We had our first flat on a goodyear marathon, tires are 4 years old. And I tow at 65-70.
Was sold a Triagle brand tire. Looks the same, but have not found any info.
I would buy the Good year again.

I posted elsewhere about my Chinese tire blow out. I also posted about the travel trailer passing me doing 75 mph with 15" tires. Don't know what brand they are but still driving too fast.
I was also passed in Savannah by a truck pulling a closed utility trailer of about 10' in length. He was weaving in and out of traffic, doing about 75 mph with 1 tire slinging rubber all over the place and the other tire behind it almost sagging on the rim. I believe he had 14" tires.
The Canadian Marathons I have seem to be doing fine, don't run over 112 deg. F on 90 degree days. I'm torn between replacing them or leaving them
The general consensus is Maxxis is the best 15" with Denman following behind. Problem I have is that the Maxxis is not readily available but Denman seems to be available.

I tend not to follow the herds. However i have never driven over 65 and have had chronic problems with ply separation on the marathons, but never until after 2 years old.
I am trying out a set of Titan 15 inch load range E tires on one of my axles, only have one trip to the east coast from IL on them thus far, so would not put my paycheck on them at this time.
So it is just a direction I took. And to beat a couple of police out, you should be aware of the wheel pressure rating and how you want to handle that.

I think there are two reasons some people have tire problems.
One is that most of the ST tires are speed rated at 62 MPH and the other is that some people will not weigh their set ups and wind up overloading the tires.
Most people want to keep up with traffic when towing and will drive between 65 and 70 or even faster to do so for hours at a time. Most ST tires are only speed rated for 62 MPH max. and could blow from excessive heat when driving at 65-75.
Others will load their trailers with all the "stuff" they want to take and because they don't weigh their set ups, wind up overloading the tires, this could also happen if you are using LT tires.
I also think you should switch from the ST tire to the LT tire IF you can find one in your size.
The LT tire is rated at 75 MPH and gives a greater safety margin when driving at higher speeds.
Most of the heavier trailers will come from the manufacturer with LT tires that are speed rated at 75 MPH.
I still keep the speed at 62 or below but the extra safety margin of the LT tire is nice to have.
Both my last two Newmars came from the factory with LT Goodyear tires and we have had no tire issues at all.
If you go to this site and follow the directions you can find out where your tires were made.
The last four numbers in the DOT code is the week and year the tires were made, (2207 would be the 22nd week of 2007) If you have a three digit code the tires were made before 2000.

Thanks Dave
Kodiak, I can't switch because the existing 15" are 1" from my shocks. They cannot be moved and I believe they really help.
When I Google Goodyear in Wilmington, DE, I end up with different tire chains and no "official" store. My tire threw the tread cap and the side walls blew out. Dealer says Goodyear only warrants tread life. I told him politely that he was wrong. Had him remove the carcass and I kept the destroyed rim. I have decided that shipping the tire to Goodyear was not worth the cost.
I had a Denman installed on the painted rim and my Canadian Marathon put on the new aluminum rim. I'm taking the Denman back to Tire Kingdom today (I bought it in Tallahassee). I am concerned because it has 7 ounces of weights on it. The dealer did admit that that was a lot of weight but they sometimes see that on trailer tires. I did not ask him to lug center balance. I will question him on that.

Charlie, Another thing you might try when re-balancing the tire is to have the dealer turn the tire in relation to the rim 180 degrees. I have found that doing this will sometimes result in using less wheel weights.
Also make sure the tire is actually round, not egg shaped.

Thanks-Went back to NTB but the salesman that worked with me will be back tomorrow. I plan on having the tire rotated 180 degrees and to make sure that they were lug centered balanced. Guy I spoke to today said that was standard procedure but I want to make sure.

I went for GY Marathon ST205/75/15 (Load Range C) tires to GY WrangerHT LT215/75/15 (Load Range D) tires. Real happy and I drive 75+ in the Mojave desert.
Both are approved for TT use.

Good move but they don't have the load carrying capacity that I need.
Took my Denman spare back to Tire Kingdom yesterday and told them I did not like the 7+ ounces of weight. They assured me that they lug centered balanced the tire. I had them check again. It was not lug centered balanced. Tire was rebalanced again and weight is now 2 ounce. Same as when the Marathon was on it.
There are several posters on here that say to have them lug centered balanced and I have in the past but did not request it this time.

trailer wheels are lug centered BUT the lugs are not concentric with the wheels mounting flange. Thats why tire shops that have been around the trailer industry awhile simple don't recommend balancing a trailer tire unless the customer insists. Balance a steel trailer wheel/tire assembly and then rotate 45/90 or 180 degrees and mount it back on the trailer hub and it will more than likely still be unbalanced. Well made aluminum trailer wheel tire mounting flange may be concentric to the lugs. Automotive wheels are center hole located to a machined flange on a axle and can be balanced for any position on the hub.
