Can anyone tell me when you replace two tyres, they should go on the front or rear?

I have just put two new ones on the rear, identical replacements, correct pressures and its feels like its wandering around like a pig on a lead?
Replaced drag link & ball joint a couple of months ago for MOT, but this has become apparent since new tyres?

Thanks in anticipation.

It could be the differrence in diameters between the front and rear tyres, try moving one new tyre from the rear to the front axle, the new tyres will be trying to push the vehicle faster than the old ones are pulling and the center diff/coupling is having to adjust for the differrent in diameters.

Its doesn't matter which corner you take it off or fit it too, just move one wheel from back to front, by doing this you are moving the diameter adjustment from the center diff/coupling to the axle diffs.

Dunno, but I once saw someone with a sheep on a lead in town. And up in Londin too, not in the country. I'll try n find the photo.
 
I always replace all the tyres..however if you only replace 2 any garage will tell you that the new ones go on the front..
 
Can't comment where the new ones should go on a 4WD vehicle (front drive is on the rear), but most importantly- tyre pressure. Tyre firms are renowned for setting pressures incorrectly, something to do with "most are about xxxpsi so this one must be xxxpsi as well" mentality. I'd check them yourself with a reliable gauge.
 
The logic behind tyre change is that they should always be done in pairs if two wheel drive and as a set of 4 on 4 wheel drive cars.

Have to agree with rob - most garages will say put the new ones on the front, this is because most garages deal with front wheel drive cars most of the time. On front wheel drive cars in particular you are asking the tyres to do three jobs: Steer, drive and brake. Therefore it's best to have the best tyres (e.g. newest) on the front. With rear wheel drive cars, most have large rear tyres, but if they don't then the newest should go on the back. However on the Camaro I owned the workshop manual suggested the wheels be rotated from corner to corner at every service (rear wheel drive, but all same size tyres).

So back to 4 wheel drive cars, it is always advised to get sets of 4. As zzr said, you are just making the diffs do more work than needed and eventually this can lead to damage to the diffs if they are out too much between front/back or left/right.

True it is cheaper to purchase two tyres over four, but replacing diffs can't be that cheap.
 
The reason for putting new tyres on the back of a front wheel drive is, despite them doing the most work, if either axle looses grip, the rear is the worst with the car doing a 360 quite easily, but the front generally just means under-steer.

That's from an old guy I know who's been running his tyre business for many years.

I'd have thought the main criteria for controllability would be:

ratio = widest point of head / narrowest point of neck

No, these are vermin and should be exterminated on sight before all our cows get TB again and people start dying from TB in milk products. Seeing wild animals is what Zoos are for.

We Brits seems to have forgotten what the word Vermin means.

There's a whole bloody society in Brit land that thinks badgers are the supreme from of life on this planet. Another society says it's crested newts, and others say it's pearl-bordered fritillaries or red kites or bloody buzzards. One lot up here has caused havoc letting great big sea eagles loose. These think it's fun to scoop up small lambs, take them 200 feet up, and drop them. One farmer (like ONE farmer) lost 200 lambs last year to this, and they would jail him if he even shouted "BOO" at those monster feathered killer vermin birds. Grrr........ we should be blasting the brutes out of the sky.

They should leave countryside ecology to the countryside people who have to suffer the effects of vermin. Townies should get no more involved with animals than seeing them on TV. Did you know that about half the population cannot see the connection between cattle and sheep looking pretty in the fields, and the meat on the supermarket shelves?

Rant over.

Sorry.

No I'm not ....
