I'm building a truck that's going to have tractor tires on it. Thinking about running. 18.4x26" (50") or jumping up to 23.1x26" (64"). I know gears play a roll in it, but about how much hp will I need to run them?
the hp needed will depend on the gear a stock motor will trun them if you got the gear...
Ill be running rockwell 2.5 tons. So whatever gears came in them.
what motor u planning? i would say a mild built will be fine unless u wanna play with the BIG BIG BOYS
also this need to be moved to tech
I have some 2.5 ton rocks im putting under my truck right now, they have a 6.72 gear and i plan on running 23.1-26's on my truck too with a motor around 400 horse
I have a mid built 400 in the truck now. I'm thinking about dropping a 460 in it if the 400 doesn't cut it.
23.1x26 is to big of a tire for a 2.5 ton axle you will break it
50" Vs with alot of hp is badass
63" with little hp slow, alot hp is like 1200+ with those big boys
18.4 26 with bbf 385hp @ rear wheel on a chassis dyno 2.5 rocks works good for me so far. i have broke a few rear shafts
are the 18.4 26 closer to 56"or 57" ?
56"
Are you going to run 1 or 2 transfercases? That makes a difference in how much horsepower you will need.
Going to run 2 t-cases.
you wont need a ton of motor with all the gear of 2 tcases!
So running 6.72 gears with 2 t-cases I should be alright with about 400 hp and 18.4 (50") tires?
