I just noticed today that I have two different size front tires. Bought new from the dealer. I put 49 hours on. The right side is 8.3-16, which is correct for a L4400, 4WD. The left side is a 7-16 which belongs on a L3400, 4WD. Can having two different size front tires do any damage to the 4WD or anything else? Maybe a dumb question, but I'm new.
