Foam Trim: When assembling a new set of tires, I trim the foam so that it keeps the bead on the wheel exposed for easy gluing. If you don’t, the foam will get between the tire and wheel and bulge it out slightly. Morgan Jassen – Lompoc, CA For more Pit Tips, check out page 30 […]
A lot of people have speaker boxes in the back of their full-size vehicle and that makes it hard to use that space for anything else when you need it.

After tires, inserts and rims are all glued together, there often isn't a way to tell your various combos apart. When you finish putting a set together, write the insert's firmness, the tire's compound and the offset of the rim on each rim. This is a 53-compound tire with a medium insert on a 2mm offset rim.
Even if you drive an electric car, always keep fuel line in your toolbox. Besides its intended use, fuel line can be cut to any length to make bushings, spacers and wire insulators, and it can be used for many quick-fix remedies at the track.
If you want your tires to stick securely to chrome rims, you must thoroughly remove the rims' shiny surfaces (unless you have the latest Pro-Line chrome rims).

Be sure to work in a well-ventilated area.
A short piece of fuel tubing with a screw on each end makes a perfect container to store 5/64 to 3/32-inch diff balls. Squeeze some diff fluid inside the tubing before you insert the diff balls, and then you’ll be able to squeeze out one lubed diff ball at a time for easier diff building.
