Question Tire and lift questions

Hi guys,

I am thinking of buying a bigger tire 265/70-R17 and I read from others that they donít rub. That is great.

1.
The thing is that I cant decide between BFG KM3 vs KO2.

From what I researched KM3 is just a bit noisier on highway - does anyone have experience with both of these tires and can confirm this?

I usually drive around at 125kmh and all the guys posting videos are driving below 100kmh which is not a good reference point.

I donít mind the higher consumption. I drive 80% on tarmac and we have a lot of forest roads in my country so avoiding mud is a no go, and mostly made from dirth and pulling trees out of the woods (no hard clay like mud).

Also I donít plan to attach the tire to the rime when lowering tire pressure, if needed.

All of my offroading is alone, with manual self-recovery tools.


2.
I also got a suggestion to make a 5cm (2") body lift and I canít get my head around it. Isnít that just lifting the body and I donít gain any ground clearance as the chassis will remain on the same height? I am supposed to buy official Navara lift for the front and something for the rear.


Thanks for the advice.

No experience on those particular tyres, but the body lift is mainly intended for articulating larger tyres within the wheel well. So at 265/70/17, I highly doubt you will experience any rubbing, so a body lift will only do one thing in your particular case - raise your centre of gravity.

Na, don't do that yourself, best take it to the garage.

265/70 has been reported as a size that wonít rub, but of course your experience may vary. Note that not all 265 tyres are approved for installation on the standard 7Ē rim.

For the use you describe, the KO2 will suit you better 95% of the time... but itís that 5% you need to worry about. The KO2 is not as good a mud tyre as the original original KO as the shoulder blocks are closed on every second pair, which inhibits self-cleaning. The KM3 is a substantially better road tyre than the KM2 was and is still pretty good in mud, so of those two given your stated use, Iíd suggest the KM3.

However, the main disadvantage of MT tyres is that they are nowhere near as good at wet road traction as HT or AT tyres. Stopping distances, cornering, wet roundabouts... even on ATs I can have the stability control singing the song of its people in winter days.

A compromise you might care to consider is a square block AT, along the lines of the Kumho MT51, **** Cepek Baja ATZ, or Wrangler Duratrac. These sit somewhere between the KO2 and KM3.

Finally, your assessment of body lift is correct. Your diff will always be the lowest point of the car and only big tyres and/or portal axles will ever fix that. Body lift is to allow those bigger tyres to fit (and give your suspension more flex). Not really suitable for a Navara IMHO but people do it. Thereís a couple of threads running elsewhere about it.

Hi, Agree with all above.

As to tyres I run the KO2 on my nav because I do many kms and have never had a tyre fail. I get 50-60km per set on average. The KO2 does handle a little better on road then the Mud tyre but when in mud there is no competition. The KM3 will always be a better off-road tyre in general. The KO2 is also silent on road which is good if your doing long distance as the Mud tyre does make a droning sound which can annoy you. and a mud tyre also will not last as long when on road. More around 40-50km per set.
I run 285/75/16 on a standard 16x7 rim. Running 15PSI when in sand and mud and 20-22PSI when in rocks and bush the tyres perform well. Both will work the question is do you want: Some highway noise and less traction on wet roads but will work GREAT offroad or no highway noise and just good traction offroad.

As to Lift I would always start with suspension lift. Body lift is really only for running Huge tyres. I have standard 2" lift on my Nav and it works great. All the factory suspension geometry will keep working as intended to help with handling.

Why own it if you don't drive it. #navlife

OK thank you all!

@Jackmck :

With regards to KM3s - I canít imagine the noise levels at 125km: "some highway noise" is this noise really loud so that you canít even talk to eachother in the cab?

Now, with normal tires, the engine humming at 125 is really nice because passengers can sleep much better while driving

285/75/16 this also doesnít rub or is the 2" body lift needed?
I read that 16" and taller is better than 17" for offroad so maybe KO2s and 16" is all I need then?

When you are running 15 PSI - are you using beadlock ?

BTW: I dont care about the rain and wet tarmac issues... I have winter tires for the winter. We dont get much rain and I drive the jeep much differently then the normal car also because of height.

If you are prepared to buy new wheels, then for off-road use the smaller the wheel and the bigger the tyre, the better. There is a small cost saving in the tyres too. I like the 16Ē wheels on my Navara for that reason.

However, 17Ē is a very, very common off road tyre size and unless youíre swapping wheels anyway itís probably not worth changing them.

265/60/18 will easily clear - it's only 12mm larger in diameter, and 10mm wider than standard. You wouldn't see that difference without measuring it.

Na, don't do that yourself, best take it to the garage.

OK. Seems like KO2s are best option plus avoiding big mud, especially alone with a kid, in the evening (see pics)

I will call my local Nissan provider to see whether they will provide TUV for 265/70/17 and my original rims, and then maybe 285/75/16 is an option and I can put winter 17" on the original rims and forget about the tire changing.

Still waiting for someone to let me know on KM3s and 125kmh noise level, if anyone has them I would appreciate the info, otherwise KO2'ssss
