R-Compound Tires Listed in European Car Mag
European Car magazine for August 2004 has Part 3 of their tire guide, which is on R-compound tires. They define R compounds as commercially available tires that are D.O.T. certified and are considered driveable on the street. Here are highlights of the article:
R-compound tires still use radial construction techhnology, but feature strengthened sidewalls and super sticky rubber. Maximum tread grip starts at 8/32 in. and can be ordered shaved down to 3/32 in. But worry not, those grooves won't stay there long. UTQG is the industry standard for rating a tire's performance. The number represents the wear rating, followed by a letter traction rating and then a letter temperature rating. The lower the number, the faster the tire will wear out. For reference, the tires on a Chevy Impala have a UTQG wear rating of 560. Some race-governing bodies consider anything that has a UTQG of less than 140 not to be a street tire. The list below have a wear rating of less than 100, but can still be driven on the street. To check regulations on your autocross class, see their website at http://www.europeancarweb.com/. These tires are for die-hard at-speed junkies.
