Technical Tyre Pressures

[stocky]

My 500 is fitted with 145/70R12 69T radial tyres can anyone advise me what air pressure I should run them at please?

I would add 3 psi to the factory recommended pressures for the 125 tyres.

What pressure is that please?

 

[jjacob]

Factory recommended inflation pressure for radial tyres in the 125r12 size were:
Front - 16 psi (1.1 kg/cm2)
Rear - 23 psi (1.6 kg/cm2)

You should run these pressures or try about 3 psi higher.

My car is also fitted with 145R12s and the tyre fitter suggested pressures of 20psi (front) and 25psi (rear). With these pressures the car isn't too 'bouncy' and the tyre tread seems to be wearing evenly.
