If rolling resistance is the issue, wider is better, all things being equal. Sounds counterintuitive, but it's true. The reason your Paselas feel slow is not because they are wide, but because they are heavy, and they have a thick and fairly aggressive tread pattern. They are touring tires, after all, so that shouldn't surprise you too much.smokey422 said:I've been running Panaracer Pasela 700x35 tires on my Lemond Poprad. For less rolling resistance, can someone of my size (230#) run narrower tires, like a 700x23 or x25? This would be for pavement use only. Thanks for all replies.
Ken2 said:I use the Michelin Pro Race in 700 x 25 and it's a very comfy tire, and still light weight. They can be hard to find in shops but search mail order. BTW the Michelin 25 is comparable to a Panaracer ~30 or so--Panaracers are notoriously narrow for their rated sizing.
I realize they are a 700x25, but 5 bar (73 psi) seems REALLY low.ukiahb said:mine are rated 5-7 Bar (73-102 psi) on the sidewall and I run them at about 110 psi
I, too, weigh 235-240-ish (and dropping )...fearing the dreaded pinch-flats of yore, I had my LBS switch the 23mm tires that came stock on my RoubaixComp27 triple to a 25mm of the same design (SpecializedAllConditionPro) before I took delivery...I inflated the tires to an indicated 115psi f/r...so far, so good after ~100 miles of decent road surface...this is the most sophisticated and comfortable roadbike I've ever owned with its vibration/shock absorption technology, but I may drop the front pressure by up to an indicated 10% for even more balanced ratio of comfort/performance/efficiency...still, 115psi with these tires on this bike is not a harsh feeling ride at all for this re-entry newbie...I may eventually drop to a 23mm when I reach 200lbs (probably no worthwhile measurable mechanical advantage for a recreational clydesdale like me for the switch, just another 'goal/reward' like a CF bar/stem or cool new shades...personal mind games, really )...am I on the right track with my way of thinking (tire-wise/pressure-wise)?Tower said:and I'm 240'ish.
Specialized Armadillos in 23 have been indestructable. No flats in several thousand miles.
They're not the fastest or the softest riding tires out there, but I'll take a rougher ride over flats anyday.
