Did my first tire change

So I did my first tire change by myself. Have only been riding a few years now and always had the shop do the few tires I've replaced.
I chose Motoz Tractionator Enduro soft front and rear with ultra heavy duty tubes. Thanks Marty at BRAP Offroad and Kelly for the referral.

I did ok. I went by a Dunlop YouTube video. I found out today I guess I pinched the first tube I did for the rear tire. It lost 7 psi overnight so I guess i will be replacing again. Should I patch the tube or replace it?

My biggest problem was setting the beads on both tires. Each time there would be a section of bead on each side of the rim that wouldn't seat. It would be buried in the rim. i used tons of soapy water, spoons, but eventually got them on after fighting for a while. I pumped them up as high as 35 psi to set the bead.

What was I doing wrong? Am i the only one having these problems? Safe to patch the $37 tube or should I replace it?

I personally just replace the tube. Makes me fell better. You definitely do need to over pressurize to seat the bead , then adjust for proper riding pressure. That and- the more you do the easier it gets.

Replace the tube. Next time inflate and deflate several times at slowly increasing pressures. This will allow the tube to find its place within the tire without pinching itself between the bead and the rim. The last time inflate it a little above the pressure you want to run and deflate down to that point. Patches are a fix to get you home until you can replace the tube. Replace it with a HD tube.

I use wd40 on tire installs and If the tube isn't between the iron and the rim and you don't bring the iron past 90º when installing tire you can not pinch the tube

Take the valve out when you seat the bead.

Using ultra heavy tubes are harder to replace than light duty ones so you probably had a "worst case scenario"

Rather than soapy water, use liquid dish soap full strength. Put some on your finger and lube the bead. This type of soap has two actions. It is a superior bead lubricant and then glues the bead in place after it dries. Every glued a bar of soap to the counter? Works very well. Some heavy carcass tires can be harder to seat the bead than others. Changing a tire is not hard to do and practice makes it much, much easier. I will have to watch that video and see it they are doing it right. There a couple of small tricks that make tire changes much easier. Cam.

Thanks everybody for your advice. I'll try some of the suggestions.

Here is the video I went by.

I think it was the valve core on the rear tire. It held pressure today.

Now my front was low this evening. Tightened core and aired it up and will check tomorrow. Hopefully all is well.

Thanks again.

I never use HD tubes I think they are a PITA and add unnecessary weight. I have never had a flat in thousands of mikes of desert riding.

Now I will probably have a flat tomorrow. I do carry a spare tube.

I prefer hd tubes for changing if in an ideal environment like workshop but keep the light duty ones as spares know the pack for when riding.

Some of my practices based on what I've read here, just the stuff that works for me:

I never pack a tube that has a patch, I've done that before and the patch will not survive in the pack. A patch has the greatest chance of staying on when it's installed in an aired-up tire. I always run my patched tubes and pack my new tubes.

On the trail, I always try to patch a tube if possible, saving the new tube in the pack as a last alternative, like in case the running tube gets ripped beyond repair (see pic below).

I don't use HD tubes, I get the cheapest tubes I can get, $15 is par for what I like to pay. I've run one rear $15 tube with 3-4 patches and a rusty valve stem for over 1 year and about 6 tire changes before it got retired from a split under a patch (see pic below).

I quit using Slime, I never had a puncture fix itself with Slime, and the Slime hinders my patching.

I use good quality bicycle patches with feathered edges, I've had the cheap patches get peeled up from the side.

I use patches. Generally I replace the tube with my spare if I use more than 2 patches. Then the patched tube is the spare. I have never had a patch fail. Actually I haven't had a flat in years. The patches mostly go on my friends bikes. Cam.

ps I once had 17patches on a tube. That was when I was first learning how to change tires and hadn't learned what tire irons where. It was screwdrivers or nothing.
