24.5" vs. 22.5"

that's first mistake, getting a price at a truckstop. I save around $40 per tire for 22.5's x 8= $320 savings compared to 24.5's. dang near get the 8th tire for free compared to what 24.5 would cost. mileage is with in 3000 miles or less when wore out to a 24.5 and $10 more for casings for 22.5 to 24.5's. that's another $80. but that is in my neck of the woods. also fet is a little less per tire based on the weight of tire.

 

Oh really? I guess I must've missed that rule cuz I never have and never will. Born and raised in the upper midwest and learned how to drive in the #### a long time ago. If chains are mandatory I don't go there, IE Denver area. Who wants to go to that black hole anyway.

 

11r's typically have higher load ratings than low pro's

11r 22.5's are roughly 4 inches taller than low pro 22's low pro 24's are about the same outside size as a 11r 22. with 11r 24's being roughly 4 inches taller than its low pro counter part. so going from low pro 22's to tall 24's would gain you roughly 4 inch of ground clearance. (8 inch taller tire)

11r's of both sizes have higher load ratings than there low pro counter parts and tall rubber typically rides a little better over bumps (more sidewall to absorb the bumps)

low pro's are typically cheaper than tall rubber. 22's being cheaper than 24's

 

I think it is called rotational mass. It takes more power to spin more weight. That is why economy cars have little tires and wheels.

Now, most of the weight is in the tire on an aluminum wheel, so if you run low profile 24.5s verses 1100 22.5s, the 24.5 as a package would ostensibly weight less, as both are about the same diameter.

The larger the diameter, the less liking the tire will fall into all the little valleys in the road surface.

24.5s have the look....

 

nah, that rotational mass is a conserved energy. you don't waste it.

 

If using severe duty like oil fields or driving to nat gas wells, I would prefer 24.5. It has higher ratio for gear than 22.5. The 22.5 is known for better fuel mileage but less gear ratio. tire sizes can change gear ratios.
