DISCLAIMER: Possibility of injury or death. Do at your own risk. (How's that for a disclaimer?)

I've had a few people PM me (some registered on this forum specifically to ask) how I got my tyres to fully bead.

First, your best bet is to leave the tyres sitting in a car with the windows up on a warm/hot, sunny day. This helps a huge amount on getting the rubber to stretch easier.

You need a Cheetah bead seater (pictured below), but this was only one of the two steps required to get them completely seated. Chances are, only one side is seating and the other is sitting on the bead, but not actually seating.



I have two methods that should work. However, keep in mind that every wheel is different and one tyre may stretch on one brand/model wheel in a certain size and the same tyre won't stretch on the same size in a different brand/model wheel. e.g. I've seen a 195/45/15 stretch on a 15x10.5", but this didn't work on a different brand 15x10.5"; there are limits. Each wheel has the beads setup different than the next.

Method 1)
After hitting it with the Cheetah, chances are one side completely seats. What you do next is drop the air in the tire to 30 or so psi. Then, take the wheel & tyre and put it on the part of the tyre mounting machine that 'removes' already mounted tyres (pictured below). The already fully-seated side of the wheel should be put closest to the metal swing arm. Use the machine to lightly push the already beaded sidewall towards the non-beaded side. It will take a few 'swings' of the machine to get the tyre to center, and finally have both sides to seat.



Method 2) Purchase a ratchet tie down used for towing (pictured below).



Follow instructions in the picture below.




Don't forget to air up the tyres (at least 50 psi) before driving.

Best of luck.

I don't recommend filling it up with 120psi to try to pop the bead on.

3 years to late. Stretch is on its way out.

Always been curious how you managed to get so much stretch on your tyres. Enjoyed the write-up!

Mine as well buy a can of brake cleaner, fill the inside of the tyre, trace a line w/ the brake cleaner after filling inside away from tyre about 10 feet, light it on fire, ????, fail and watch it burn, profit??

Don't forget about the step of putting your fingers between the bead and rim. It's as safe as this writeup is.

There's a reason why they put a warning imprinted on the side of a tire that says "Do not exceed "this" amount of psi while seating bead.

Ever seen a person hit the ceiling of a shop from a tire exploding? I have and it's not a pretty sight.

Breezy

Yes.

The both of you are right; I should put a disclaimer. Didn't think it was a big deal, since it seems many people put that much air in tires to get them to bead--even my very professional 'TireRack approved' shop did it many times for me, even though I'm their only customer that does this kind of stuff.

Can you elaborate on the likelihood of something bad happening? Thought that warning on the tire was simply stating that it could damage the tire, rather than explode.

I will remove the 'air up to 120 psi' bit in my write-up. It's not needed in most cases, anyway.

Breezy

Thanks for the heads up, fellas. Post edited.

shkursht

Well if anyone is going to do it this way use some high pressure make sure you use one of these when seating the bead.

Breezy

^^^ Looked up videos on YouTube to get an idea of how nasty of an accident you were mentioning. Although we're not dealing with truck tires, I'll pass on over-inflating to bead passenger car tires. Good thing I'm back into moderate stretch and don't have to deal with these tactics any longer--it's a pain.

This video is unreal. (graphic) Yes, I do understand he should have been using a tire cage.

amptramp

I don't get it - what possible benefit do you get from this kind of tire stretch other than to ensure that if you slide into a curb, you rims will get bent and your tire will come off the bead? This should go the way of hellaflush, another bad idea based on the wrong way to get handling. Both ideas degrade traction from the stock condition and are more dangerous than stock. I could justify going the other way, putting on a larger tire than would normally be fitted to the rim, but only in one size increment, say going from a 195/50-15 to a 205/50-15, but tire stretching is lunacy and dangerous lunacy at that.

Just add soy sauce.

Does it really need to be said for visual effect? Obviously this isnt for a functional setup. With everyone in the helaflush seem starting to look the same, you start doing things to look different, more extreme.

Priceless and well spoken.

I have 225/45-15 on a 15x9 wheel which actually mount with a slight stretch and I truly and honestly hated the look until I got used to it.

I'm surprised no one mentioned how unsafe using a ratchet strap is to bead tires. That's the first thing I was told not to do in autos because theres a chance the strap might snap off under all that pressure and go flying.

Instead of getting a bead seater (which is the better way, but this is the cheap way), you can also make a frame out of boards/cinder blocks, put just the tire on the frame, and get one side to mount by pushing down on the wheel, and then follow the rest of your instructions.

This isn't as much of a stretch as yours, but this is a 155 on a 7" wide wheel.

First off, I AM a tire installer. I've gone to 12Opsi to seat multiple wheels. From big mudder tired to my personal 205/40/17 912's on 17x8 steelies. And obviously I'm still alive. Just use the cage with the automated psi machines, and stand way back. Let everyone else who is in the shop know what your doing and to stay the fuck away.

Do you know why the drifters 15 years ago in Japan were all stretching thief tires? It wasn't for aesthetics. It was to stiffen the sidewall of the tires. It helped give way more driver feedback, and so on.

Don't start bashing tire stretching threads. They are perfectly safe (for the most part. Breezy sorry to say but you stretched way too much and it looked like a shit satan would take) I ran 195/45/15 on my 15x9.5 with no problems.

On a list of things to be concerned about, I would rate the super slammed "broke my windshield cuz I hit a bump" cars WAY more of a danger on the road. Let alone any run down miata with blown shocks, worn out brakes or super blinding china made HID's in scatter lenses.


Now take this arguement back to the bar where it belongs

I'm not a hellaflush guy but I enjoyed the article. Too much hate in the comments though. Jelly perhaps?

That was the first thing we tried in auto shop at my school...well the very first was the brake cleaner and fire thing, then the ratchet strap...I stood out of the shop during both times lol.

Tylerq219

Why the fuck would you brag about being a tire installer?!? You must suck at it cause I've been working on cars for yeeeeears and have never had to fill a tire of any size to 120psi.

Maybe wash cars instead?

calm down internet tough guy. every tire is different, as is every wheel. rims have different profiles on the inside (and since you've been working on cars for "yeeeeeears" you must already know this, right?) and even with sufficient lube, sometimes they wont pop. even if you can air them up, the tire wont properly seat, and you can end up with a bit of a notch in them. sometimes you can use a deadblow hammer and hit the sidewalls around the part that hasn't popped yet. but sometimes you just have to add lots of pressure.

my 17x8 cragar steelies needed over 100psi to seat the falkens on them. when they finaly popped on there it sounded like a gunshot. all inside the cage (with the safety bar installed) and with a remote digital tire inflation machine.

car wash instead? no need. your mom keeps my cars pretty clean already
