Where would you put the new tyre

[Ean Austral]

Gday All,


I have 5 tyres, 4 are 80% tread, 1 is 100%, prefer not to leave the spare at 100% so where would you put the one with 100%.


I normally rotate my tyres so this doesn't happen but these are rims and tyres I purchased 2nd hand. Am thinking either rear but just thought I would post the question to others.


Cheers Ean

Too late mate.... Its not going to be part of this round... It will cause problems with the TR/DSC

Is it that sensitive ? wouldn't have thought it would make that much of an issue.


So what happens if you get a flat and have to put it on when they have worn another 20-30%

The rolling diameter of a radial tyre is almost completely independent of the tread depth, it is a function of the length of the steel belt layer. If the system were that sensitive it would freak out every time you turned a corner. I wouldn't worry about it, back left is as good as any place.

Could you buy a 6th tyre at 100% and rotate the 2 100% tyres in on the same axle.
So for instance have the 2 new ones on the front, and 2 @ 80% on the back and 2 @ 80% as spares.

It's basically what I'm doing with 6 tyres and rotating every 10000km.
And no problems with TR OR DSC.

5 wheel rotation normally introduces the new tyre at the back right:

Corners don't upset the system because it uses steering angle input in its algorithms.

And yes, I've known them to get upset... Even slightly off and you can feel the vehicle "correcting" for it..

It's not a huge difference required to begin to make the machine start to compensate.

You could give it a go... In which case, RHR

Front is the best with AWD vehicles Ean, that's what I was told and what I've been doing as well, on the D2 and now the D4, but I guess rear should be fine also, according to Bridgestone.

The reasoning behind going to the front, had something to do with less drive from the front diff with the 60/40 split, I think you would only worry if the DSC was going off on a regular basis after fitting the newer tyre.

Ahh well just as I expected , back left, back right, front , and leave it as spare, or buy another tyre.


eani, meanie, miney , close my eyes and see where it goes.


Thanks all for the replies.

Speak to Basil135

He recently asked for the spare to go into rotation and the service manager was adamant its was too late...
