They use 295/50R15, all of which are speed rated S. They also have to accept using different make and model tyres for the front and rear.

The 295/50R15 size tyre is 26.6 inches in diameter, 0.40" larger than the 285/50R15 size tyre. This creates two problems which people "live with". (1) The difference in diameter between that tyre and the 225/50R15 front tyre is 2.7", this upsets the intended level ride height of the chassis, giving the chassis a pronounced "nose-down" stance. (2)The 295/50R15 tyres "fill" the rear wheel arches more than the 225/50R15 front tyres fill the front wheel arches. This creates an aesthetic imbalance in the appearance of the car.

... in the late 1980’s, Garry Hall paid to have Campagnolo (by then Technomagnesio) restore the tooling for the 15” x 10” wheels that are used on the rear of a regular body Pantera. As part of the deal, Garry imported a container load of these wheels. I believe he sold all of them and I think it’s safe to say, the majority wound up with 285/50-15 P7’s mounted on them. Pirelli certainly knows how many they sold during the decade they were available. Gauging potential demand should be fairly easy and I’m sure it’s far more than 200 tires!



The majority of GTS and Group 3 Panteras were originally equipped with Goodyear Arrivas, only the small number manufactured after 1978 were originally equipped with 225/50 and 285/50 P7s. However, be assured that P7s eventually found their way onto all the earlier models as well. On top of that, as both David and I have tried to explain in our own ways, the factory's entire stock of spare 15 x 10 wheels, plus a cargo container load of additional wheels, have been installed on some of the 6,600 Pushbutton, Pre-L, and L model Panteras. The demand for the 15x10 wheel is so great that TWO aftermarket companies offer them. The aftermarket versions have not sold in large numbers simply because the proper tires have not been available. Suffice it to say that the demand for the 225/50 and 285/50 tyre set exceeds the demand for the 285/40 and 345/35 tyre set. A conservative estimate would be perhaps 600 cars.
