What fits what? - calling all nerds

Hi Team

i wonder if you might clarify something for me.

as we have now managed to get the 285/50R15 Pirelli P7 made again which were OE on the 79-84 cars, i'm wondering what else they will fit?

The 285/50R15 P7 can fit on a 8"-10" rim and the 225/50R15 P7 can do 6" - 8"

In my mind your earlier cars can still get 185/70VR15 XWX and 215/70VR15 XWX, so why mess with those. You have the perfect option. But then the 1972 - 1978 cars are in a bit of a tangle, There isnt really the perfect tyres out there. However they have 7" rims front and 8" rims (maybe 10") on the back. In my mind this slightly later P7 set up also fits on these rims, but does it fit in the body?

Hi Dougal

First a congratulations, and a sincere thank you, for your success in bringing the 285/50VR15 re-issue to market.

Yes the 225/50VR15 and 285/50RV15 P7's fit all narrow body cars the same. I guess that's your main question. But there's a difference in tire diameters, and the smaller P7's don't fit the wheel wells (designed for larger tires) as closely as Tjaarda had originally intended. The gap between the tire and fender is a bit 4WD-ish. Wheel off-sets are a bit wrong too. Instead of redesigning wheels or fenders, De Tomaso just made do with existing parts. Some people like that look ... it was after all the factory look of the GTS (narrow body Panteras) of the late '70s and '80s.
