put a tube in my 250sx rear tire, bead won't seat on one side but holds air fine.

[kilabeez0]

The side that won't seat was a HUGE PITA to break in the first place. 2 pickup trucks, 1 on each side of the rim and it still wouldn't break . Sprayed it with some rust penetrant and did it a few more times for it to finally break. So anyway, got the tube in and now that side won't seat. 1 little section seems to be ok but the majority of it is a solid 1/2 to 3/4 inch off. I aired it up to 17psi but I'm scared to blow the tube as it's hard as a rock and I'm not sure what it can go up to. I put the wheel on and rode it around my back yard and took it off a little jump a few times but no luck. Any ideas?

The tire should be marked with running psi , and psi to seat . Not sure how a tube would effect this , but would guess it would increase the pressure to seat .
I would have to say 17 psi isnt enough to set the bead .

Be careful

35 psi or more sometimes on atv tires... As noted the tire will usually say 'do not exceed xx psi when seating the bead'. Dont be skeered lol... all these threads but not too many about blowing a tire apart... I go to 60 psi sometimes on motorcycle tires.

A fun fact... many new car tires are built to take almost 200 psi before they blow apart. Obviously cracks and wear are a factor.

There have been many times I've had to put upwards of fifty psi in atv tires to seat the beads. I'm just glad I'm a mechanic with a shop full of the proper tools to do tires, lol! Let the air out of the tire, spray some soapy water on the bead, then re-inflate. Just be careful when airing it up. I don't care to stand too close to a tire when I've got all that pressure in it when seating a bead. If you have a trigger operated air chuck that you can clamp on to the valve stem, then squeeze the trigger (so you can stand fairly clear of the tire) that'd be best.

use a 2" ratchet strap tighten it a bit on the center of the tire. put some dish soap on the bead that is giving you trouble. the strap will keep the tire from stretching out and put more pressure on the outer side's of the tire. this system works good for me. but still be careful place towels sheets etc on the metal parts of the strap in cast of breakage this will slow the flying parts down.

Ratchet straps are great, but ive seen them explode and do serious damage while seating a bead more than a few times. In all my years of seating tires on bead i have never once seen a tire explode.

That being said, i use ratchet straps as well. And ether and fire, lots.

A lot of you are missing the point that I installed a tube. So pumping a regular tire with 60 pounds is totally different. I've done that with atv tires as well however this has a tube in it. The tire itself says not to exceed 7 pounds lol so I'm hesitant with the tube at 17 as it's hard as a rock.

[atc007]

Break it back down. Or take it to a tire shop. I am assuming you are dealing with a used tire/new tube. I HAVE exploded a Dunlop 22/11/8 in my face. And it wasn't a great experience Used tire I had patched. Cleaned the parts off the shelves 20 feet behind me. Anyhow.. The tube won't blow unless there is a tiny little something in there ti pop it?! It should break back down very easily. Put PURE soap,or oil,on the stubborn spot. It will seat. But if you're this uncomfortable, I would seriously consider paying to have it done.

I've done the ratchet strap trick to seat a bead with a tube in the tire.

spread some dish soap around the bead and bounce the tire like a basketball... sounds dumb but it worked for me before.

+2 ^^^ except I use grease when doing all my tires.

You don't know scary until you are seating 20x7-10 Razr MX on 7x10 stock rims. That took 51psi and two ratchet straps.
Or a set of 18x10-8 Tamers on 8x8 Champion beadlocks. That took 48psi in one tire and if you don't know the beadlock you don't know what it's gunna react like


But yea. Break the tire down, a little scotch bright work around that side bead and then smear grease all the way around the rim.

when I put a tube in my yami 200 I had a used tube used tire 59 psi and a forklift to get it so seat man was that thing an ass.....

[atc007]

You guys are scaring the crap out of me.. My Brother in law had a truck tire go off on him. Turns out ,a 16 inch tire wouldn't go on a 16.5 rim... Lucky,lucky man.. I am NOT a fan of ratchet straps at all. Never used them, and I've seated tires from 30.5 32's down to wheelbarrows,and thousands in between. never used a strap. Lots of bouncing/pumping,but no strap. I can just see that thing giving way into my eyes. Not for me.

I use a tire chuck that clamps on to the valve stem so I can put the stubborn tire outside the garage and shut the door. I control the air with the shutoff valve on my compressor. I havn't had one blow but doing it like that if one were to blow I would only be out a tire/tube and not body parts.

I can assure you the tire does not say not to exceed 7 psi when seating the bead. That's the max running pressure. All the advice here still applies when using a tube.

If you are still scared, Air it up, let it out, lube it, air it up, let it out, lube it. atc007 mentioned bouncing the tire, that works for the less bold as well.

The thing you have to realize is the tire is taking the load, not the tube. The tube is just sammiched in there.
