Hi, OK this tire thing just keeps going around in circles.
tires aren't any good, especially if made in China.
tires will fail no matter who made them and where they are made.
tires are better made, but not really recommended for travel trailers.
tires are lower load rating size for size.
There are no proper replacements for 15" ST
There are some great trailer tires, but for 14" wheels only.
tires require more air pressure and may cause too rough a ride for Airstreams.
rated tires rated for 80 lbs pressure will fit onto your 65 lb pressure rated wheels.
tires mounted on 16" wheels will fit, but with less room left in your wheel wells.
Virtually impossible to mount tire chains with 15" wheels and more than likely impossible with 16" wheels. [Oregon law]
tires mounted on 16" wheels is a balancing act between too much pressure [rough ride] and too little pressure [possible heat concerns]
Cost of change over of about $3,000.00 to prevent $2,000.00 damage to trailer that should be covered by your insurance company. [$$$$$ rough estimates]
All tires, can and will fail, but when, where, and why.
From what I have read:
I bought a brand new trailer and I'm afraid to tow it without up grading my tires and wheels.
I have replaced over 30 tires, I think I will just park my trailer in my yard and leave it.
I only tow about 200 miles max, will I be safe?
I had several GYM fail so I switched to Maxxis. The Maxxis are much better. Well my Maxxis did last longer than my GYM, but they failed too. I went for the 16" conversion. So far so good.
I ran on 12 year old GYM's and never had a problem.
I went 50 miles on a brand new replacement GYM and it exploded.
I had all four GYM fail, [two in 3 years & two in 7 years] but no flat or blow outs all were replaced without any damage to trailer. Caught in time. [me]
And on and on and on............
