Growing up on a farm and even now going on road calls sometimes one has to make due with what they have on hand. Spitting on a valve stem helps a bunch getting it to slide into the rim. Heck when I was a teenager I can’t tell you how many times we fixed a tractor / hay wagon etc. tire with basic hand tools in the field.
Lol i was going to say spit on the stem.... Anytime i worked out in the bay at the shop, i kept the new stem in my lips covered with spit ready to put it in the rim as soon as that tire was off the rim. It was like an extra hand.
Every one of my guys could bang a 4 tire change over out in 15-20 min. That's car in the bay, 4 new tires installed, balanced, back on the car she paperwork handed in to me to finish up with customer.
My personal best was on an old 90s civic, 12m8s. Done. I was not the fastest, i had one guy who was big and slow, but he could pick up the pace to install tires when he wanted. Lol just over 11m.
I get so frustrated now taking my truck to a shop and it's over an hour for them to do 4 tires. I started doing them in my apartment living room... Seriously.
On a side note, those push in stems are $28 cdn for 2...... Pricy up here. But better than a long walk
