Tires Sizing Mania

[BrendonV 0]

There is pretty much only 2 things mechanically that stump me--exhaust systems for vehicles, and tire sizing, well three--i dont touch electrical stuff. Im looking to get some tri ribs for 2 maybe 3 of my tractors. The tire sizes on them now are 1-B-10 with 6.5x8, 1-B-10 with 4.80x8, and a Big-Ten with 500x8. The B-10 with the 4.80x8 are the skinnyest, and i like the looks of skinny tires especially the tri-ribs. Could someone school me on what size i need. There is just to much variation between my three tractors. Should i be buying the 3.50x8, 4.00x8, or 4.80x8. They are going on 5" wide rims BTW.

The first number is the width of the tire. The second number is the diameter of the wheel. 6.5 X 8 = 6½" wide on a 8" wheel.
