Correct tyre pressures

[blip]

Anyone help ?... need to know what the correct pressures should be for 18 in spiders with bridgestone tyres on a red rose tusc.

[Luca Brazzi]

I'd like to know too

...the manual only talks about 16" wheels, to be at 22psi...

Mole Valley said use the same on 18"...what do you all think?

Mine are 24psi

I was told by the chassis engineer at TVR to use 22psi front and 24psi rear on 18" spiders with RR suspension.
Hope this helps.

Many thanks John.

Yep, 22 and 24 is correct according to Henley Heritage.

I have a Tuscan RR and use 22psi front and 24psi rear as recommend by TVR. Have been using these for a year and it works pretty well...

I had the same confirmed this morning. However for greater speeds (track days etc) you should be looking at upto 28psi.

There should not be much (if any) change in the tyre pressures because the weight of the car has not changed much (if any).

[Graham and Rosie]

It is more to do with the higher loads on the car due to high speed cornering so a higher tyre pressure keeps the side walls more rigid and so causes less wear on the tryes and better grip - I think!
