I have a HFT manual tire changer. I enjoy DIY automotive maintenance. After seeing a plethora of KZbin videos about modifications to it, and after many frustrating attempts at using the damned thing, I decided to just scrap the damned thing and use some hand tools that get the job done much easier on just a flat surface or desktop (or even theoretically changing a tire without removing the rim from the axle): 1. AME 71600 "Little Buddy" manual bead breaker. 2. Tire Bead Clamp Drop Center Tool (total of four clamps works best) 3. Tire levers (from HFT, total of 3 levers works best) 4. "BeadBuster" Tire Mounting paste (works better than liquid stuff or dish soap) 5. Thin plastic rollable kitchen Cutting Board (cut to 2-inch strips to protect rim from tire levers) 6. 5-gallon Air Tire Bead Seater Blaster Tool. The key to ease and success is to take advantage of the "drop center" area of a rim. The bead clamps ensure this gets done by pressing the bead down into the drop center area. Then the job is easily done by prying the bead one lever at a time, one inch at a time, until it seats completely. The air blaster tool works perfectly for thick ply truck or Special Trailer tires that are too stiff to simultaneously grab both sides of the rim surfaces, forcing the tire bead to contact the rim and seal up nicely. I save a lot of money from the investment of these tools and doing my own tire changes, because I have a fleet of 12 vehicles in my household and I enjoy online ordering from Amazon or TireRack for my tires. My next investment, after I get my next Stimulus Check, is an electronic tire balancer, just like at the pro tire shop, because the HFT manual balancer is not precise enough for the fastest cars in my fleet.
@chrisbergeron56253 жыл бұрын

Good video. Most folks don't know about the drop center. Also you know this, but there is only one correct side to remove the tire, as the drop center is typically not centered on the rim. At least in modern wheels it's not. I like that paste lube your using, as it leaves very little water vapor, which accelerates the corrosion of aluminum rims. That whole nitrogen thing is wasted if there is water vapor inside the tire. I've not seen that lube available in the states. I typically use a bar of soap, rub it on dry, and that works very well. But I do see micro bubbles and your sealant would be a good thing as it's not messy.

I'm not too worried about scratching rims, but I did my own modifications. I welded some old bolts to the bead breaker to make it more sturdy, on tough beads it will bend and slip off. And the holes where the pins go through I welded some washers to make them stronger. Also the pipe that holds the bead breaker is slighty too long and needs grinded down. Works so much better now, If I get a new one, It'll be the first thing I do.

I saw another video where in the comments someone said the coloured dots, (yellow/red) printed on the tyres were meant to go at a certain position.

Yes, but not all tires are marked this way. Somebody else left a comment, under my balancing tires video, that he turns the tire on the rim to find the right spot that will require fewer weights.

The best way to prevent damage to the tires is to use proper technics! In all honesty there's no work around from it! Do it right and the probabilities of a miss happening, like blowing a tire basically vanish. The always and the never tips: - ALWAYS inspect a tire before assembly, even a new one! If lacking knowledge at least apply liberal amounts of very rare common sense! LOL 😂 - ALWAYS lube the tire, rim and eventually the tool tip! More on this in a second. - NEVER overinflate a tire! If you feel the need to do it. To seat a bead, etc. Please understand you're doing it WRONG. So step back and start it over again. ;-) About lube, the subject was not properly covered. On this otherwise very good video. But keep in mind ALL tires should be lubed in three (3) areas! Remember this number. They are respectively, both outer beads. AND the upper inner bead facing down (facing the rim)! This last one is probably the most underrated detail... Now let's talk about lube the RIM. Also three (3) areas! Upper outer lip AND both bead seats. With this properly done, pretty much all tires will be really easy to do. BTW it's worth mention, that it's much faster to do it, than write these details! Becomes a second nature. This week alone I set a few tires on steel rims and alloy rims. Some, even on the steel rims, seat the beads with as low pressure as 10~12 psi! The type of lube also play a roll. These very low pressures were accomplished with "hair spray" used as lube! Yes, normal (cheap) hair spray the ladies use to fix the hair. Exactly the same tires and rims set. assembled with soap, saw the pressure increase to around 25~30 psi. Both using the same lube technic as described above. Cheers

Samples of the original units are held in the National Institute of Standards and Technology www.nist.gov/ This means, that the imperial system used in the US of A is based on the metric system (SI).

@@robertdeptula2003 -- I'm an engineer (retired)... I am well aware that there are exact conversion factors between the US and metric systems and that it is possible to derive many through the memorization of of a few base constants... For example, if you want to convert from liters to gallon EXACTLY, you just need to remember that there are 231 cu-in in a gallon, 1000 ml in a liter, and 1 cu-cm = 1 ml -- it gives you 3.785411784 liters per gallon EXACTLY. That's the US gallon, not the Imperial gallon... My impression from spending some time in the UK though was that they use a mix of metric and Imperial for various things. For example, road distances will be measured in miles and distances to a near highway exit in yard, but bridge clearances in meters... Most weights are quoted in kg, but people tend to quote their weight in stones and pounds... There is nothing magical about the metric system like uninformed proponents that you have you believe... It's just another arbitrary system of measurements, albeit with unit conversions based on powers of 10...

Why can't you change an 18" wheel/tire with these low cost tire changers? Most of them say 16 or 16-1/2" maximum size.

What’re the pads you used for the bead breaker

Few years ago I bought it on line as a replacement part for different tire changer. Don't remember the name of the company. Can be easily done. A chunk of plastic can be bought at local supplier, same as the white plastic I bought for the changing bar.
