Definitely go for F1s - you wont believe how good they are in they wet! I know BenR will disagree with me, as he always does, but there you go!
Not bad mileage out of them, but then a lot depends on how you drive - I remember BenR saying once that 1000miles was good out of a set of tyres!
The Ex must have had hers on about 6 months now and the fronts are just getting to the limit. She does about 18-20k a year so theyre not doing bad! Especially considering that when I pointed out they were looking a bit smeared
she said "Im not going any faster then you used to!" And I dont hang about when I get going!
