Wheel Complete; 6"SRT, Mach-12, 3/8"(PLASTIC WHEEL SPACER) (1158P)

Wheel complete; 6" Solid Rubber Tire, Mach-12 Wheel, 3/8" Bearings W/ Plastic Bearing Spacer.   

(Note:  Rear wheels on models with Quick Release Axles require a metal spacer PN: 1158M)

These tires are not mountable on the gen 1 gray style (Patmont) rims.  The complete tire/wheel/bearing assembly (PN: 1158M) can be used as a replacement.  

Note 2:

These tires or assemblies will not fit the original (pre-gen 1) 1985/86 "garage" Sport fork with the solid center black tire rims.  The solution for this would be to replace the fork assembly to accommodate the Go-Active tire.
