tire/wheel size

ok ok so i looked at a bounch of pics and i cant do the low thing but the idea of 22.5s or 24.5 is just f'in wild to me so where can i go to find out what size tire is how tall? i think i can make room for something 35 or 36 inch tall. one more thing on the make my truck a big wheel plan do i use a steel inside wheel on the rear? hope < that ? dont get me tard of the year.

has ALL kinds of calculators... metric tire size, gear ratios, etc etc

If your going with ".5's" you can run a steel inner, or outers, or fronts.

If you want run a 22.5 or a 24.5 and stay in the 36" range then a 22.5 wheels is your only option. With a 255/70/22.5 tire you are looking at 36.6" tall and on most trucks you will need a leveling kit or small lift kit. You can run a steel inner with these or all aluminum.

With the 22 or 24 wheel option you will have to step up to an all terrain or mud tire tread to achieve that height. The normal 305/40/22 or 305/45/22 height is 31.6" and 32.8" respectively. A 305/35/24 is 32.4" tall. With these you will need to run all aluminum wheels as to you cannot mill a steel 22.5 or 24.5.

well this is still early in the planing stage. i been collecting parts for about 2 years to build a heavy 4 door. this is the reason i dont want the milled down wheels 22 or 24 and light tires. i need something to pack a load and the 16 inch rubber dont last. the plan is to use a C60 frame with a 4 door cab and a C70 tilt nose and a dually bed. i was going to run a dana 60 up front with a dana 80 out back but that may change now that in going to put a cat in it and not a cummins i know that the front tires 16inch on my old dodge didnt hold up for long and i need something thats going to last holdng up a 3308.

Then any of the commercial grade tires will be the right ones for you in 22.5 or 24.5. Most all of them are 16ply and will last upwards of 200k on a normal 1ton truck.

thanks for all the help on that. if i read right you make the adapters for the 8 to 10 but noone makes them for a ford superduty 10 lug?

That is correct. The bolt circle on the Ford 10lug is too big for the hub bore on the 10 lug semi wheels.
