Re: wheel bearing sizes
Wheel bearings have little to do with tire/wheel size but more with axle capacity. Unless you know that or take the wheel off, remove the bearings and actually look at them, you don't know what you have. A straight spindle axle can have one of two bearing sizes. 1 inch inner and outer, or 1-1/16 inch inner and outer. 1-1/16 being common on 1500 - 2000# axles. Axles rated at 3000 - 3500# have 1-1/16 outer and 1-3/8 inner (not 1-3/16 inch).
Here is a chart with the industry part numbers
