Designed for out door asphalt racing
in year 2010, Team sweep went out in many different tracks to come out with a answer for current Spec tires problem.
the problem was all of available spec tires are ether too hard for Spring and Fall-Winter season which makes racers ice skating. but too soft for the Summer, wears too much.
the Solution is here, R40 Asphalt SPEC
here is what Dean from Texas told us after testing run in Jan, 2011
"I just wanted to write to tell you that I tried out the R40 tires as you suggested and, you were right they worked just as good as the much softer tires we normally run in the colder weather. I must say I was apprehensive because we usually run 24 to 28 range tires when racing in the cold, but I tried the R40's and they worked great. I will definitely get some more on my next order. Thank you for the suggestion.

for sizzling weather testing, we will let a British guy do all the talking on a video below.

R40 created a "Greatest Touring Car race ever!" As always our spec tires set will not be available by tires by itself for peace of mind Tech inspection.
