Stupid Question
I'm in the need of two new front tyres due to uneven tyre wear.
I would have a wheel alignment carried out upon replacing the fronts to get to the bottom of the uneven wear.
Here's the stupid question..... Is it a necessity I replace all four at the same time? I appreciate it's probably best - but the back two have even wear and plenty of tread left...
Currently on GG AT's and currently thinking of replacing with GG AT3's (both have same speed and load rating I believe).

In an ideal world, you'd want four tyres with the same amount of tread on. In reality, it won't make any difference, the centre differential can cope. Richard

@ LT.......
Why is it good practice to change the rears?
visit a Costco and they will tell you at length ! (and try to see you 4 tyres when it's not necessary ! )
!!! posts keep posting whilst i'm typing !!!
apparently it's safer to have a front tyre blowout than a rear and putting new tyres at rear lessens chances of a rear blowout.

To stop the rear stepping out ISTR.
I tend to have the same type all round (but would mix as long as similar types and same on each "axle") but wouldn't worry too much re tread depth. Many of us will have a new tyre underneath as a spare and 3mm all round, the diffs can cope if that one goes on.
Saying that nice new rubber on all round today.

Better to under steer at the front than lose the back end.Last of the D4 HSE...

From Michelin:
Quote:
Fit the new tyres (or the least worn) on the rear axle of your vehicle, whether it is a front or rear, 2 or 4 wheel drive (unless there is a difference in tyre size between axles.) This ensures better control and handling in situations of emergency braking or on tight bends, particularly on wet surfaces. By fitting the best tyres at the rear, the driver enjoys a substantial gain in safety.
Why fit new tyres to the rear?
We advise fitting new tyres to the rear axle primarily to ensure that vehicle stability is maintained in difficult driving conditions, such as hard braking or cornering. This is especially critical on wet or slippery roads. As most modern vehicles are front wheel drive, the front tyres wear faster
than the rears, and therefore the driver is used to having slightly less grip at the front. By fitting new tyres to the rear and repositioning the more worn tyres on the front axle, the condition the driver has become used to is retained after the tyre change.
What happens if new tyres are fitted on the front?
The vehicle’s handling characteristics will change and the driver could be taken by surprise. Where previously there could have been a tendency to understeer, the initial loss of grip could be on the rear axle, leading to oversteer, which is more difficult to control, especially on slippery roads.
What happens if new tyres are fitted on the rear?
The handling characteristics will be similar to those to which the driver is accustomed. There will be maximum grip on the rear axle meaning that if the car does slide it will have a tendency to understeer* – a safer and more stable condition than oversteer.
Enter the words "fit new tyres to rear" in a search engine for numerous other similar explanations.
It's a bit techy, but when braking the front end loads up. If you have a front engined vehicle, this will make the back end lighter and thus more prone to oversteer.2006 D3 HSE (Original & still the best)-GONE

Thanks for the replies gents.
Next question is - how are the AT3'S? I know there are some who run duratracs or scorpions but are there many running AT3'S and enjoying them?
Asked for prices at my local tyre fitter and seemingly tried to be talked out of them...
