Volvo S60 D5 - 2005 model.


Assuming regular load, the recommendation for standard tyres is 31psi front, 30psi rear.

It is now fitted with Winter Tyres - Goodyear Ultra Grip GW3 Run Flat in 225/45/R17.

Any suggestions as to what the tyre pressures should be - I seem to recall on a Z4 I once had that the run flats needed a higher pressure than standard tyres.

Cheers in advance

ETA that the tyre fitters have put them between 36 and 41psi - not that this provides any measure whatsoever considering no two have the same pressure!

On my BMW the RFTs need to be kept at around 3bar (not sure what that equates to in psi) whereas my non-RFT winters are kept at 34psi
