The basic difference is that the first tire's width is 3.25".
The second tires width is 100mm, which equals 3.94" wide.

The second number for each tire is the sidewall height aspect ratio.

The third number is the wheel diameter.

Yea, it should fit, if you want a cheap, really skinny, bicycle tire up front.
But I would check the manufactures tire specs for max rim width.

No.........
Only the "C" models carry the 90mm 21" tire.
