Sorry if this has been discussed before but according to Tyre retailers, the PSI on my Superb Mk 11 Estate 4 x 4, tyre pressures should be 32/34 + 2 PSI when carrying loads.

However my front tyres, in particular, seem to wear on the outside although I have the tracking adjusted regularly.

My garage suggests upping the PSI to 38.

Any thoughts please?

self parking will wear tyres more. My tyre pressures are significantly more than the fuel cap detail recommends for each load situation in order to keep a consistent wear across the tyre.
