Front axle weight rating and legal weights I can scale?

You are allowed 20,000 on a single axle in most places.

I have a 20k steer and 20k steerable tag that both sit around 18,500 lb just driving around. My only issue that I have to be permitted for is being 37k empty on my drives, even with 52k rear ends.

 

If your axle is rated at 13200 and if you have H rated steer tires then you’d be legal with that weight on your steer. If your steer tires are G rated you would be overweight on your steers.

 

Your tires will tell you your weight rating.

If they match your 13,200 rated steer axle. You're golden.

12k is just a basic number to go with 34+34. NOT the rule.

Some states however. Might have their own say. Like Oregon.

 

Don’t just go by the letter identifier; physically read the tire’s rated weight capacity.

Also, look into the motorcoach side of tire brands. You might find higher rated stuff, there, that isn’t listed on the commercial truck side.

 

You can go over 12k on the steer in OR without issue.

 

If I’m not mistaken, steer axle weight rules are different, between ‘tractor’ and ‘truck’.

 

I didn’t even think about the variety of RV memberships out there. You’ve stumbled onto a great idea! Haha.

What made me think about motorcoaches was weight carrying capacity. In talking to several coach owners, over the years, they’ve repeatedly mentioned how heavy the front of a coach is and about how susceptible they are to blowouts. In researching tires, I’ve noticed some manufacturers have motorcoach-specific tire sections. Presumably, I’m thinking there might be some really heavy duty options available, without ever having looked. Not sure.
