17.5 Wheel upgrade, or 19.5?

Considering how cheap the factory tires are on a new unit, if we're going to upgrade the 16" wheel/tire combo why not get 19.5 wheels with 14PR rubber? Same aspect ratio (overall height) just less sidewall to flex. Of course cost is an issue but a blowout can be even more expensive with trailer body repairs. I'm upgrading trailer soon adding an additional 4000 pounds of towing weight and recent forum pics of tire failures have me thinking. What say ye!

Adding 4k of trailer...I see your point. Plus water, beverages and her make up/shoes & clothes probably 5000lbs more. Wow, perhaps I should be looking at duallys for the 5th wheel!

I think the 16" G-rated Sailuns are 14-ply rated for 4,050lbs, so no need to go to bigger wheels.

That is what I have on my Heartland Bighorn at 16k Gross Weight. Run great! Hold the load well.

When I did the upgrade to 17.5” wheels, I jumped to something like 4,800 lbs of tire capacity:
“215/75R17.5 LRJ Continental HTL2 Eco-Plus radial tire rated at 4,805 pounds with a 75 mph speed rating.”

I can’t imagine that you need to consider 19.5” wheels.

I also upgraded rigs. The new camper came with the same G-rated Sailuns as mentioned above. With 3 axles and a 21k GVWR, I’m comfortably within specs on tires and don’t feel the need to upgrade to 17.5” wheels again.

Thanks for all the input, 17.5's would probably be a sufficient upgrade for an 18k 5er. I got stars in my eyes when researching BoarWheel.com. Go big or go home got in my mind and I needed your counseling to bring me back to earth.

If you upgrade to the Sailun S637 G rated 110psi tire from a E rated 80 psi tire, will the 80psi stock wheels handle the 110psi?

....and now we're back to the 19.5 discussion again. Heavy duty tires need HD wheels. Take a look at Boar's Cruiser 67 and try to talk me out of it again, please.
