HOW to seat stretched tires?

i tried to mount some 235 40 18's on my 18x10's and i couldn't get the beads to seat. they just seemed too stiff to stretch out far enough. they were dunlop sport max's.
i used the ratchet strap in the middle and it didn't even affect the sidewalls, it just crushed the middle of the tire down.

ridiculous amounts of lube on the barrel of the rim and more air? that should be a fairly easy tire to stretch size wise. The dunlop sidewall is somewhat stiff but not impossible.

yeap, lots of lube, lots of lube. and you will need a compressor that can shoot probably a good 80 psi to get those suckers to seat. now its a matter of how good of a compressor you have. yeah i just had a shop throw on some 225/40/18 onto 18*10

goodluck

sit the tires out in the sun and use a cheater tank

This helps sometimes too. Or, you could use the starter fluid method.

starter fluid, a lighter, and some balls

lol @ starter fluid. i've done that actaully but for off road big knobby tires! never had to do it on a car tire before. 

i may try some higher air pressure. the pressure at the tire mounting machine is regulated, so it probably isn't enough.

i wish i had a cheetah tank available here,  i'm sure it would do it.

yes, this method works as well.  
isnt there another type of fluid that can be used as well. ether or something like that.
ive been wanting to try it myself. but am worried that i will damage my new rims.

Do you have a line from the compressor you can run? I forget what out machine is at but it is significantly lower than a line straight from the compressor. Also, make sure your needle is out of your valve stem.

All else fails... starter fluid or whatever  that is around and ignites...

well.... i can use the standard air line that i use for tools. the comrpessors are pretty far away on the 2nd level on the building, i dont' knwo what line pressure is at the air lines.
yeah, the core was out from teh very beginning, i knew it would be that easy!

Michelin made a new tire (Primacy) that replaced some of the old Energy MXV4s in some sizes.  Those are the hardest damn tires to get onto even a normal sized wheel.  At work we generally use brake cleaner:

1) Spray brake cleaner around the bead.
2) Spray a short trail out the sidewall.
3) Spray the brake cleaner at a lighter flame (to make a flame/torch) aimed at the little sidewall trail.
4) Have your coworker douse any remaining flames with water after the beautiful boom of beads seating.

I've tried the cheetah.  It packs a punch :D

hey Ian,

How much do you guys mount tires? 

does anyone have a picture of a 225 on a 10j?
