	I though (rightly or wrongly) that....... Cross ply Tyres - Old tech, usless stuff that only vintage car owns bothered with Radial Tyres - Newer, better ect ...........but I assume I am now wrong, possibly. I was reading an artical about Rally Cross and how Kuhmo now sponser it, this upset some of the teams as now they have to run Kuhmo radials, where as they used to use cross ply. Now I am making a leap of faith by saying that 600+ bhp Rally Cross car using cross ply must mean they arnt that bad after all. Anyway I know someone on here will be able to sort out the confusion ;D

	They have different applications basically. As I know it crossplies have the steel bands running round the tyre and across it, radials run at 45 degrees round the tyre. Crossplies don't have much give in them and the sidewall is stiff while a radial appears softer and rolls about a lot more. Indeed crossplies don't grip very well but most of them are only 4" wide and made with 50 year old rubber technology. Drag tyres and truck tyres are crossplies as well as far as I know.

	perhaps its more to do with what the tyre is actually made out of rather than how they're made??

	I'm guessing that the rally cross crossplies are some sort of special modern racing super duper crossplies. Traditional old crossplies are truly awful at best (in my experience). A lot of American tyres are actually a kind of crossply construction - they call them bias belt radial.
	No more old cars
