Thread: New D697s fitted

I usually rotate every service (10k km on my old camry). When i get new tyres the best of the old ones becomes the spare and i get 4 new. No problems running tyres opposite directions, though this was only on a sedan, not a 2.6t 4wd.

Havent had to rotate the D3s tyres yet, but when i go from hwy to all terrains i will probably get 5 newies or 4 newies and a 2nd hand spare.

Im not very comfortable putting a 3 or 4 year old tyre thats sat underneath the car on with 3 other new tyres - id rather have 4 new ones with a random spare to get me out of trouble, until i can get a new tyre. Then, depending on how old the tyres are, i buy two new tyres for the front. The next best 2 go on the back and the third best is the new spare. I can always keep the other spare in the shed.

Cheers

I have no issues with a 3 yr old tyre going onto the vehicle. I wouldn't fit it once yet hit 5 though

My average is to wear out a set to my level for changing (~5mm tread and they're gone) so a tyre only gets a 24-36 months life on my vehicles so will never be older than 6 when removed.

Do you know what their reasoning is for this. Barbagallos in Perth have told me the same thing. I haven't asked my tyre bloke in Kalgoorlie who has supplied all tyres I have bought for the two Disco's.

Hi BMKal.

I believe that the issue is that reversing the direction of rotation when you swap a tyre from one side to another may cause loss of integrity of the bands in the tyre. In may cause the tread separated from the casing causing tyre failure. I'm not sure whether it's the same issue now but I have been advised over the years that it's preferable not to swap tyres between sides.

I will consult the forum gear cruncher for information

Good on you Andy. I'm not sure how gear grinding qualifications translate to tyre guru, but here goes.
I never change the direction of rotation, for reasons already expressed previously.
In my humble opinion, uneven tyre wear is generally caused by the following, either in combination or singularly.

1: Mechanical issues such as tyre pressure, ball joints, tie rod ends, bushes, buckled wheels or misalignment.

2: Driving style.

3: Tyre design and/or compound.

Point three is the only one over which a vehicle owner has little to no control.
The more aggressive the tread pattern, the more susceptible the tyre will be to noise and scalloping, due to squirming of the tread blocks.
Tyres that look identical outwardly, even coming from the same mould, can differ in compound from batch to batch.
Some tyres are designed with a softer compound (usually high performance types) on the shoulders than the centre, these tyres can be prone to shoulder wear.

With the D4,D2,i have always rotated and changed rotation direction,never had an issue,mainly been BFG.

With the work vans,front to rear never works well as the front left always chews out,so we have always rotated tyres in a way that also changes rotation direction.

In the last few years we have changed to Dunlop silica something type,and have had about six failures out of three sets.Bridgestones or Kumho,and the older model Dunlop,we never ever had issues.
The failures have been similar,large lump in tread area,usually always at around 60000K to 75000K.
We have used the same supplier,and they have sent the tyres back,but there is no comment from manufacturer.They say the pressures we run and the way we rotate is fine.

Maybe they are wrong,rotating the direction they run may be the issue.

This is exactly what happened to my tyres.
