Evo is an updated EXP tire. EXP36-Evo or 30/40 is Sweeps high end racing rubber. It has more grip and last longer then the original EXP series tires. You can only order the new Evo in the EXP line so that's straight forward.
Guys above are talking about the "updated" QTS32 and 28 tires. The QTS32 is a widely used spec tire for carpet racing and isn't as fast as an EXP Evo but last longer and cost less. Its a running change I believe. John would have to clarify on that.
Straight off the US web site,
R stands for thicker long lasting radius for rough tracks. like Parking lots
E stands for Expert, EXP Sythetic rubbers. all out competition tires.
QTS stands for Quick traction System. Low profile tires mainly for Carpets.
OG is our all brand new rubbers designed for SPEC Racing. Carpet and Asphalts.
