I got kumho 857 after one of the factory tire deformed. I just didn't like the thought of maxing the tire out at 65 all the time. Every time I would stop the cheap tires were so hot it would burn my hand. I wonder if maxing the st tires out at 65 could be the problem.

The lower the air pressure in the tire the hotter they will get. Max air pressure will keep them a lot cooler, that's why tires that are low on air blow out more often than those that are up to the air pressure required and also is the reason the auto manufacturers were forced to put tire monitoring in their cars due to the fact people never seem to be able to do proper maintenance on their own.

If your tires are too hot to hold your hand on them for about 5 seconds then YOU HAVE A PROBLEM

- Your pressure is too low for the load
and/or
- You are driving too fast or too close to a tire max speed rating
and/or
- Your tires are undersized for the actual load you carry


Re "deformed" tire. Have you captured a photo? Did you record the full DOT serial and have you filed a complaint with NHTSA?

Not sure the problem was with the factory tires. I put the Kumho 857 problem went away. Seems like it handles better with less bounce rides better. I did't take a picture or check the dot the trailer was almost new. I just thought the tires was cheapest they could put on the trailer . I read about all the blow outs and being a single axle. Blow out didn't sound good.

I think the tire that are rated for the higher speed are a lot better. At least they are not maxed out on speed and load. It must me all about the money on new trailers. It a real problem on new trailers.

I max out my 16" E Westlakes at 80psi and when I temp them after stopping they're only at 105 degrees. I would guess that the lower pressure is going to create increased tire flex and greater heat.

How about on those days when you're in Arizona and it's 110 degrees outside?

Sure the temp will be higher seeing it was 70-80 degrees when I did the check. But it still will be cool enough to leave my hand on it at Arizona temps.
