Nope, "supposedly" the tires are designed to take the increase in temperature as they heat up. Cold inflation numbers are what you should use.

A few things come to mind with the China Bombs... First; the manufacturers are cutting it way to close, they don't give you any leeway on the capacity. Two; tires lose capacity as they age. You have brand new tires loaded to 95% of capacity they will be loaded to over capacity a couple of years down the road and you didn't change anything.

YES inflate to 65psi for LR-D (80 for LR-E) when the tires are at ambient temperature (not driven on or in direct sunlight for previous two hours)


Tires, even those made in China do not "expload" due to the increase in pressure of 10 to 15 psi. If you have a sidewall failure it is probably becaues the sidewalwas being over flexed due to excess load and low inflation. Yes you may think it exploded because you were surprised but you need to learn more about tire failures. You can learn more about the two primary reasons for tires to fail (Belt Separation and Run Low Sidewall felx failure) by reading my blog. You can start with this post.

Others on "China Bomb or Pot Hole" or "How good are Chinese tires".
The index (on the left side of blog) currently identified 40 mentions of "Blowout", 5 on "Hot Tire Pressure" and 8 on "Sidewall failure".

you need to learn more about why these tires keep failing. maybe you should do some investigation yourself. I check my tires and am very aware of the issues and anything else that affect them. people are complaining about the inferior tires placed on these vehicles. I have looked at several rv manufacturers, the good ones put decent tires on their vehicle. Why? I know some "american" brands are actually made in china as their country of origin. These tires are placed on the vehicle and approved by the manufacturer. I can see I'm not getting anywhere with this stuff. I checked the weight, my RV weighs in at over 8k for the rear axles. That is more weight than their load range D tires should be able to take. IT COMES THAT WAY FROM THE FACTORY. They know the vehicle weighs that much dry. I took photos of the damaged tires, I wish you would have been on the forum then so I could have sent them to you.

If your GAWY exceeds the load capacity of the tires provided by the RV MFG that would be a violation of Federal DOT Regulations. IN the past this resulted is a free replacement of the tires. File a complaint with NHTSA. Have a picture of the certification lableond of the tire load capacity on the tires.

Yes I own an RV
Current 2016 Class-C w/ OE LT LR-E tires
Previous 2008 Class-C w/OE LT tires LR-E tires
previous (1984 - 1997) a couple of 1 ton dually C3500 w/ slide in camper pulling 26' enclosed race car hauler w/Camaro, tools etc inside. I owned and drove semi-pro Road Courses. Lime Rock to Riverside. Daytona to Watkins Glen and half dozen other road courses. Set lap records at 6 tracks and did tire evaluation on and off the track.



Race car trailer came with bias ST tires that I changed to LR-E LT radials.


Any other questions?



Any more questions.

Yeah, Chinese tires blow up because of poor quality; they're complete junk. Kinda like the poor quality trailers they're installed on. Many times we have trailers show up at the dealer where I work with the spare tire installed because the Chinese tire couldn't endure the trip from Indiana to Tucson.
