I just got 4 new tires and tubes,started changing today after finally got one done blew it up it sat for about ten minutes and tube exploded I must have twisted it for it to do that,so I put another new tube in and couldn't blow it up took it back out and I pinched it with spoon. I just watch a video where they put the tube in before it was on rim,anybody do that,I have changed many tube type tires but never heard of putting tube in before its on the rim

You should specify tire size.
Guessing 30 x 3.5". 21" is a different game & way easier. Clincher vs drop center.
I Always put the tube in first & inflate a bit. Talc/baby powder in the tire before putting in the tube.
Put BOTH edges in the rim @ the valve stem & work them together into the rim both ways until across from the stem.
Be really careful where the spoons touch the tube & tire. Don't pinch a tube. Use a tire lube & long, Harbor freight type irons.
I have not seen a decent or pertinent video of an install with clincher rims.

Yes tires are 30x3 1/2, so you don't use flaps and pry on both beads at same time?

Tire mounting is one of those topics that one has his or her own technique. Personally, I'm a flap guy & one side at a time being's I'm going on 70 & my knees won't take the floor anymore !

Flaps should be used for split rims. People have opinions with regard to flaps and clincher rims.

I did not use flaps to mount four new tires and tubes on good clincher rims.
I used talc on the first one but found I didn’t need it since I warmed up the tires in the sun first.

Put the tube in first inflate the tube (low amount of air) just so it doesn’t have any wrinkles. Now put your flap in being sure to fit it on both sides of the tube. The flap should not be bulging out locate the valve stem, pinch the tire sides together where the stem is and insert it into the rim, now work the lower bead over the rim using your spoons. The flap should help you from pinching the tube. Once the lower side is in start working the top bead over the rim with your spoons. Once the bead is over the rim check your valve stem to make sure it’s straight & not in an angle. Inflate the tube a bit more making sure the beads are locking under the rim edge. Once you get it there inflate to 45lb. This is where I’ll inspect the edges and use a rubber mallet to make sure the tire bead is catching under the rim edge. If I’m satisfied I’ll air up to 55 looking for any problem & trying to listen for the pop as the beads are locking in under the edge of the rim. If all is good I remove the the Schrader valve a bit and deflate the tube then tighten it again and inflate to 60lb. Some folks use talcum power, some use plastic garbage bags but I’ve had no real issue not using either. Your mileage may vary. Best John

Great explanation there, John !

From personal experience, it is substantially easier to remove and mount a clincher tire with the wheel on the car instead of the wheel or demountable rim on the ground or a bench, etc.

If you have demountable rims, move the rim to the front wheel if necessary as there is more room under the fender.

Also, regardless if you have clincher tires or straight side tires and split rims or drop center rims, the primary purpose of tire talc is as a dry lubricant to prevent the tube from chafing against or sticking to the inside of the tire. You don't need much tire talc dust the tube/inside of the tire.

Finally, if you purchase the long thin, Harbor Freight tire irons shown in a prior comment above, make sure you check the ends and dress them with a file if necessary. I picked up a pair a few years ago and cut my thumb on the end of one of them.

John explains it perfectly. Tube, inflate a little, install flap, inflate a little more, then install on rim. Course I have it easy since I let Adam put my tires together on his tire machine, but that is how he does it.

thanks for all the ideas, I watched a video where the guy used a garbage bag over the wheel and used his hands and pressed both beads at the same time, I haven't heard here where anyone has tried both beads at one time,anyone ever try that?

I do both beads at the same time when installing a clincher tire, I find that the easiest way. But when I need to just pull the tube out I only remove one bead, replace the tube, and reinstall the one side of the tire. I never used liners with clinchers, but after having a blow out from a pinched tube years ago I now use liners for clinchers and have never had a pinched tube again. I find a liner helps keep the tube in place when installing a tire both beads at once.

The picture montage should be helpful to you.
Early on I used flaps on clincher tire installs.
Flaps do add a bunch of extra protection against pinched tubes. Without flaps, you have to be extra careful.

The garbage bag video method using only your hands is on drop center tires. (21" wires), not clinchers. Not the same.

I do install both beads @ the same time for all T tire types.

I have not seen a decent or pertinent video of an install with clincher rims.

When I first got into this game, like all new guys, I found mounting tires quite a struggle. Eventually I got into Model T travel, which means covering lots of miles. It also means an occasional need to change a tire. I guess practice didn't make me perfect, but it got me to the point where changing a tire was no big deal. If I ever have the opportunity, I'll make a video. Until then, I'll just tell some things that may help.

I prefer changing a tire with the wheel ON THE CAR. Let the weight of the vehicle work for you.

I agree with using HF two-foot irons. Little Ford irons make changing tires the job from Hell. Mister Archimedes tells us that a long lever makes prying easier.

Lubrication helps, but the lack of it isn't a major impediment. I use baby powder. Talc or starch? I don't care.

Procedure summary:

Jack the wheel off the ground. Position the stem at the bottom and lower the vehicle only enough to keep the wheel from turning.
Starting at the top, pry the tire (both sides) off the rim. Raise the vehicle and extract the tire.

Installing is easiest with the tube in the tire, inflated only enough to keep it in there. Again, the stem hole should be at the bottom. Put the stem in the hole and lower the vehicle only enough to keep the wheel from turning. Beginning approximately at the four o'clock and eight o'clock positions, pry the tire (both sides together) onto the rim. Inflate to forty pounds, completely deflate to let the tube find its position, and inflate to running pressure. I use 65 psi in front and 70 psi in the rear.

Did Ford use flaps? Neither do I. I do make sure my rims are excellent.

George is checking the wiring while I inflate the new tire. After trying various methods of inflating tires, I finally settled on a HF compressor and a 12 volt battery to run it.

With the tube in the tyre, levering both sides on at the same time, the levers have no chance of pinching the tube, Right at the end, one side may pop on first. Then you just need to be careful with the last little bit of the second side.
Be aware that flaps and liners are two entirely different things, A flap is meant to be used in split rims or in lockring type wheels to prevent the tube from chafing at the rim joints A rim liner fits the wheel base. It goes on the rim before the tyre is fitted. It protects the tube from rust flakes and imperfections in the rim.
Flaps in clincher tyres will protect the tube from clumsy use of tyre irons. However they add considerable weight to the wheel assembly, while subtracting a considerable amount from your wallet.
