You may not be able to go to another dealer and have them not know about the denial. I asked the service manager at the dealership where I bought my truck if he could adjust my computer for my new 255/85 tires. I wanted to correct the speedometer. He told me that if he had me in for service he would have to put into the D/C computer that I have other than stock tires on my truck. Keep in mind that this dealer sells trucks new with aftermarket wheels and tires. He also told me that they have been told to look out for any vehicle that comes in with larger than stock tires and to enter that into the computer. He told me that this would void my entire drivetrain warranty including axles, transmission, transfer case and engine. He told me that it easy to prove that the larger tires caused stresses in excess of those caused by stock tire size. Once you are in that computer you are screwed. It's not as easy as saying "they have to prove it caused the problem". You have to sue them before they have to prove anything! That can get very expensive very fast. This was of course a five star dealer. They must get a star for every so many hundred warranty denials they generate.
