No Tires On D/L'd Cars

I just downloaded the new 2003 F1 carset from Smoking Pen for GP32000. This is the first set of add-on cars I have used.

Can someone help me with what exactly I need to put in the tyres section of GPXPatch in order to have tires show up on the cars in the game. Otherwise, the cars look great!

Any help would be appreciated.
