My GSX1100G is ready for a front. It calls for a 110/80/18. I have two new 100/80/18's in the garage, A Pirelli & a Continental. If I put one of these 100/80/18's on my bike, will I notice any difference? I know the book calls for a 110, & many folks don't like to deviate, at all, from the book, but my question is will I even know it's a 100/80/18 if I didn't read the #'s stamped on the sidewall? Thanks

100/80/18 vs 110/80/18 front

The problem is that a narrower tire on a wider rim neccessarily has to flatten itself a bit.
ADD TO THAT more:
the actual measure of the tire size you want to use means 80 mm "high" if it were on a rim it's intended for..... more room under the fender I guess. The original would be 88mm high...
But combine this flattening to the already slightly squashed tire and... well...
Possibly relevant notes I have about putting Lower profile tires on indicate it's a little scary to me: paraphrased , they are ok for very experienced users . They have better grip until they lose it, when they lose it QUICKLY. A rounder tire is more forgiving. I can sort of imagine this pretty easily...tires are great on the straight-ahead but curve quickly towards the sidewalls so when you are leaning round a corner it's on a very sharp radius.
If I'm right, I don't think it'd be worth the saving. On a motorcycle the tires are very, very important...Save $ somewhere else. Or, go very, very carefully....
Add: I'd guess it'd be about a 12% "difference" in "feel" as per noticing it. Not so much really but It's where and when you might notice it that sets off the nervous nellies like me. Tennessee has hills? lots of curves?

1. the narrower tire will steer quicker
2. the narrower tire is also shorter, and will increase the speedo reading
3. the narrower tire will have a lower weight rating
Are your two tires in the garage really "new"? They may have been recently purchased, but check the date codes.
I would not intentionally buy a smaller tire than specified, but if you already have the smaller tire and nothing else to use it on, go ahead.

you will want a little more air in them than what you are putting in the originals, I think.
