Hello,

The wheels fitted to my B are 17" Matrix alloys with 215/40ZR17 tyres. Does anyone know what tyre pressures I should use with this set up.

I don't but the people fitting your tyres should be able to tell you. When I upgraded to 16" wheels and Michelin tyres the company contacted Michelin for advice.

I think it's worth doing as the Barchetta seems to be fairly sensitive to tyre pressures.
