I had 4 of these fitted in January http://www.eventtyres.com/en/content/ml698  225/70R16 102H @ £66.66 each.

They got me through the worst of the bad weather (6ft Drifts) over the moors last year.

Hey that doesn't look bad.  got 4 x WK 245/65/17 coming up soon.  Completely undecided but not the goodyear wrangler crap thats on there now.

[bluevanman]

it took me 4 tyres 4 tie rods and a recon steering box plus laser tracking to cure the wandering all I got to cure now is the wobbling

[paulbaron]

further to the steering gremlins and the tyre wear issues, my n/s/f is evenly worn but more worn than the other three and this is not the only grand i have seen this on. anyone have an opinion about this

[bluevanman]

diffs always have a tendency to drive 1side mebbe that and a different compound tyre?

Too many roundabouts where you live

Thanks for the info. looks like i will have to change the tyres on the rear, and put the good one on the spare.

i know the quadra drive is permanent 4wd but i though the front wheels were only driven if the rears lose grip? ie it normally only drives the rear wheels?

Wrong.  Catch is in the word Permanent.  You have to have 4 identical tyres (with the right prewssures .... thinghy ).

See it this way : if your rear tyres are bigger than your fronts, or the other way round, they will be fighting each other through the transmission & transfer case resulting in excessive wear and ......BANG .... down the road.

tech advice that is sensible from Dutch

You have changed bro

Just swapped the spare so that now i have the same make of tyre and tread wear on the rear, then carefully matched all the tyre pressures, and  it had made a dramatic difference. hardly any wondering, and it doesn't feel like its going to rollover in the corners.

reading up on the quadradrive system it calls it an "on demand 4 wheel drive system" it normally just powers the rear wheels 

[Dutch]

I doubt that   

Maybe more power is directed elsewhere in some way in ice conditions but the truck IS permanent 4WD.

That's why it is also inadvisable to tow on its own wheels because without lubrication to the box & transfer case ..... well you can fill in the rest

Makes a big difference

Yup, the one thing I did not have on ye ol' WJ was steering issues. Twas always bang on.

roundabouts are not a big problem its the fecking traffic lights that do my swede in.

It's biased to the rear normally but only around 55:45

up date from wiki:
A notable feature available in this generation was the automatic four wheel drive option called Quadra-Drive, which employed the New Venture Gear NV247 transfer case. This two-speed chain-driven transfer case uses a gerotor, a clutch pack coupled to a hydraulic pump, to transfer torque between the front and rear axles. The transfer case contains three modes, 4-All Time, Neutral, and 4-Lo. In 4-All Time, 100% of torque is sent to the rear axle in normal conditions. If the rear axle starts spinning at a higher rate than the front axle, hydraulic pressure builds up in the gerotor and causes the clutch pack to progressively transfer torque to the front axle until both axles return to the same speed. Neutral mode is intended for towing the vehicle. In 4-Lo, the front and rear axles are locked together through a 2.72 reduction gear ratio. The NV247 transfer case is mated to front and rear axles containing Jeep's Vari-Lok differentials. Vari-Lok differentials also use a gerotor to transfer torque between the wheels on either side of the axle. The major advantage of Quadra-Drive was that the combined transfer case and progressive locking differentials in each axle could automatically control traction between all four wheels. However, only the center differential could be permanently locked, and only in 4Lo. The Quadra-Trac II system included the NV247 transfer case with the standard open front and rear differentials.
