I'm want to install Michelin 4S on my 718 Base but I'm concerned about them potentially avoiding manufacturer's warranty and CPO warranty since they arent n spec.
Hey thanks for the reply. I have 18 inch wheels. I agree it shouldn't void any warranty I just dont want to give them any reason to.What size wheels? At least in the 20" version they do make N spec PS4S tires.
Also, using a non-N spec tire will not void your warranty.
