Anyone with Semi knowledge n here?

Hello.

Im looking at a set of 22.5 or 24.5 rims n semi tires for my Rat rod project. I found 8-10 lug adaptors so Im good there.

Wondering wat the heigth of these tires are? Are they mainly one size? If Im gonna do it then I want insane tall. If I cant overwelm my 36 inch tall ones I can get on My 16 inch rims, I might as well not do it. So I want tall!!! Any suggestions? Tnx, HG

you can get all kinds of sizes, 11R22.5 is full size, they go down from there 295, 275, 255, 235,

the 24.5 rim wont have as many choices as the 22.5, you can look on line for the heights on the sizes mentioned. the 11R24.5 will be the tallest that is not too wide.

295/85/22.5 tires are 10 inches wide and 42 inches tall, I ran that size all the way around on the Freightliner.

The biggest thing you will want to do with the tires this big that you do decide to go with is NOT inflate them to the recommended pressure on the sidewall. I ran 105psi with mine but I was using the tire to it's effective weight rating in carrying 80,000+ pounds, you can possibly get away with even running half that as your entire truck will not exceed the weight capacity on just one of those tires.

The legal loading capacity was what I had to run on those tires, and most States have a maximum load of 12,000 on the steering axle, or 6,000 pounds per tire in that position, those tires are no different in construction from the drive tires or trailer tires, but there was a maximum load rating of 34,000 pounds on the drive axles and trailer axles, or 17,000 pounds per axle, or 4,250 pounds per tire, while inflated to 105 psi.

You have said you are intent on just using these tires on the rear axle only, and whether you use 2 or 4 of these tires, you are going to be well under the weight capacity of these tires, the sidewalls are either 10 or 12 ply if I rememebr right, and with just about no weight on them on your truck you are not going to need all that pressure for the tires to live a long happy life.

The semi tires have the same wear depth cutoff to pass inspection if Ohio requires it, 1/16th inch, but you will never find a semi tire that has anything less than a built in 1/8 (2/16) inch wear indicator and some steers have a 3/16th inch indicator, both companies I drove for had tires had steers with the 3/16 indicators, and the one company even had a contract to buy enough tires in a year to have their name and logo on the sidewall, you might even be able to custom order a pair or set with a custom logo put on, and like I have seen and done, sidewall paint pens DO work, and make the tires stand out on a truck if done right.

with the weight of the tires,, and of the rims ,,total over 100 lbs each ,, something comes into play.. sprung and unsprung weight.. an how it affects movement= power- inertia.. i can't remember too much about it,, but it will take too much power to get that weight moving..you might like to look it up...or else have one heck of a granny gear....

If the 445/50-22,5 tire is according to dimension it should be:
445 mm plus 22,5 inches = 17,52 plus 22,5 = 40,02 inches in diameter.

hemi a good guide is google bridgestone tire as they have a guide on the diameter of the tire or go down to the local truck tire place and grab a couple of pamphlets , we use super singles on our rigs at work they are heavy so I hope you have a good braking system ( like 13X3.5 drums , 12 inch discs or larger )
