This is what I would do too.

I would bite the bullet and replace all 4 with the GY Endurance in LRD's and get on down the road.


And I would upgrade to 15" tires and wheels.

Steel wheels are pretty cheap from www.etrailer.com

Sell your current tires and wheels on Craigslist

I'd upgrade to 15s or 16s as well.
Mind boggling that a 30' TT has 14" wheels / tires on it.

Not sure I'd buy a 30' TT that only had 14" wheels. That manufacturer is cutting corners, and if it is cutting corners with equipment that easily viewable, where else is the manufacturer cutting corners.

A friend in his 70s has been camping for years, he replaces two tires every two years, always keeps the best for spare of old tires. Also has bearings repacked while wheels are off.. Never had tire problem on trailer and he doesn't have to pay for 4 tires all at once..

Unless one has hard engineering data supporting installing wheels/tires that exceed the designed and rated axle weights IMO doesn't make sense. For many light and ultra light wt trailers with 3500lb axles putting tires that are rated over 3500lbs is not really needed. I understand why one would try and point to the age old "reserve capacity" concept, but I'm not sure how valid that is today.

I have never seen any valid and documented studies on this area and I personally can only see it being possibly beneficial if one encounters a road hazard like "curbing" or hitting a pothole where a much higher capacity tire might not be as damaged as a lighter tire.

I have for over 25,000 miles on this trailer run my tires to within 25 to 50lbs of their max load carrying capacity and have seen ZERO adverse effects. That is only a data set of one, but is one I know is good and all that is using the dreaded "china bomb" GY Marathon trailer tires. The only issue I have seen is the one set of Kumho 857s tires that had that extra capacity of over 300lbs per tire load carrying capacity where I lost three of them within 500 miles of each other from tread separation and sidewall bulging and they were less than 4 years old and only had around 5,000 miles use on them and had been running with over 300lbs excess load capacity per tire.

I did this exact thing on our vacation last year. 1000 miles into our trip I had 2 GY Marathons LR D go bad on me. Belts separated but no blowouts. Had 2 new GY Endurance LR E installed and put another 2000 miles on during that trip. Finished the summer of 2017 and traveled all of 2018 with that arrangement and no problems. I think the other Marathons will age out this year and plan to replace them with the endurance next spring.
