Q. I have a 2005 Rover 75 TD with Goodyear 215/50 R17 91W tyres. I have kept the tyre pressure at 36 pounds per square inch (psi) front and 34psi back. Recently a garage recommended I reduce the pressure to 32psi all round. Who is right? SH, via email
A. You are both half-right. The owner’s handbook gives the recommended pressures for the diesel saloon for normal driving as 32psi front, 30psi rear. Only if you are regularly hitting the autobahn at more than 100mph should they be increased to 36psi front, 34psi rear. You may have seen this high-speed setting somewhere and mistaken it for the norm.
If you have the Tourer (estate) version, it is 34psi all round for normal driving and 36psi front, 34psi rear for high speeds. The pressure in the space-saver spare should be 60psi for all models.
