sleep envy said:by the nature of 911's design the rears wear 2 to 3 times quicker than the fronts
on my 911 my fronts last twice as long as the rears mainly due to my driving style - therefore I replace all four, then just the rears and then all four and so on and so forth
at no time will the front have a greater tread depth than the rear
hope that explains your question
now back to the FWD issue...
sleep envy said:what do you think happens when you have less understeer?
it turns into oversteer as the front end grips
then you have the part worns on the rear, the **** of the car goes loose and you go straight to the scene of the accident
seeesh!
do you really know what you're talking about?
marriedblonde said:Perhaps we need a new poll. Who here has died because they fitted new tyres on the front of a car?
I for one haven't. Any one else?

marriedblonde said:Ok so answer me this:
If you have a porsche or BMW that uses staggered tyres fonrt/rear are you saying that you can't replace the front tyres without replacing the rears?
Obviously you can't rotate tyres if the fonrt and backs are different sizes?
Or are you saying that I need to drive at 15mph until the tyres are worn approximately the same?
All modern cars, bar a very few, are set up to understeer as this is safer. True or not?
bowfer said:FWIW, I'm on my third set of fronts tyres.
They've been Continental, Goodyear F1's and, currently, Dunlop Sportmaxxes.
For 90% of that time, it has been the original Continentals on the back.
I recently moved part worn Dunlops from the front to the back and put nice new Sportmaxxes on the front.
I've never noticed any grip problems at the back.
I've even tried to induce oversteer, because I like it.
The thing won't budge!
This scenario has been repeated over loads of FWD cars, over 23 years of driving.
Never, ever, noticed or regretted leaving part-worns on the back and putting shiny new ones on the front.
TBH, I don't care with supposed tyre experts or 'science' tells me should happen.
Practice tells me, for a FWD car, it pretty much doesn't matter what's on the back, they'll grip just fine.

marriedblonde said:What absolute ******** your now talking.
If that was the case the law would be changed. 20/30 years ago I dare say that might have been the case, the same as the problem with radial and cross ply tyres.
Manufacturers couldn't take that risk. Tyres places wouldn't fit new tyres to the front of cars.
No one is doubting the theory, but the reallity is definately different.

sleep envy said:really?
why do you think manufactures dial in more understeer to cars?
phantom said:For most people day to day driving with the odd blasst , it will be better to put new tyres on the front, to give them more grip when cornering , it won't result in any problems!
If your a keen track day driver or you take your car to hell on your private B-roads then putting new tyres on the rear is a good idea

marriedblonde said:So if a car understeers, does fitting new tyres on the front will eliminate it?
sleep envy said:you can't eliminate understeer by solely changing tyres - you can only decrease or increase it
chassis dymanics are influenced by far more things than just the tyres
bowfer said:put your shiny new tyres on the back, where the increased tread depth doesn't do any good.
Your money, your choice.
marriedblonde said:So a car with new tyres on the front and worn tyres on the back will understeer still?
marriedblonde said:How many people have personally oversteered off the road due to worn tyres on the back?
I've experienced lift off over steer many times both during track days and driving on the road. Not once have I crashed and killed myself, or even gone off the road through a hedge.
So are you saying I am a god of driving? Or a driving god...

newbiecrg said:Well each one is entitled for they own opinions and I am not trying to convince anyone.
I think some people are trying to go to extremes and the only thing I am saying is that worn tires in the rear + new tires in the front make any car more prone to oversteer (wich is a more difficult behaviour to control for most people).
Well it does not mean they will oversteer but, given the right conditions they might. Simple as that. Not saying it is life threatning or anything and I am no example as I change whatever needs changing but I know that for the normal driver (80%) of us it is safer if they have the best tires in the rear.
what is amusing me is that everyone that says front or doesn't matter either do not give proven facts or simple physics, instead when asked why just answer because.... or others claim that never mind what science proves I know what I experience... Fair enough on both.
Sleep envy, sometimes your positions are a bit extreme as well lololol but in this case you are spot on... and, like me, you understand that tires are one more thing in the equation and not THE thing... I say more or less prone you say decrease or increase which is the same thing...
All this can be measured, and has been by all tire manufacturers, on a race track with a lateral g sensor (so the load put on each set of tires is the same)
But has in health increasing the risk factors does not mean we will have the disease... I think most comments didn't had the disease...lolol but they still eat fish and chips everyday...lolololol Some getaway in a lifetime, others don't...
Anyway as far I am concerned this topic had all the opinions covered so no point carrying on.

sleep envy said:you are deliberately missinterpreting the posts
marriedblonde said:Not at all. You and Pedro are saying that a car with worn rears and new fronts is POTENTIALLY dangerous.
marriedblonde said:Perhaps Pedro and Sleep envy sould like to get a room to continue thier loving?
