tires

Can 17/40 X 15 tires fit on 8" rims? And does the 17 represent the tread width? thanks Dave

yes the 17 is how wide they are.. And you can fit any size tire you want on any width rim. its just how hard it is to do.
It will be very hard to mash it down to fit, but you will not throw a bead and the middle part of the tire tread will be Bowed out unless you run very low PSI

Yes 17 does represent width. You could mount that on a 10" rim, but I would feel more comfortable with 12-15.

Correct. Best way to figure what you need for tire width on any wheel is to multiply width of the wheel by 1.5. With an 8" wheel the widest that you would really want to go is 12" for tires. That's why I stated 10-15, I would imagine that particular tire is quite stiff in the sidewall so the wider the wheel the less dificult it would be to mount it. When I worked in a tire shop that is the rule we went by, and would not mount tires that we felt were too wide for the wheel. Not saying you can't do it yourself at home, but I wouldn't.
