Tyre Replacement
Hello guys,
Need to pick on your brains. I've been looking at past discussions and still wanted a clearer picture.
My apologies if you have to keep repeating the same thing every other week.
I went to the local Norauto (our friendly Halfords here on the continent) to have tyre sensors installed.
They managed to take off a big chunk of one interior tyre wall and rendered it useless.
It looks like they'll replace it with a new one (don't believe it until I see it) as soon as they can order it.
So today I had to come home on my spare tyre, which I found out to have a pretty big "dimple" on its side wall (apart from being almost a F1 slick).
Naturally I'll replace this tyre as well, so here comes my question:
I'll have 3 used Pirelly ATR with about 20,000 km. All 3 were wearing at the same rate, so for the sake of this exercise, we'll call them identical...and almost new (fantastic tyre guys, thanks for the reviews)
Now I'll have 2 brand new ATR......where should I place them?
Front or Real Axle?
My deepest apologies if this is a daft question, but I really have no idea and I'm not in the mood to ask Norauto what THEY think.
I've had lots of help from this forum before, so now it's your turn....
...and thanks in advance!!!
Mauro
ahh, 1 more thing.
I've tried attaching photos of the injured tyre, but couldn't....so I tried uploading them to my gallery, but couldn't.....
....HEEEEEELP!!!!

If it was me i'd put he 2 new ones on one axle, 2 worn on other & third as spare. ISTR the best ones should be on the back.
To confuse you more, I would put the new ones on the front axle as that's where the steering is & also where the weight is transferred to when you brake!
I operate Trucks & on the same principle, we only put new tyres on the front axle, remoulds (Bandvulc etc) & part worn ones everywhere else.Quis custodiet ipsos custodes?

quote from one tyre manufactor most do advise this
Fitting new or least-worn tyres at the rear
If you are only changing two tyres out of four, whether your vehicle has front- or rear-wheel drive, we recommend fitting the newest tyres on the rear axle. This will give you greater safety in the event of unexpected and difficult situations (emergency braking, tight bends, etc..) especially in the wet. The front tyres generally wear quicker than the rear, especially with front-wheel drive (which applies to the majority of vehicles nowadays). Numerous tests have demonstrated that it is easier to control the front axle than the rear.
This is why KLEBER advise you to fit the new or least worn tyres on the rear axle for.

I've no experience with commercial vehicles. With cars however, the tyres with the deeper tread i.e new, should always be placed on the rear. The reason being that understeer is far easier and therefore safer to control than oversteer.
I've witnessed this first hand when a friend was about to sell his Audi A6. The front tyres were borderline illegal, the rears were well worn but legal. As he was selling it he decided to just replace the front tyres on the front axle. Taking a corner fairly aggresively resulted in the Audi doing a full spin and ending up (fortunately) on a wide grass verge.

With a 4x4 and the dsc type systems fitted to D3/4... this shouldn't be so much of an issue but sticking with putting new ones on the rears does have one big advantage above all others...
The rears can often outlast 2 or 3 front sets and the rubber can degrade long before cracks in the sidewalls appear to by doing this your ensuring the rears stay good enough to give you that grip when you most need it
Each onto their own and all though FFRR Owner, very nearly became a D3 owner
Test piloted a new D4 XS SDV6.. Gone and being forgotten i hope!!

But there is no mention of 4 wheel drive!
On some 4 wheel drives i.e. Freelanders 1 and 2 new tyres or tyres of larger diameter must be put on the rear or damage can be done to the centre diff/viscous coupling. But snow chains can only be fitted on the front!!!! Ultimately it all comes down to the manufacturers recommendations.
I would fit them on the rear of a D3.
It can when others can't,
It will when others won't,
It goes where others don't.

Thanks guys,
I'm always impressed with the amount of knowledge and willingness to explain!
Rear it is then. It makes lots of sense on a "normal" vehicle.
