Bicycle Mechanics - How wide of a tire can I squeeze on my rims?

I have an AKX R1.0 rim, sized at 622x14. Currently my tires are 700x26C, but I want wider. I've recently sold my car and using my bike as my primary means of transportation, so I need more ruggedness as I hop on and off sidewalks.

It appears I have sufficient room in the forks for larger tires, and I'm hoping to not have to buy new rims.

If there is additional info needed to know the answer, just let me know and I'll provide it.

Thanks!

What bike is it?

It's a Fuji Silhouette. Not sure of the year, but I bought it around 2002 and it was new.

Try some 700 X 35 tires

There are no absolute rules, but staying within a decent width ratio helps.

Here's a link to a tire/rim ratio chart (http://www.bicycletires.com/a_49/tire_width/article.htm) that might help. Remember you're comparing nominal tire width to inside rim width, so allow for the wall thickness if measuring the outside.

I find that going wider than the norm on tires is OK, but if you have cantilever brakes there might be issues with the swing clearance on the brake shoes. Also don't forget that fork clearance is the ultimate arbiter of how wide you can go.

The max width that you frame will take will be more important than the width that the rim will take, looking at Bikpedia there was a 2003 model made, this is a hybrid, and would be supprised if you can get more than a 28c tire in the frame.

If you are looking at hopping on & off the sidewalk with this bike, would be more concerned about the frame and other parts failing, this is effectivly a road bike with flat bars; get a trials bike or MTB if you want to do that.

Usually the frame/fork is the limiting factor. I've never actually had a problem mounting wide tires on narrow rims. Measure your frame and fork where the tire sits and get an estimate of how wide you can go.

Something like 700x35s would be totally fine on your rims.

Thanks for the help. everyone.

My fork is pretty wide, I measured 49mm at the point near the widest part of the tires. Height looks like similar clearance. I'm assuming that means I'll be fine with some 700x35's, so let me know if I'm missing something. Planning to hitch a ride to the bike store shortly.

Let us know how it turns out.
Have Fun.

Just wanted to follow up and say that I got some 700x35C's and they fit great. Thanks everyone for the help.
