Would a 25mm tyre fit? pictures included

Hello!

Need a bit of help verifying if a 25mm would fit my wheel/frame, currently running a set f 23s. I can't just run to the store and try one on, I live in a small town with very limited cycling gear. I'll be ordering them through wiggle/amazon.

Wheel model:

Rear:

Front:

I read about the 25s being more comfortable, faster...etc and I'm in for new tyres, so I thought why not ask and see.

Any help is greatly appreciated! Thank you.

PS: Excuse the dirty bike, been a while...

You might be able to fit a 28mm in there. 23->25 is only 1mm extra on each side, and you look like you have a lot more room. The tightest point looks to be the rear brake mount area. Also looks like there's a cobweb in there.

I think you look a little tight on the rear. It should be fine on the front.

How fast do you wear through tires? 1 year? A few years?

I'd order a tire for the front. But, first mount it in the rear and see if it fits. Then, if it is too tight, just use 25mm in the front and 23mm in the rear. If you burn through tires pretty quickly, you could buy a pair, then if it doesn't fit, just keep the second tire for the front (keeping mind that the tires last about twice as long on the front).

If is also possible that once you get a few thousand miles on the tire, you'll be able to move it from the front to the rear.

Some tires run a bit large such as the Schwalbe Marathons. It might fit on the front, but I wouldn't try it on the rear.

I'm also seeing a couple of tires listed as 700x24
S-Works Turbo 700x24c
Continental GP Force II Folding Tyre 700x24mm
I haven't tried either of them, but they might be worth considering for the rear (or buy one and try it on the rear, otherwise put it on the front).

Haha! I did not see that, cheers for the laugh. As well as the advice.

Taking a pic seemed faster/easier. It's just an iphone 4s. :/

A year seems about right. The ones I have now are starting to show wear, plus the front got a tear on the side from hitting a nasty pothole.

Thanks everyone, I'll go ahead and put the order in.

if You measure You need not even post and ask Lazy question.

Buy from a local shop & if they don't fit you give them back on The spot. & get something that does .

Quite simple really. I don't have a ruler. I even stated on my OP that I can't just run to the store and pick one up, tried that with 3 stores, all they got are 7$ 23 noname tyres.

Got allen wrenches? If so, you have feeler gauges that can be used to tell whether a tire 2mm taller and 1mm extra on each side will clear the various parts of your bike.

Brilliant!

Now how standard are these manufacturers' sizes out of curiosity? I mean seems like 28mm should equal 28mm regardless of brand, but just making sure tires are not like pants!

Tires are very much like pants in that you can't always trust the labelled size. But you can add whatever margin to those measurements you want in order to feel more comfortable in ordering tires.



EDIT: Took so long composing this post that @Seattle Forrest beat me to it!

I vote ordering one (eg. on Amazon), and if it doesn't, return it.

I have 1 brand 23 that's exactly the same as another 25 once mounted & pumped.

Go here Tire Sizing Systems and scroll down until you come to Width Considerations and then you will know exactly what width is safe for any rim regardless of the diameter.

Outdated and not necessarily correct. Eg.. take some now popular rims... eg HED Ardennes+ with a 21mm internal rim width. Per Sheldon's chart, you're not in the range unless you mount a minimum 35mm tire. Nonsense.
