Tire Width Choice...(5 posts)

Tire Width Choice...asphalt assault
Mar 1, 2003 11:30 AM
I'm trying to decide what width tires to get for the bike I'm building.

It looks like the most popular width is 23mm but I'd like to go with 20mm for less rolling resistance and besides, they look cool!

Any disadvantage to going a tad narrower? The tires I'm looking at are Michelin Axial Carbon. No racing, a few centuries no doubt. Just tooling around training for MTB.

with regards to tyre widths and rolling resistance, you'll find that 23mm's have less rolling resistance than 20mm tyre's, all down to the contact with the road surface, 23's basically give a rounder profile on a road surface, whereas 20's, due to them being narrower make for a squarer profile on the road surface, therefore, more rolling resistance, plus less chance of an impact puncture with 23's.

Better safe than sorry!

Good choice on tyres though!

hope this s of help.

Narrower = harsher rideKerry

But if you are quite light, then you can reduce the pressure and still get a smooth ride. However, if you are over 140-150 lb (64-68 kg) then you'll probably get a better overall ride from the wider tire. Rolling resistance will be roughly the same, with the higher pressure narrower tire deflecting about as much as the lower pressure wider tire. As to why you think skinny tires look cool, only you can explain that.
For that use, I think I'd go with 25-28.cory

I weigh 225, so I'm biased in favor of big tires. But for the kind of riding you've described, there's a lot to be said for larger tires at a slightly lower pressure. A few seconds off in a time trial isn't a problem for you, so why not be comfortable? The down side of larger tires is exaggerated, I think, except maybe for all-out jamming.

I keep 2 size tires; 23 vreds and cheap 25 house brands. 23's are harsher (particurally at 140psi) than 25's so hate to think what 20's would be. 23's are primary tires for typical riding. I put the 25's on when know ride will encounter brick roads in older midtown areas.

For training purposes and centuries, 23's are the way to go.
