My class C came with brand new ( the nubs were stil on the treads of the tire) not just on the sidewall. The DOT code on the tire is 5KRQ RC? What is that date code come out to?
The date code is in a series of characters that start with DOT and ends with 4 numbers. The first 2 numbers of the 4 are the week and the last 2 are the year.
