I change these things myself all the time. I use a couple of HUGE screwdrivers, a medium-size sledge, & a mattock to break the seal (looks very similar to the official tire tool used in "real" tire shops) believe it or not. If the old tire is "stuck" on there it can be interesting & sweaty to get 'er off. While inflating, I wrap several loops of heavy chain through all of the holes in the wheel and around the tire. My opinion is, if it holds while being inflated you are home free. -Also, ANY tire shop worth a hoot should be able & willing to change these. They are true wimps if they refuse... really they're not all that scary if you take reasonable precaution. Call if you want pointers on doing it! -John, Reno NV 775-722-2955

Stovebolts are like women; as they mellow with age, it's harder to get 'em to turn over on a cold morning, but once they're warmed up, LOOK OUT!
