The real reason they recommend putting the new ones on the back for FWD is because the rears wear pretty slowly and can be a fair old age, this means you keep the tyre age down.

but the general 'advise' from the tyre companies & subsequently Costco, is new to the rear irrespective of FWD or RWD. Costco will only sell you 4 new tyres if 4 wheel drive (not sure what they'd say if it was only slip & grip/part time 4x4  )

RWD is less of an issue as they wear at a similar rate to fronts (or faster on the rear if trying hard).

By applying the always rear rule its simple for the knuckle dragging tyre fitter and they can apply it to all

The 4WD is because to many cars now are AWD rather than 4WD so have a clutch based Haldex setup which burns out when the tyre diameters are excessively different (plenty of 'sporty' VAG models about with AWD warning lights on as a result). Again on something with a transfer box its not such an issue.

pretty much what MB said to me when I questioned Costco only wanting to sell me 4 on my R Class

Ford recommended swapping all four at once on the 4x4 Sierra and Granada. They had a chain driven transfer case similar to the Merc set up

When I emailed MB, their was reply was that it was OK to replace just 2 as long as there wasn't too much difference in tread depth .... make of that what you want. At the time I wasn't prepared to spend that much on 4 tyres

I reckon the rears on the Mexican will be Donald-ducked well before the front tyres.

I'm told  power and torque only goes to the front when there is a lack of traction at the rear.

That's roughly how it feels to drive....RWD.

Yes but that is because its probably an AWD and not a 4WD, so may well need all four changing at once
