I got two new hoops fitted by my regular tyre fitter, Don. His shop is littered with various dead two wheeled contraptions, mainly of the scooter variety and the shelves have a lot of dust covered items that will probably crumble in your hands if you bought them. However he always knows the latest info on tyre design and specs. Can look up availability on his computer for any brand you can think of. Plus he is very methodical when removing wheels and fitting tyres, every washer, nut and bolt is set aside carefully and he takes note of where they all go as he takes care of your bike. I think he can identify tyre size by just looking at them, doesn't even need to read the side wall. When I got there he was lacing a freshly chromed hub from a vintage Norton with new spokes. The owner hadn't taken a photo of the lacing pattern before dismantling it so Don had searched online and was lacing it from photos.
When I got my S10 a few months back it had a brand new Pirelli Scorpion Trail 2 on the rear and a very tired Michelin Road 5 Trail on the front. I was only going to replace the Michelin with a new Pirelli to match the rear but he had a set of Michelin Anakee Adventures on the rack so they went on instead. I was aiming to fit the Michelins eventually but I think I was always going to be in the situation where one tyre wore out before the other so I would be fitting a more dirt aggressive tire with a more road focused tyre. Bike is now set for a 3-4 day ride next week.
