I have self-made "hybrid" bike that uses 27mmx559mm (i.e., 26") Sun Rhyno Lite rims with 26"x1.75" Continental Top Touring 2000 tires. These tires are awesome but have worn away after about 10 years (5k miles) service.
All my riding these days are pavement/road with the bike below (used for grocery, errands mostly). I don't weigh that much but my rear panniers can accumulate up to 40lbs (gentle riding over mostly smooth pavement or road).
Using the SAME rims, what's the min. tire width I can get away with?
(Replacement tire will most likely be 1.5" or 1.6" Kenda or Geax. But a 1.25" width appeals to be for fast speed. FWIW, this chart (also shown below) suggests 1.5" to be the min. "recommended" width for 27mm wide rims.)
Thx for any feedback you can provide!!
