Two quick questions? Was looking at the tire speck sticker on side of 5vr and it stated tire pressure at 90 psi . Fine except side wall on e rated tire is 80 psi. Asumming wrong sticker on Trailer. Second. Read one of the threads posted that said tire manufactor date followsv dot imprint on tire. If the first two numbers show the week of manufacture and the last 2 are the year yhen I might have a problem as aaccording to this info my tires were built the 10th week of 1999 Guess I better do some research.
