Widest tyre I can fit

[flash]

What's the widest tyres I could fit to a 26" rim, external rim width 24mm, Internal width 18mm.
Ta....

About 3.5x is the maximum. Much above 2.3-2.5" is going to start being trouble. Usually frame clearance is the limiting factor though.

Woah there - 2.5 on a sub20mm internal rim - SQUIRREL CITY.

I would be VERY Cautious about doing anything other than a slow trip to the shops on a 2.5 on an 18mm internal rim. I push it by putting 2.35 but even that can be a scary ride on roots descents and fast berms. Max 2.20 in my view.

This is going on a sort of road bike...

I can't see the point on a road-use bike...even on the tourer 1.5" is great but 2.0 slicks are too draggy.

It’s a weird project... I ride big tyres on most of my mountain bikes. They provide a nice comfy ride. I’ve narrow tyred bikes if I want to cover more miles..

Re:

You can fit as wide as will fit as long as you accept the handling compromises and fill them with enough air. I have fitted 26 X 3.0 before but pump them very hard otherwise handling is awful and tyres can roll off beads when cornering.

Re: Re:

I think in many cases though , that the bead seating would be too odd an angle there would be a risk of it coming off.
