slick tire on mountain bike

hello every body

im just planning to replace my 26'' x 2.5 (62-559) mountain bike tires with slick 26'' x 1.5, as to be more easier on paved road.

MY QUESTION is will the new tires fit the same rim? or should i change the rim also?

have any one tried something like this before? will it make huge difference?

thank you all

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

The 1.5" tires will fit your 559mm rims as fa as diameter goes. However the rims may wider than ideal for the tires. The general guideline is that the tire should be rough (very roughly) 1.5x the inside of the rim. Here's a chart that will offer some guidance


There's plenty of fudge room to either side, but the tires handling characteristics change. If you're at close go with it, or consider a slightly wider slick tire. It's not necessary or worth the cost to replace the rims.

i'm using the original rims that came on my stumpjumper. i run 1.25 tires on it. absolutely no problem. i'm riding on pavement.

and i toured a long way on a bike designed for 650c (571mm) wheels. part way through the tour i switched to 26" (559mm) rims designed for mtb's (a mavic of some sort). i ran a 1" in front and a 1.25 in back. the only problem was finding a 1 inch wide 26" diameter tire. and it was necessary in that the front fork would not take anything wider.

and i think you will be pleasantly surprised by the difference it makes on the road.

I've run 1.25" slicks on a mtn bike.
It feels like a whole different bike, especially on corners!

Yes it makes a big difference. You'll really enjoy the change. Now you get to post a thread over what is the best slick tire to buy and read a bunch of people disagree on this,
