Trailer tyre 145r10 (Llynclys SY10)

I am looking for a spare tyre for my trailer, 145r10 as fitted to the original BMC Mini. I had a blowout and wrecked one of the tyres on my trailer so had to fit my spare. I now need another spare in case it happens again. Can collect any time to suit yourself. Please ring me, Iain, in Llynclys on 07940 722160. Thanks.
