Hello, quick question : Can I put just 2 new tyres in the back, keeping my 2 worn tyres in the front (like 60% worn) ?
Thx! V8 Addict

Yes! It can when others can't,
It will when others won't,
It goes where others don't.

I believe that's the recommended approach anyway as it means the rear has the best wet weather performance and thus less likely to spin the car in the wet. Visiting from rrsport.co.uk

I'm sorry I have not been precise enough in my question :
I'm not worried about Worn tyres in Front and New in the back, I agree, this is the way to install new tyres.
I'm more worried about the different diameter between new Tyres and Worn Tyres (1 or 2mm), which might cause problems to the central differential because of the different rotation speed of front/rear wheels.
Perhaps this is not significant and I'm worried for nothing... V8 Addict

I did think it’s best practice to have matching tyres all round on a 4wd setup, to avoid over working the central diff.
1-2 mm difference would probably be ok, but if fronts are 60% worn surely the delta is nearer 4 mm? 2014 Discovery 4 HSE

I don’t bother to rotate the tyres so the fronts wear a bit faster than the rears.
Therefore, I tend to buy new tyres a pair at a time. Always fit the new pair on the rear, with the ‘old’ rears moved to the front.
So for a few thousand miles I might have a difference of up to 4mm (max) in the tyre tread depths between the two axles. I’ve never experienced any problems as a result.
I do recall the AWD Volvo V70R’s were prone to issues if there was even a small difference in tread depths. 2006 D3 HSE (Original & still the best)-GONE

I've always replaced mine as a set of four. 60% worn sounds like too much of a difference. D4 HSE EU6 (Known as Jeeves)

Not a problem with the D3/D4 as it has an open centre diff most of the time.
On vehicles with viscous coupling centre diffs, running different circumference tyres at each end can lead to premature wear of the coupling. Visiting from rrsport.co.uk

Which is the ideal, but even on a permanent 4X4. you need to do tyre rotation to ensure even wear across all four tyres.
Unless you want to scrap a pair of tyres that still have plenty of life left. 2006 D3 HSE (Original & still the best)-GONE
