great video Pablo, if you take the tire off completely, the weld will create air passage once is dried even if you sand/smooth the area down. best way to do it is let out all the air by removing the stem valve with a stem removal. pop the area the is leaking with a sharp plastic/common screwdriver, to allow clearance to paste the weld in the area. once the area . put the stem valve back in so the tire will put the paste into the crack area as well as seal the area. do the outside area with multilayers of weld. let it set over days because the thick layer of weld will longer to dry completely. after 2 days, apply air to half of the tire pressure and wait one more day to the full tire pressure. use soapy water to check for bubbles leak. if no leak check the tire pressure again the next day to see if tire holds pressure. once repair, install the welded rim to the rear axle, not the front axle since the weld will cause balance change due to added weld on one side of the rim. check tire pressure before daily drive to be safe. better install the welded rim at the left rear side so you can see the tire condition before driving car. i'm using JB weld on lot of home repair and used it on rim. so far it holding. i would not rely on a long distance road trip ( better for local trip ) for unforeseeable event of tire failure.
Good tip is to take some plastic and cut it with a scissors to match the mould of the rim and use it like a spatula to wipe off the jb weld and sanding is easy 👍great video though
Yeah I have a set of rims outside on my back porch it needs a bit J-B Weld as well I have been spending so much money over the years fixing on vehicles that I drive and nobody is really getting it done for me period so I took everything into my own hands and fix everything myself. Guys like you are very blessed for showing others that they can do a job on their own vehicle for a little of nothing less time
Thank you very much for watching the video and commenting I’m glad I was able to help never hurts to try and save some bucks if you like what you see you are welcome to subscribe thank you in advance
Hi, thanks for the video. I did this repair on my Mercedes 22" wheel, and even drilled a hole in the end of the crack, but after 2 weeks and a drop in outside temperature to -2 , the rim recracked. This is purely a temp fix, for a permanent fix you would have to weld it or replace the rim.
I repair wheels for a hobby and did EXTENSIVE research on wheel repair (I’m also an engineer). I don’t recommend anyone do this method to repair their *cracked* wheels. - You should ever only consider repairing hairline cracks perpendicular to the grain of the wheel, and typically only on the inside. The face/spoke side carries most of the load, though excess camber does put load on the inside too. - You need to cut out the crack (preferred) or drill a hole in front of the crack to stop the crack from expanding, which it almost always will if you don’t do this. - JB weld has a tensile strength of 5020 PSI but that doesn’t really apply, since you’re going to be using such a thin layer. Try making a thing sheet of JB Weld and hit it with a hammer and see how much force it takes to break it. Now imagine doing that with the force of a car. - For curb rash repair, JB weld or metal reinforced bondo is okay. JB Weld is stronger than bondo, but harder to sand. Always start with a lower (100ish) grit and work up (I usually go to around 400-600). - Welding the crack will always yield the strongest and best result (next to just buying a new wheel). I hope this helped you guys, try not to spend $10 on something that is critical and towing thousands of pounds of metal that is capable of going hundreds of miles an hour. That’s like using duct tape instead of screws and bolts to keep a rocket launcher together
Tengo una pequeña fisura en un rin de aluminio queria hacer un taladro al final de la fisura , con una muela desbastar en v la fisura y aplicar jb welb crees que se soluciona?
As a hobby is good enough, to actually perform like it never got cracked is almost impossible, that crack is going to Open and close and that’s where you will lose the strength of the JB weld
genesssisss You right I just wanted to try it and I still have them on no leaks yet lol btw Thank you for viewing and commenting you are welcome to Subscribe if you like 💯🤘🏽
I have repaired thousands of wheels Used this before you hit a bump and this is just a patch It will break right off Have it welded correctly Is the best and maybe use over a legit aluminum weld
you may have repaired thousands of wheels but I don't understand you do to lack of grammar. Having it welded correctly is best, and maybe use over a legit repair? use what over a legit repair? whats the best having it welded or not?
I still have them I’m running fat tires I’m pretty sure if you running stretch tires it may not work because of the impact is strong when you run low pro tires with stretch
I will run on 255/35R18 on a 8,5J rim (oem size). I dont have that product in France, i bought an epoxy glue, very strong they say. I have a little crack, half of yours but in the same place. Do you think that may hold up ?
