Its been a slow couple of days in the shop. When I don't have anything going on, I get to do other things outside the shop, like roadside assistance calls.
I get called to a flat tire call this morning. It was literally 2 blocks from the shop. I get there and procede to change the tire. It was on the rear of a newer Grand Vitara. The conversation went like this:
Customer: "I called your shop because I found out that I my car doesn't have the jack or lug wrench. I just bought this."
Me: Looks at temp tag in rear window. Its 2 days away from expiring. Its a 30 day temp tag. "Uh huh. Well I'll get the spare swapped on so you can be on your way."
Customer: "Thanks. I'd help you but I'm on my way to a meeting. I don't want to show up filthy".
Me: "No problem. I've been there before. It will take me just a few minutes."
I get all of my crap out of the response vehicle (shop owner's beat to hell Isuzu Trooper). I find an aluminum floor jack with only half of the handle and the world's smallest 4-way lug wrench. Greeeaaat.
I proceed to get the wheel off with the flat. It has a big gash in the sidewall.
Me: "Looks like you hit a piece of metal or something. The sidewall has a big gash in it."
Customer: "Yeah, the tire just went BOOM; scared the E36 M3 outta me."
I get the PITA spare tire cover off and notice the lug lock on the spare. Wonderful.
I have the customer try his ignition key in the lock. It works! What a lucky break!
I get the spare down on the ground. It's even aired up!
Customer: "Does the spare look bigger than the other tires?"
berkeley. Yep, the spare tire is 235/60r16 and the other four are 225/60r16. Its very noticable.
Customer: "Will it be alright to have two different size tires? Why are they different sizes?
Me: "Well, it will probably be OK for a short distance. I'd visit a tire shop TODAY and get matching size tires. Who ever owned this before you probably bought the smaller tires because they were less expensive than what the factory put on. In fact, let's look at the sticker in the door jamb and see what is the correct size from the factory."
Customer: Deer in the headlights look.
I go open the driver's side door and find the decal which calls out the factory tire size and pressure. Hmmm, 235/60r16. The spare tire is the correct size.
Customer: "I didn't even know that was there!"
I continue to swap the wheels and show the customer the factory jacking point on the frame so he won't kill himself if he has to do it again. Maybe. Hopefully.
Me: "Alright, you're all set. Remember, don't drive with this tire on for very far. Get a new pair of tires ASAP.
Customer: "Uh huh. Thanks!"
And then he sped off. I feel like he won't heed my warning and drive with mismatched tires until the diff explodes. And then of course blame the underpaid schmuck who changed his tire.
TL;DR: Clueless "professional" guy buys an orphan SUV with E36 M3ty, undersize tires. Proceeds to get a flat, finds "car he just bought" didn't have any tools necessary to change said flat. Calls roadside assistance. Spare tire is bigger than tires on car. Will probably ignore underpaid schmuck's dire warning about tire sizes.
Ugh. People are dumb
