Tyre pressures
My car is feeling very slippy on these damp roads. What tyre pressures are people running? I'm running about 23psi in a car which weighs
550kg.
Can't even get more than 1/3 throttle without back end stepping out of line. thanks

Don't know if it's the best setting but I'm using 18psi. in mine which so far seems to be OK. Think I got the pressures from a
previous post.

I use 18psi as well - I could probably go lower!
The tyres work well at this pressure, so I'm reluctant to mess around.

i run 16 psi all round,
my car does not like wet roads at all, not helped by 205/13" tyres, way to wide, but do look cool

Yeah, I run 15-16 psi all round, doesn't seem to help traction in this weather, had a bit of power wheelspin in third at the weekend. From a
fairly standard 1.6 GT xflow....

Teens of PSI is normal - I have seen people run 13psi

As above...
I run 16psi with my current tyres (Bridgestone S02's). Dropped them to 11psi experimenting at a trackday recently. Used to run 18 with my first
set of Goodyears.
But even with lower pressures, as mentioned above too, don't expect a huge difference in grip at this time of year. The lack of weight with this
type of car is a distinct disadvantage in cold/wet weather.
IMHO this is one of the best times of year to go blatting (except for salt  ) if only to re-affirm the respect one must have for this type of
car...

im on 205/40 /17 what pressure would you run on them i asked the tyre suppliers and they said 26psi.
although looking at the tyre wear i would say that its to hard.

The pressure you need depends a lot on the tyres and the weight of the car. I'd suggest you start around the 18psi mark, and then experiment
around there (a couple of psi at a time) until you find something that works for your partticular setup.
I'm running Yoko A038's on mine and have the pressure at 18psi, and that works really well for me once the tyres have warmed up.
However, at this time of the year its *always* slippery in these kinds of cars. The trick to minimising wheelspin is judicious control of the
accelerator
