'69 Globetrotter tires/wheels
The tires that were on my recently acquired '69 Globetrotter bear the following information. CARLISLE USA TRAIL, ST225/75D15, Tread 4 plies nylon cord, Sidewall 4 plies nylon cord, max load 2150 @ 50 psi cold, load range “C” tubeless. The spare tire appears to be slightly newer and has the same information except for “max load 2440 at 65 psi cold. The spare also has the following: dot UU HH ACD0104. The other tires have similar info but it is becoming illegible. All tires are mounted on wheels shown below. My questions are:
Are these the specified tires for a '69 Globetrotter?
Are these the best tires for a '69 Globetrotter given what is available in 2010.
Is UU HH ACD0104 the age code that says the tire was made in the first week of 2004?
Is Marathon, which seems to get so much bad press on this site the tire brand that comes with new Airstreams?
Is the wheel shown original for airstream?
These wheels do not appear to have any means for attaching hubcaps. Does that mean I can't get those half moon hubcaps?
Most important is what are the names of some of the best brands of tire currently on the market?
I say “Most important ...” after reading about all the blowouts and subsequent body damage on this site. Since my trailer has only on axle, I want to do everything I can to avoid tire failure.
