12000 miles time for new tires.

Do the Rainier tire have a fast wear compound?
I put about 8k miles last year & I thought the looked about 1/2 gone.
My wheels are rated for 110 psi so I'm going to go to a G rated I think & hopefully get more miles from them.

This is old data from Trail America tires, around 2008 about ST tires. Under mileage it reads ST tires are not designed to wear out. The life is limited by time and duty cycles. Mileage expectation is 5,000 to 12,000 miles.
You did not ask about age, so I will not mention their data.
I did have Goodyears ST tire booket and do not remember mileage mentioned just age. Maybe look up your brand and see if the company lists anything.

They're not old it's a 2018.
A friend of mine has a similar unit, about the same weight he's looking to get over 20K on his. I don't know the brand of his tires.

I'm curious why you want to go to a LRG. Your OE tires provide you with 750# of load capacity reserves per tire at 95 PSI. That's 25% above your axles maximum loads and 10% above the 15% most experienced posters recommend.

There are a lot of brand names building that tire in a LRF.

No one touts ST tires as being mileage tires. Most that are very high mileage users will go to commercial 17.5" trailer tires. They can be found in diameters & widths vary compatible for most RV trailers your size.

Worn out after 12K, after a year, interesting.


Regardless, if you are getting new 'G' rated tires Saliun (the 85R tires) and Goodyear G614 are the way to go. 110psi tires.


Your wheels are rated for them based on what you said.

[ChuckS]

The G rated tires may not give you much more mileage but they are head and shoulders
A better tire than your current ones. I would get the Sailun S637 and you will have much more headroom on tire weight capacity.

I think a better brand might give more mileage, maybe not.
I probably don't need the higher weight rating, when I weighed I had a little under 11500 on the trailer.

I got between 50-60k in 5 years out of the OE GY614s & replaced with the Sailuns that had close to 10k when I sold it, would highly recommend either if these.
I have no experience with Rainer tires, but may want to have alignment checked before replacing with new tires.

I just had the Morryde IS installed about 3000 miles ago, hope the alignment is good.
Could have been off before, but the tire wear seemed even, thought they seemed to be wearing like an underinflated tire more on the outside.
They have always been run to max. 95 cold

[travelin texans]

MorRyde does an alignment when they install the IS, so you should be good then.
Did you also get the disc brakes? If so aren't they 110% better than the drums, best $$ I spent on upgrades.

[77cruiser]

The whole setup is great, disc brakes are a lot smoother. The ride is way better haven't seen ant trip pieces hanging, & the sink covers have only popped out a couple times.
Only thing I didn't like is the way they put the under belly back together. I'll have to fix that. Just haven't had time yet.
