Checking your tire pressure regularly is very important because air pressure in tires changes over time. How does tire pressure loss occur you might be wondering? Over a period of time air molecules will penetrate right through the sidewalls. This process is called diffusion. Tires can be brand new and they will still leak and the reason is because on a microscopic level tires are made up of fishnet-like masses of long, stringy molecules. No matter what the molecules that make up Air are tinier then the molecules that make up tires. Semi Truck Tires can lose up to 2psi per month. If you don’t check your tires for 4 months your tires could be as low as 10psi.
Loosing Air due to a dirty bead
If the wheel and bead surfaces are not clean or if the wheel is suffering from corrosion or even worse the mounting lubricant doesn’t coat the bead or wheel properly then it is also likely that you will experience even more air loss due to these issues. It’s important that the company that replaces your tires takes the proper precautions to ensuring this situation does not occur.
Having low tire pressure is bad for a number of reasons because underinflated tires will wear out faster. The main reason is uneven tire wear or otherwise known as irregular wear. Uneven tire wear will shorten the lifespan of the tire and sometimes make it difficult or impossible to retread. Tires that have low tire pressure will also have more rolling resistance making it more likely to get damaged because more surface area of the tire is now making contact with the road and the debris that exists on the road. The more rolling resistance your truck has the more fuel it takes to move your load. Cost of fuel is a major factor within the trucking business. Overspending on fuel means less profits. Shortened lifespan of tires also means less overall profit and increased chances of your tire having a blowout or your semi ending up stuck on the side of the road causing you unnecessary downtime and unplanned expenses for service calls.
Overinflated Tires is not good either. Overinflated tires will be more stiff and have less give and likely become more susceptible to impact damage like when you hit a pothole on the road.
