New tire help...

[nhcop]

So its about time for a new set of tires.

I am finding it hard to get a front tire in the right size 110/90/16. Currently I have a 100/90/16 on the front rather than the 110 that it came stock with. The 100/90/16 was on it when I got it.

I am thinking about ordering some Kenda Cruisers 130/90/15 and 100/90/16. (they dont come in 110/90/16)


So some questions....
1. What do they put on the GZ from the factory???

2. I have been running the 100/90/16 on front and it seems okay, but is it a good idea to go with that size again, or will the bike perform better with a 110/90/16?

Thanks
