Right, the 300 is back from the menders and I have noticed a gash in the side wall of the OSR tyre. I have plenty of tread on all of the tyres and was planning to replace them with good quality AT's when they got all bolded. Now my hand has been forced what should I do? I don't want to replace all 4 boots right now because there is loads of life left in them (and I don't have lots of cash) but 1 BF Goodridge AT on one corner would look daft. Should I put gaffer tape over the split and keep going until all 4 tyres are racing slicks and I've had chance to save my pennies?
