Wouldn't the coils bind before the shocks bottom out?

No. If you have more distance between your bump stop and where it meets the axle vs the length of your shock piston your shock will fully compress before your bump stop can stop your axle from articulating causing damage to your shock.

so with the RC 2.5" lift and 2.2 shocks do you need extended bump stops running 31s??

its all going to depend on the compressed shock length...you need to find that out for front and rear. my suspicion is rears definitely will require at least 1-1.5" and the fronts may require 0-1.5"...again it depends on the compressed shock length.

in front, 13.5" compressed length shocks will fit into the stock location, without bumpstop extensions, with 31s. 14.5" requires 1" extensions, 15.5" requires 2" extensions, and so forth. In the rear 12" compressed length won't require any bumpstop extension...13.25" would require 1.25" bumpstop, 14.5" would require 2.5" bumpstop...and so forth.

If you have the Jeep in your picture, you can run them without a lift with the right back spacing, but they look sweet with a small lift.

I have a 1998 TJ with 2.5" Rancho lift and 32's... works great. Perhaps a little sluggish getting up and going in comparison to stock, but no issues at all.

Don't forget guys that the bigger the tire, the more strain on the weak D35 rear axle. I'm putting 33's on mine but am always going to have to think about how I use the throttle in fear of breaking down on the trail.

I have a 2" BDS spring/shock lift and a 1/2" Rokmen body lift (to fit their gastank skid) and I like my Wal-Mart Goodyear Authority 235/85R-16 tires that measure out to 32". Works for me.

Welcome to the forum.

You should add a 1" body lift. 2.5 isn't adequate for 33 alone. 32"s will work fine though.

Obviously there is a difference..... but ive got to ask. Im about to buy tires and rims. Is there a difference between going from a 15 inch rim to 16.... vs going from a 31 to a 32 inch tire?

Yes there are more options for a 15" wheel as far as tires go. Plus the cost of say a 33" tire for a 15" wheel will be much cheaper than a 16" wheel.

Only buy the 16" if you anticipate doing rotors / big brake kit that won't fit inside a 15" rim. At that point you'd then be asking about the tire choices in 17".

You can run a little larger tire with a spring lift if it's a four cylinder. Since the front weighs less a 2.5 spring can give a little more lift than that in front. when I flex as much as possible, the springs start to raise the frame and body too. I have extended bump stops, but can't fully compress my 2.5 springs due to the lighter weight.

Splitting hairs. What about a winch, after market bumper or other armor? What about the rear end which wouldn't be affected by the 4 vs 6?

An appropriate lift will consider all the above, select the right spring weight, and you still end at a 2.5 inch lift that us inadequate for anything over 32's unless othet mods like a body lift or fenderectumy.

Of course armor and a winch affects weight/height. I didn't say it wouldn't. Add a winch to a 4 cylinder and to a six cylinder. The four cylinder is still a couple of hundred pounds lighter. Literature from spring companies sometimes even mention a height difference if it's a 4 or 6 as well as hard top or soft top in the rear. If a manufacturer mentions it, i don't call it splitting hairs.
