Wheell Alignments on TT etc and Michellin Sport Variants

Recommended Posts

After going through the recent Contis on the rear of TT on one side inner edge , in less than 3000kms if my memory serves me correctly  , im looking for some tyres but also some advice on alignment..

Im probably gonna go back to Pilot Sports … but wasnt sure on P3 vs P2 or  Super Sport, Do you have any experience  for road use.. shitty Byron roads at that ;) I wonder if there was any real difference..

Sourcing good tyres and at reasonably good prices is also a challenge and being the country area and topped with the fact that I cant be bothered to let the dealer have my car for a whole day which they ask for everytime I want any work done and drive the 70+kms and the need to mostly hire cars each way to them drives me nuts

Are their any known digital alignment /adjustments documented for cars lke the TT or am I worrying about nothing?

Whats your experience with digital/computerl alignments at non dealer facilities?

It may be the slow puncture/leak I had is just the culprit for the poor wear, or my right foot but with the new Boots I want to get an alignment check.

I can't comment on your choice of tyres, although I am very keen to hear the feedback, however the 993 wheel alignment process is rarely performed correctly.

The whole toe and camber thing is fairly standard and straightforward and can be set by almost any competent technician. Where it gets tricky is at the rear. Porsche decided to introduce a multilink suspension in the 993. In hard cornering the rear wheels' toe angle changes depending on the compression. This creates a passive rear steering effect which assists in beeping the 993 planted. If the Kinematic toe is not set properly the car can step out mid corner and wear tyres.

To effectively set the toe requires a factory tools or one of these http://www.carnewal.com/products/P93/p93163/Kinematic-Toe-Tool

Ray Hall tyres in Murwillumbah has a new state of the art WAM and a brilliant operator, Michael. 

Nice drive up here too.☺

They sell Michelin. I have ps3s and love em

FYI - Wont adjust Kinematic toe , even if I source tool , hence my question about the process

They seem like a real nice bunch though ..maybe to take the Escort there anyhow..

Suprisingly Michelin have one tyre PS2 N3 apparentlly  295/30/18 in stock country wide for the 996 Turbo Rims i have on my car..maybe that word is HAD

I moved on the old rims because in general i was sick of the tyre choice and like the 18 on the car , maybe I will have to try some 19. and a set of play rims

Too much mathematics 19's might have to hit 285/20'S or something

Scheesh, that's a bummer. At least they're honest. Which is what I like about them.

Sounds like a Porsche centre jobby.

Size does matter eh?

Yes 500 bucks to confirm you wont wear out $1000 of tyres.. bargain..

Great guys on the phone though , im gonna take the toy up there and get that sorted ;)

So how does it differ from the Weissach axle introduced in 1977 in the 928? The rear tyres certainly don't scrub out in 3000k in those old cars. 

Is it the engine hanging over the back axle that's causing problems again?
