Mod 2 – Foam Tyres
Purpose – The traction of most Race Tin tyres isn t enough once the car is upgraded, so here s how to make some cheap foam tyres for use on carpet etc.
Parts – Conductive Foam (from Jaycar) or other substitute
Tools – Sharp knife (eg hobby scalpel etc), Sandpaper
Warnings – Be careful with that knife kiddies.
Step 1 – Cut out a piece of foam slightly larger than the tyre you are going to make (you can use your old tyres as a guide.
Step 2 – Cut a hole in the center smaller than the rim you ll be putting the tyre on, (A very snug fit is important or the rim will spin inside the tyre.
Step 3 – roll up the sandpaper into a tube (rough side out) and use it to smooth out the hole you just cut.
Step 4 – Cut groves into the foam to match the raised parts of the hub, again too small is better than to large as a snug fit prevents the hub spinning in the tyre.
Step 5 – put the tyre on your car, jam the remote in forward and sand the outer part of the tyre until the shape is right.
Step 6 – repeat for as many tyres as you need.
These tyres seem fine for Stock Race Tins (with a 4 cell mod) on carpet, they will give different results on different surfaces.
