ok try this if you think skinny tires dont work... if you have a 2wd truck that can run same tires on front as rear... stick a rib on the rear i bet it lock you rear end in place at speed.. but good luck trying to get to speed. also this the same reason why a double dees(on truck) will make side grip than a hole shot even at a harder compound. on a 2wd buggy it is harder to tell cuz the tire are already narrow. the width of a tire plays a big role in side grip (not just in ice). this is main reason why a 1/8 buggy slides less than a 1/8 truggy 2nd reason is off-set of the tire also plays a big role in side grip if you run less off-set you will have a ton more grip (any one that try a old xxx losi rim a old associated t3/t4 pin would know). this is why easy to find more grip in a 1/10 buggy vs 1/10 truck where you would need to add a lot more weight to = grip.
