Hiya, I don't know if they are worth anything to anyone else?? However I am trying to replicate this car;
This was the car that won the 4wd Off Road championship in 93 & as you can see has the XTR tyres fitted... I would be interested in a couple of pairs if you still have them. Also I cannot quite work out from the pictures if you have the narrower front tyres or are they all rears? - If they are all rears then I could cut & shut a pair of rear tyres to make them narrower if need-be
Please PM me with what you have & how much.
