35s and 36s.

How stupid would it be to put 35" Gumbo Mudders in the front.
And 36" TSL SX Swampers in the rear?

 

[Rangersrule91]

Doesnt sound stupid...

 

[james99]

dumb if you have 4 wheel drive. u will break your t case

 

[Sunk]

Figure out what the tires actually measure, they could be close enough that it'd be fine.

If you air the 36s down a bit in relation to the 35s you'll be fine...the tires will be almost the same diameter.

I ran 32s rear and 33s front for awhile with no problems. And they were at the same pressure.

 

[fordtrucknut77]

yea as long as you never ever put it in 4wheel drive on a hard surface an inch difference in tire size wont damage anything its no different than running a 3.50 gear in the rear an a 3.54 gear in the front which lottssss of fords came factory with

 

[wahlstrom1]

Yup, and actual tire dimensions vary a LOT from advertised size. My 35" Krawlers are taller then a set of 37" boggers, and my 33" BFG AT's were only 31.75" tall when measured.

Adjust the tire pressure so that they are within .25" in height and you should be fine.

i run 3.73's rear and 3.55's front at the moment, thats more than a difference of an inch in tire diameter. dont put it in 4wd on the road and you'll be fine.
