How Accurate is Accutire MS-4021B?

Tire pressure is crucial for safe driving. Underinflated tires can get even the most professional driver into a lot of trouble. Poorly inflated tires heat up and might blow out. Moreover, it is difficult to steer a car with underinflated tires.

On the other hand, overinflated tires can make the ride rough. Additionally, the extra pressure could wear out the suspension parts and the engine as well. Fuel economy wise, it is more expensive.

The above facts are the reasons why you need to assure your tire has the right amount of pressure. But the big question is this; how to find out if the tire gauge is accurate?

Is your Tire Gauge Accurate?

If there is a significant difference between your device and the other two gauges, then chances are your gauge might be inaccurate. But it also could be the other two gauges are inaccurate.

If the difference is only a two to one PSI, your device is good to use.

  1. Check Using a Master Gauge
