Tires

Been watching a lot of this guys videos. One of the reasons I went with the Ford 150
A lot of good advice from a long time mechanic

Shouldn't make a difference as the sensors measure psi not weight.

If you squeeze a balloon, there's the same amount of air but less volume for it to exist in. Doesn't that increase the pressure?

@Terps, damnable contraptions, the lot of them. Maybe it's NY roads and weather, but every gf I've had claims low pressure lights, and maybe one time in 20 is there an actual low pressure situation.

I suppose it's helpful in that you'll always be checking, but spend $5 on a regular ol gauge and toss it in the glove box.

Next thing, you'll be suggesting people check the liquid level in their batteries. lol

I generally walk around my car when I get gas just visually checking the tires.

If I am pulling the camper, I manually check all the tires with a digital gauge. Especially the camper tires and the spare camper tire. They make them real cheap. I've blown 2 tires pulling my camper. The tires are small and get pretty hot due to the high rotation rate due to small size. Every time I have to replace one, they take one look and are not sure they can find my size but eventually they do. No brand choice, just fortunate they have my size at the main warehouse. Its a 2005 Fleetwood Timberlake popup that I tow.

Do you have "bearing buddy's"?

The volume in the balloon is the same, the size of the balloon has changed, just the shape has changed.

More weight on axle means the sidewalls might bulge, but the bead is still on the wheel. Less tall, more wide. Same tire.

If there is any change I doubt it would be enough to even register.

The pressure inside the tire does change with changing weight, but it is barely measurable within the allowed operating weight range of the car.

There are several webpages explaining it.

What are "bearing buddy's"

I believe the sensor is in the hub, not the tire. If you are just replacing the rubber you should be fine.

The sensor is actually part of the valve stem (in cars that don’t use rotational velocity).

The way to check is check the pressure with the tire off the car then on. I've never seen a difference and that is what I am talking about.
