Re: tyres on front or back


Good vid but that granada crash they show a tiny clip of was caused by a dual blowout at the rear(its taken from police camera action and they chopped the start so you can't see the car driving straight in dry conditions then suffer a sudden blow out and turn right also wasn't a police pursuit was just driving past a cam car when it happened) nothing to do with wet weather handling do wish they wouldn't bend facts like that.
 
Re: tyres on front or back

On my Sei I replaced the rears for new as the fronts were ok. I found that the fronts were really spinning up to easily so I put the new ones on the front and it transformed the car. Although I mentioned it spinning up I dont drive hard but I dont hang about. So I guess my opinion is new ones on the front, when they wear swap them over and when all 4 are worn replace for 4 new tyres. Then start the cycle over.
 
Re: tyres on front or back

Right I've raced both karts and cars, and believe me oversteer is easier to deal with than understeer. Therefore best tyres on the front (front or rear wheel drive).

If the car loses the front end, all you can do is slow down enough to a point where you hope that the tyres regain grip - and as you head staright for the farm gate on a 90 degree bend with your wheels locked your next point of retardation will be the gate.

Where as if you lose the back you have at least half a chance of catching and correcting it (opposite lock and back off the throttle on a RWD car, opposite lock and more throttle if a FWD car)

By the way it doesn't show you the white car trying to anchor up suddenly and fying straight off the road.

Re: tyres on front or back

Id put them on the rear mate....trust me you dont wanna be oversteering, especially in this weather! Manufacturers even make their cars to slightly understeer as its MORE controllable.

Tell you mates this....if you put the tyres on the rear you're more inclined to understeer yeh, but you have the braking and turning of the front wheels to control that. If you oversteer, what have you got really? I think you'd be silly to put them on the front in my opinion.

If you can only afford a pair atm, id push the boat out and go for all four's. Tyres arent something you should skimp on imo.


:yeahthat: it makes all the diference, i used to place new tires in front, after a couple of undesired drifts, i decided to switch them to the back... like flexywozere said, it's easier to control understeer than oversteer.
 
Re: tyres on front or back

Well I have to agree sudden breakaway and oversteer on a front wheel drive vehicle is dangerous actually, Iswapping the tyres, doesn't really help, I had a mate who did this, and he almost thrashed a hedge, but if yo wanna risk it, then be my guest
 
Apart from the grippy discussion, putting new tyres on the front leaves the rears on the car too long and they run out of their "best before" date, at which point they must be thrown away. New on the back also has the effect of swapping back to front at more or less frequent intervals. It's a legal requirement in Switzerland to put new tyres on the back.
 
Re: tyres on front or back

All the inbreed Norfolk people seem to think you put new tyres on the front

Well, being that they all drive tractors, usually the front and rear wheels are not interchangeable, unless they have a JCB Fasttrak, so how would they know?

I find that with hard driving, the rears wear on the inside, the fronts wear on the outside, so a front-to-back swap half-way through seems to work well. At 3mm they are thrown out anyway, so the maximum imbalance would be 3mm to 8.5(ish)mm anyway. It is below 3mm when a tyre's wet handling characteristics really start to change and that front-back asymmetry becomes really noticable.
 
New ones on the front, then about half way through their wear, put them on the back and get new ones for the front.

Never had a FWD car oversteer in 35 years. If that happens it's already "good night."
 
That'll be a RWD BMW, a RWD Oldsmobile and 2 RWD Fords. This smacks of "Unsafe at Any Speed".
On a front wheel drive car put them on the front, as the rears are only there to keep the arse off the floor.
Pretty much sums it up

Karts are RWD, and I suspect most racing cars are also RWD. If someone's spent a lot of time on the track, they may be able to detect the onset of oversteer. In most cases they haven't - so they can't. Ever noticed on Police Camera Action how the number of thieves that crash cars after getting it going sideways outnumbers those who plough straight on?

If you go sideways into that 90 degree bend you'll just end up going sideways into a tractor instead of forwards into a gate. 100kg gate or 6,000kg tractor? Er, tricky one that.

Without an awful lot of practice, almost nobody can control oversteer at high speed as once corrected, the car almost always decides to have a bit of a laugh at the driver's expense and flip the other way. Understeer simply needs a gentle reduction in speed and a little more lock.

Quite agree. A RWD car has driven rear wheels, the clue's in the name, therefore the driven rear is more likely to start overtaking the front. In a FWD car that starts to oversteer, very rare, only luck and the forces of nature decide if and when the back end goes back in. In a RWD car you, if you're good enough, decide by the amount of drive you put through the rear tyres. Incidentally, if a FWD car does oversteer, it's because the car has already started to understeer and you are failing to correct properly.

Yeah put the new ones on the back, after all they need the traction and take most of the braking effort and steer the car.....hang on.
Yeah, dead right, traction, steering and most of the braking effort go through the rear of a FIAT.....hang on.

Re: tyres on front or back

i always put new tires on the drive wheels but that just may be for me so that when i am pulling away from junctions rather quickly i dont get the wheel spin as much mind in the wet it never works lol. but overall i always say put the new tires on the drive wheels
 
Re: tyres on front or back

Just had another thought on this. I suppose some preference depends on the brakes you have at the rear. If you have drums at the back, which are less progressive and have a tendency to suddenly bite, you are better having your good tyres on the rear. If you have discs at the rear, these are more progressive and less likely to lock, so the argument for best tyres at the back is less convincing.
 
The reason is simple, since the rears wear less (on a FWD) the rubber has aged more and so you put the fresh rubber to the rear and wear down the older rubber.

This of course is the reverse for a RWD car.
 
Let's have another go at this then.

Most cars are FWD, so which part of the car carries the most weight? The Front. In a Front Wheel Drive car it's about 60% Front, 40% Rear. Stick a couple of people in the Front and the difference is even greater.

Which tyres carry most of the braking effort? The Front.

Which tyres provide the bulk of the braking grip? The Front.

Which tyres provide almost all the steering grip? The Front.

Which tyres provide all of the traction? The Front.

Which wheels should the new tyres go on? The Front.
 
Gotta agree with "The Beard", only way you're going to get enough inertia on the rear to make it let go is if the road turns sharply over a crest and you're nipping on a bit. Driven FWD for 30 years including some road rallying and thats the only way I could make it happen.
Driving on ice also does it but so rare it's not worth planning your tyre strategy around !

There's an assumption here that brand new tyres grip better than scrubbed-in tyres, which is wrong. Given that a tyre has enough tread left to drain properly in the wet - which it always must have - and that wear across the tread is more or less even, it will give best grip the less tread it has - that's just described the tyre off the back of a front-wheel drive vehicle. Put new ones on the back to scrub them in - and to conform to the law in some countries - then put them on the front to prevent the rubber becoming too old.
