"In regard to your question about wheel width, a 6.5” wheel is recommended, however; the 6.0” and 7.0” wheel width is allowable. There is no risk around the safety of the tire in your application.
There could be a minimal effect on the wear on the outside rib of the tire. The narrower wheel “pulls” the beads of the tire in slightly. This can cause the footprint of the tire to not sit completely flat on the road (shoulders slightly raised off the road). The result is possible irregular wear on the shoulder. This situation is compounded if the inflation pressure is higher than the recommended pressure. It sounds like you have a pretty good handle on your inflation if you are following the chart. Just keep an eye on the shoulder wear. If you see irregular wear start to develop, you may be able to lower the pressure slightly if you have 10 psi of safety built in. Don’t go below the recommended pressure though."
