New Tires for my Jayflight 22FB

Will be replacing the tires on my TT this Summer or sooner. They are original (2013) 205/75R 15 Tow Max STR Power Kings. Build dates are 2012. Max PSI is 50#. And I believe they are Load Range C.

Would like to replace with a "better than OEM" tire.

Couple Questions:

1) It appears that Load Range D tires have a max PSI of 65#. I a waiting on word from Jayco CS, but presuming my rims will handle 65#?

2) Others here who have a comparable TT: suggested brands/models of tires I ought to consider based on your experience.

My local tire guy is suggesting Carlisle or Hankook.

I realize this may create differences of opinion. That's OK, I'm just hoping to find a consensus in the answers.

I'm in the same boat. Need new tires, but I have 13" rims, so my options are very minimal. I have been looking at Goodyear Marathon, Maxis Carlisle Sport Trail and Loadstar. The first two are radial, and the second two are bias.

Marathon and Maxis have a good reputation here on Jaycoowners.com

I have Carlisle on my utility trailer and have had good luck with them, not sure, but I expect they are bias. I just replaced them last year, the old tires were 14 years old, no cracking, looked almost new, and had a lot of miles on them. But I just did not trust them anymore.

Radial or bias ply tires?
Radial tires have plies that run perpendicularly across the tire and belts (often made of steel) running below the tread around the tire’s circumference. Bias ply tires have their plies running at 30 angles (like the stripes on a candy cane). Most motorists believe radials are better (and they are for your auto). Should you buy them for your trailer?
The answer depends on your trailer’s handling. Bias ply tires have stiffer sidewalls, so if your rig tends to sway, they may help reduce this problem. They also have advantages for carrying heavy loads. Radials, as most of us know, are vastly superior for tread wear. They’ll last an average of 40,000 miles vs. 12,000 for bias plies. However, oxidation, not tread wear, wears out trailer tires. Radial tires are also less prone to developing flat spots on one side when they are parked in the same position for weeks at a time, and tend to run cooler on long trips. Bottom line: consider your trailer’s handling and the manufacturer’s recommended tire type. If you travel long distances and/or put lots of miles on your tires every year, radials are worth the extra cost.

Each of your trailer’s tires should be the same type, size, and construction—do not mix bias-belted and radial tires. In selecting tires for your trailer, buy the size, type, and load range found on the trailer’s certification label or in the owner’s manual. Keep in mind that tires have a load rating that indicates the amount of weight they can carry safely. That includes toys, Igloo coolers and camping gear. Overloading can lead to a large heat buildup, causing accelerated wear or a blowout.

Thanks for the good info.
Believe we will be going with radials; we just finished our first Winter trip of over 5K miles and hope to be doing it each year ahead. That would amount to 25K miles in five years plus some Summer getaways.
So, although they are going to be shot/unsafe in five or less anyway, at least I'd have the tread toward the end. Trailer sways not (well, a bit so if a massive semi zooms by me), and the current tires are radial and nothing scary or severe happened on this journey.

frjeff: Are your tires worn or do they have dry rot, cuts etc.? If they have good tread why replace the oem? The recommendation by tire mfg's are 6 years (their wallet).
The TT below 30 ft. doesn't seem to have any problems with oem. Then there is only a handful what have problems with 30 ft. and over. All tires are just about China made.
Your rims are good for 80 psi. Just go to Dexstar Rim and if you have the 8 spoke white steel rim then you can verify. I run my Tires 10 years and even my dealer said so. But the tire shop likes the 5 to 6 year range because he's talking about his wallet.
No matter Carlisle or Hankook they are still China made. It is all a matter of taking care of tires; don't run under inflated and cover them for UV-rays.

Your rims are likely only good to 60psi. If you have 3500lb axles with 5-bolt hubs then you're likely 60psi max on the rim. This is true for the aluminum rims (which I have) but I can't say for certain if the steel wheels are the same.

The 5000lb+ axles with 6 bolt hubs are the ones good up to 80psi. I looked into this recently because I am planning on going to LR D tires when I replace mine, and the tires are rated to 65 but my rims are good to 60. I still think a load range higher at 5psi under max is better than my current load range maxed out at max pressure 50psi.

The Dexstar 15x5 rims that came on my 2015 trailer have a model number 17-143. The sticker says they are rated for 1820 lbs. Like you I want to go from a C to a D rated tire. And I was concerned about tire inflation pressures. I contacted Dexstar because their website now rates that model wheel for 2150 lbs. and 80 psi. They confirmed that I could safely mount D rated tires on my existing rims.

Thanks for that, Popcycle. I have the same rims, and saw that on the Dexstar specs page they don't carry the 1820 X 15" 8 spoke rims now. Last year I just assumed my rims would handle 15 pounds more pressure, so I upgraded without checking. Good to know for sure I'm legal.

Mine are also 17-143. So, I am hoping my 13 is rated like yours. Have contacted Dexter, so we shall see. Thanks for the help!!

Good News from Dexstar

Happy to receive this response from Dexstar this morning:

Good Morning, Jeff~ The 017-143 wheels are tested and approved for 2150lbs at 80psi, so you may use the D range tires without issues.

Please let us know if you need anything further!

Thank you for your inquiry!!
