And those are some badass tires! I'm jealous! Wish I had the extra $1300 laying around for a set!

 

Your 2500 has absolutely nothing different than out 1500's (motor and tranny wise). Trust me, install them an you will understand.

 

And an inch or two does make a big difference. I just went from a 33" tire to a 34.5" tire (measuring when installed on the wheels, not just reading the sidewall) and it is totally noticeable. I have 3.92 gears with 35" tires and it sucks.

 

That why when ppl ask for gear size, We say 4.10 = 33 and 4.56 = 35 4.88 =37.

 

im running km2's up front and the old style m/t in the back. i personally like the old style better but when i bought my new fronts the guys at the shop f'd up my order so they gave me a good deal that i couldnt afford to pass up

 

nice tires.

I have a set of km2's also and I like them I haven't had a chance to give them a good test yet but, I had them in the snow and they did pretty good.

 

im excited to get them on, im sure im going to really like them. As soon as i get them on ill post some pics up.
