I would like to install bigger tire, will it fit on my rim? Ebay shows tires 700c x 25c, 28c,32c

Anything up to 28mm will work. See chart in link below:

The only other limiting factor is the clearance between your chain stays. You should have at least 3mm clearance on each side so you don't rub when the frame flexes on hill climbs.

Personally, with that rim, I'd go up to a 32mm tire.
I'm a tad conservative.

My Airborne came with 700-23s; I've had 32s on for many years and much prefer them. And I'm not even a bit conservative!

It all depends on frame clearance. I would go with the widest tire I can fit but not knowing the bike or anything else it is a hard thing to figure.

In terms of tires I probably would go for a tire from a authorized seller and generally Continental, Schwalbe, Maxxis, Vittoria, Challenge, Specialized...They way I have a warranty and can get support if I need it and know it is a legit tire.

We used to run 26x2.5" mt. bike tires on 19mm wide rims at 25psi, never rolled one off. Your limit is not the rim, its clearance, chainstays, F fork as well as what can you squeeze past the brakes. I'd try for 32mm's and if not size down to 28.

14mm rims?

DiabloScott

Also consider under the brakes - wider tires are also higher.

I put 32's on 12 14mm rims once (Weinmann DP18) and they were squirmy as hell around corners. I propose 28mm tires - that's what I've got on those wheels now and they're great... maybe 30 if you're a risk taker (and it'll fit). But I built up another set of wheels that can handle 35's and I do prefer those for commuting.

*Edit - my rims are labeled as 12mm wide so 30's should be fine on 14s.

sweeks

To be honest, I don't know. I'll have to measure them. They're not terribly wide, though; they were narrower than the 23mm tires I originally had.

sweeks

Pursuant to your earlier question, no. The rims are 21mm wide at the brake tracks. Assuming a 1.5mm thick rim sidewall, that makes it a 17mm rim. So maybe not so crazy to carry a 32mm tire.
On my folding bike, I have 17mm rims wearing 40mm tires with no problems related to the performance of the tires (depending on the brand of rim).

HillRider

That's what Weinmann's label on the rim says; "ETRTO 622x14". It is a somewhat unusual number but I assume they know what they made.

DiabloScott

Apparently ETRTO allows rounding to eliminate decimals. The Weinmann specs say 13.6 inner width and 19 outer. Not that big of a deal, but the safety margin is less than you might expect when using those charts of recommended and "maybe OK" tire widths.

Size: 700C

• Brand: Weinmann
• Model: LP18
• ISO: 622
• Width ID: 13.6
• Width OD: 19
• Profile: 16.5

Any width tire will mount on that rim. But as recently as 2014 some popular road bike brands had no seat tube or fork clearance for anything larger than 23s.

I have an older mountain bike which came with 17mm rims with 2.1 inch tires (53mm). I have yet to die a fiery death.

In addition to the above DT Swiss tire-rim compatibility chart, Sheldon Brown's site offers this chart, see 3/4 way down the page:

You'll have to interpolate between 13 and 15mm interior rim widths, but seems like 28 tires are no problem. See the note at the bottom of the chart mentioning its recommendations are conservative.

That’s way too conservative. I run 2.3” (58mm) tires on mountain bike rims that are 17mm wide. That’s a ratio of 3.4. For a 14mm rim, it should be possible to run at least a 47mm tire and probably wider. I regularly run 35mm tires on 14mm wide Deep Vs on my touring bike.

That’s a far more important parameter to consider. I do have a fast bike that can’t run anything wider than 25mm tires. 28mm tires rub on the front derailer clamp. Plenty of room between the chainstays but the chainstays are really short.

You'll likely rub the frame or something with the tread or sidewall of your tire before you get to a size that is considered unsafe for the rim. So put what ever you want to try on it. I have in the past had tires that were too big when inflated to get through the rim brake pads without deflating the tire. But that was long ago with cheaper rim brakes that didn't have the quick release to open them.

So just look everywhere on your bike and find the closest points the tires comes to on it. Measure it, multiply by 2 and that's about how much bigger you can go. But I'd suggest not multiplying it so you leave half that distance open as a safety margin for sticks and mud that might get trapped or on your tires.

And the tire diameter grows also as you increase width by roughly the same amount. So watch your seat tube, fork crown and other places tread can touch.

Additionally, tire widths are just nominal and vary from one model of tire to the next. So 28 mm tire of one model might not be quite the same width on your rim as 28 mm of another model.

This prompted me to measure my mountain bike rims. With tires mounted, they're 23mm at the brake tracks, so probably a 20mm rim internal width. Tires are 53mm by caliper, so my tire/rim disparity isn't as "extreme" as yours, but like you I have never had any untoward tire behavior. (FTR, this bike and its rider finished the Ore-to-Shore mountain bike race in 2001.)
