Hi guys, just wondering what tyre pressures you run? If it helps, it's a Haynes roadster, with a zetec engine and 195/50/15 tyres, mainly road use.

Cheers

Adrian

mine are 16psi 205/55/13 all four of them

I've got 195/50/R15 with 520kg total weight, and I run about 15psi (when cold) all round.

205/60 x 13 16 psi



Tried 20 psi once as an experiment and it was horrible

195 50 15 Bec 446kg

18 front 20 rear normally, tried 16/18 at llandow on sat and they werent warming up properly

I am running 205/50/15 with a Zetec , and i run 18psi all round

^^Mine are the same as dunk's^^

Running 195/50/15 with zetec in a Haynes Roadster, tyre pressure is 18psi all round.

Still experimenting. I'm currently on 18psi front, 20 rear. 195/50/R15 MK Indy, Pinto, Type 9, Protech coil overs shocks etc

When i first tried driving the car after the front end rebuild it was truly awful. Talk about streering that didnt centre - this baby took twice as much effort to return the wheel to centre than to steer away from it plus the suspension felt rock hard and i knew it hadn't been setup that way. I really wondered what on earth could be so far out and started looking at camber, caster and toe in - whilst what i should have done was just check the tyre pressures first.

Clearly tyre centres dont seem to know whats normal for lightweight cars.

The O/s front was the only tyre near right as this was the only one that hadn't been touched. The others had all been reseated or replaced and were between 35 psi and 38psi. Dropping the pressures instantly made the car tractable and pleasant to drive.

Could there be a further improvement by dropping the pressures down to 15psi all round with this setup or is that mainly for BECs ?
