I was asked to mention my time there. It was a business started/owned by two brothers-located in what is now a third ring suburb of Minneapolis. Population then as a mostly farm township was probably 3-4000. Likely 20 times that now as it is fully developed into a higher income city. The building stood alone on US Hwy 169 across from the Northrop King research testing fields. The main line was Goodyear with others for lower $ options. We did cars up thru 18 wheelers(I remember us 'locking' the air chuck onto the valve stem on the split rim wheels and then jumping behind a wall-if 'things' weren't right, that 'locking' ring could do alot of damage-later we got a bright red steel cage to air up those puppies=much better!). What made this business different from most was the customer site work done at a long list of area auto dealerships. We had a small fleet of 5 or 6 Chev stepvans outfited with a compressor and Coats 10-10 tire changer-also a floor jack and bubble balancer and some tire inventory. A sales guy and his 'flunky' would pull off the worn out balony skins off used car trade-ins and install recaps on the low end and first line Goodyears on the high end trades. I left in 1970 as the military was after me with a low(bad)lottery number. Later, over the years I would drive by occasionally and notice the building expanded a few times. I stopped in there a few years ago as I noticed a Toyo sign and I was driving my wife's Nissan 350 that has Proxies that I wanted info on. The place was dead with no customers and I was met by a big unfriendly fella who said he'd 'bailed out' the brothers buying it as it was about to go under shortly ater he arrived from Iran. Oh well!
