Hi Dr

The car came with the B1 tires and were changed with the same type. I thought the newer B3 would be better but was informed by service rep they wear down quicker.

B for the PZero denote the higher load for the GT whereas non B are normal version thus costing a bit more.

I wonder if they use a different compound or what to get a higher load capacity? I was worried they just put the B on there to gouge us overly wealthy Bentley owners. That overly wealthy comment was a joke

 

My last msg meant to say the B are pricey than the non B.

I believe the higher loading could be from different ply/layer construction on the sidewall.

If they are more expensive because they are better then that is ok.
