I have Motosport Alloy wheels and EFX tires. my tires are the Moto Grips. Not as aggressive as the Moto MTC, but are holding up to me spinning the tire all the time from the power of my Weber. Not disappointed at all with these tires. I will buy the Moto MTC if they come out with a 15" tire.
I have 2 sets of them....they wear like IRON...but they ride like it as well...After they get some age on them the get alot Harder than they were when New! I guess they would be good in Soft Sand but on Hard pack they SUCK!!!
