I will share my personal story as it's the only reference I can give. I drive a 2019 f250 and tires reccomend 75 to 80 psi per tire. Tried airing up my tire and first machine the machine was busted and would not go above 35 psi. Second machine only increased 1 psi very slowly, what seemed like forever. I gave up on machines and drove home on low tire pressure. I used these machines at the beccees on north 75 in kentucky at the richmond exit. I do not reccomend anyone trying to use machines.
