I am looking to buy some rims for my 4 door 98 oldsmobile cutlass. I really dont know what to look for since this is my first time purchasing rims. Whats the biggest size rims that will fit on my vehicle without lifting? Would the tires Im rolling on right now be fine or would it be better to get tires also? Im looking to buy locally but I want some prices online so I can compare so any good sites?? Thanks for all of the help
