n00b questions: Wheel sizes

My first post and I'm almost completely ignorant about Airstreams so show
some mercy!

1. Am I correct in assuming that 15" wheels are standard?
2. Are 16s a factory option?
3. Are 16s the max given the seemingly tight wheel wells?
4. How stout are AS axles? I know that is subjective but I gotta ask.

I ask because I intend to do a lot of boondocking.

Thanks in advance!

Welcome, Mine has 14 inch wheels. I think the only reason to go larger is the increased choice of available tires.


Do you know what a learning experience is? A learning experience is one of those things that says "You know that thing that you just did? Don't do that."

65 versus 70 mph, & E rated

Getting above the 65 mph limit and being able to run 70 in certain situations is one benefit.
Getting more safety margin with the E-rated is another.
Like the previous post said: it is about the limited number of choices in the 15.

65 vs 70 might spark all kinds of rebuttal, but even for those that really try to only run 65 might find times they actually occasionally run over slightly over 65. The problem then is they are exceeding the rated speed. Easier to have tires rated above 65 and not worry about those times when looking down and maybe pushing 68 - 70.

Hi from AZ. . . no, depends on length, yes, depends on length, probably, depends on length. . . axles are good, depends on year. . . . . . In other words, no one answer to your questions. Been making these things for years, so lots o sizes, models, features. . .good luck and welcome aboard !. . . Craig

The two reasons I want to go larger are to be able to use LT tires
and a little more clearance - every little bit helps when you're
boondocking I would assume.

I've seen where people have put 16s on their Airstreams.

Larger tires may give you more clearance (1/2"), but will go further up into the wheel well limiting how much you can 'bounce' when boondocking.
You can replace axles with ones with a higher degree of drop, but this raises the center of gravity of the trailer.
Everything is a trade.
If you have an older trailer, they will sag over time - need to be replaced every 20 years or so. This will increase you ground clearance.
I have found the 15" that came with my Airstream is a good compromise - the engineers that designed it may know what they were doing.

If wanting trailer for boondocking, and rough roads, might look at the Oliver trailer
