newbie tyre pressure

[crainbow]

Hi guys there doesnt seem to be a straight answer on this so does anyone know the standard
pressure ?

Am running pirelli p7000 16's and am just finding out that these are a budget tyre
So i think i will be swopping these ??
but in the mean time what pressure should i be running these tyre's on at the moment
fronts are 22 psi
rears are 37 and 33 psi ??

anyone help ???

thank you
chris

What car do you have? Fronts look low and rears too high.

They are on a R reg 450 chimaera if this helps ???

i have 24 all round seem fine to me i have a 4l chim

Have seen some info with people running 24 psi but some others running lower and higher

Handbook says for Bridgestone S02 (standard fitted tyres)

Front - 22psi
Rear - 24psi

Remember as the car only weighs over a 1000 kilos you don't need to have 30+ psi tyre pressures for normal road use.

Your car must feel like you're driving on ice. 24psi - just try it!

Must be some interesting handling - I hated P6000s on a Focus let alone a TVR, and with those pressures!!

Back in 98 a tyre dealer replaced the tyres on my chim 450. A famous place near Winchester. Car felt floaty and horrid especially at high speed. So on way back I checked the pressures. They were 30ish all round and the car felt dangerous. Yours must be almost undriveable...!?

the handbook says F22 R24 but that was with the old S02's which had IIRC quite a firm sidewall. Most of the favoured tyres for the chim now have a softer sidewall. I have Dunlop SP9000's front and Falken FK452's rear and run F24 R26. Lower than this and things get a bit squidgy (ok ok, its not a tech term but thats how it feels) . Higher than this and things get slippery, like driving on ice.

At the pressure you are running on the rear I'm surprised you dont find yourself doing a 180 on every roundabout.

Hi guys

thank you for all the info went out and dropped the tyre pressure to 24 psi all round and has made a massive difference to the car feels

This is what I use, got Dunlops on the front and don't enjoy them, some terrible understeer, I find at 22psi there is just enough to help the turn in.

Wasn't just me then, although I think mine were a little more than that.

What springs/dampers you're running and their condition could also influence the ride quality. I suggest having set 24 psi as a base you now start tinkering by adjusting them by 1 or 2 psi to get to where you're very satisfied with the handling. Even a small adjustment can make a difference
