"The beloved ET Street, the ET Street Radial, and the ET Street Radial II are going to be replaced by two new tires in March 2015, according to Ken Warner, vice president of marketing at Mickey Thompson Performance Tires & Wheels (M/T)."
"The new tires are the ET Street R and ET Street S/S. The ET Street R (yes, R is for race.) is the evolution of the original bias-ply ET Street for the guy who wanted the closest thing to a drag slick he could get and still be DOT approved. The R is available in both radial and bias-ply designs."
"The ET Street R comes in three different compounds: R2 on the radials, M5 on the bias 15-inch diameter tires, and X5 on the giant 34x18.50-16s for extreme classes! The ET Street R is not a steel-belted radial, it's a race tire you can use on the street."
"The ET Street S/S (street/strip) is for the guy who wants a street tire he can take to the racetrack. The S/S is a steel-belted radial that will fit 15- to 20-inch rim sizes. It still uses the R2 compound so it will be sticky and hook, but the stiffer carcass and improved tread pattern will handle better on the street."
