Looks like you may have sufficient clearance on the fork, looks tight on the chainstays though from the two photo's in your post. Also different brands can size up under/over 28mm so if you are referring to clincer tyres I'd buy from somewhere that offers free returns or use a friendly LBS that will let you do a trial fit on a sale/swop basis.0

I'm going to say no. They may just about physically fit - but you will have no clearance and will be forever grinding stones, grit, etc against your stays.0

Second that, but you could try a michelin pro4 in a 25mm they come up big, but not quite a 28.0 -
I'd agree ^ - looks just too tight on the back tyre.
Don't get overly obsessed with the sizing - a 28mm Conti GP 4 Season is of very similar width to a 25mm Conti GP4000S ii (no I don't understand really either - there are those that say the measurement on the tyre is more to do with height and whilst width is related to height slightly, it is possible to have a narrow, tall tyre).0 -
Cheers for the info and help guys I went on chain reaction and got a cheap set of conti ultra sport 2 in 28 so if they don't fit then I can send them back and didn't cost me a arm and a legWhen i die I just hope the wife doesn't sell my stuff for what I told her I paid for it other wise someone will be getting a mega deal!!!

Ride through any mud / wet grit, it will stick to the tyre and build-up under the frame and can actually jam the wheel.Make mine an Italian, with Campagnolo on the side..0

Or worse, you'll ruin your frame.Advocate of disc brakes.0

Why?
I already explained why in my earlier reply. Or just read Monty's reply above.0 -
I've seen people running less clearance, mostly fixie fashionistas. You're prolly just going to get sick of the sound of scraping leaves continually wedging themselves in there.0

As if thats going to happen in winter 8)
I would have thought sticking some better quality 25mm tyres on for the winter would be a better option.
Grip and ride quality is more important than extra comfort isn't it?
Bikes liable to get damaged by stuff rubbing frame or even coming off due to choosing comfort (Are 25mm not comfortable enough?) over grip.
A winter bike would be the best option though.
The best thing about which is riding along thinking about your best bike safe/dry in the garage, and knowing you don't have to spend ages washing it when you get home.0 -
Actually thinking about it, whilst it's unlikely, getting a nail in there will be carbon carnage. I got a nail in a tyre last year (once in 5 years, unlikely but happens) and with no clearance on the mud-guard it got shredded.0
-
Not only carbon carnage, but a good chance wheel would skid/lock and you would be on the deck!
Also, once in 5 years could be tomorrow, then again in 5 years time.0 -
As wheels get older they can begin to wobble. Not just visibly from side to side but in its roundness. If this were to happen even slightly you are going to start hitting the frame. It will be so gradual you wouldn't even notic until its already starting to remove paint. For the sake of a few mm tyre width its not worth it. Especially on such a lovely crafted frame.0
-
Here is what happened to my front fork from a 25mm tyre on one of my bikes. The fork clearance will take 28mm supposedly but it goes to show the slight error in the wheel/tyre or even debris as mentioned can rub and cause damage.0
-
Cycled 7 miles to work and all was fine even on Portland Dorset where it's basics grit and mud at the moment good job the tyres wer only £8 each so will prob just go back to 25. Least I no I can squeeze a 28 on thereWhen i die I just hope the wife doesn't sell my stuff for what I told her I paid for it other wise someone will be getting a mega deal!!!
