The best we can really do...
For peace of mind, what you should really do is to take your trailer to a good and respected tire store and have them check out your tires.
They should be able tell you if there is a problem with them.
And probably the very best thing you can do is to get those trailer tires balanced!
I need to do that myself . . .
Since tire pressure is one of the most critical safety factors when trailering, I think my concerns are legitimate. They may have voided the tire warranty. I plan to call the manufacturer regarding that, as well. I'm not optimistic about my dealer doing anything , but I'll ask.
Now I'm not saying that we shouldn't keep an eye on our trailer tires, but I am starting to think that many here are over analyzing what they need to do and could perhaps be bringing on more issues by being over protective of their tires with their efforts.
The best that we can really do is to make sure that our tires are filled to pressure before we leave on a journey and keep an eye on them each time we stop, checking for uneven wear, bubbles, and perhaps looking for nails or other puncture wounds.
But tweaking and adjusting tire pressures at each stop along the way could be doing more harm than good as we can't really get an accurate read on them when they are hot.
And adding cold air to a hot tire can't be good!
Which brings me to another thought . . .
Is nitrogen really good for our tires or can it actually be bad for the rubber?
And, for those who use nitrogen in your trailer tires, what good is having it in the tires unless you carry a tank of it for when you do need to tweak the pressure?
I'm sure someone will chime in with "You can alway add air to nitrogen!" . . .
Well, if this is the case, then why even bother with it!
I honestly think that nitrogen is just a way for the tire stores to collect an extra $20 bucks from us whenever we visit . . .
Heck . . . the other day I scuffed my passenger side trailer tires on a curb . . .
If I were to believe many of the tire posts here in the chats, I should run right over to the tire store and replace them all as I have just damaged my tires beyond use!
Upon inspection, I just barely rubbed them on the curb . . . but that is not the point!
