Flat spotting tyres

I put my car on a SORN because of the virus on 1 May and don't expect to take it off until 31 August. I had read that increasing the tyre pressures to 40psi would protect them against flat spotting. Is this true? My local garage (specialist but not main dealer) now says I should start the car and just move it about third or half-a-tyre circumference every few weeks. Your advice appreciated please (as always). Thanks.

Slightly increasing the inflation pressure of the tyres by 3PSI will help to reduce the chances of flat-spotting. Just remember that you should never exceed the maximum recommended cold inflation pressure for your tyres.
