At school we have these hella slanted curbs that are pretty nice sized... i went over one striaght on and really slow and i got hung up... my back tire sjust spun and spun and i made like a cloud of smoke! And burned half the tread off my driver side tire. So i had to reverse with some throttle and peeled out more. Next time i gotta go maybe 2 mph instead of 1mph to let my tires hop the curb... or just go 36" Tsl Radials! 6in 87' K5 w/ 35" BFG muds. 305/Sm465/ NP208 Kn, 4.56's. In desperate need of a rebuild. Next- Eaton mech locker... Flows.
