Yes another Tire Thread and another question
All,
First off, new to the club. Looking forward to gaining knowledge from everyone with years of experience.
I know there are a ton of opinions on tires and from all the research I have done I think I have it down to two selections, Wife and I just purchased a 2021 Keystone Montana 295RL (which we really like). The tires are ST235/80R 16F (12 ply).
Looking to upgrade the tires to:
Sailun ST 235/80R 16 G9 Rated/14ply (all steel)
Or
Hercules ST235/80R 16 H-901 (G rate/14 ply all steel)
Any opinions on either?
Second, could I put 85Rs on the 295RL model?
Lastly, my Black tank sensor always reads 1/2 even when drained. Any helpful hits?

What's on it now? My MHC came with Ranier LRF tires which I removed before taking possession. I had them install Sailun LRGs and have been happy. Why would you want to move to the 85 series tire?

Right now the MHC came with ST235/80R 16F
I was just wondering if I could go to a 85R

The answer to that is yes the 85's should do fine. The Hercules are good tires, but they probably will give you a rougher ride. I'd go with the Sailuns.

Yes, the 85's will fit your wheels and will only be ½" closer to your trailer floor.

Okay, another tack.
ASPECT RATIO: Often referred to as the profile or series, the aspect ratio of a tire is determined by dividing a tire’s section height by its section width when the tire is: inflated to maximum air pressure, mounted on the approved measuring rim, and under no load. A tire with a lower aspect ratio responds to lateral force more effectively.

In what way?
I've always heard that ST tires were built because they have stiffer sidewalls to reduce sway. How are the Bridgestones better?
thanks,
Brad

Tires
My understanding of st tires is they don't have to build any load reserve in them . Because their are .no people riding in a trailer. ( more profit for them ) Im in construction and own multiple trailer's i found that st tires were like bad socks they roll around your feet same with trailer's they sway to much . Why are there no st tires on class a vehicles. Just my experience with trailers.

Bridgestone does not build a 16" LT tire with enough load capacity to replace the afore mentioned ST tire.

Randall,
The black tanks gauges never work well. All it takes is a piece of TP stuck near one of the sensors and it will not read well.
Dump once a week and don't look at the black tank gauge.
I also recommend the Sailuns.

Ditto on the Sailuns. You can go to the 85's but unless there is a compelling reason to do so I'd stick with the stock size.

The compelling reason would be getting around 400lbs more weight capacity per tire. If there is room between the tires and above them, I would opt for the 85,s. They are only 1" taller

I think going to the 85s to gain the additional capacity is a bit of overkill; even the LRGs are to some extent. The OPs trailer weighs close to mine (his is a little lighter) and the LRFs that came on them met the new RVIA specs for reserve capacity. The LRGs take that further, to a very safe range IMO. When installing higher and higher capacity tires on a trailer there is a point of diminishing return, even no return.

Agreed, and there is the potential to actually increase other risks, such as creating a harsher ride, or overloading other parts of the suspension, including the wheels.
For example, most tire shops will recommend upgrading wheels to a higher load rating to match the increased load rating of the tires.
IMO, it's not as simple as it might seem, and one needs to take into account all the pieces of the puzzle, not just the tires.

I totally agree. So many folks want to improve without limits. I still have my original factory everything on both my Ram 3500 and HC 331 and all is well. I use a TPMS and visual checks at every stop. An RV can become a money pit if you want bigger and better stuff.

Actually they are only 1/2" taller. They are 1" larger in diameter.
I have the 85's because I wanted the 1/2" but they are 1" closer together so I have to invert the stabilizer X-clamps s o I can get to the nut. Also they rub on the fenders.

I stated they were one inch taller which is correct you just did the math for people stating it would raise your trailer 1/2 inch and reduce the gap between the two tires by 1 inch.
Before I have the independent suspension installed the tires would rub the fenders and the underside of the trailer. After the independent suspension install I have plenty of clearance since the trailer was raised around 5 in

The Sailuns don’t give any trouble. They are inexpensive. I can’t think of any reason to not get them.
