If they are "trailer" tires and are over 3 yrs. old replace them now, not along the road when they fail due to old age
If I could buy "light truck 8 or 10 ply tires " I would buy them instead of those dang "trailer" tires
I can't count or remember how many trailer tires I've had fail on the road
Did I mention I HATE "trailer" tires
My #2 son works in the tire shop in one of the local coal mines. His take on this? There are no trailer tires worth a [censored] available anywhere from anyone. Period.
Since when ? ...
I started having radial trailer tires blow out and have the top layer tread come off 30+ yrs. ago
The guy I bought my first enclosed car trailer (24 Ft. inside Braceo 10,000 LB GVRW) from had towed that trailer all over the U.S. chasing NHRA points and trying to set the SS/AA and SS/A records, he had gave up on getting good tires for it and had the cheapest 15 inch tires he could get when one of the trailer tires on it fail
He bought a 28 Ft. with 6200 Lb. axles with 16 inch rims and tires so they could haul a golf cart, no more tire problems on the trailer on the road
