Cross ply tyre FAQ
A: there was a brief period where tubeless crossply tyres were being made, however at this time the majority of cars were moving onto radial tyres.
A: Although the radial tyre was patented in 1946, it was seen as a performance upgrade in many cases. It became more standard in Europe towards the moddle of the 1960s and didn’t become the predominant fitment in the States until 1970!
A: The majority of road car tyres are radial. Though many vintage cars and classic cars still fit crossply tyres.
A No in the majority of cases a radial tyre will last longer than a radial tyre, because the crossply tyre carcass flexes while the tread is in contact with the road. Scrubbing the tread off.
A: it is strongly advised not to mix cross ply tyres on a car. It is illegal to mix crossply and radial on an axle, but for some reason it is legal to have cross ply on the front axle and radial tyres on the rear. We recommend having the tyres of the same structure and age all-round the car. Mixing tyres is not recommended and can be illegal.
A: predominantly cross ply tyres have their sizes written in inches where radial tyres are mostly in inches. For instance 6.00V16 is the crossply size tyre for an XK12 Jaguar and 185VR16 is the radial option. 5.60-15 is the original crossply tyres size for the classic VW Beetle, that would fit 155R15 or 165R15 radials.
