Thanks to this thread, I'm revising my answer to $0
OK, so $50 for the tire irons, $75 for the balancer (FM Mark Parnes), $30 for the harbor freight bead breaker (works perfectly) $7 for the rim protectors and $15 for a lifetime supply of tire lube. I think I'll be leaving the tub to someone in my will!
Did my first tire a few weeks ago. Now I just need to figure out how to better protect the finish on the wheels.
The rim protectors I bought didn't do squat... in fact, they didnt even want to stay in place.
Did one tire so far, have at least 5 tires to do this year... by the end of summer I'll be making money off the purchase.
