Different tires size, pro's and cons?

My truck also has 24 steers with 22 drives and drop.

I don't know why. No one takes in to consideration the braking effect. Back drums spin faster then the front drums. The trailer also has 24. So when it comes to braking. My drives and drop drums spin faster then all the other axles. Not a big deal in the city.

I've got the only truck with 22 drives.

My speedo says 71. Gps says 74. I'd probably be around 77ish with 24's. I'm guessing.

 

The speed difference between 22.5 and 24.5 is approximately one gear size.
A 3.55 ratio on 22.5 rubber would be like a 3.70 with 24.5 rubber.
A 3.90 ratio on 22.5 would be similar to 4.10's with 24.5 rubber.
Naturally if you switch from 22.5 to 24.5 you go faster, or 24.5 to 22.5 you go slower.

Personally, I like the bigger tires regardless of perceived fuel mileage.
The big tires give a better ride, they roll over curbs easier and have more cushion if you whack a curb, they give you a little more tire life as well as more rubber on the road, (more traction), and more ground clearance, they don't clog up with mud as easily and the don't toss you around on rutted roads as noticeably as the smaller rubber does.

 

What’s the actual tire sizes?

 

The drops are the only lo's

The rest are hi pro

 

Because the owner is cheap and that's what was available from the used tire store?

 

Nothing cheap about buying new rims to fit cheaper tires.

 

My truck was a Werner truck.

I don't think it came with 24 steers or drop axle.

 

Anyone ever see a 'tire yardstick"?

Looked like a yardstick with a fixed end and a sliding part like a big wooden caliper.
We used to measure the tire that we left on the trailer and were supposed to match another within 1/2" or less difference from the other. Helped tire wear in the bias days...

you could see what the difference in diameter is between steer and drives.....
