I'm sure many on here use Oponeo for tyres but just in case here's another plug.................

Just bought a Michelin PR3 160/60 17 rear for my Honda NC700X - £89 delivered in 48 hrs. Easily the best price I could find with cheapest fleabay listing (the barometer of low prices) being £98.95 delivered.

I've used Oponeo for the last 3 years for all my bike tyres (apart from NOS Anakees for the RE) and never had anything other than great service and great prices. One of the things I like most is the huge range and listing allowing you to often opt for 'last years model' and save even more.
