I need to replace the tires on my bike.
The code on the tires reads 700x38C
The problem is that I am finding tires with only 700x38 - no C at the end.
And in most models of tires (such as on sites like Nashbar) 700x38 's are hard to find. 700x32, 700x36 are more common.
Must I stick with exactly 700x38C?
Thanks
