Will take one and upload when I get home

ok so after a lot of emails insa have sent me a new Dakar but they sent me a 265/70/16 I'm.not sure this will clear my arch liners so my question is if I put it on the rear would it be ok,I would say yes because the front may bind as you turn but the rears are fixed,any input ,it fooked up 18th march,I just recieved it today

Perhaps things have massively improved these days but I remember borrowing my brother's Series II Landy on mud tyres years ago, road conditions were snow and ice - on deep snow they were good (apart from lateral stability) on thin snow and ice they were bloody lethal necessitating a switch to my Imp on remould "country" (modern equivalent would be all-seasons) tyres for my own safety! - the Series on muds in icy conditions on tarmac was deadly, wanting to swap-ends or slide at every opportunity - the tyres were far too hard and gave zero traction, it was only vaguely drivable in 2WD which imbued some sort of directional stability, in 4WD it under-steered like an oil-tanker at anything above a crawling pace. Never had similar issues driving my classic or P38 on various ATs. Unlucky combo of car conditions and tyres? I don't know, but it wasn't what I was expecting from the off-roader of choice. The Imp's traction was sensational! Snow covered Muswell Hill? No probs. Stopping wasn't as clever though until I put a couple of bags of sand in the (front) luggage compartment.

My opinion is you should only use mud tyres where you actually need them, if you're just green-laning then good ATs would be much kinder to the track than muds which will chew it up. Which of course isn't an issue on proper off-road courses.

There a lovely looking red Defender near me - snorkel and all on standard car road tyres - he must have another set of wheels for off-roading - not that I've ever seen the car moved in all the years I've passed it...

If you put the different size tyres on the same axle your diff will have to work hard as the rolling radius will be different and also will be illegal and make all sorts of handling problems.

A front to rear tyre radius mix would make quick work of the VCU - fatally overheating it. Any tyre size mix on a modern car may also fool the ABS into thinking one or more tyres are slipping cutting in the ABS early - leaving you with no brakes - with any luck the system would throw a fault and disable ABS. The post 99 P38s with 4 wheel TC may also try to brake the faster spinning (smaller radius) tyre(s) leading to rapid brake failure.

Mixing the rolling radius of tyres on any car with four wheel drive or ABS - let alone permanent four wheel drive + ABS + active TC is asking for trouble. Subaru don't invalidate your warranty for mixing tyres for nothing.
