Treadwear Rating
A tyre treadwear rating grade is a comparative index established by the
American Government to give consumers a guide to the wear rate of the tyre when
tested under controlled conditions, for example:
A tyre graded 150 would wear one-and-half times as well in controlled
conditions as a tyre graded 100.
The American Government requires a Treadwear Rating Guide to be moulded on
every tyre's sidewall.
In the UK, tyres do not (by law) need to have a Treadwear Rating Guide on
tyre sidewalls.
