New Tires

Internet forums are great for pointing you in a direction, but trust the verified sources (manufacturers, etc.) for the final say.

Which is why you follow the manufacturer's load charts and don't just fill them up to Max PSI!

I upgraded tires to a larger size on my last trailer. If I loaded them up to Max PSI, they would be extremely overinflated. You go by the PSI recommended on the tire label on the trailer if you have the sized OEM tire. If you don't, you use the load charts.

Lots of similar opines here. Some don't address the root of the issue.

Let me summarize:

1. Buy the tires that meet the boat/motor/trailer requirements. If you need a load range C, don't buy a load range XXX because you think they are better.
2. Inflate to near max sidewall specified pressure. Trailer tires don't suffer from over-inflation, but under-inflation will kill them on the interstate. (see step 1 - if you missed that part then you're on your own. If you need to consult charts and calculate your psi you bought the wrong tires)
3. Buy the best USA made tires that you can. If you insist on chinabombs because they meet your budget, do the R&D to be sure that the brand is reliable.
4. Whatever you buy, dump them after no more than 4 years.

You can go up a load range with zero drawback, as long as you follow the load chart, or just max it out. Depending on who you talk to.The stiffer tire will run colder.

Exactly. When I was in a place where I could only get load range E and I really only needed D, I just inflated to get the same load rating of the D which was 65 PSI. There was zero need to run it at 80PSI. That's why they have the charts. Of course you will always be people that think they know more than the tire manufacturer and just inflate to max.

That's good advice. But why not just buy the right tires in the first place?

If you had a tire failure on the highway and you didn't have an option, then maybe there was a pre-existing problem that needed addressing.

Let me say this again "When I was in a place where I could only get load range E and I really only needed D..."

I was on a trip...second of my 3 year old china tires had just blown. This was with a trailer that I had sitting on blocks to keep the weight off the tires too.

Right now in the current state of tires.. Goodyear Endurance are out of production for the moment, stock is zero and suppliers are told they will start running them next quarter... We needed to re stock 235/85R16's today, and we had to get LRF's instead of E's because that is what we could get.. Normally we don't stock F's as we upgrade to 14 ply for those usually as it's some type of equipment trailer..

The tires I install, don't blow out. They wear out. In general
