I have been reading about this tire issue for months but can not seem to get a grip on what to buy. Radials v. bias, D's for E's, Marathon v. Maxxis. Man, I am confused.
It took three hours to change a tire this weekend because if wouldn't fit in the wheel well, I had to deflate it first. Could someone please tell me what to do???????
Airstream did considerable research when they selected a tire brand and model, many years ago.
Granted that brand had a problem, but that was a long time ago.
The correct tire for your trailer is Goodyear Marathon, ST 225/75 R 15. You should use load range "D". However, your wheels are old. If 6 ply or "C" tires have been on them for years, then you cannot change to "D" tires as the wheels will split.
Assuming you can use the "D" tires, then a pressure of 55 psi is adequate.
Remember that an Airstream loves a soft ride. Anything you do to alter that will eventually lead to major repairs.
You should also check you axles out, to make sure that they are ok. If not ok, then the trailer will bottom out when hitting bumps.
And finally, the tire, wheel and hub and drums should be balanced as an assembly. If not, once again, your pocket book will suffer the penalties, along with the trailer.
The following article, will teach you how to check your axles out, in less than a minute.
