'24 X1 28i cames with 225/55/18 102H all-season tires. there are basically no good summer tire options for that size here in the US. also don't want to buy new wheels

is it okay to replace them with 235/50/18 101Y summer tires?(such as the Michelin Pilost Sport 4S)

or will that trigger fault codes... or mess up the xDrive or even ABS/DSC system? according to online tire size calculator/comparison tools, the difference will be less than 1mph at 60mph
