Noticed that Beautiful Wife's bike tyres are looking a bit dodgy, not surprising as they were on the bike when I bought it used ca 12 years ago and it was probably a good ten to fifteen years old then. I've bought a set of Marathon plus tour tyres and will now start a complex round of 'cascading' tyres amongst the bikes, so the most heavily used bike gets the new tyres, and the next well used bikes gets the next set, and so on. Beautiful Wife rides within the local town and not in bad weather, but she'll appreciate the smoother tread of the Marathon plus tyres I expect.
