I will say one thing about Calvin, he does know all the tire regulation BS. Saying that one only has to use common sense when replacing their tires. If a person has 6000 pound axles and puts tires on to cover that axle rating and is not overloaded on tire spec I would say they have no worries.
It does seem that these tire threads get way out of whack when people start talking about replacing tires, especially in a case like this one-replacing tires with lesser ones than what the "placard" says.
One question that I have is does anyone know of anybody`s mothers`-uncles`-friends`-niece who actually was ticketed for using non placard tires that covered the axle rating-99.9 percent probably not.
Common sense goes a long ways, but some people need everything spelled out for them.

OK, lets use some common sense. In a perfect setting, a 3042# tire will work well on 6ooo# axles. Using air pressure in a balloon cannot be adequately controller. Hence, recommendations in place of positives. A perfect setting cannot be achieved.

Lets take an example. I’ll use my trailer because I know what it weighs - most of the time. It has a GVWR of 14,100# and two GAWRs of 6000#. When traveling full time our axle loads when weighed and balanced averaged somewhere between 11,500 - 11,700 lbs all the time. With a tire pressure gauge having a +/- factor of 5 psi those 3042# tires could possibly be down to 2910# each. Because I always had one axle or both on one side a little heaver than the other I would really be stressing out those tires load capacity at any speed.

RV trailer manufacturers are often remiss in providing OE tires with sufficient load capacity reserve, sometimes almost zero. So, when it comes time for tire replacements, owners should always insure they provide at least 12 - 15% in load capacity reserves above the vehicle’s total GAWR. If you cannot do that, at least follow the industry standards for sticking with the load capacity you already have.
