Does anyone know the load carrying specs on the 22" inch tires vs the 19.5" tires? I'm sure the chassis specs are the same but I would suspect the 22" tires would allow more cargo weight before you max out?
If nothing else I would think the 22" tires would ride better.
Would the increased height require one more step to get into the coach?
A lot of questions but it is such a new option I'm very curious about it and have no way to get any practical info about it.
Increasing the diameter of tires does not change the max weight capability of the chassis. If a 22,000 lb chassis has 19.5" tires or 22.5" tires, it is still a 22,000 lb chassis. Generally the taller the tire (higher aspect ratio) the better the ride, but worse the handling because of tire squirm. The larger diameter tire (not the rim size) will usually give more tread life. Remember it is the air in the tire carcass that holds the coach up. You can achieve the correct amount air by high pressure in a smaller volume tire or by a low pressure in a large volume tire.
