Semi tires (or semi-pneumatic tires) are quite different from the regular kind of tires. Just like the typical kind, the semi tire has a hollow center. It doesn't have pressure within this space, though. The kind of tire is specialized for rugged use so they're designed not to come off easily. However, having them changed can be quite a chore.
This task can be overwhelming for a regular driver, but it's still pretty doable if you have the right tools. Sometimes, knowing how to make these repairs and fixes yourself can help with familiarizing yourself with the build of your vehicle. This way, you are able to troubleshoot and deal with problems as they happen.
The most important step of the whole process is preparing before the need arises. While doing your errands, make your way to a local car dealership or auto repair shop to obtain the necessary supplies for changing your semi tire. You will need to get a hydraulic jack, jack stands and, of course, a new set of tires. A bead cutter would also make the process of changing the tires a lot faster.
Replacing a semi pneumatic tire usually requires you to use a tire derimmer, on which you need to clamp the tire's rims. The derimmer would then rotate the tire automatically, and remove the tire from the rim while it rotates. The derimmer is also useful in putting in a new tire onto the rim.
There are also products that even allow you to fix the tires without having to lift the rest of the vehicle. For instance, a gadget called the E-Z way truck tire changer does exactly that. The manufacturer claims that you can cut the beads that attach the tire to the rig in less than eight seconds. Other bead cutters also do the job but you have to raise the truck for you to be able access the parts that need to be cut.
Change the tires with retreads from your auto supply store. It would be a better idea to replace all of the tires at once, especially if the new tire you will be replacing has different treads, or if the rest of the tires have worn out treads already. A vehicle runs best when the tire treads are even, and driving with uneven treads might hasten the wear and tear on the surface of the newer tire. This makes the likelihood of another blowout and thus, another potential accident higher. To stop this from happening, once one tire blows out, use the opportunity to replace the rest of the tires. It may seem very inconvenient, but in the long run, it is a step that will save you money and car expenses.
You can then call a professional to balance your wheels and make sure that the weight is evenly distributed across all the tires. Having uneven balance can cause damage not only to the tires but also to the axle. Uneven balance might also affect the stability of your ride, which is a big safety concern.
