Probably a mark of today's ever competitive world of cheap items, but these are rubbish. They don't thread properly. I bought a pair at a good price to put on my hybrid so I could get through the winter safely on my bike. All that happens when you try and put them on the rim is the innertube just pops out to say hello 30 seconds later. It's not a tight enough thread. I thought I wasn't threading properly at first but I did it and re-did it at least 40 times and it happened every time. It was back in July I bought these as I wanted to prepare my hybrid so it was all ready for rainy bike rides, but as I didn't use it I forgot about it and didn't send the tyres back. So in the dustbin they went. It's up to you of course, but I won't be buying Raleigh tyres again. Might as well throw my wallet away.
