All I can say is wow.

I made a last minute change from the Revos to the 265/70/17 KO's yesterday and Im sure glad I did. Not only does the car look awesome and I mean awesome, it rides so much better! Riding down roads with lots of bumps/potholes the 4R used to jump around almost to the point of being jarring. The KO's handle the bumps SO much better and the 4R feels much more planted than it used to.

Regarding power loss and braking increases - they are definitely evident. At first the trans didnt know what to do but as I drove around thought the day it certainly noticed the difference and accounted for it.

Noise - this is very subjective. Cruising around 25-45 you can hear a slight and I mean slight rumble. Normal tires make a wissshhhing sound when driving, these make a whoosing sound. This noise increases until about 55 when wind noise completely drowns them out. At about 75-80 which is what I got them to for a couple of mins today they kind of whistle, kind of rumble its hard to explain but by no means over-bearing.

I got 5 tires for 185 a piece mounted and balanced + 70 for alignment as they were toe out. I was surprised when the guy came back and said I needed rotors and pads up front as I would be griding shortly. This surprised me because there was no evidence of weak breaking/squeaking etc. I suppose its because of my driving and because I live on a mountain at school. I got 40k out of them so I cant be too disappointed. Total bill for the day was 1561 which I think was fair and I think I did quite well on the meats.

I will update this thread as time progresses. So far I am more than impressed with the ride and lack of tire noise. I hope they at least meet my expectations in the rain and Im sure they'll flat out slay the snow.

PICS to come soon; however, they dont do them near enough justice.

That is the thing that surprises people...the BFG AT KO is actually pretty quiet! From my experience with different ATs, it is not any noisier than other ATs...and was quieter than the Nitto AT i had.

I was PLEASANTLY surprised. Its not louder just a different tone until about 75 when they are audible. Now I just have to decide if I should trim or not. I dont even know where its rubbing in the front but it is.
 
:bigok: Looks sweet!


My experience with the K/O's and noise has been similar. I am not convinced they are quieter (I'm not saying they're loud either), I am convinced they are more pleasant. I think it's the noise they make is a much lower frequency than others even at highway speeds and that's why they ARE nicer/better. They look so cool too:D

I think that you're right. That makes sense.
 
Sweet man!

I mounted mine with the white letters in. :)

Here's a pic next to a stock 4R and a poser pic from Centrailia.

Eskimo:

I LOVE the looks. I had the same (SE w/ A/T KO) - however, I ditched my KOs about a year ago. I found them wicked-bad in light snow. So be careful... I was rubbing also - especially backing-up and turning at the same time.

Enjoy them!!!

Congrats on a good choice and welcome to the club.
I have 275's and the only rubbing is on the inner flexible rubber engine bay "flap".

I imagine that could be the case; however, I see them being better than my worn Dunlops. I was going sideways last year coming down a hill. (in snow so light the black was still "visible") Im not too concerned as snow driving for me is minimal; however, when we get any accumulation I know they will do great.

Regarding highway, paid a visit to the grandparents tonight and had 100 miles of highway at 80mph. They are COMPLETELY stable and feel no less confident than with the Dunlops. Road noise is officially minimal; however, power loss is more evident especially when approaching any hill where the torque converter would have remained locked it unlocks and even down shifted at some points. This is a combo of the lower revs and larger/heavier tread; however, I can live with it.

The last test for them is rain - I imagine them being better than my worn Dunlops - if they are this is an incredible tire. If anyone has any questions please feel free to ask. The only thing I kind of want now is a 1/1 lift. That would be the perfect stance imo.

Did I say I was ecstatic?
 
Anyone have any comments about me needing rotors and pads at 39k? Is this completely unusual?

I would imagine that at only 39K that is odd to me, for the most part I would imagine around 60-80K to be somewhere around normal. Are you a hard breaker? Toyota told me last week that I had 10 MM left on my brakes (not sure what the OEM thickness is).

Depending on your local laws, you say your minimum thickness of your rotors, as far as being able to "turn" them or having to replace them. When I was in Clovis, NM the law didn't care so I turned some "thin" rotors, well they warped in a year and I replaced them and the pads again to not have the brake pulsing feeling.
 
I agree chayos00 about the rotors, it could go either way in terms of turning or replacing. When I mess with rotors I generally opt to replace when possible. Turning never seems to end well for me. Warping usually shows up within 9-12months of turning (if not sooner).


I'm sure I'll get :flamethrwoer2: for this but: When I DIY my brakes, if there's no gouges/warping present I just slap pads on, bed them in and let it go... The only 'downside(s)' to my method has been very occasional, brief bouts of squeal and arguably slightly shorter pad life (it seems to be less the 5% shorter). I just hate cutting rotors unless it's my only choice.


As far as pad life goes 39k seems a bit short but spirited driving in the NJ area could explain 39k. My guess is you might have changed out a few thousand miles early but not a lot. If you had said "at 44k I needed brakes" I would think "ah, it's NJ and he's sporty driver..." You did ok.:D

:cheers:
