well i got a hook up on some used vette tires, 275/40ZR18 Good Year Eagle EMTs (extended mobility tire) i can get them to inflate and seat but after i inflated them the outter bead just slid back down the barrel and didnt stay seated..

are they too stiff to stretch ? or do i jsut need to leave them inflated longer before i adjust the pressure?

oh and i am putting the 275/40s on some 18x11.5" wheels if that helps

inflate them to like 90 psi and let them sit for a couple days

thats best bet

i had potenza re050a's on my old s13. all we needed to do was cheetah them on, and it worked fine for me.

haha 90psi? im not trying to get killed by the tire....

like said i can get it seated but if the pressure is below like 30 psi at all, the front bead slides back lol
the only reason this is bad, is if i end up with a flat my wheels are f**ked..

any one else on here run EMT/runflats?

Those Eagles are sooooo freaking stiff. They might need the extra psi and time for the sidewalls to conform to being stretched. I remember mounting some of those Eagles. They were a BITCH!
