as above depends on the 4wd set up.
Not a good idea in a subaru forester but a wv tiguan with a haldex clutch will be fine.
tell us the car

Its a range rover L322 (2003-2005 model)

If this is a land rover freelander 1, pre or post facelift, DO NOT DO IT

This will irreparably damage the viscous coupling unit it the centre of the drive train, it cannot cope with even small differences in tyre size front to back when driven on the road for any distance.

This is a known issue, loads of info at https://www.landyzone.co.uk

Other land rover models, have a switchable differential so it's not an issue

Freelander 2 has a haldex coupling which is electronically controlled and does not suffer the issue.

Can't comment on other makes though

Hi Angel
is an L322 range rover

Will you also be replacing the spare. If so you need 3 new tyres.

That was another question, the spare is a standard size alloy, 3" smaller than the ones fitted, so surely even using the spare to get out of trouble would be 'disasterous' according to some??

Front wheels don't always turn at the same speed as the rears. Offside wheels don't always turn at the same speed as the nearside. Cars are engineered knowing how vehicles work when cornering etc etc.
Driving it to the tyre fitters is not gonna cause any kind of imminent damage, despite a lot of text book warriers telling you moving it just one meter will reduce its lifespan by 1000000%

How many miles have you done on different sizes so far?

Probably 8 or 9 miles, but now panicking (possibly for no reason)

The L322 has a torsen centre differential in that model, 10 miles isn't going to hurt it.

OP, can you answer my question in post #2. What is the full tyre size of the original tyre and the one you're replacing it with? Are they different widths?

Sorry Neil I thought I'd replied to everyone

The tyres on at present are 285/35xR22, and the new ones are 285/40xR22

Im kinda swaying with the majority here, you make a lot of sense. Also, if it was really that bad and not the done thing, surely you would ALWAYS get a full sized spare with every 4 wheel drive car???
