The spec'd FRONT tire for my '13 650 is 110/80 19.
I am interested in the Dunlop TR91 series and although the REAR is available, all the normal ONLINE outfits are "Out of Stock" on the conforming OEM size above.
I an get a 100/90 - 19 "In Stock" which I believe is a little 'taller and narrower'. Anyone know the pros and cons of using a non specific size on the front end? :confused:

Here is a chart. Rim to Tyre Application Chart

Narrower tires in the permissible range will likely not last as long while wider tires in the permissible range will last longer but may feel vague at greater lean angles. The wheels are 2.5" in front and 4" in the rear.

The chart used to show it. I don't know why it's gone.

The 110/80 tire is 88mm high where the 100/90 tire is 90mm high, and one is 10mm wider that the other.
You might find the narrower tire to turn in a little quicker and be slightly more stable in gravel. Slightly.

So the difference between 110/80 and 100/90 is that the 100 tire is just 1cm narrower but 1 cm taller. I can live with that. Thanks for the input

1 cm narrower and 2 Millimeters taller. Way less than 1/8th of an inch.
