Well picked these up today off my buddy off his massivly lifted older cummins ram.. hes leavin the province for a while and needed snow tires so he sold me these for dirt cheap, just gotta lift the truck a little more to fit them i think.. right now i got a body lift and prekey'd with shackles. I know they would fit fine in the back but the front looks a little sketchy tryin to stuff em. Also worried about gearing. Called the shop today to price out gears but i have no idea if i should go for 4.56's or 4.88's. Im doing about 90% highway right now, but when summer comes ill be doing more wheeling. Also worried if 4.88's will even fit in my diff's, ive heard multiple people say they wont, but have also heard many people say they do. I have a 2008 FX4 with 4.10's currently. any help would be awesome!!

 

Those are just the KM, not the Km2 right?

i have those, and to be honest, they pretty much suck in snow, i slide all around in them its pretty bad. ha

 

Yeah just the regular KMs, i had the KM2s and loved em, but yea im only planning on running these in the spring and summer, and only temporary till i buy brand new 35's

 

yeah, mine are pretty noisy, but they will work great for the mud and dirt, i'm not sure what i'ma get when these wear out, probably the km2's

 

you should be ok with 4.65's and as you said, i don't think 4.88's will work.

 

Two things.

1. Those tires will fit fine with your current setup. Check Ty's 4x4. He's running the same size I believe on the same setup pretty much

2. 4.88's will fit fine in your diffs. It's 5.13's you have to worry about.

 

Nice tires! As far as I know the only reason that the 4.88s WONT fit is if you have the Torsen rear diff.

 

Correct.

 

if you where on 31 stock go with the 4.88 for the 35, the final ratio come really close the 4.10 with 31. My speedo is offset be 5 kph at 120kph, dont have to but a module to change the speedo rating that way

 

so for him to use 4.88s he'd have to remove the torsen LS or just use 4.56s?

 

correct

 

cant wait to see the truck with them, gunna be killa

 

yea pretty sure i got a torsen LS but ill have to check
