Granturismo 20" Neptune - what tyre sizes are you running?

[mcs]

Mine are:

Rear 285/35/ZR20
Front 245/35/ZR20

Someone told me today that these are incorrect sizes!?

Don't believe what you are told - sizes are correct.

What about load ratings and which tyres?

P Zero's all round

The 4.2 came with 19" wheels - albeit mot upgraded to 20" - which might explain the confusion.

As for P Zeros it's very confusing as they make about 3 front and 5 rear tyres in that size.

Thanks - checked with Marenello Egham and I am running the correct set up

Good news. Some people in the US are running Michelin Pilot Super Sports. Need someone here to try them out!

I'm on Pilot Super Sports, absolutely FANTASTIC.

Way way better than the OE Pirelli's.

In fact I'm getting mine fitted with some Michelin Pilot Sport Cup2's next week

F: 245/35/20 (stock is 255/35/20)
R: 305/30/20 (stock is 295/35/20)

Michelin tires are fantastic, rain handling is way better than standard and looking forward to testing them at the Goodwood Pistonheads trackday.

Thanks...will give them a go when new boots are needed

Re Activating the thread

I have Pirelli P Zeros on the front and need two new tyres as the insides are worn down badly and Im off to RAF Scampton at the weekend with the SuperCar club, the question is do I replace them with Pirellis or change them ? Is it ok to have pirellis on the rear and different ones on the front. ?

Save me a trip to Manchester to Marios as its a 100 mile trip, looking for someone near Burnley that I can get some fitted and geometry done.
