I mount my own motorcycle tires.  I was wondering how much harder it is to mount car tires.  I was thinking that I don't care much about the pretty rims on the _inside_ of the car, so some things would be easier than a motorcycle.  Seating the beat could be tough.  How many SCFM do you think you need to seat the bead on a car tire (maybe 10?)?  Would putting a ratcheting tie-strap around the center of the tire help it work with 4 SCFM?

some rims and tires can be hard. when I used to work at pepboys we used to get some truck tires even our mounts cant do so you may or may not be able depending on the car.

Rema:

Yep, use a ratcheting tie-down to force the beads against the bead seats.  A little bit of seat lube or a solution of dish soap and water will help.

Changing car tires with steel rims is easy if you have a set of bars.  I'm not sure why you'd want to when my local farm store mounts and balances for $3 each if you buy the tires there.

Take the valve core out of the stem when you seat the bead.  The valve core is a fairly large restriction.  Be sure not to exceed the seating pressure listed on the sidewall of the tire.

Now for one of Kasumi's legendary and rather useless posts vaguely related to the topic but still unhelpful lol.


How do you get a tractor tyre onto a tractor rim?

Well quite easy if you know how, you would think thats gota be impossible, the wheel on some of these bigger tractors sits way over even a tall mans head how could you even find a machine to do that. Well the answer is its not very common round here, even our local agricultural companies don't have a big enough piece of equipment.

So..... we blow it on. You lay the rim on the side, lay the tire ontop and leaver the first edge onto the rim  so now the tyre is half on half off. However you have no chance of getting the other side of the tyre on because theyre too big too heavy and took awkward. Answer - lighter fluid. Take one small bottle of lighter fluid and spray generously into the tyre aim for the side which is already over the lip of the rim. Now as it evaporates the gas collects in the tyre. Now drop a match in there  BOOM! and your tyre is now nicely seated onto the rim and you just inflate as you need

Ether works Better.

yes either and lighter fluid both work nice for seating the bead.  But you have to remember to let the air out after you do it or else the gases created destroy the inside of the rubber.

Tubeless tractor tires?  Seriously?

Where the hell have I been?   

Not sure I'd want to try that with a car tire.  I tend to use too much ether.   

Where have you been    I havn't even seen a tractor tyre with a tube lol

i have 

I don't quite get it.  I can imagine that if the tire on, but not seated (both beads between the left and right edges of the wheel), then making something go "boom" inside the tire would seat it.  But if the tire is half on (just one bead between the left and right rim), and you make a "crontrolled explosion", I'm not sure how that would pull the other bead down in between the wheel edges.

I called three shops to get tires mounted; the neighborhood one said "come in a week from Friday" and the two tire franchise shops said "call us next week and we'll make an appointment for the week after".  I guess everybody in town needs the same thing, and I'm sliding around on summer tires.

have you tried your local wal-mart?

Simple physics'
An object in motion want to stay in motion.
An object at rest wants to stay at rest unless acted upon by another object. 

The expanding gasses from the ether explosion force both sides of the tire outwards.  the rim "catches" the bead ,if you must, and holds it in place.  Once a tires bead hits that lip and forces itself into position it wont settle away from that unless you but weight on the tire before you inflate it.  Plus the hot gas has expanded filling the empty cavity maintaininga little bit of pressure on it.
