I just came from running losi super bolt-on tires(40 series) They had tremendous grip and hadled good too. I just switch to badlands with 1/2in offset 3.8in rims(relux 1/2 ups) well they are much lighter adn offer the much need slip the diffs needed. They handle well and offer quick responce. So far I like them(one thing you need to do is tape the inside of the tire) I tried a set of badlands with standard mt rims and wasnt taped and I didnt like there performance. Now that they are on the bigger rim and taped they seem to do good.
