My 14 month old MCS has three Pirelli RFT with bubbles, They are summer tires and i want to replace them with all season, but finding 205/40R18 A/S is a nightmare. And thus thinking of switching to 215/40R18. I don''t have much snow (1-2" , 2-3 times a winter). Also would switching void warranty? Any suggestions and information would be greatly appreciated.

 

All it would void would be any factory tire warranty. It wouldn't effect any other part of the vehicle warranty.

 

Thank you for the information.

Just bear in mind that your speedo will be off a bit with the increase in diameter. Only about 1.3%, but worth keeping in mind
