    Thinner Tires on a Comfort Bike?

    I have a comfort bike with 26x1.95 tires, which are smooth on the surface that makes contact with road, but knobby on the edges. I was wondering if I put 26x1.5 slick tires on if I would get much increase in speed/performance. I've heard different stories from different LBS's. One told me the difference would be noticeable, another said it would be a waste of money since the difference wouldn't be significant. Has anyone done this? Did it make any difference?

    The Alta Loma area of Rancho Cucamonga. About 45 miles east of Los Angeles, California. Uphill, downhill and across hill riding; not too level!

    I put thinner tires on my hybrid and did notice a definite decrease in resistance to my pedaling. My previous tires were much like you describe your present tires.

    I am running Geax RoadRunners on my bike right now. The tires and tubes aren't that expensive, go ahead and try it. Though if you run 90-100 lb pressure tires, the ride won't be quite so cush.
    I . . can . . . doooo . . . it

    They will make you faster, or you can go the same speed with less effort. So you won't be wasteful, wear out your current set first. Ride on dirt roads and trails while you can (before the conversion). Make sure the new tires are at least a little wider than your rims.

    From personal experience the thinner tires will be faster those tires with the knobs on the side are friggeen useless.]]

    I don't know if they'll make you any faster or not, but they'll definitely make you look less grandmother-ish. If it was my bike, I'd do it.

    Pump up hard what you have first to see if that's enough
    until you wear the tires out. Less wasteful that way.

    Any suggestion on brand, size or type of tires?

    Generally speaking, you will be able to accelerate faster due to the lower rotational weight of the tires. At a constant speed, the difference is much less obvious.

    I went from 26x1.95 Specialized Hemispheres to 1.5 Spec. Nimbus. Marked improvement on the roads. Gravel, different story. Small gravel, thery're fine. Larger, 3/4-1 inch stuff, not so fine. I will not go any smaller than the 1.5s since I have to ride a couple gravel roads. All in all, a most worthwhile investment.

    After 1,900 miles of riding on Geax Evolution 26 x 1.95 tires

    I switched to Ritchey Tom Slick 26 X 1.0 tires


    The difference was dramatic. I believe most of the difference is due to the smaller circumference. In essence the smaller tires changed my gearing so i have to ride a gear higher to ride the same speed as before. The bike does accelerate stronger and the steering is sharper, probably due to the much lower profile & reduction in gyroscopic effect due to the lower rotational mass.

    The ride is harsh however. I don't think I'd recommend going to the 1.0 (100 psi max) unless you're riding on nice smooth roads.

    Ritchey also has a Tom Slick in 26 x 1.4 (80 psi). That might be a good compromise.

    Also, keep in mind that when you find your tires, you may need smaller tubes too.

    Good luck.

    The Tom Slick used to be a great tire. They were OEM on Bridgestone XO bikes. They are still good, but not as nice as they were. I wanted faster, and tried going from the Tom Slicl in a 1.4 down to the one inch. Big mistake. The ride got harsh. Hard to believe, but that .4 inches makes a huge difference in ride quality.

    I ordered some IRC Metro 26x1.5 with PSI of 60-100 from an LBS. The current tires have a PSI up to 65. The LBS also recommended some Tioga 26x1.5 with a PSI up to 85. Do you think 100 PSI will be too harsh of a ride? Should I have ordered something with a lower PSI? He said I should be OK since the bike has a suspension fork and a suspension seat stem. He also said I could lower the pressure on the tires, if needed. What do you think?

    You can run any pressure you want. I prefer to run tires a little soft.
    You don't want a bulge showing where the rubber meets the road, but more than that is not needed.
    IRC makes a good budget tire. I am not familiar with that one, but they have an ok rep.

    I've been riding some Hutch top slick 1.2 for the past couple of weeks, after riding the Hutch Rock and Road 1.9 most of the summer. There is a big difference with a top sick like these or the Ritchey's . I pump them up about 85lb and they really have a lot more zip, plus there a ton ligher to.

    If the 1.5's are totally slick compared to the original 1.95's side knobbies they should corner faster on smooth roads. And as the others said they should also be noticeably faster with the lower weight and less rolling resistance.

    What do you think of the WTB Slickasaurus tires (26x1.5, 80 psi)?
