Practically speaking, with 19 inch rims if you use Avon AM26 100/90 Roadriders front and rear, you will not find a better combination. Great handling and I have not had a wear issue
Agreed, brilliant tyres, if you run out of tyre then you'll have been on your arse for the previous minute anyway. I done a 4000 mile trip to Romania two years ago and was worried about longevity but the tyre came back and done another 2000 miles after that. Far better than TT100's and the old roadrunners and reasonable price also.
I run 18" on my John Player (only because its got CMA 3 spoke alloys on it) and its a PITA when you get carried away, despite the bullshit about higher profile tyres etc the stand grinds away all the time. Stick to original rims with roadriders in my (never wrong) opinion
