Hot rodding was fine but just to experiment , I took the Schwalbe One TLE and put them on the winter bike cause it’s got loads of clearance. Then I took the Vredestein Fortezza Tubeless ( also 25s ) and put them on the summer bike. No rubbing and enough clearance not to be concerned. That’s fine however , and I say this even though I wouldn’t consider myself an authority on the matter…
The Schwalbe One - make my winter bike feel faster than my summer bike with the Vredesteins on. Hmm are Fortezza tubeless not that great rolling ? Rims are the same width internally , tyres are tubeless , pressures are the same
It’s fine , it works but ( and maybe I’m imagining it ) but my summer bike just doesn’t feel as sprightly with these tyres on and that leads me back to my original issue. What tubeless , 25c tyres come up less than 27mm on 21mm internal rims , it feels like that could be a problem that you could throw money at without having a great deal of success
Schwalbe One TLE are too tall , as are Michelin Pro 4 endurance with tubes but although the Vredesteins look fat , they have ample clearance. Obviously it wouldn’t be a problem on a more modern frame but again that would require serious investment and the reason I’m doing all this pondering is because even tyres alone is a hefty spend nowadays. I’ve been out a couple of times on my winter bike recently cause it’s been wet and I’m sure I was slightly faster , maybe I was just strong that day / those days.
There should be a chart that compares the real size of different tyres on different width rims that you can just look up what comes up the same size as what etc , otherwise you’re just stuck looking for anecdotal advice. The LBS isn’t just going to let you fit and inflate brand new tyres until you find the right ones
Anyway just pondering and venting and hoping for some discussion about the subject - I’m sure it’s particularly relevant for folks with older frames that are still obviously good/in use but need modern wheels amd therefore run into this very problem
