Tires inflated to the proper psi can play a huge difference in your ride experience. Standard floor pumps are generally geared more towards road bikes or for use as all-arounders, with gauges that read from 0-160 psi. This makes it difficult to accurately pinpoint the lower pressure levels required for mountain, cyclocross, gravel, and even fat tire bikes. Silca addresses the problem with a dedicated floor pump for low pressure tires.
