Disco 2 265/70r16 on standard height DII?

As the question states on the title, after measuring the diameters I see it may rub on the front bumper - but I plan on removing that in the future, anyway.

Have anyone else this size on theirs?

I should also add my current tyre size is 255/65r16!

Thanks!

Not again!
Yawn.

I have used this - what are you implying, they do or don't fit? I only recently bought my disco and I'm a little inexperienced, so pardon my unknowingness

Before you spend on such big tyres read this 255/65 or 255/70 Pros and Cons? and if your's is auto it's even worst as the VSS(vehicle speed signal) is important part of the engine and autobox management too... all you gain is ground clearance and ''macho'' look while everything else is messed up...including consumption, unless you want to spend big money on proper tuning too for such tyres

Don't take it the wrong way, it's just that this question has cropped up a lot in the past couple of weeks and I have posted this link before at least twice. If you get your tape measure out and measure from the centre of the hub on full lock in each direction, as well as with the wheels straight, it'll give you an idea of what size tyre will fit in relation to surrounding parts of the vehicle, but do remember that will only be true when the vehicle is running straight and level. When the wheel rises in the wheel arch i.e. going over a bump, the nearness of surrounding objects will change, i.e. the tyre will get closer to them. So measure the distance from the axle to the bump stop then take that away from the distance from the top of the hub to the wheel arch, for example, and that will give you at least a vague idea of where your tyre could end up in an off-road situation. Once you know roughly that point above the hub, then you can relook at the measurements you first did. i.e place the tape on the tyre or whatever at the height above the hub that you got from the axle to bumpstop calculation, then measure forward and back as if the centre of the tyre was there, doing lock to lock again. And yes, I am aware that this doesn't take into account the thickness of the tyre, but it should still give a broad outline so you can see what would definitely fit, what definitely wouldn't fit and what would be in the grey area in the middle.
Others will jump on with what they have and have tried and what was ok and what was not.
Incidentally what are you aiming to do with the truck?

I have measured from the wheel hub already to the arches, and they fit, but with only perhaps about an inch or two of space to spare. Again, I wasn't sure about articulation but I'll try see how that is with what you said.. It's just the front bumper I'm really worried about, but that'll be replaced soon with an aftermarket bumper with more clearance.

As for what I'm doing with the truck - overlanding, so a lot of rugged trails that'll need good tyres for the job. I've been trying to decide on tyres sizes for weeks now, it's killing me! Lol

Well done @sierrafery! Scared me sh1tless and I wasn't even thinking of changing my tyre size. They really ought to put this in the handbook don't you think? Something like "Change your tyre size at your peril!"

In a nutshell: The main fator in this tyre size thing is the VSS, as the whole management of all the systems(engine, transmission, ABS, ACE, etc) was ''calibrated" from factory to a VSS calculated for standard dimension tyres, increasing the dimensions without a remap to suit the new VSS is mixing up the whole algorythm

ENGINE MANAGEMENT SYSTEM - Td5, DESCRIPTION AND OPERATION 18-1-39
Vehicle Speed Signal (VSS)
The VSS is an integral part of the ECM’s overall adaptive strategy. The ECM receives the signal direct from the
SLABS ECU. The SLABS ECU is not connected to the controller area network (CAN) so therefore is hard wired.
Vehicles fitted with automatic transmission have two vehicle speed input signals to the ECM. One signal is from the
SLABS ECU and the other is from the automatic transmission ECU. The ECU compares these speed signals.
The ECM also receives transfer gearbox information. This allows the ECM to take in to account the vehicle being
driven using low range gearing and compensate as necessary. The signals generated by the SLABS ECU for manual
transmission, and by the EAT ECU for automatic transmission are received by the ECM in the form of a PWM signal.
The frequency of this signal changes in accordance with road speed.
The input signal for the SLABS is measured via pin 13 of connector C0658 of the ECM. The SLABS ECU generates
a PWM signal switching between 0 and 12 volts at a frequency of 8000 pulses per mile.
For vehicles with automatic transmission the input signal for the EAT ECU is measured via pins 32 and 35 of
connector C0158 of the ECM. These pin numbers provide a bi-directional communications link using the CAN data
bus.
In the case of a VSS failure on vehicles with automatic transmissions the ECM applies default values derived from
the EAT ECU. There is no default value for manual transmission vehicle.

I have a manual disco, just to add!

Another thing about overlanding. If you have tyres on the truck that are not a fairly standard size in the countries you'll be travelling through, bear in mind that getting replacements, if you shred your stock through, will take a long time. The more standard they are the easier it will be to get replacements. Not that I am hoping you get loads of punctures or anything! How many spares are you thinking of carrying and what sort of surfaces are you expecting to be driving over?

Good, one problem slightly but only ever so slightly lessened then!
Do pay careful attention to what @sierrafery says. He really does know his sh1t.

Also, nothing too extreme as I live in the UK, but I've been planning to go around europe, scandinavia etc.

In those countries you may be lucky with weird and wonderful tyre sizes, I dunno, but in Africa....?
Try doing some research as to what surfaces are hardest on tyres, overlanding sites and places like AULRO know this stuff better than the average Brit also the "wheeling" guys in the States.
In the UK mud tyres tend to be what get talked about a lot, last edition of LRM they were going on about the 10 best tyres for your truck and they were ALL bashing on about Mud tyres versus All-terrains. No one mentioned crawling over rocks!
Sidewall damage is the sh1tter. And more likely in rock strewn gullies. You can mend a puncture on the treaded part of a tyre, nowhere else.
Northern and Eastern Europe, you'll be more concerned about Winter tyres and Mud tyres. Some allegedly do both!
You'll notice we've moved away from size to construction and planned use. Also are you thinking of fitting a winch, for self-recovery if nothing else?
This thread may need to go elsewhere!!!

With such tyres you'll spend at least 10% more on fuel... the VSS is affecting the manuals the same way when it comes to the engine management and ABS, just that on autos is even worst cos the autobox management is involved too... and i didnt even mention the extra stress of the drive train and steering

I was planning on AT BF Goodrich 265/70r16 - in the future, a front bumper and perhaps a 2 inch lift. But if these cause a LOT of problems like the guys are saying, I may not..! I hardly use this vehicle as I have a van for work, so there's not much mileage used on it besides the occassional trip to somewhere like Cornwall or Scotland.

So why would you fit such expensive and heavy tyres then? ... i know they look good but beside that they'll cause you only trouble, the ride will not bee too pleasant cos the vehicle will seem powerless especially uphill or on take-off

Not gonna lie, looks are a factor - but I do look for better performance when tackling tracks, mud etc. Would you suggest having the same size, but just in all-terrain? Or perhaps something like 255/70's for that extra height under the diff? Clearance has always been key the way I've thought.

That write up was absolute rubbish. Nothing actually useful was written in it.

Cheers

Good tyre if you do mostly road driving with the occasional off road venture. I have Goodrich ATs and they are fine, also have General Grabbers and they are great too.
Are you going to travel on your own or with some sort of club/group?
I would stongly advise you get involved with some sort of off-road training if you haven't already done so and also some winch training. Before I knew better I headed off with just the wife down some seriously dodgy green lanes in the winter snow in the Yorkshire Dales. After just one day's offroad driver training. Thank God this was just enough to keep me out of serious difficulty, but knowing what i do now it makes me realise how lucky I was not to get totally stuck. No winch, no recovery gear, no survival gear. Would never do it again! And that was in a manual 300tdi with not very special tyres.
Have fun safely.
