Tire/rim size help?

Hi,

This is probably a simple question!

I just want to check what tire size my rims can support? The rim size is 559x17 and looking at the pic (attached) i think its telling me it can handle a width between 1.5 and 2.1 inches?

Im looking for a new tire but want to get the thinnest slick for my city riding.


Thanks in advance!

The "559" is the bead seat diameter, basically the diameter of where the tire seats on the rim. 559mm is the "26er" size, like what's used on older mountain bikes.
The "17" is the width of the channel in the rim.

The graphic appears to be stating maximum permissible tire pressures for different widths.

A 17mm channel is often used on road wheels for bikes with 1" tires; those rims can probably handle just about any non-super-wide 26er road tire just fine.

You can probably get away with a tire as narrow as 23mm, but...but...the rim may not like the pressure that you'll need for it. So one issue is whether the tire will mount and stay on the rim. Another is whether the high pressure will crack the rim in the medium-, long-term.

Try something like this:

http://www.nashbar.com/webapp/wcs/stores/servlet/mProduct4_10052_10053_175439_-1_catNav

At 26*1.25 or 559*32, it's thinner than most 26" tires, should be a nice smooth and fast ride if you're all paved and hard packed. Stay below the 80 psi on the rim sticker.

I ride 27*1 1/4 on my main bike.
