I'm thinking that by putting 19.5's on the truck it would add to the CGVW. I am going to check that out. Billy D.
Say what?
The chassis manufacturer or final builder has the responsibility of certifying allowable weights for your vehicle that should be on the drivers door frame with suggested tire size for that rating. If you intentionally undersize a tire, a DOT inspector could use the lower rating based on the lower rated tire. But you cannot legally increase the manufacturer rating by going to a larger tire. The chassis weight rating is based on many items that become part of a system such as rims, brakes, hubs, frame rails, springs, etc, not just the tires.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
