I tried asking this question in another thread but never received an answer so I thought I'd try here. (btw I tried calling Roger but he's gone today)
What does treadwear rating mean? I have a couple of different tires in my mind but I'd really like something reliable that is going to last for a while.
Is a treadwear rating of 480 good?
I have read descriptions like this:
"The Uniform Tire Quality Grading rating is a quality rating system developed by the American Department of Transportation. It is designed to tell consumers the relative performance of passenger tires.
Below is an example of a UTQG Rating:
The "150" indicates the treadwear rating
the "A" indicates traction
the "B" indicates temperature
The ratings are based on controlled conditions based on a particular course. A tire graded 150 would wear 1 and a half times as well as a tire graded 100. Traction ratings are AA, A, B, and C, from highest to lowest. This measurement indicates a tires ability to stop on wet pavement. Temperature ratings are as follows from highest to lowest: A, B and C. These measurements indicate the tire's ability to sustain high temperatures which often cause tires to wear away quickly or in extreme conditions lead to sudden tire failure."
but it still doesn't give me a good idea on how long the tires are going to last.
How long is a tire graded 100 supposed to last?
Thanks for putting up with all my noobish tire questions lately!
