Discussion
I've had my M12 for nearly two years now, but have only just joined this great forum.
I've worn out the rear tyres ( Bridgestone S02's ), so I've looked back through the various threads over the last few months and I'm thinking of going for the
Goodyear F1-A's - 265/35/18 rear and 225/40/18 front.
Is that a good choice? I've been quoted £536 fitted.
Finally, is 27 rear and 17 front the right pressures for these tyres?

I use Bridgestone Potenza RE050A for the same price and I have no issues with them, they are good enough for all weather driving.
I thought it was 18 front 27 rear?

I have done about 1000 miles on my Goodyr F1 got to say chuffed as nuts with them so much better than the SO3 s i took off that price sounds fare i got mine for £500 but ma mate is the manager of the garage and i got his discount vouchers from him. Go for it you wont be disopointed or i will eat ma hat
Had the the Goodyears F1 -A's fitted this afternoon at Micheldever Tyres. Price was £522, so a bit less than quoted.
I've only dirven about 15 miles so far but first impressions are that they are much quieter and the car has a much softer ride than on the Bridgestones.
I'm doing a track day at the Le Mans Bugatti circuit on Monday so that will be the real test!
Thanks for everyones comments.

Congratulations on the new rubber.
But as a cautionary note: in general, new tires (aka tyres) at full tread depth will tend to "chunk" (large blocks of rubber ripped from the tread) if driven hard before they are "seasoned" with 200-500 road miles. The problem is excessive heat build up coupled with too much rubber to dissipate the heat adequately. The edges of the tires should be inspected carefully after each run on the track, and if you start to see evidence of chunking it probably would be best to stop driving before the tires are ruined. It will also help to increase tire pressure 2-4 lbs all around before driving the car hard.

Good advise...the alternative is to buy a set of slicks for track days But as a cautionary note: in general, new tires (aka tyres) at full tread depth will tend to "chunk" (large blocks of rubber ripped from the tread) if driven hard before they are "seasoned" with 200-500 road miles.

Thanks for the advice. I should get about 300 miles in before I get onto the track.
Would having the tyres nitrogen filled help? I should have thought about it whilst the tyres were being fitted, but I could go back tommorrow .
Not really since the air you breath is almost 80% nitrogen already. Filling tires with 100% dry nitrogen can reduce pressure increases associated with heating the water vapor that is part of compressed air, so hot tire pressures will be somewhat more stable and predictable when a tire is filled with nitrogen. But the effect is pretty small so it won't affect tire chunking and it's not likely to be detected unless you and your car are very sensitive to small changes in tire pressures.
