Seem to recall that one of the GT tyre suppliers had some issues at PI recently but can't remember which race meeting or which manufacturer.

To answer your question though would need a complex answer as tyres ain't simple. For example, GT tyres are wider, may not run anything like the same camber, are set up on the cars to get longer life (to keep pit stops short from a strategy standpoint) so less stress on the tyre, the cars are lighter and operate very differently in terms of roll stiffness, downforce etc. Plus on top of all that the tyre suppliers to GT3 have hundreds of cars running in various series and heaps of tracks all round the world so lots and lots of data to work with.

Dunlops for Supercar need to operate across a range of temperatures and a wide range of tracks and with the new construction the data is being collected from 28 or so cars. The testing of the tyres was reduced somewhat last year (in regards to PI) and so the development is still ongoing, made more intriguing by the teams ramping up the stress on the tyres this year with much higher camber angles.

Doing the test makes sense but it won't be easy as I mentioned as there'll be quite a few hoops to jump through.
