Bests & Worsts Reviews from Amazon

I bought this to re-inflate the 35" tires on my 2018 Wrangler after airing them down to increase traction off road. This inflates the 35" x 12.5" x 17" Goodyear Duratracs from 15 PSI to 35 PSI in just over 2 minutes each. It gets a bit warm but cools down quickly. The power cables and air hose are plenty long enough to place the unit on the front, passenger's side floor and reach all of the tires and battery terminals. They opted to use the less common “Japanese-Style” connectors so don’t expect to use other devices unless you replace the connectors or buy the same style which can be found at McMaster-Carr’s website. I wish the storage bag was better (or preferably a hard case) but I’m not going to lower the score for that. I’ve used it 25 – 30 times now and it has performed very well and I was very surprised at how much improvement airing down the tires makes, especially in snow. We were on a mountain trail on April 29th 2018 and there was an unexpected spring blizzard resulting in around two feet of snow at higher elevations in the Adirondacks. I aired the tires down to 15PSI and chewed right through the deepest snow even when the undercarriage was dragging.
