Wow - what was so bad about Stelvio? I've seen a few user reviews and they've been pretty happy with it.
Should be done on any car if there is a large tread depth diffeence
It largely depends on 4x4 system and differentials in use. If you have viscous couplings it's important there isnt a big variation in rotational speed across the coupling. Same with ATB differentials and LSDs. Haldex and torque vectoring type differentials likewise don't like large rotational speed difference.I've had a few 4x4's, still got one now, if I had a £ for every time I read that tyres need to be replaced in pairs or even all four at the same time, I'd be loaded. I've disregarded such advice and have never ever had a problem with any 4X4 I've owned.
I can attest to thatTraditional Landy type differentials are generally very tolerant on the other hand.

Generally with most cars I'd change both tyres on an axle at once anyway.
Yes corners do impose greater speed differences but they're only temporary. Different diameter wheels are a long duration thing that allows heat to build up destroying the oils.I'd imagine the speed differential between inner & outer wheels going round a corner is far greater than any difference a couple of mm's of tread would make. I always suspected that 4x4's notorious with these problems, like the Vauxhall Calibra/Cavalier just had a badly designed transmission/4wd system and would eventually fail no matter what tyres it had.

I had a GLA loaner for a couple of months a few years back, found it a capable little car - quite pleasant place to be, haven’t tried the GLC but presumably the same only slightly bigger
Pretty nice with the 9G box, disappointed with the fuel economy as it was only just better than my 3Ltr V6 Petrol - although it is a brick compared to an SLK...Quite fancy one of those, really good looking car and a brilliant engine with a little mapping

The 20" Rim's are "OK" on decent roads as there is still some sidewall and more suspension movement than a regular car - I'd still opt for smaller rims if I had one. I can't think I'd pick one over a regular "E" or "E" estate though.
