I use Mavic 717 rims and use Conti Grand prix tyres. These are the width of Roadie slicks and are high pressure tyres. That is something to remember because with high pressure tyres- you find out if the rims are on the way out. I do keep a pair of Old 217 rims for the road tyres and these are still in perfect condition. If you pump the tyres up to pressure and find the Braking surface goes remotely concave- Don't use them for high pressure tyres
