Depends on what's wrong with it, what you have available, and what kind of valve it has. Usually wheel barrows use the same kind of valve as on car tires, so if you have a pump or a compressor to inflate your own car tires you can easily inflate the wheel barrow the same way.
Take it to a place that sells tires. I took the wheel off of the wheel barrow and took it to Discount Tire. They have this tank of compressed air that in one loud moment shot a huge amount of air in between the tire and the rim. If made the tire seal to the rim instantly. They didn't even charge me a thing. From now on, I make sure I have a very full tire before using my wheel barrow.
Usually the problem with a wheel barrow tire is the wheel rather than the tire. That is a poor fit between the rim and the tire. You need to take a strap and tighten it down around the outside of the tire and then inflate the tire so that it grips the rim tightly.
35 PSI.
You will destroy the tire and harm the bead seating surface on the wheel.
Yes, the air can leak out of the crack.
Maybe a mile or 2 to get you to a place you can get a spare. Driving on a flat tire can cause damage to the wheel and possibly the drum and brakes. If you must drive on a flat tire, drive very slow and stop if the tire comes off the rim.
If you suspect a flat spot on a tire examine the tire closely. You should be able to see a flat spot. To determine if your car has a bad wheel bearing rotate the wheel. A bad wheel bearing will often make a grinding sound as well as feeling rough as you turn the wheel. A bad wheel bearing may also shake or wiggle. It will also cause a car shaking problem.
You need a jack and a wheel brace (wrench)
Did they balance the wheel when they changed the tire? The other thing that may be off is the tracking, especially if you drove for any distance on the flat. Get theses fixed or your tires will wear unevenly.
There is no space for a spare tire if you have AWD. That is why factory provides the Run Flat Tires.
this is a funny way to answer do yo feel the vibration in your but or the steering wheel. If its in your but there is a problem in the rear wheel assembly, ie bad belts in a tire, wheel bering, flat spot on a tire tire out of ballance
