Tyres Direct 01582 585845 have 4 of them.

Actually, they quoted me delivery on 10th Jan, so I looked around for some elsewhere. I managed to get a set of 3, plus an odd one from another supplier, so, job done.

Anyway the guy at Tyres Direct had put his nose out of joint to find me some and he rang up saying that he had 4 being delivered the next day.

I felt a bit guilty having to tell him that he had been wasting his time. I might be able to do him and another board member a favour by posting this.
