Im putting new fronts on and have the Vredsteins on the rear, Im tempted to move away from the P Zeros they have worn 1/2" on both inners again and having spoken to Bowkers Maserati they have said that is quite the norm but a painful expensive treat.

Two questions :

Anyone else get this type of wear ongoing ?

Vredsteins on the front - whats the difference between

Vredestein Ultrac Vorti - 245/35 R20 (95Y) XL TL (150 quid) and Vredestein Ultrac VortiR Ultrac Vorti R - 245/35 R20 (95Y) XL TL (200 quid)
and which one do I go for ?

Thanks

Stewart

Get the geometry properly set and you should be able to stop the inner edge wear. Or have you already tried that?

Talking to Bowkers they can do a setup for 200 quid, not had it done since bought it. What they said was to take it on a straight road, drive with white lines in the middle and see if it just drives straight with no pull and also to see if rears are wearing in normal tread pattern.

It feels that geometry setup required as that wear cant be normal can it ?

I think it's factory normal (i.e with toe out to make it sharper)

Blu and I had ours done at Northampton Motorsport for about half that. Great people and very happy to sit and chat to us about what we wanted and cars in general. Mine was set to basically dead ahead and it was transformed.

I don't know how these cats are setup. I use a geometry specialist who does nothing else but chassis tuning to set up the car as the owner wants. I recommend them:

Center Gravity in Atherstone Warwickshire (yes its spelt Center, not Centre).
Contact via their website. Both Chris (Franklin) and Pete know this subject well.

I had the Porsche set up by them. I drove the Maser to him (200 mile round trip), gave him the keys and he took me on his mix of roads to test the geometry suspension and pronounced it has slight left bias, keep an eye on tear wear and if uneven, get in touch. Otherwise he said the cars suspension is fine.

Might be worth an email via his web site - ask him to call you when he has a moment and discuss it. You can mention me (Cheshire911 or Amit) to jog his memory.

I believe the geo is a part of the regular service on the GT, not just the 4 year/25k major service but the 2 year/12,5000 one also. When was yours last serviced?
Good move to leave the P-Zeros behind though in my opinion, especially at this time of year

Agreed...I put 4 new Michelin Pilot Super Sports on mine and it's made so much difference in the wet. It doesn't feel like the GTS is trying to kill me any more.

Minor service few months ago, had 25k one done when bought her a few years ago. Im moving from the P Zeros, easier to get but not going to like them at all and think going for the VredSteins trying to work out what the R means on the higher price tyre

Got the answer from CamTyres

The Ultrac Vorti R is Vredestein’s most sporty Ultra High Performance summer tyre to date. Compared to the Ultrac Vorti, the emphasis with the Ultrac Vorti R lies with ensuring grip and driving precision for the most powerful cars. The tyre maintains its traction at higher temperatures, including on bends, and is exceptionally stable at high speeds. It is therefore the ideal partner for four-wheel and rear-wheel drive sports cars that demand the most from their tyres. The Ultrac Vorti R was developed in close cooperation with Italian design company Giugiaro, and the carbon accents on the sidewall and in the tread are a design feature unique to this tyre. It is available in several sizes that have been specifically optimised for the rear axle. They include an adjusted belt angle and an even lower air ratio, with an increased focus on maintaining grip on dry surfaces (as the front tyres discharge most of the water on wet roads).

They are the first tyres to be constructed wholly of cheese. See the following video:

as mentioned, inner edge wear doesn't have anything to do with tires, it's all about toe-out. toe-out also isn't really something you'll feel pulling, you have to measure it.

just go against the factory specs like catman says and put 0° of toe.
