i'd like to update this becuase i got new rims. For asummary i ran 80z bnags in each of my 33" tires on 15x7" rims. WEll i had my 15x10's installed and made sure no beads were spilled...there wasnt any we checked religiously. Mounted the rims and i went on the highway. at 40 mph i started to feal a vibration and it got worse the higher i went i got to 75 mph and the truck shook violently, like i couldnt hold the wheel and it started to swerve a bit. I had to got to seattle the next mornin at 5 am and its already 12:30 am so no shop is open. I drive to seattle at 60 mph and take my truck for an oil change and ask them to remove the beads in the tires and put static wieghts. I went on the highway, 70mph no vibration, 80 mph no vibration, 90 mph no vibration ( istayed a t 90 for about 30 secs). the vibratiobn were all gone, all i felt was the bumps in the highway. I was afraid i would have to just unisntall everything if the tires made my mounty ride like that and i couldnt go over 70, but now i can. SO my new opinion on tire beads is that they are not made for a 15x10" rim, i dont now why it would be different but it was tooo dangerous for me to figure out why.
