I have some opinions about cars. Some of this is based on feelings, some based on facts. I'll leave it up to you to decide.
1) Top Tier gasoline is better. AAA did a study on this and it shows that Top Tier gas is better for your car engine. Top Tier gas tends to cost more.
2) Unless your car requires it, there is no need to use premium gasoline. Regular Top Tier gas is good enough for most cars. Premium is more expensive; sometimes a lot more. You can do more for your car by using Top Tier regular then off-brand premium.
3) The best Top Tier gas is Shell. I base this on that Car and Driver used to exclusively use it for their testing. Plus there's a sticker on the gas cap of my car saying it recommends Shell V-Power which is its premium gas. The next best Top Tier gas is Chevron. I have no basis for this other than their claims.
4) Car and Driver is the best car magazine ever. Although the quality of the writing has diminished a bit in recent years, it's still worth reading. The magazine was amazing when Csaba Csere was the Editor-in-Chief.
5) Michelin Tires are the best. Goodyear are the worst. Two of my cars came with Goodyear OEM (original equipment) tires. They lost air quickly and wore out very fast. I got 11,000 miles on a sedan and 5,000 miles on my Corvette. When I replaced them with Michelin tires, I got more miles and they didn't lose air as fast. The Corvette had more grip in the corners, too. There's lots of tire brands I haven't tried, yet. I used to put Continentals on a sedan I owned and they worked fine. I have no opinion on Firestone, Hankook, and lots of other tire brands.
6) German cars are better engineered than American cars. And Audis are better than BMWs. I have no experience with Porsche or Mercedes. Although my wife's VW GTI had some weird engineering.
7) The best place to buy tires and wheels is Tire Rack. They are often cheaper than your local tire shop and they have a vast selection. If you buy wheels and tires combination, they will mount and balance them for free. The only issue I've ever had with Tire Rack is when I wanted to look up the details of wheels I bought from them ten years after, they no longer had the order information.
8) Blizzaks are the best winter/snow tires in my experience. According to Car and Driver, the Nokian Hakkapelitta is the best winter/snow tire but good luck finding them in your size. And, yes, if you live where it snows, put on winter tires.
9) Studded tires are evil. They damage roads and give no better traction in most situations and worse traction in dry or wet conditions.
10) Electric cars aren't quite ready for prime time. They need to develop batteries that aren't affected by cold or hot. And hold more energy. And recharge faster.
11) And of course: more horsepower is better.
