As Roelof stated the Tamiya Caps were awesome, and for a while Tamiya had some Super Grip Touring tires that had an awesome "rain style" tread that we would cut up and pull over the foams all while keeping a center rain sipe. If I can find them I'll post the part number, perhaps you may want to try a set. I think the racing in the rain was what taught me better throttle control.
