    Posted: 20 Mar 2017 at 3:21pm
I just bought a set of goodyear 520/85R42 tires for the 7080. Got them cheap at an auction. The goodyear site says they will go on a 16" rim. From what I can tell these are the same as a 20.8 tire width. I have only used those on an 18" rim. Has anyone here installed these on the 16" rim? I just don't want to have to mount them a second time.

If there ultra torque 16" is the recommended rim width. Dyna Torque recommend an 18" wide rim. It depends on which series tire it is. Go to the Titian site and look up your exact tire.

The rim table I have on this computer extracted from a Titan Ag Tire Handbook says the preferred rim for the 520/85R42 is a W16A. Then the approved rim list is W16A, W18A, DW18A,  DW16A, DD16, DD18. So 18" rims are acceptable. That chart is way in the back of the Titan/Goodyear Ag Tire Handbook.

They are the ultra torque. 16 just seems narrow to me. Thank you for the responses.
