M&H Racemaster 26/10.5-15 Cheater Slicks feature a bias ply construction, just like a regular drag racing slick, but they have "just enough" tread to pass DOT testing. Sizing is a little different on these tires compared to standard race tires, as the 10.5 width refers to the section width (not the tread width). For this particular tire, you can expect a 26 inch diameter, 8.5 inch tread width and 10.5 inch overall width. These street legal cheater slicks offer excellent traction with the popular M&H HB11 compound. M&H Racemaster tires are made in the USA!
