Piston Slap: Spare Me Your AWD Drama

TTAC Reader DeSoto writes:

Greetings, Sajeev — longtime reader, first time writer, and I enjoy the content your column adds to TTAC! (Woot! — SM)

I recently acquired an all-wheel drive 2014 Cadillac CTS with about 15,000 miles on its factory 255/35 R19 Pirelli P7 run-flat tires. Looking ahead to an upcoming 3,500 mile driving trip, I have concern for the durability/drivability of the run-flats. The CTS is not equipped with any wheel-changing tools (jack, wrench, spare tire/wheel). A spare tire assembly (for the CT6) is available online, but I believe the standard compact spare is too small in diameter to be compatible with the 19-inch wheels on the AWD drivetrain. I prefer the freedom of having the option of changing a tire myself and continuing on my way, rather than waiting hours for assistance. I am thus considering, in order of my current preference:

Theflyersfan Expect a press report about an expansion of VW's Mexican plant any day now. I'm all for worker's rights to get the best (and fair) wages and benefits possible, but didn't VW, and for that matter many of the Asian and European carmaker plants in the south, already have as good of, if not better wages already? This can drive a wedge in those plants and this might be a case of be careful what you wish for.
Jkross22 When I think about products that I buy that are of the highest quality or are of great value, I have no idea if they are made as a whole or in parts by unionized employees. As a customer, that's really all I care about. When I think about services I receive from unionized and non-unionized employees, it varies from C- to F levels of service. Will unionizing make the cars better or worse?
Namesakeone I think it's the age old conundrum: Every company (or industry) wants every other one to pay its workers well; well-paid workers make great customers. But nobody wants to pay their own workers well; that would eat into profits. So instead of what Henry Ford (the first) did over a century ago, we will have a lot of companies copying Nike in the 1980s: third-world employees (with a few highly-paid celebrity athlete endorsers) selling overpriced products to upper-middle-class Americans (with a few urban street youths willing to literally kill for that product), until there are no more upper-middle-class Americans left.
ToolGuy I was challenged by Tim's incisive opinion, but thankfully Jeff's multiple vanilla truisms have set me straight. Or something. 😉
ChristianWimmer The body kit modifications ruined it for me.
