you aren't below average silly, you just need a NEW BIKE - KIDDING
okay I did some research, Terry makes a 650C in 28mm. Not finding any 650C in a 25. TELLUS TT TIRE 650 X 28C (28-571)by terry MSRP is $45.
To determine if they would fit, measure the clearance (where your tire goes thru the frame) Look at your existing tires and see how much room you have
on the front fork and two spots on the frame on the rear (where the tire passes thru) The bike hermit is thinking you'd want to have 32 mm at bare minimum to fit a 28 mm.
Typically tires will measure slightly smaller than stated - around 26 mm as opposed to 28 mm.
Hope that helps, how frustrating to be limited to only a 23mm.
Thanks Sky, I'll measure for clearance.
EDIT: nope, not going to fit
