I managed to drive over a shard of metal outside a house that was being renovated. Don't mind too much as the tyre that was on the front cost £35 and I was planning on a change anyway so I ordered 1 Dunlop BluResponse - its got excellent reviews with the only issue being wear which I don't care about too much. I've got the fitting on Wednesday but I recall advice that tyres should be changed in pairs? Is this true, any advantages etc? I wouldn't mind changing the other front tyre but its going to eat nicely into my summer budget, believe it or not tyres weren't on that list. So do I change the front pair or just the blown tyre?
