Happy New year all.... Just wondering if anyone can offer a pointer or confirm my suspicions on a strange steering effect on the old beast.
A couple of months back I had a pair of new tyres in the form of
235/70x16 Insa Turbo Traction Track Extreme All Terrain Initially (as I was trying to prove the diff that was fitted 15 months prevuious was now w4nked) I had 'em mounted on the front to prevent the garage blaming chunky tyres for rear axle noise.I then got them re-fitted to the back so better braking efficiency with the older less chunky AT's and fairly shortly after noticed the steering a bit "lively" worst problem being in the nearside lane of the poorly maintained M5 where you can see significant trenches from lorry wear. I appreciate these grooves would give a problem to most cars but the Disco becomes a bit of a handfull as it jumps from track to track.
Front wheels are fairly low on tread Cooper A/T style so diameter of new must put the rear axle a good 3/4 inch higher then the front.
Does the group think this would change the castor angle geometry of the front end enough to create such a marked difference in handling or could it be something more evil like squidgy rubbers or dodgy dampers?
The beast has around 185,000 miles and due to business comitments , garage serviced and maintained so generally kept up together pretty well.
Cheers Pete
