Are you after real grip or something to mess around with?
Try wrapping tape around your tyres - might give you some cheap miles and practice drifting at the same time!
I'm sure that different types of tape will give different grip levels. The fabric style gaffa tape might actually have some traction, while cellotape would be the same as driving on ice
I've been using rubber on-road tyres and they do last a long time for me - about 20 minutes of warmup & racing _every week_ for over 6 months and still going strong. Cost me $65 with wheels on Ebay. 1/10 scale should be even cheaper.
I'm actually after tires that I could use for drifting a Nitro. So I thought cut uprubber hoses might give me less of a grip for drifting. I dont really want to use pvc tubing because that doesnt offer me any grip at all, and I might over rev my engine to death.
Well, I've thought about using tape, but that 2 isnt very grippy and quite messy as well.
