Tire size for rim question
#1
Bought a Fulcrum Racing 5 wheelset and immediately put 622-28 Continental Ultragatorskin tires on. No problems with the tire installation, a bit of a struggle to get on but not unusual, and they look fine.

However recently went onto the Fulcrum website and downloaded their owners manual pdf. Discovered that they recommend 23 - 25 mm tires for the rims. The rim is rated ETRTO size: 622x15C. (This size rim in say Mavic Kysrium elite is compatible with 19-28mm diameter tires.)

So question - what is likely to happen if I leave the the 28 tires on the rims? They seem to fit ok. Seem tight to the rim. Anyone?

I will admit that I am not much of a pro at this , but they recommend 23mm to 25mm for the wheel. You put on 28mm. If it is tight and supposedly bigger then it should be fine. Although I really have not got that far into metric sizes for tires it does sound ok. Here is a little link that may shed some light on tires for you, I use it myself. http://www.sheldonbrown.com/tires.html
Good maintenance to your Bike, can make it like the wheels are, true and smooth!

Hm, it might work out. The probability for the tyre to be stripped off the wheel when cornering fast is a bit higher than with the recommended sizes. There is probably a margin though, they usually give quite conservative estimates there (liability etc.). You went with a width that is 12% larger than recommended, keep that in mind.

I do not think that you'll have any issues.
