Anyone changing just two tyres, maybe see video below:

Running more PSI in the front helps acceleration, but the wheels are stiffer and tends to bounce more, and also, with more pressure, the contact patch will be less on the front tyres. This all contributes to less traction, not more.

Take a bus, use a scooter (as long as you can service it well, it will be safe), walk, bicycle, hitch a ride.

To want to drive a car and not able to properly maintain it, it is not only dangerous to yourself but others around you. I think it is just plain irresponsible. Just because someone has been doing it and it is so often done that it feels normal does not make it the right thing to do.

maybe you’re blessed to be in a situation where in any case when you have to change only 2 tyres it is by choice and not forced into the situation because you are short of cash.

personally i have been in this situation many times before. a fresh grad earning less than 2k, with one of his old satria tyres busted because of a pothole. all tyres are about half thread, cannot just put one new tyre, so only can afford a change of two.

what are you going to do then? will money fall from the sky?

As you’ll never know, as carefully as I can possibly drive. I end up off the road and hit a tree on a rainy day! My airbag pops and saved my life. Now, I really have to wonder with all these accident bills ahead of me, Was the $300 saving worth gambling?

Even worse, I could end up in a wheelchair or die.

If I want to save money on car, I’ll save on other stuff. Not on tires. SERIOUSLY, is a bad advise.

to my curious ,in this condition where front tyre are new and rear with half tread. during wet road or go through puddle of water at normal speed, the front tyre with full tread will sufficiently channel out the water on the road and when the rear tyre come to contact , the road is in nearly dry condition .so the rear tyre will have enough traction on the road already.

just my 2 cents opinion.

for my FWD car, i usually start out with 4 new, as the fronts wear out faster(usually the case with FWD), push them behind, and put the better condition rears up front. As the fronts(previously rear) wear out, either push them back, get 2 new fronts, or totally buy another set of 4.

a FWD is naturally understeery(unless setup to oversteer on purpose), so its always a must to have better tyres up front.

most importantly, always check your tyres constantly. if they’re damaged, or are worn near to the thread depth indicator.. change them.

after tyre warmed up,
the compound is softer with temperature, so itd be able fill to the finest bump and lumps could therefore giving greater friction /traction or grip,

if it in case of wet tire, tread design is important here i guess,

well tyre compound play an important role as well,
cheap tyre -harder compound, last long, noisy, might less sticky, crack might persist if old,
not sure about its steel belt, good quality or not, might related to ‘swollen’ case.

The Parada S2 is great in the dry, but on slightly damp surfaces, a bit of caution is needed. In heavy water, the Paradas work great.

New tyres have to be scrubbed-in to get good grip. Usually a few days of hard driving and a few heat cycles will bring grip to maximum.

With significantly grippier parada’s on the front, you can get into a snap oversteer under braking if you are not carefull. I use Parada up front and worn out FTZs in the rear when I go into “drifting” mode…well, since I’m FWD, its more like a$s-dragging than drifting.

This is NOT something you would like to have an unintended experience on public roads.

Normally i would rather buy better(with a little extra RM) tyre… 2 or 4 depends on pocket but cheap tyre should be avoided! Especially those unknown brand, we’ll never know what are used to made them and most importantly does it perform and reliable enough….

by no means am i suggesting you leave the front tyres in extremely worn out condition. it’s just that usually the front tyres wear out way ahead of the rear ones and the rear ones end up still having some decent thread left, so people in bad financial shape choose to change only 2 instead of all 4.

this is a middle ground some choose to take and this article teaches you how to achieve that middle ground in the safest way possible. not everyone has money.

you’re welcome not to take this advice and continue with what you are comfortable with.

Just because if you have 2 new tyres up front, does not mean it has better grip.

Yup, I had experience that on my 1 day old Yokohama Parada spec 2 on my wira in wet and slipery (Tar road stones very fine/halus) road.

Any idea what might caused that to happen? Rear tyre was my old sime tyre with less than 1/2 tread left. Speed that time was 60km/hr on a slight 70 degree cornering (AKA Long corner).

Current feedback i got was the new tyre not yet reach its working grip surface. Is it true?

This is the worst advise I’ve ever heard!!

OK, you believe that spinning is more dangerous than understeering. Well, I reckon both are dangerous and there is NOT better scenario!

However, I do reckon front tires should be new. WHY? In dangerous or slippery conditions and suddenly you loose it. A normal driver instinct is to brake. We all know that front tires always takes the majority of braking power. Just have a look at your front brakes or front brakes of motorbikes.

If you have front bald tires, rear new ones. well, if you’re lucky, you’ll just end up in a ditch. But we all know it can be worse.

If you can do make sure all 4 tires are in good condition, but if you must, do make sure at least the front are grippy so that you can actually stop.

so for a normal driver at least get a Goodyear made in malaysia, good enough,

This is especially those with permanent viscous coupling centre differential type system.

Having even slightly different sized tyres can seriously screw up your AWD system.

If i was going to pick a nit from this post, having less thread at the back is just as bad, as if you were to run into a puddle, lets say on a bend, the worn out rear will be hydroplane more (its lighter out back there as well) and cause oversteer.

Besides, most people’s gut reaction to correct for understeer is to jab the brakes, either making it understeer more or going into snap oversteer. Even throttle lift off may cause oversteer as there is “no weight” at the back. My car is precisely tuned for that behaviour at the track. Throttle lift off will cause the rear to rotate out to compensate for understeering front during wet track days, on dry its tuned to neutral.

I remember we used to put sand bags (road salt..etc) in the trunk to keep rear end stability during winter.

and most people would find its rear with the least half thread, which is not too bad for grip, and not to the extend they are ‘bald’,

anyway rotate the tyre regularly makes tyre wear evently, is a good practice,

-always check the ‘flower’ of your tyre,

Just because if you have 2 new tyres up front, does not mean it has better grip.

A couple of track sessions per year means I go through about 2 sets of tyres per year. Being a FWD means the front end is a pig. I tend to use different brands front and back to allow for handling differences for a looser rear end. Having “sport” allignment setup that is “off spec” also contributes to the wear.

Most importantly, your tyres must match your suspension/allignment and driving style.

Total contact patch area for most of our cars is about or less than an A4 sheet of paper. Food for thought, eh? Think about that the next time you would cheap out on tyres.

It is best to change all 4 at once, but as thats pretty heavy on the wallet, as long as you rotate and have your allignment and tyre pressure in check, tyre wear can be fairly even. It is usually advantageous to run a few PSI more than the recommended tyre pressure on the front end for more grip in corners.

That said, If you are charging into a corner too fast, no matter what sort of tyre setup you have wont save you. So drive safe.
