Hi, My 328i(E36) currently is bone stock with the 15" 10 spoke OEM wheels with 205/60/15 Michelin MXV4 allseason tires fitted on. My question is, what if i get a set of new summer tires while using the exisiting rim, making the sidewall more low profile by getting tires with 50-55mm sidewall? Would there be a decrease/increase in wheel space or ride height? Also would it be a good idea to do this or it would be better off to keep it with the 60mm sidewall width?
