UNIDIRECTIONAL UHP Tyres

[Tom-aadre]

Hi, had anyone got any recommendations for unidirection/directional (non-assymmetric) performance summer tyres?

My German super-wagon scrubs inside edges for fun and therefore I'm binning tyres that still have 4mm+ centre tread. I'd rather go to a tyre I can rotate, onece the inner edge is scrubbed, to almost double the life....

My first thought is it would be better to get the steering geometry sorted, then no need for the palaver with the tyres.

Unfortunately not the case, car runs lots of caster as standard

Potenza re050 and Yoko advan AD08rs are the two I aware of there may be more.

With respect, I think you must mean negative camber. Caster should have no effect on tyre wear as varying caster does not affect the area of tyre in contact with the road. Negative camber rotates the top of the wheel inwards there by putting the inside edges at risk of extra wear. It could also be that the alignment is out. Too much toe out will scrub the inside edges too.

A tyre fitter, when I had this problem, said that once the were has started the "shape" of the wheel changes and swopping them is not advised.

Not sure if there is any truth in the comment, but I do see where he is coming from

If it is an super wagon needing UHP tyres is it wise to run to 1.6mm?


Additionally, picking a tyre that is unidirectional but has a high wear rate may be less cost effective than a Michelin, for example.

The shape of the wheel doesn't change with WEAR on the tyre.

As was said by others I suspect you mean camber, and you are clearly running with far too much camber if this is the wear pattern you are seeing.

So to go back to the previous poster, yes you do need to get the alignment set up correctly, otherwise the issue still exists.

It does if wearing more on one side

The circumference on each edge will differ more than when it was new.

If I recall

shame of the tyre will though - which I suspect is what was meant?

You need to get your car sorted

Your car should not have one side scrubbed and the other side at 4mm

He said 4mm+ in the centre.
