I like to buy and fit my own tyres. I like to chip my one wheels rather than have someone else do it!
For years I wrestled with tires on the garage floor, chasing the damn tire iron around wobbly style. A few years ago I got a discount offer on a stand that I bolted to a scrap bit of plywood (big round piece from a round house kit found in the basement of said round house). Goddam if it isn't much easier having the wheel secured firmly at waist height. It takes waaaaaaaaaaay less time and effort. All those years of wasted time and sweary words.
Yeah, been there, done that. My Eureka moment was when I got a Sealey tyre changer that bolts to the floor, along with the correct tyre bar for use with ali rims. It even has a really good bead breaker built in. It's not as foolproof or easy as a hydraulic one, but it beats the living crap out of chasing a tyre around a floor...
Mine doesn't have a built in bead breaker. I've got one that works better than a C-clamp though. It came in handy for keeping the bead down in the center of the rim while looking like a monkey trying to fuck a football (American football) in those pre-changer years.
I borderline can't even be arsed taking the wheels off myself If I find somewhere that does ride in/out I'm using them.
Used to use an outfit called Rubber Ranch. You didn't even need to ride in/out, he used to turn up and do the job in the company car park. (Had all the gear on board a big Transit style van and would do tyre fitting at track days etc. Unfortunately he moved down to Kent I think).
I think he's somewhere West Sussex/Hampshire way now - he fitted my last set of tyres last year in a car-park in Farnborough iirc.
