Umm..The tire will be skinnier!!

It will also shrink the outer circumferance since your not changing the aspect ratio, therefore the wheel will turn slightly faster for the same speed and provide slightly less contact patch.

You'll wind up with a lower load rating on the front tire as well.

I just previously have run Metz's ME33 on the front in a 3.25X19. tended to make front a bit less counter steering pressure in corners. They worked well, only thing I noticed after going to a 100-90X19 (which makes it rock steady and predictable) was the previous size acted a bit "funny" if coming into a corner a bit hotter than you were expecting, likely forces and load affected the handling a bit.

Hi Ryan,
Clymer's sez the stock tire is 3.5-19 and 3.5" = 88.9mm so your 90/90-19 front tire is the same width as the original but 10% less tall.
The "inch" series tires were 100%, (width = height) while 90 series metric tires are (you guessed it!) only 90% as tall as they are wide so to keep the same OD the metric tire has to be 100mm wide to get the 90mm height.
But WTF, it's a freebie, fling it on and be happy.
