People need to know local mechanics and tire shops. Not necessarily the big-name shops, or the shops with 10 techs, but the smaller shops run by "Joe" and his mechanic "Bob".
I used to have a racecar, and needed an alignment. Shop after shop replied with "it's not in the computer so we cannot do it.".
I got referred to a frame shop run by a guy called Jerry. I stopped by and there was nobody in the front office; I walked into the shop and there were 4 car stands (4 post things) with 3 racing trucks on 3 of them. I was in the right place.
Since then, whenever I need any tire / alignment stuff, I go and see Jerry. I "buy him lunch" every time I see him with a $20 handshake.
When my wife had a flat tire, he fixed it for free. The "Tire Store" told her she needed a new tire. Jerry fixed it, and told her that the other tire stioe didn't even take the tire off of the rim. Wife was "worried" that the tire wasn't safe - Jerry's WIFE told my wife that if he says it's safe then it's safe. The tire lasted 40K more miles.
I stop by and see Jerry every time I need something. (He calls me when he needs tech help on other stuff.)
He will rotate my tires. He will check my aligment. If the alignment is fine, he doesn't charge me.
I buy him lunch.
When I needed new tires, we had a discusson on tires, and what shape he likes and how they last. My "online" price was cheaper than his price. I bought the tires online, shipped them directly to him, and he mounted and installed everything. Charged me $20 per wheel.
Find a local mechanic. Talk to them and show an interest in them an their life. You will get good advice whenever you need it, and if they cannot help you with a proiblem, they will know who can.
