Tire help

[buck_n_duck]

Is there anything wrong with going overboard on load range rating? My trailer came with load range d tires. I had a blowout within 1 year of just being a weekend warrior. Thinking of going to a load range F.

How much weight is on your tires?

I plan on going to 16” rim.

Trailers unlike our trucks can be over tired.
My '97 11400 lb gross weight 5er with 5200 lb axles came with ST225/75-15 D at 2580 lbs capacity. Trailer had 9200 (+/- 100 lbs) lbs on the axles depending on how we loaded it.
I upgraded to 16" trailer wheels and BFG Commercial T/A2 LT215/85-16 E at 2680 lbs capacity. Ran the 1st set for 7 years and 55k miles...2nd set for 50k miles and 6 years. No issues.
Going with a LT tire will give you two top choices in a commercial grade all steel ply carcass tire.
Bridgestone R-250
Michelin XPS Rib

And several good poly carcass LT tires used on trailers like the ...
Goodyear Wrangler HT
Cooper HT-3
BFG Commercial T/A 2
Firestone Transforce

All tires above have been recommended by their mfg for trailer use.

Most truck stops have a CAT scale. For something like $12, they are happy to let you weigh your rig.

For an extra $2.50, you can drop the trailer and weigh the truck separately if you do it at the same time.

This gives you all your weight info (well not side to side but close enough).

Now you know the real load on your trailer wheels.

I was exactly where you are last year. I upgraded to Endurance 225/75/R15 load rate E and love them. Weigh your camper loaded and adjust air pressure to the chart. I air mine to 68lbs.

No need to change rims unless you just want to.

If your asking what your rim is rated for... pull it off and check the inside of the wheel ( opposite side of air valve)... it will be stamped..

IF you crawl under the camper with an flashlight, you may be able to see it there without removing

I plan on buying rims rated for PSI on tires I am buying.

I quoted wrong one earlier talking about PSI for tires.

If you have 6 lug wheels you can put on 16” and use LT Es 3042 lbs. BTDT on 3 of my rvs and that was the end of the ST tire problems plus you’ll have tires built to much higher passenger carrying specs. Craig

Lots of opinions on over tiring your trailer! IMO...it is unwise to way over tire! Going up one load range is normally okay, but I then recommend running that tire at full sidewall pressure, to gain any advantage. If you have been running Ds at 65 psi, and keeping within the tire wt rating, I would not go to F rated, and not run max pressure. If you feel the need for more wt capacity, I'd go to an E-rated tire, and run the full 80 psi. If your wheels have Ds from the factory, the wheels are likely rated to 80 psi. The F rated tires likely rated to 95 psi may not work with your wheels at full tire pressure. Sure you could run the Fs at 80 psi, but to what advantage, and may make them run hotter.
