The Carlisle ''turf saver 2'' - 15/6/6 tires is what I run on the back of my E- Kart. They are 2 ply,, & with 8 - 10psi in them,, they ride really well & smooth on the streets.. Have also pretty good rebound,, & only cost around 15 bucks ea. with free ship,, on the Wally world site.
Also run the turf saver 2 - 13/5/6 ones on the front of my Kart,, with around 6 - 8 psi in those. Same price as the other ones also.
Really like them,, & they don' t have to much tread for street running.
