Hey Randy, I would find out the metric numbers from the tire.  Then you can see the relation between the height and the width, and maybe compare it to other tires.

I have found that only the big name brand tires are actually labeled correctly as for size, the lesser brands are all over the map. In my opinion, the Chen Shings are not good performing tires. I have found some "small" Maxxis tires that work well. Interesting fact: usually the lesser brands are heavier, even if a bit undersized!! Even though your bike is a 'vintage' 125, you may want to go with a Dunlop or Bridgestone full size 125/250F tire, they are light and perform the best.

Vee Rubber, VRM109's They are from the same molds as the old Dunlop Sports. I've been running them on several of my vintage race bikes the past two seasons. Not only do they look period correct, they are a great compound. They work well in a wide variety of contitions
