I'm doing up an old C90. My wife has expressed an interest in using it to go to and from the Stables in the better weather. They are around 7 miles from home, four or five of which are B,C or even single track roads and get a good deposit of mud and stones from the surrounding fields every time it rains. The current tyres are circa 1970 and will need to be replaced and I rather think something with a block pattern (but not full off road type trials) would be better than the ribbed front, square ziz-zag Avons currently fitted. Your suggestions welcomed.
