replacing tires, have 3 6000lb axles

[Vanhollymorgan]

New road warrior and out of the gate i want to get rid of the powerking tow max. the 415 when loaded is around 17500, ive got 3 6000 lb axles on it. 235/80r16 tires. I was confused about tire weight ratings. My normal travel doesnt take me more than 300 miles from home. ( we use it for a travel sofball team 10u girls....74wins-6losses right now but gotta brag)

Any way, i dont have an extra 2400 for the good year g614 right now. (Nothing like a good kidney stone to mess with your budget the day you pour money into a 5th wheel) I do want to go with a LT tire. Would the duravis or sailun not have the right load capacity? I think there is a bridgestone commercial ta tire as well.

i'll probably do the 614's in time late next year. Whats the best alternative? Just doing a tpms and keeping the china bomb.? I generally stay 60mph.

i have about $1100 to spend now, maybe a little more if the wife is happy this week

What would the masses do? LOL

...and a spare.
...or in my case two spares.

well im glad this conversation opened up. now i get to budget into the price of 6 tires

That's not entirely accurate. If the original ST tires were quality tires and would carry their rated capacity then a lot of time you would be just fine, especially if you're running 6,000 lb. axles. A 6,000 lb. axle with 2 3500-rated ST tires would be a decent combination, IF and that's a big IF, the tires were reliable, which they aren't.

In my case my triple axle toyhauler came with 6 E-rated ST tires, and a GVWR of 18,000 lbs. If the tires were good and would actually carry what they're rated for I would have been just fine.

But there are some out there that are borderline at best with their OEM tires/wheels.

Many wheels that come on 5th wheels with ST tires are rated to 80 psi., since that is the max pressure rating for E-rated ST tires. Some people want to change to a G-rated LT tire, for higher carrying capacity, which requires a higher pressure: 110 psi. for its maximum carrying capacity.

The newer Heartland products come with 110psi rims...

Lost my first Towmax on the Cyclone (also around 17,500-18,500 loaded) in the first 600 miles. The rest went about 3500 miles or so before replacing them under warranty with Duravis R250's. LOVE them. I went up a size technically, and they are close in the centers, but they ride sooooooo much better, and they'll last soooooo much longer. I also invested in a TPMS for good measure on the coach and tv.

Take my advice, you never know when those Powerkigs will let go. Go buy the Duravis R250's (built just like the XPS ribs) and never look back. Check Sam's and Costco. I got them mounted for something like $220 a tire at Costco if I recall right. Only catch was you have to take the wheels in to them. They don't work on trailers.

I'm guessing you would have said the same thing the day I drove it home from the dealer....3 yrs and 10,000 miles ago. 🙂

Yes I would have. 🙂

FJ,
Can you get LT's in a 16in wheel or does it have to go to 17in?

Thanks

Of course you can get LT's in a 16" wheel. That is what the majority of trucks came with for years.

I wondered because I read so many of these tire threads with folks saying to change to a 17in wheel

The main reason to go with a 17.5" wheel is that a tire in that size that has mucho carrying capacity is a shorter tire than the G-rated 16" tire. The G-rated 16" tires tend to be around 31.5" and I believe the 17.5" tires that will carry even more than the G-rated are around 30-30.5". Someone can correct me if I'm wrong, but that is the impression I've gotten.

Thanks for explaining that to me FJ. Not quite sure why one would need to increase their load carrying capacity over the stock tires, but to each their own. Thanks again.

One needs to increase their capacity because the OEM tires are inadequate if RV is loaded to its full GVWR capacity

My Kung Pow tires lasted 5 months 😞

I had that same strategy only I was trying to get 2 full seasons out of my OEM tires. All was well until I hit a rugged stretch of I-81 in PA.
In a instant I was on the side of the road with a blow out.

Plans change.....stuff happens........ Good Luck you are already ahead of the game!

Two years ago on my then 5 yr old Carlisles I left home with tires that looked fine. Went on about a short 120 mile trip (in July). Got to my destination and camped for 4 days. Before I left for home...did a check and all again was fine on the tires psi..sidewalls etc. It was real hot that day and about 1/2 way home kablam..blew out a tire...and in the process tore off my center electric brake wires. The tread just separated right off the sidewalls. Called my road service and while he is replacing my tire with the spare i looked at the others and 3 of the remaining 5 tires had cracks forming on the sidewalls. It happens that fast. I dont think i would wait for "drastic" to happen.
