Yes, they're made by tomy and fit perfectly. In fact I think they are the same thing as the hard tires that come with the set. I'm in okinawa, so I'm not sure where to find them in your neck of the woods, but I think somebody mentioned they where at wall-mart.

Actually, I didn't come up with the pen idea. I'm just passing it on.
They don't sit flat, but they still work great. Some are extremely sticky too.

Oh, and one more trick, if you sand the back tires a little, they'll grip better.

AND, sorry one more, try to make the front end lighter (carefully). The BCGs are front heavy, thats one reason they like to spin out so much. If you do dual-cell mods, then try to get the batteries to sit as far back as you can. I just finished a dual-cell mod by taking out the peice of plastic between the battery compartment and the motor compartment. I didn't take it completely out. I wanted to keep some structure to the car. Now that car handles extremely well. In fact I put all stock tires back on it. It's god's gift to drifting too. Actually I think I'll expand with a new forum so everyone else get gain by it.
