Tire concerns: bigger tires voiding car warranty
Will putting bigger tires on a Dodge Challenger void the car warranty? Will replacing 234-55-18 OEM tires with 255-55-18 tires void the car's warranty?
Actually this is a question you should be directing to either your car dealer or the manufacturer of the car because if there ever is a claim to be made on the car's warranty it will be the car company and not the tire company who will decide.
My opinion, as a tire dealer, is that if you simply wanted to change to a different BRAND of tire, then this should make no difference in the vehicle warranty.
When you start changing the size of the tire, even though in this case it is very limited, you are doing something which is affecting the way the vehicle will perform and if that change later results in a claim in the warranty, the manufacturer may be completely within their right to refuse to consider that claim.

to discover exactly what some of the changes in performance might be by changing these tires ... they are minimal in my opinion, but I'm not the one who would be responsible if you are making a vehicle warranty claim.
