I’ve just recently changed all 4 alloys and tyres on my e350 2011 cabriolet due to a cracked alloy. My problem now is that the drive isn’t smooth as before now the drive sounds loud and rumbles with the new tyres on the vehicle. The car now pulls slightly and the steering feels a lot more heavier. All 4 tyres have decent thread. My recent tyres were rear 255/35/18 front 235/40/18 and what I have put on the car now rear 265/35/18 front 245/40/18 can anyone tell me why am I experiencing this issue please tia
