Contain tire Blowout?

Every few months someone posts a question on one of the numerous RV Forums I monitor, asking if it is possible to prevent the damage done to the RV when a tire fails and has a belt separation or comes apart from a sidewall Run Low Flex failure.

 I have previously written on the idea of trying to "contain" tire failure on my blog but for those that missed the information here is a summary and links for more details.

In the tire industry, we have test drums surrounded by steel grating which weighs 6 to 10# per square foot so don't forget you would need a substantial structure to support a 200# - 500# "shield over each tire position. This extra weight would also significantly decrease the amount of "stuff" you can pack into your RV.
 IMO having worked around tire test labs, an effective "shield" on an RV is unlikely to work. I feel that prevention is a much better approach.

To better understand the problem I suggest you review the following.

1. Read this post.

2. This post shows the kind of forces we are talking about.

3. Check out the safety cage around this tire test machine.

4. Buy, program and test a TPMS

5. Every 2,000 miles or annually (whichever comes first) do a "Free Spin" inspection of trailer tires.


Prevention is much better than and less expensive than trying to protect your wheel wells.

Tire industry magazine announces expansion of SAILUN brand

Modern Tire Dealer, a trade publication posted this information on Sailun brand tires.

Sailun Group Co. Ltd. has started major expansions at its production facilities located in Dongying and Shenyang, China.
“The project expansion will focus on plans to equip these additional production lines with the latest cutting-edge manufacturing and testing equipment, as well as increasing IT capabilities to meet domestic and global customer needs,” according to Sailun officials, who add that intelligent manufacturing and the application of big data will be the focus of the both expansions.
“Each facility will be equipped with the world's most advanced production equipment and fully automated tire logistics lines, aimed at effectively enhancing the level of automation, information, and intelligence of core equipment and enhanced AI in the tire manufacturing process.”
The Sailun Dongying plant expansion is a major strategic project for the Sailun Group.
After completion of the final stage, the factory expansion will allow Sailun to reach an annual production capacity of 27 million passenger tires.
The Sailun Shenyang plant expansion will focus on increasing radial commercial truck tire capacity and is also a strategic initiative for Sailun in 2020. Once complete, the plant will have an annual production capacity of more than five million truck tires.
