the mashers are quite a bit heavier, and will slow it down a tad. But they are so big they act like a 2nd set of shocks
In my case I need bigger tires for when I drive out front due to the poor state my street is in(or what the city calls a street). I mainly own MT's for a reason


On the Lightning GT10 tires They were DC'd a while back I bought them straight from hotbodies over a year ago when they did a giant blow out sale to get rid of the overstock on DC'd RC parts they had (also picked up 3 sets of savage tires + rims for $5-$10 a set, and 8 sets of 1/10th scale buggy tires for $3 a set ) Finding a set now might be extremely hard. I also needed to get 14mm hex's (think they came from a pede) to use the rims.
