I totally appreciate the difference between an MT and AT tire. I guess I thought it was size that was being pointed out as a non-upgrade from stock. I prefer a 255 or narrower sticking close to the 32" diameter.
If my rig has a CAI then it's encapseled in some sort of freak factory package that looks just like a standard air filter setup. Definitely not the open K&N concept. But if it isn't going to help, then there isn't any point in worrying about it.
So first priority: airbags and suspension (Bilstein)
Also - I know what rock crawling is and what it takes. That was a joke...
I may have come off as somewhat snarky in my last post to you. If so I apologize; I tend to have a somewhat dry sense of humor, but that doesn't translate well over the internet sometimes.
Here is what I meant:
Unless you are considering doing some serious upgrades to your suspension, I would stick with your stock tire size (265 70 17). You could probably get away with something in 275 or 285 70 17, but generally speaking when you start changing tire size you need to fiddle with the suspension, alignment and even the speedometer (depending on the delta in tire sizes).
255's are a narrower tire, and while there is nothing inherently wrong or bad about that, they generally don't offer the same amounts of grip as a wider tire (except perhaps in deep snow situations). Honestly, unless you are planning aggressive off-road trips into MOAB or very challenging muddy/rocky trails, your stock tire size is more than adequate and there are plenty of good A/T tires available.
As for the CAI and exhaust: I'm sure they offer
some improvement in throttle response and HP. The point that I and many others have made is that the the
amount of additional HP and performance you get really isn't worth the money you spend; your money would be better spent on suspension, tires, skids, tools, recovery gear, gas, ect.
Does that make sense?
