What size is a 285x70-17? All I can find is that it is 32.7 tall. How wide is it? Will it fit right on a 10'' wheel.

The 285 number represents the width in mm. Divide that number by 25.4 and you'll get inches. The '70' represents the sidewall height as a percentage of the width, so 70% in this case. Should fit on 10" wide wheels, but I'm not an expert so I'll defer to someone smarter than myself on that one.
