It's option 1) all of the way.

A) Virtually no summer tire made today is anything but a sport or 'racing' tire. Pretty much everything is all-season. And if it's not it's winter or sport.

B) Even the best no-contact mounting machines risk at least some wear on your brand-new wheels.

C) Factory balanced tires are the best balance you'll ever have. Only a Hunter GSP9700, operated by someone who truly knows how, will come close. All others won't.

D) The tires your car leaves the factory with carry a TPC Spec number. According to your owner's manual, replacement tires should carry that same TPC Spec number.

E) You're adding a lot of cost, to no known benefit: but to a known series of risks.

Part of what makes all the Gen 2 Cruzes "eco" Cruzes are the tires: Low rolling resistance. With Gen 1, they were only on the Eco model, now they are on all models.
You can swap them out and get something with a little more grip and perhaps wider (215 mm instead of 205), but that might shave off a few MPG's.

LRR tires also factory on gen 1 diesels.
