I know quite a few people swap the tyres round when the fronts are wearing down compared to the rears.
I am sure though I have read you should have the newer tyres with more tread on the rear (assuming fwd).
I had a new tyre over the Christmas breack and specifically asked the question about which should have the most tread, front or rear. The shop manager said that the tyre manufacturers recomendation is to have the most tread on the rear as a front wheel slide is easier to control.
My personal opinion is that it is best to have even wear on all tyres, and try to rotate them, so that all 4 need replacing together.
I've always put the ones with most tread on the front, and moved the old fronts to the back when the backs wear out. Don't drive agressively enough to cause the back to slide out, and if it were to happen due to grease / oil, no amount of tread will solve the problem.
Each tyre wears in to the corner of the car it is fitted. The front tyre has to wear into being steered as well as suspension movement. It has always seemed to me to be a detrimental step to swap tyres front to back. They then have to adapt, by wearing relatively quickly, to the new corner they are fitted to. It seems to make more sense to me to leave fully bedded in tyres on the back even though they will have less tread than new fronts.
"I put the new tyres on the back, then put them on the front when the fronts wear out. That way I'm only paying for two tyres at a time"
That seems the best scheme if you are persuaded by the tread-on-the-rear theory. One point to remember if you do a lowish mileage is that tyres should be rotated so none of them gets more than 5 years old. Personally I prefer tread on the front, as I don't drive in a way to risk rear breakaway. A more likely event is aquaplaning on a drenched motorway, with the need for quick braking. What use deep tread on the rear then?

More tread on the rear will stop the car from wanting to swap ends.
I still prefer to have more tread on the front of a front wheel drive car, but having driven a Caterham 7 for a year or so I'm very used to controlling rear wheel slides. Unless you're very used to driving a tail happy rear wheel drive car, stick teh most tread on the back.
I read often, only post occasionally
whilst I try and maintain a balance on the 4x4 I always keep most tread on the front of the mondeo. In reality my tyres always wear on at the front simply due to the fact that I corner at relative speed.
This old chestnut. Do not rotate tyres, front to rear if you really want to but not sirde to side. Some tyres of course have a rotation requirement and are marked with an arrow, but all tyre develope a feathering pattern in the tread due to the direction of rotation and wear. It is easy to detect just buy rubbing your hand around the tyre, one direction is smoother that the other. If you swop it's rotation is presents a less efficient contact with the road until it has worn off the wear pattern so you eat more tyre for no good reason. Ok sometimes you move from to rear due to a tracking problem you may have now fixed but again not side to side. I know what the tyre people say about best to the rear but I prefer my front wheels to go where I point them. Tread depth verus traction is big subject but between 8 and 2 mils it is very difficult to judge the difference. New tyres are a bit slippery for 100 miles or so and tyres down at 2 mils in the dry are great so how do you balance that. Regards Peter
