Want to stay stock with 13" tires, but can't get them

700 13 is 185 75 13. Put whatever you want on it. I don't understand all the futz. Just pick one that's the right diameter and fly with it.

Thanks for the chart.

It was difficult to find the stock size and I guess I was wondering if anyone on here was trying to stay stock like I was, and had some experience with this.

I did find some tires for it though and should be good to go!
