Different Tyres for Chimaera?
Discussion
After reading all the inputs from everyone about the handling properties of the Griff, and comparisons between the Bridgestone S02 and S03 tyres, has anyone out there gone to a different tyre besides the Bridgestones?
I would be willing to try something different to improve handling.

If you want to know the current vogue for the best handling tyres, look around the sprint paddock. If changing a tyre could give a few extra tenths we would change. Guess what, all the front runners are on Bridgestones.

Steve, would it be correct to assume tyres good for the track are good for the road. I'm thinking of things like truck ruts, cats eyes, potholes and the fact that on the track your temps will be typically much higher than the road....not done a track day yet so don't know
For the production and road going classes, the regs say you have to use road legal tyres. Sticky cut slicks and other dodgy tyres are not allowed. So we have to use road tyres from a list that has the majority of the recognised makes and types on it.
Sprinting is also done on cold tyres. Tyre warming is generally not allowed and we don't have the courtesy of letting the tyres warm up before going for it like the nimbypimby racers do So in reality it is very similar to driving on roads. Some circuits can be quite rough and others are smooth so you need a tyre that copes with both. And with wet and dry conditions. Exactly the same conditions as people experience on public roads except that we race in them.
Yokos used to be the fave when I started about 5 years ago but Bridgestone have dominated since then. I changed and the difference was unbelievable.
As for track days... Depends on how the car is driven and set up and where the day is being held. Mallory is really tough and I usually can say good bye to the lefthand front and rear. Bigger circuits like Goodwood are not so intense so the tyres can last better. Biggest problem is incorect tyre pressures causing localised overheating and this can result in the tread peeling away from the carcass. Softer tyres like Toyos and Falkens seem to be more prone to this and they can go off very quickly as a result. You start getting a lot of understeer that needs a lot of serious welly to overcome and maintain the car in the direction required.
Bridgestones will go off as well but the threshold is usually a little bit later. They just seem to be about the best compromise tyre available at the moment.

But Steve we all know you have been stockpiling SO2pp's which tells me you are a little cautious about the SO3's ? Rich...
Well when I stockpiled the S02s, delivery on the S03s was a little unknown and I was offered such a good deal that it would have been irresponsible of me to turn it down. Yes changing a tyre is a bit of an unknown and yes I would rather let someone else try it but several of the S03 sprinters have been winning their class and setting good times. When my stock pile runs out I'll change over. The only alternative is Toyo Proxie and I don't think they will last as they are too soft and complient. My feeling is that the 520 would probably shred them as a result. Thinking of fitting S03 to the shopping trolley first and experimenting with tyre pressures etc on that first though to get some idea of how to set them up and then run a set on a track before changing completely.
However, all this is really due to the fact that the 520 is a race car now first and foremost.
