Some pneumatic semi-trailers can be used continuously for seven or eight years without any problems, and some vehicles can be used for one or two years. The service life of an inflatable semi-trailer depends on the quality of the Semi Trailer Manufacturers and how the owner uses it.
At present, numerous semi-trailers are inflatable, which is cheaper than refueling, therefore many drivers choose to buy inflatable semi-trailers. Some semitrailers are gas-gas combined, with or without gas.
If used correctly and maintained correctly, the car can last for years without problems. If used incorrectly and poorly maintained, the car may develop problems after a period of use.
​Elderly drivers commonly say "three separate seven separate", which is not without reason. ​Numerous cars can drive more than 1 million kilometers, continuous use for more than ten years, without any problems. The car is not of excellent quality, but appropriately used and maintained.
If you want your car to serve you for a few extra years, you should drive it the right way and keep it in the right way.
If inflatable semi-trailers are the future in the long run, inflatable semi-trailers may be phased out.
