245/55R18 has a bunch of good options. If you mount one on an 8.5” wide wheel, it’ll be reasonably stiff in steering rate while still giving you the ride advantage of an extra half inch of sidewall height.
Mazda, nor any other OEM, makes wheels themselves. They buy them from a supplier. Any steel wheel that you’d buy at a dealership will be from whatever source could fill the order at the best price the last time the dealer needed them.
The first one is what a 20” or 21” wheel would look like on your car, and the second is almost as big. Go to Tire Rack and use their wheel visualizer - it only gives side views, but they’re much more representative of actual wheel sizes.
Second, a wider tire is going to be the first thing you...
So are you looking for the largest diameter tire you can fit in the wheel well? Or the tallest sidewall that matches OE rolling diameter on a 16” wheel?
That's why I always keep a top-up quart or jug on hand. I've had one vehicle out of my last seven or so that took an even jug of any volume to fill the crank case.
Has anybody ever seen comparative VOAs between Kirkland and other Warren brands? I've read that Costco goes beyond regular Top Tier standards with their gasoline, and I wonder if KS motor oil would get a better add pack than, say, Meijer oil.
The thing is, if I go snug plus a quarter turn on installation, I can back it off easily with just bare hands. A few thousand miles later, I can usually get it off by wiping it clean and using textured nitrile gloves, but I still have the wrench or slip-joint pliers handy, just in case.
This. Even when I’m removing a filter that I installed and I know had oil on the gasket and wasn’t over-tightened, it still takes more than I can manage, even after cleaning the filter and wearing a grippy rubber glove.
