I have a MTB with 26x1.75 road tires. I want to go to a narrower tire such as a 26x1.0. Can I use the same rims?

100 psi 1.25 will work...

This THE RIGHT TYRE WIDTH ON THE RIGHT RIM WIDTH - Engineerstalk : Engineerstalk

The rim-tire might work, but why would you want to go so narrow? The trend is to wider tires.

You sure? There are some fat and fast options in 26" tires these days. I wouldn't ride 1" tires on anything.

Ok, thanks. I'm open to suggestions about the optimal tire width for a road tire on a MTB. (I'm still fairly new to this).

That's a 19mm drop. Significant. You might do some math to see how that will affect potential pedal strike and how much it will reduce trail.

I would stay with the same size and look at a superior tire if your budget allows.

What's on the bike now?

These aren't cheap, but I can tell you that they are light, fast, roll forever, and offer a ridiculously plush ride.

These were my non-winter tires of choice for several years:



Got a set of the aforementioned 1.8" Naches Pass to install once the snow and ice are gone this year. Can't wait!

IF you find a 1.00" tire, you'd have to run very high pressure to prevent pinch flats, which makes them hard as a rock.
A 1.25" "should" fit most any "common" MB rim without issue.
It's what I use.

Reducing .75" from your tire size can be made to work, but may do weird things to the handling and increase the risk of pedal strike. Also, what's the point?

If you insist on going narrow, Continental makes a 28mm version of their Grand Prix for 26" wheels. A bit larger than 1", and a decent tire.

On a budget, without the narrowness requirement, I'd probably go for a 26x1.75" Pasela.

Not on a budget, I'd go with a 26" Compass tire.

//=====================

If you want something bombproof and don't mind up loosing some speed, maybe look into 26" options from Schwalbe's Marathon lineup.

I just read up on those Paselas. Close to ~500 grams. If you bought the EL version of the Naches Pass, you are going to lose almost a POUND of rotating mass. That's gonna be huuuuuuuge.

I'm too much of a chicken to venture into EL tires yet (my bikes get knocked around on group rides), so I just got the regular ones. Even if they turn out to be little more than Paselas with folding beads and a tubular-style tread, I will be a happy man.

(240 gram total savings by my math.)

As above, 1.0 is quite extreme. A 1.0" wide tire would work well on a very narrow rim which is unusual for most modern MTB's. (There was a period in the late '80's/early '90's where 19mm rim MTB rims were a "thing".)

I put 1.25" Tioga City Slickers on 23mm wide Mavic rims in, umm.... 1993? They worked really well and rolled well inflated to 95psi (I think). That's as narrow as I would go on a "normal" MTB rim.

Of current tires, I've used Schwalbe Kojaks on a couple bikes. Their 26 x 1.35" would work well for you:

26" wheels are relatively small diameter as they are. I don't like narrower than 1.75 on those wheels. If you want higher speed, get good quality slick(er) tyres, but I'd advise against going narrower. Definitely above 1.5", though I find 1.75 a sweet spot between weight (narrower are lighter) and (the pluses of wider tyres): larger wheel diameter, more comfortable ride, lower pressure (makes punctures less likely).

What kind of riding do you do? A 1" tire would not perform well if you do any off-road riding.

If you're just looking for better performance on pavement, switch to a slightly narrower tire than you currently have, with less aggressive tread. The Panaracer Pasela suggested above by [MENTION=251447]ThermionicScott[/MENTION] is a good value.

not if the rim is just 1" wide, try .25" less, 1.5"...

Thanks to everyone who provided information about my question. You have given me really good options to consider. Much appreciated.

What didn't get discussed is the rim width. Some older MTB rims were made out of 700c road rims and will work easily with a 1" tire. Others are too wide and may allow the tire to blow off the rim. What kind of rims do you have?

Well, I did make a peripheral mention of rim width above. ^^^
