Note that these are not standardized, but vary by manufacturer. Some tires are rated 900A, but are no better than another maker's 390A

Whatever. A is better than C for both of the alpha grades.

Whatever. A is better than C for both of the alpha grades. > Yes, an "A' is better than a "C: when it comes to tire temperature ratings, but the rating has NOTHING to do with how much heat a tire generates. I should have said that the temperature rating refers to the tire's tolerance to heat, not resistance to heat. -- Ray O (correct punctuation to reply) |
