Hi Guys

What do you find to be the best tyre pressure for road use.

I use Bridgestone SO3 225/45 17.

I am also changing up to 18 Speedline wheels soon with I think 225/40/18 tyres.

Dale,
IIRC Ralliart reccomendations are 32psi for the fronts and 28psi for the rears. Works well for me. Put a bit more in for trackdays though

i agree with andy,thats what mine are

 

[Guest]

Can someone translate that into kg/cm2 (bar)?

 

[Guest]

Rallyman,
That translates as 2.21 bar for the fronts and 1.93 bar for the rears.

Thanks for the conversion. I have been using slightly higher pressures (2.3 and 2.1). I'll try lowering them a bit.

Dragon, what 18 Speedlines are you looking to fit? Will you need spacers?

Thanks

with 17 on both Subaru GTT and now E6 I always use 34psi front/32psi rear, for track use I increase all with 4-5 psi more
