The (first) last time I replaced my front tire i accidently ordered a 110-90-19.  I got it mounted on the wheel, then found out my fender was too small!  I ended up raising the fender about 1.5 " with brackets made of 1/8 steel.  I ran it that way for about ?? 12K ??  Didn't really notice much of a difference going to the larger tire at that time.  

It was time to replace again, I went back to the 100-90-19 (same model- Kenda Challenger).  First ride was this AM-

I was surprised- handling was considerably improved with the stock size tire.  I really noticed it when hitting curves fairly hard.  It feels a lot more stable.  (Not much difference going straight, maybe a little easier to start into turn from going straight)

Maybe my fender bracket allowed a little more flex than just the fender?  3-4 years ago when i switched it maybe i just didn't curve as hard?  

(I do think it looked a little better with the bigger tire and higher fender)

Next time, try a 2.75 or 3.00-19, in conjunction with a 130 rear... you'll scare yourself with how much faster the bike turns... and the 130/?-15 rear is for a Honda super scooter (Pacific Coast), serious life span on our bikes.

Tried that combo on Max Morley's advice years ago... turns your "Slopoki Salvage" into a decent handling machine...  

It is tricky to find a long lasting tire in skinny 19 inch though...

Isn't that bike, nicknamed the Flying Urinal?... ...
