I think this has been discussed before but I'm bringing it up again since I had a tire blow out at 60 mph the other day. 013
My trailer tires are rated at 50 psi and I've always tried to keep the pressure at exactly 50 psi. I add air on cold days and let some out when it's hot in order to keep the cold tire pressure at 50 psi but with the recent blow out of a perfectly good tire, I'm thinking that with the 98 degree temps we've been having, the asphalt has to be in the 100's and that heat is causing the tire pressure to exceed 50 psi.
How much pressure do you keep in your trailer tires?

50 psi in mine, tires were around 115 degrees F on the way to and from Ft Lauderdale. No problems, how old are those tires ?.

I think the one that blew out was less than a year old. I dropped the pressure from 50 psi to 47 psi in all 4 tires yesterday. I'm dragging the boat to the gulf tomorrow and again this weekend and it's close to 100 degrees out there! |

A blowout at 60 mph is a scary thing indeed. Happened to me at 4 a.m. when the temps were in the 70s. I run my tires at 45# and I check them cold before every trip. Don't know if I ran over something or what. Maybe tires just blow up sometimes.

Maybe tires just blow up sometimes. That may be the case. I thought maybe the heat caused it but there might have been a weak spot or a defect in it. It sounded like a bomb when it blew. Tandem axles let me get home without stopping to change a flat so it could have been worse. |

I run my triple axle at 45 psi. Tires are 50 is max. Best thing if possible is getting your tires filled with nitrogen it will eliminate excessive tire pressures with the heating of the tire. We run 200 psi in our jet tires and we do hot tire pressures check and psi will raise only 10-15 psi

My Carlisle's say 50psi max. Been all over Florida with them in the past two years. If there between 40 and 50 all ,4, together, i usually let them ride. If one, even the spare, is getting closer to forty, that's when I add air to all. No issues so far. Suck's, but maybe you just had a bad tire day...

I was trailering back from Simpleman land and heard about the 104 temps and 109 heat index and thought about this thread. I mentioned that I felt a blowout coming before we left. Sure enough I got on some brand new blacktop on I-85N out of Montgomery, and the front port tire blew within 15 minutes. 103F on 155F blacktop was not fun at all.

There is a date stamp on the sidewall of tires to determine the "shelf life". They might have been an old tire off the shelf?? A lot of times tire retailers don't rotate their stock and the smaller trailer size tires do not sell as steadily as auto and truck sizes do. Just a thought.

I'm going to run the rest of this year on my current tires, and then I'm getting some that are load range D. I think the C's are borderline.

I’m a big fan of being over prepared. My trailer had C on it. Had them for a season and then I went to D radials

I run mine between 60 and 65 psi. I got the goodyear endurance I believe. They were the only trailer tires I could find that are still manufactured in the US, they have the D load rating, and they are rated to over 80 miles per hour approximately. (I can't remember) Most trailer tires are only rated to 65 mph. I have no intentions of going 80 with a trailer but 65-70 I do regulary.
Also from what I understand in order for the tires to retain maximum load rating they need to be at max pressure when cold. Defining cold I guess is the problem?

I posted about this before also. I f you keep buying china bomb tires you better be ready on the road. Why not buy the American made goodyear endurance made in Gadsden ala and forget about the Chinese and Asian junk. And if I remember you run way smaller tires than your trailer calls for Juan, could be reason for over heat. Just sayin  |

They're 13" and nothing larger will fit without removing or modifying the fenders so I'm stuck with 13" wheels and tires.  I get Trailer or Power King tires from a local tire shop at $60 each and until yesterday, I didn't realize they were made in China. I won't be buying them again the next time I need another tire. They're also "C" rated tires and I wasn't aware that there's a speed rating limit based on the rating. Everything I've read online ( so it can't be wrong  ) says the only difference in "C" and "D" rated tires is that "D" rated tires have a slightly higher load capacity and psi but they still won't carry any more weight because your axles determine capacity and not the tires. "C" rated tires have a load capacity of 3,640 pounds on a single axle trailer and mine is a tandem trailer and the boat is no where near that weight so I think the "C" rating is fine. I just won't buy China tires any more. The rating has nothing to do with tire wear or performance. |

When my tire popped it blew the fender clear off of the trailer. I learned soon that putting a new fender on presents some challenges, but it is not terribly expensive. I'd take some of that money you've saved by buying $60 tires and get some 15" wheels and put real tires on them.
Maybe 13" tires on a dual-axle trailer is the norm, but it just sounds wrong...

I would have changed the wheels from 13" to 14" at one time but the tires are fairly new, I bought 13" mag wheels, I'd have to replace or modify the fenders, and the trailer would sit higher than it does now......So, it's too much trouble and it came with 13" wheels and has served me well all these years (except for an occasional blow out) so far so I'll keep the 13's. (but I do wish they were 14" only because they would turn a few revolutions less and maybe last longer.)  |

Forgot about those mag wheels. That makes all the difference. I guess as long as you don't blow 2 on the same side, you're okay.
