I am interested in thoughts on optimum tyre pressures both for sprightly road use and track days for my series 1 coupe. Currently it is fitted with Michelin 175/70 R14 84H tyres and I have been experimenting with 34 to 40lbs. Thanks all!

This depends partly on the temperature of the track as well as many other factors, for example the quality and condition of your dampers and suspension bushes.

When I used tyres of this size on a Fulvia, I found that for road use, 27lbs front and 25lbs rear gave good results in average conditions (the recommendations in the handbook are rubbish). On the track, I would on a dry day, add about 6lbs all round, although of course if the track had mostly right hand bends, then I would run slightly lower pressures on the right-hand side of the car to enable more equal tyre temperatures.

Obviously in the wet I would run probably with my road pressures.

Thanks Paul, those pressures are quite a bit less than I had been trying, so I will have to try them!
