I hope this can become a "sticky".

Keep in mind, if you reduce your factory backspacing...prepare for additional trimming. Also, consider tire choice (A/Ts and M/Ts will require a little more trimming)

3G Dakota with JMR 6" lift
...we know 35s fit...as of now

3G Dakota with SAS and 8"+ of "peace out-ness"
...37s

 

Added the 265/60/18 tire size that came on some of the later 3rd Gens from the factory.

 

Thank you, I also added. DOH!

 

Figured I would throw in, JMR 6" + 3" Body Lift could easily clear 37's, with maybe some minor trimming.

 

Mods, can we make this a sticky? I don't mean to pry, but it may answer a humpteen million questions that 3G members have.

 

I do believe I just made my first official sticky! All hail me! Now! lol

 

you forget RCX 2.5'' leveling kit! (using it since 3 years)

 

i suggest a +1'' offset!

 

I am under the asumption that these tire sizes only apply to 4X4 models?

I just purchased a 2wd '08 Extended Cab. Going to have 2 Goodyear Authority's
from Wally World put on the rear next Friday. 245/75/16's. Allready have 2 really nice used 245/75/16 Cooper Disc. ST tires to put on the front.
Mind you, my truck will be used for 90% driving to work & back and 10% hauling in chopped wood in the winter months.
Would like to run 265/75/16 Duratracs on all 4 corners the next time around.
I just put (2 months ago) a brand new set of 33x10.50x15 BFG AT KO's on my '94 Trooper. Cant say I am all that impressed with the BFG's, in spite of the $960 it cost me for them.

 

4x4 and 4x2 models have the same suspension and clearance.
