Only had two and they were within 1/2 mile of each other -one front and one rear.

But basically my fault. When I got the Pinnie in February- I did not like the feel of the tyres. Pinarello own brand and there was something about the ride of them I did not like. 700/23's and inflated to 120psi- same as I normally use. They did not give the right feel on cornering at speed and felt under-inflated on rough surface. Should have changed them as I carry spare tyres in the stock but didn't. Went over a rough path with a bit of debris and one puncture. OK-Spare tube and changed tube and nothing found in the tyre but that also meant Rubber on them. These are very lightweight tyres because they have minimal rubber on them. 1/2 mile later and rear tyre went down. I had already used my spare tube and the repair kit had a dried up tube of glue.

So my fault for not changing the OM tyres even though I had the feeling something was wrong with them- and my fault for not being prepared with a proper repair kit. They had done less than 1,000 miles and still had the mould marks on the centre of the tyre. So if anyone suggests that one tyre is a s good as another- tell them they are wrong..
