RE: i need help
The MT2 uses regular 2.2 size tires. For all around use the best tire that I know of is the Masher 2000's. They have great grip on just about everything.
If you put padle tires on the rear you should use ribbed tires on the front.
Bodies from a Traxxis Stampede will work fine on the MT2 and some of the original T-Maxx bodies will work also.
If you are going to run the truck in the mud don't forget to put balloons on the servos and seal up the battery box.
