will the masher tires fit on the caldera 10e wheels or do u have to by new ones and what size to get.
no, they wont fit on the caldera's rims.
pick up a set of traxxas stampede (rear) 2.2 rims. the rear rims have the proper offset to work on the caldera. You can get the stock traxxas ones or ones made by RPM. Make sure you are looking at the stampede 2.2 rims....as the current stampedes use 3.8 rims.
I got a set of four traxxas stampede rear 2.2's for $13 shipped.
