Trailer tire question

[pianewman]

DonV is exactly right. Careful with distance if you've got cracking sidewalls.

I got 28k serious highway miles (65mph) on Goodyear Marathons (ST175/80R13 radials, made in New Zealand), on a single axle 2600lb. popup. I stored the trailer on concrete, on the tires, for 4 winters. Both tires threw their treads, in 103f heat, on the highway, within 400 miles of each other. (They showed NO signs of stress, wear was very even, NO cracks on the sidewalls). I've replaced them with another pair, now made in China.

I've read both good and bad about the Chinese produced Goodyears, all of the "bad" tires were a different size than mine. Supposedly, Goodyear has improved quality control, but who knows? I've only got <1k miles on the new(er) tires.

Hope this helps.
