original68

hello first time poster. I am trying to locate production numbers/options on from the factory. My problem is my extende warranty company cancelled warranty and/ denied a claim based on oversized tires I have 275/55/20 on the car( a factory option on the denali) does anyone know where to find how many yukon xl's were delivered from the factory with this size tire. my yukon came with 265/70/16 however was told by dealer the 20's were a factory/dealer option. any help will be greatly appreciated. I need the info to stick it to the extended warranty company. or does anyone on this fourm have a 2005 yukon xl with the 20's from the factory

kyfdx thanks for that info i will print up that and add it to the file for court. i still need to show at least 1 gmc yukon xl leaving the factory with the 20s and i will have the warranty company wishing they had paid the claim. thanks
