen! Can any body advise me what would be the actual problem. I am using it normally on highways where usually i use cruise control at 140 km/hr. I live in dubai where the temperature is elevated normally around 45 C. Please advise

It is not rubbing. I asked today they told me from tyre, but i have a doubt still since they just want to sell. I cant use 245 35 20 tyres since they cant fit due to the suspension arm.

On front I have 245/35-20 on 8.5" wide et20 (yes 20mm) wheel - tire/wheel combo looks to be fender flash. Contrary to my previous statement that 255/35-20 will not fit the front, now after seeing how much room is still there after fitting 245/35-20, now I think that you might be OK with 255/35-20 upfront, but I think wheel's width and offset will need to be just right.
On rear I still have 275/30-20 on 10" wide et30 wheel - tire/wheel combo also looks to be fender flash. Later in the week, I'll put 285/30-20 on 9.5" wide et28 wheel and will post picture of that too.

Im taking my chances with 245/35/20 9" 30et and 285/30/20 10.5 30et. rear will be aggressive, front should be perfect with 25et on a 9" but we c. its very very hard to find a wheel I like with perfect offsets, without spending big $$ on forged wheels

ET 26 is front and rear offset I believe. Unbelievably I cannot find any pictures on the old car - which has gone to god sadly. Have the Renntech lowering module which made it look nice, will be fitting to the new car.
Old car was black and the new one is silver.... am planning to repaint for the new steed, any suggestions on best color for these rims on a silver car?
