I think they are both 2.2, so you should be able to use the same tyres.  Best setup is probably to drop the suspension by removing the spacers because it is a bit too high to handle well being a stadium truck, plus there are no anti-roll bars fitted.  I wouldn't bother with the Venom road tyres from Schumacher; I have a pair and they are rubbish.  Best to try another on-road tyre, or even a wheel & tyre set meant for the Menace GTR.
