All T1S tyres that I had on my Cossie 5 years back (went through a couple of sets) were brilliant.

Lynne - bit surprised to hear you run what are basically average road tyres (T1-R) on your track wheels? As track tyres go they are frankly rubbish.

Same also goes for Falken 452s - ABSOLUTELY NOT suitable for track use.

Mine after Croft - note the missing lumps of tread (brand new tyres 2 days before, now removed and binned after 220 miles track use ):



If you're as commited as you'd need to be to have "track wheels", you really should have track tyres - such as Toyo R888, Dunlop Direza D01J (sp), Yoko A048R etc.

Normal road tyres, as good as they may be, aren't good on track.

Back on topic though - if you have a genuine issue (not leaping on the bandwagon) with your Toyos, take them back to the supplier, who will return them to Toyo, who in turn (if they see fit) send it on to an independent test facilty to check them.

I certainly loved my T1S, T1Rs are supposed to superceed them so should be better still. My T1S I class in the same bracket as Goodyear F1s, Bridgestone's RE0 range, and on the road Falken 452s. Good CHEAP road tyres. Of course there are better ROAD tyres, and if you're doing enough track days or want the best performance, PLENTY of proper TRACK tyres.

I personally use Toyo R888s as they are cheap for the superior level of perfomance they offer, road and track year round. They only need a bit of common sense in proper monsoon conditions. But then who races like an arse when there are rivers on the road?

Then there's the Slicks option which is a whole other ball game!
