the stock tires are terrible once you go through a set i would not look back at those...especially if you are running 3s and upgraded pinion and spur gears they will just fall off.
there are 3 really good options
1) traxxas 7073 tire/rim combo you will need losi hex set losb1931 for it to work....they onlly work in the rear
2) traxxas 7071 tires mounted on losi rims
3) losi larger diameter rims from mini slider losb1196 (not sure on the pn)
my tire after 1 week
here are the traxxas tires mounted on the stock wheels
