I noticed this is your first post. You will see a lot of discussion about tires especially in the summer when the weather gets hot. Standard ST tires are not heavy enough for a Montana Camper and barely for a High Country. My advice would be to get rid of your present tires and get a set of H rated tires before you have a blowout that does thousands of dollars damage like we have seen so many times on MOC.

Agree with mIL get rid of the junk Rainier tires is the first thing you want to do! And get the alignment checked.

Look at your spring shackles closely. Make sure one of the ones for that tire has not gotten flipped accidentally. It does happen and is an easy fix get it to flip back to normal.

Unfortunately, your rig only comes with 6,000 lb axles, and you may have F range tires. The wheels are only 6 lug, so my recommendation would be, put on a set of Sailuns, inflate them to the max that the wheels will allow, which is probably 95 psi, and you will be good.

Looking at the brochures for the 2017 and 2018 Montanas the 2017's all have 8 lug wheels and G rated tires. The 2018 brochure is hard to see all the models but the specs all have 8 lug wheels and 110# pressure rating.

I can't speak for the 2018 HC's but our '19 did indeed come with 8 lug wheels rated for 110psi and G range tires. However, Keystone opted to put more money in their pockets by installing a cheap china bomb F range tire on those wheels.
I'll be replacing the F range Rainiers after this season as well. Surely (hopefully) we can get one season out of these things. They did come with a 5 year warranty but based on past china bombs, I have no faith in them.

My 2017 HC ARRIVED with 8 lug 110# wheels. The Rainer LR F tires went from the dealer to the tire shop, 43 miles, where they were replaced with Sailun 235/85 LR G tires with a 4400# rating.

Your are starting to have tread separation causing the uneven wear. Total failure is not far away. Blowout imminent. Get those ST tiress off of that RV ASAP and install LT tires and your troubles will be gone. ST Tires are junk.

If you have the 8 lug wheels ~~ Sailun 235/80/16 (not 235/85) at 110 PSI. If not do as suggested above, same Sailun tire at 95 PSI. My 2017 370 BR arrived with the 110 psi wheels and Rainer tires.
It may not be the tire at fault causing the wear. It could be alignment or suspension problems. Even a bent spindle from hitting a pothole. Still, get the Sailuns!

If it walks like a duck, talks like a duck, looks like a duck it IS a DUCK.

Could be with ducks. Neighbor had driver side rear tire wear and no others. Whoops an axel problem. Sailun 235/80 have a 4080# rating and OP will have plenty of cushion, I run 235/85 rated at 4400# per tire and way over required.

I had severe tread wear equally on the inner and outer edges of one tire. The center tread was good. Turned out to be the spindle nut wasn't tightened properly by the tech that did the bearing re-pack. Had to buy a new G614. Now I jack each wheel after bearing re-packs. Found a loose wheel after the next bearing job. About 1/4 inch wabble at the tread.

Thanks MLH
Just got our Monty 3750fl in mid January and as part of the deal I requested a new set of OEM rated tires.
Just looked at them and I now have a set of Goodyear Endurance ST235/80R16's with 18 miles on them for sale if ya know anybody!

Geez, the OP asked about one of his four tires wearing badly, not about tire ratings and recommendations. To the OP, it could be bad bearings, a dragging brake, a bent spindle or misaligned axle, or something loose under there. Ask the dealer to align it after the repair.

Not all High Country's have the same axles. The 305RL is one of the lighter rigs and comes with 6,000 lb axles, and likely those axles will come with 6 lug wheels and F range tires. This is the link to the 2018 HC spec page, and under Towing Features, you will see which rigs have 6,000 lb axles and which have 7,000 axles. https://www.keystonerv.com/fifth-whe...tures-options/
