Question:
What does each number on the following tire size represent? 5.70 - 8
asked by: Ward S
Expert Reply:
In regards to a 5.70-8 tire, the 5.70 represents the width of the tire which is 5.7" wide and the 8 represents the diameter of the wheel the tire is designed to fit which is 8" diameter. If you are needing a replacement, the Kenda K353 Bias Trailer Tire is what I recommend and is offered in a load range B part # AM10010, load range c part # AM10012, and load range d part # AM10013.
Assuming you have clearance, there are a few other options for tire sizes that will fit an 8" diameter which I have attached a list of for you below.
