I pulled out all the lap-time data from the on-line Tire-Rack's tyre tests. I included only the tyres that are known to me but if anyone wants, I'll add other tyres in there. Here's the tabulated laptimes sorted by the 'dry; lap times:

ps. Some tyres are in there more than once as they were tested more than once and got different times (just goes to show that conditions/temperature must make enough difference to put them in different order).
