Yanmar Tractor Tires
What do all of these numbers mean?
There are a couple ways that you will see tire sizes listed.
1- If the style looks like this- 9.5-22 Then 9.5 is the width of the tire in inches. The 22 is the diameter of the rim that the tire will go on. So.. if you have a 22" rim- you can put a 8.3-22, a 9.5-22, and even a 10-22 on the same rim without any problems. You can almost always put on a tire that is a little wider or narrower than the rim.
2- If the style looks like 200/50/18 then the 200 is the width of the tire in millimeters. The 50 is the aspect ratio. This means that the tire is 50% as tall as it is wide = 100mm The 18 is the rim diameter in inches
Can I put on a bigger tire?
