Wanted- one BFG A/T 31/10.5 r15

[biosurf]

Got these on my wheels but my spare is a different size.
Picked up all 4 wheels with the tyres for £100 secong hand so finding it difficult to swallow spending £90 to get the same tyre on my spare! Anyone got one knocking around?

cheers

I think I got one in my back yard, not sure if it's a general grabber or BFG though, I'll look later when I get home from work
