Outdoors run:
60Ds A slicks 53340 all around or with a S-Grips up front.....these are not the kit tires...they are much softer
On carpet:
We like to run either the S-Grips (53254) or M-Grips (50684) with the outer sidewall glued with CA to prevent roll overs and most of the time we run the Type A slick (53340) out back. I almost always use the (53255) hard foam inserts front and rear.
