New Front Tyres....now a bust rear Diff?

....... that's a matter that is still being debated!

I was a tyrefitter/Manager of a mutlinational Tyre outlet for 6 years,and worked for different tyre companies in Aust and NZ, I had many a debate with our technicians about placement of new tyres.

Theory 1/ FRONT as thats where 75% of braking and 100% steering is done on all vehicles, but particularly on front wheel drive vehicles, this has been the norm for many many years and is standard practise in the industry.

Theory 2/ REAR as this has better traction/grip for rear wheel drive vehicles, no as much a common practise, but does occur.

Theory 3/ ALL 4 CORNERS as this has dual benefits, better steering, braking and grip (no matter what vehicle). Mostly used on 4x4 and all wheel drive vehicles, no so common as cost is a factor to the customer, good owners will forgo the cost and replace all 4 tyres, others will opt for one of the above options.

As a footnote: Manufacture/Industry manuals stipulate rotation of tyres from the front to the rear ie: new tyres on the front, has been ever since I was a fitter (going back 20 yrs now!)

Commonsense (pffffffffft) and a few questions can avoid serious trye wear and drivetrain damage, never assume the owner is an idiot (even tho it maybe the case) as they drive the vehicle everyday. Listen to their 'thinking' and be tactful with your reasoning, if in doubt send them elsewhere should you be unhappy with their requests.

Worst customers were the ones bringing in their own tyres (usually 2nd hand) with sidewall cuts, bald/lifting tread etc etc to put on a car with a Baby seat in it!! We NEVER fitted them! - explaining the dangers usually fell on deaf ears!

Finally got the Freelander into the garage to replace the diff - that done and the whine from the rear is still there??? Next, both rear bearings are replaced and no prizes for guessing.....the noise is still there??

Anyone got any suggestions to help the garage out - it seems that they are replacing random parts with no noticible difference and meanwhile the bill is now hitting 1400 euros and they have still not fixed the cause of why I took it to them in the first place.

Think the main theory behind equipping the rear wheels with new tyres is that people tend to drive within the limits of their front tyres (cornering/braking) therefore if you fit the best tyres on the rear, you will always be driving within the abilities of the rear tyres, because the front tyres will be worse.

Could the particular make of tyre be the problem - noisy Tyres - what pressures.
