Hi, just took the plunge and started commuting the 14miles to work & back each day. I have already got a Mountain bike, which had been more or less sitting in the shed since purchase nearly 5 years ago! It's nothing special, just a hardtail raleigh 26" mountain bike. The tyres however are obviously designed for off road use are are very knobbley! I've recently picked up this mag (well overpriced!) called Ride to Work. It mentions briefly in it to "fit nice fast XC style tyre around 1.75 to 2in" (perfect jargon for the begginers its aimed at!) So I'm going to b shopping at Halfords or Go Outdoors - what actual tyre should I buy & will it make ANY real difference to whats on it now?? Thanks for reading, Kosh.
