Looking for recommendations please on what are the most puncture resistant roadie tyres, 700cx23. have currently got conti ultra sport that came with the bike, they are nearing a year old and have had 4 punctures in the last two days. It's not a thorn stuck in or anything 'cos once i've changed it it's fine for a good few miles more. but today i cycled to lincoln from my mum's house and rear tyre flat on getting back to bike. Got out of town and was just about to go back down the nice cycle path and got another one and didn't have any more tubes so couldn't risk another one so had to go back on the main road, during which it held air fine, but i've come to the conclusion my tyres are a bit crap and that I could get ones that are a lot better at staving off the p fairy.
