Well I took my first trip with the new camper(in sig) and had my first blowout. Running the infamous Goodyear Marathon 225/75/15D. Anyone else running this size TT running the Goodyears or have you upgraded to something else or went to a larger tire? From reading here the Maxxis sounds like the best tire in this size but is the move up from a 2540 lb tire to a 2830(E) tire enough of a jump? Should I be looking at 16's?

ok, so you are in the same boat I was. My TT is just about the same size weight..
I wanted to go with 16" rims and BFG commercial TAs but could not swing the size change without some suspension modifications..
I went with E-rated 15" ST tires.. I run them at 80psi and limit my speed to 65mph which is what they are rated for.
If you could swing 16"s that is where I would go. Other than that I would get E rated 15"s.
Maxxis, Carlisle and Denman were three that I could find.. I ended up with Carlisle's due to the options for getting them where I live..
In the grand scheme of things, I think a lot of the tire issues reported are a mix of TT manufacturers putting on too low of a rated tire on heavy trailers ,people not keeping them properly inflated and excessive speed..

I agree with the too low of tire on heavy trailers and I should have remembered my parents blowing 3 Goodyears trying to get home from Texas one winter. They have the same tire on their Hitchhiker 5ver.
I don't think the 65 mph speed limit is much of a problem until you max out the tire rating as I am doing now with this camper.
I just don't want to be scared to go anywhere again.

I think the speed is relevant as that is what the ST tire rating calls out.. Seems like heat is the major killer of these tires. pressure and speed affect this.
The other thing about speed is how much collateral damage is caused when you have a blowout... When I had mine I was going about 60-65 and actually heard the tire blow, so I was able to get stopped before the tire disintegrated and beat up the camper..
I talked to a guy a couple of weeks ago and he mentioned towing a TT identical to mine 75-80 mph... I just couldn't imagine having a blowout at that speed..
but to each his own,

A D rated tire on that size of an RV is too small of a trailer...my old fifth wheel had 15" D rated trailer tires...imediately upgraded them to 16" E rated truck tire and never had any more problems...
I would recommend you upgrade to at least an E rated tire and if you can a 16" E rated truck tire

What troll3193 says is worth more than 2 cents. He speaks the truth!
(hope he's not a lawyer or politician)
If you can get 16" under your rig, that's the way to go.
If not, 15" load range "E" is your next best option. Be aware, though. Your rims should be rated to handle the 80 psi. Stock steel rims that came with load range "D" tires usually are only rated to 70 psi. The aluminum 15" rims should be able to handle the 80 psi. If you have steel rims and can't afford aluminum, set the pressures at 70 psi if you get load range "E" tires. It will increase your load capacity of your tires more than the "D" tires @ 60 psi.
I also suggest replacing the tire valves with steel ones. They don't rot out and will last longer.

Until you weigh your trailer, the weight on your axles is just one big guess.
I know from past experience you can load a lot more into a trailer than you would ever realize, so without weighing the trailer it's all just a big guess.
You will need to know the weight on your axles to be able to pick the right tire.

Trailer in driveway just the way it was when I tried to bring it home. I'll go weigh it and let you know the results.

Everyone raves about Jayco and their legendary quality. However no one talks about their dirty little secret. Undersized tires! A trailer of that size Must have at minimum 16 inch wheels with LT rated tires IMHO. But then again I am willing to bet that if you look at the axle ratings they are like 4000 or maybe 5200 pound axles.

How about I go weigh each axle and then both and then we will decide if it is a tire problem or a travel trailer problem. If I got 4000 lbs on one axle which has tires on it for 5080 lbs (2540 x2)how the *#@* could it be only Jayco's fault? If you can prove to me that only Jayco puts too small of tire under their TT and all the other travel trailer companies are running 16" tires then I'll consider you a wise man.
I was really looking to get rid of the Goodyear tire not the Jayco camper. I was looking for quality opinions. I have two Gooyear dealers here in my town and one won't get me another Goodyear Marathon to replace my blowout because he "didn't want to be responsible for tearing up my TT when it happens again". And the other had to order one in but said he would only sell me a Denman tire.
