Have not had anything good to say about Goodyear in alot of years but I figured it was built for price oem tires on the Fords and GM stuff I've had. However the Goodyear Marathon's that came on the Phoenix trailer have done the job with no troubles.

I hope Goodyear and Carlisle have gotten better they used to be garbage. I have had much better luck with the cheap Chinese tires. Never had a problem with one. I just sold a boat to a guy in Texas yesterday. The trailer had 6 year old no names on it. I drove 400 miles in 100 degree heat and handed over to the new owner who drove another 800 miles. So 1200 miles non-stop through the Southwest. No tire failures. I would still have a hard time buying Carlisle or Goodyear even if they are made in the USA just because they caused me so many problems in the past.

I have had problems with the cheap valve stems that tire shops install so I always go to an auto parts store and buy the metal valve stems and give them to the installers. Haven't had a problem since I started doing that.

The heavier load range is added insurance however tires and trailer tires have speed,ratings as well. Ask the dealer what they are. You don't want a load range E tire with a speed rating of 55mph then rip down the interstate at 75!   Just need to find the balance between the 2.

Not sure I agree using LT’s, is there any information to go with that thought. I must be the only person who has repeatedly been burned by Goodyear whether LT or ST. Every swinging monkey on this website says use Goodyear. I must’ve been installing mine backwards.

Its a common topic in RV forums lots of opinions . I'm not sure if I buy all the feedback but the 65mph max speed on ST tires is a concern .

High end Carlisle are still USA made. I hadn’t lost my confidence in them yet.

For what it's worth the manual for your boat recommends load range D for single axle trailers and C for tandem.

I just got a set of the new Goodyear, made is the good ole USA, Endurance E rated (80 psi) for my ride down to the Rukus. My old D rated tires looked and towed great but were too old. My other boat is perfectly matched weight wise to the C rated tires and those damn things always go at 5 years old -- often on the side of the road. Last time I upgraded to Good Year's (the new ones were not yet available so I got the Marathons -- made in the corona rim) and I keep them 5 psi over the 50 limit to try and help get a good 5 years out of them. My experience is the excess load capacity way outperforms over time.

My 96 Sport is on its original Ramlin single (5200) axle trailer.

It needs new tires. Its got ST225/75R15. The current tires are rated load range C which can't be correct.
C = 2150 each = 4300 lbs
D = 2540 each = 5080 lbs
E = 2830 each = 5660 lbs

Dry boat weight is 2700 lbs and trailer is about 1200 lbs. Add full tank at 210 lbs and random stuff in boat takes weight (~4200 lbs) to the very limit of C load range with little to no buffer.

Also, since the axle is a 5200 lb axle, I assume load range D would be the correct tire spec.

Problem is this...I need to tow the boat home this weekend. Local tire shop near the boat's current location has the tire in-stock in Load Range E. They are giving it to me for same price as load range D. E is obviously overkill, especially considering C is on it now. (They do have C in stock by the way).

Is it okay to go with the E load range even though I don't need it? Or is C really okay afterall? (I live about 1.25 hours from the lake, so there will be some highway driving occasionally when the boat is taken home...its not like the boat only ever travels 1 mile to boat launch).
