well only way tires are faster is if there bigger. you must me what tires are better for it.
i used on mine proline maulchers for off road and road hogs for onroad.
max tires suck and you need custom hubs to fit becuse there bigger and the axle is bigger.
i used clod rims and ries on mine in the snow all you need are clod rims and tires and the tamiya parts bag for the hub and gearboxes it will give you the adapers and hex’s in the bag. and it makes your stampeed really really wide and it will never flip over.
and the tires are way bigger than maxx tires
