This is my general philosophy for winter tires. I tend to get crucified for it.

What’s your placard tire size and inflation pressure? That’s the first thing you need to calculate the proper inflation pressure for an alternate tire size.

Opinions are like a certain part of mammalian anatomy: everybody has one, and most of them stink. @CapriRacer is bringing facts. They may fly in the face of conventional wisdom, but that only because conventional wisdom isn’t based in facts. You’re not going to find a standard or law...

Mine are not. All you really need out of that formula is that P is proportional to T, since all the other factors are pretty close to constant for a tire that’s close to fully inflated, so that it’s not drastically changing volume with addition of more air. Room temperature of 70°F is 530°R...

If people are being this picky about tire pressure, I have to ask - how do you account for the temperature drop associated with the air expanding as it enters the tire? Chasing fractions of a psi is pointless when you don’t know the exact temperature of the air once it reaches equilibrium in the...

Check out this video. TL,DW: the TrueContact Tour outperforms a budget UHP summer tire in every performance metric except dry braking, and that’s with the Contis being hobbled by being mounted to a PT Cruiser. Good choice, OP.

Years ago, I was in Texas for work when I got up one morning and found that my rental car had a flat. All the rental company’s roadside assistance would do was to change or inflate the tire. I elected to have them inflate it and drove to Discount Tire, figuring that between my employer and the...

For an Escalade? I’d buy them without hesitation.

Give them a minute. If they're anything like the HL422s I had as OE on my CX-9, it won't be long before you'll be white-knuckling it in every light sprinkle of rain.

Some stores have offered alignments for years.

Well that's repulsive...

My dad once gave me a back in my day… story about how anything lower than an 80 aspect ratio was low profile.

You mean a size that will actually fit the car in question?

If you go to Pirelli’s website and look at the fine details of the Scorpion Zero AS Plus 3 and the P Zero AS Plus 3, it becomes readily apparent that they’re the same tire with different branding depending on whether it’s a “car” or “truck” service description. Tire Rack absolutely loved the P...

Or maybe it’s the other nail, on the other side of the split.

Yeah, mine is almost exactly level to ground. There's a piece of what I'm assuming is the front subframe that you have to reach up and over when accessing the filter, but it looks like the space "above" the filter is clear of that member.

I tend to agree, but it always seems like one of those things where I’m supposed to look for the downside. I can never figure out why I shouldn’t run a bigger filter, but periodically, I have to ask, just to see if anyone has come up with a good reason.

Yeah, I wasn’t planning to use the -3600 as a permanent thing. I just wanted to use the filter that I already have.

I’m about to do my first oil change on my CX-90. I just found that I still have a Fram XG3600 that I got for the CX-9 that the -90 replaced. The CX-90 wants a XG3614, but the bigger filter seems like it would have no problem filling in, as long as it fits. Is there any reason not to use the...
