> On wet roads, you'll get oversteer and perhaps spin out more easily with better tyres in front.

 

i.e. more threads in front make the front turn more effectively, and less threads behind encourage tail to swing out?

OK he is right in some way but people need to get used to the idea you can actually manipulate how your car behaves from the tires.

 

For example, thinner tires in front gives you better steering response. This will translate to reduced understeer (more towards oversteer).

 

The same effect can be experienced if you pump up the pressure for the front tires (smaller contact patch).

 

Reverse the situation with a fat tire in front and a thin tire behind you get the opposite. You get more understeer (away from oversteer). Ditto with tire pressure.

For this reason. I don't rotate my tires. I want my front ones more worn than the rear. I buy new tires to fit to the rear while the worn rears take the front.

Not true.

 

Tyre rotation is to even out the wear of front and rear tyres. Frankly, useful only if you drive hard and you use better tyres that costs more. This is simple remove four wheels, front does to back.

 

Wheel alignment is necessary only if you do things like change suspension/coilover etc, when the wheels may not be aligned perfectly in a straight line. Also look out for camber angles. This is done by computers on platform.

 

Balancing is typically done when you change wheels. It is to balance your wheels so that they will not vibrate at high revolutions by adding little counter weights. This is done on individual wheels on a rotating machine.

Hi would like to check whether do you happen to know why when travelling at high speed and when you brake,steering wheel vibrate alot. but at low spped it's ok,pls advise

2 possibilities:

 

1) Your brake rotors are warped. Check and change them.

 

2) Your ABS is activated when you jam brakes at high speed, hence the "stuttering" effect as the ABS works (on and off brakes very quickly) to bring you to a stop without skidding.

Hi ,

 

Anyone know where is the cheapest place for four wheel rotation & balancing ?

 

Thks

 

Bro,

 

Balancing got 2 types.. ON-Veh(aka High speed) or Off-Veh( on the tyre machine one)...

 

Off-veh is done on the wheel alone, while On-veh is done including the whole car.... got diff one...

 

For alignment, sometimes if u ever kenna big potholes or kerb side swipe, it is possible for alignment to be a bit out....

 

Note, not all shops do On-veh balancing...

For wet roads, it'll be different due to aquaplaning characteristics with respect to contact patch area(I'm talking about wet conditions anyway).

Personally, I prefer consistent handling both in the wet and dry, so typically I used pretty close settings for the front and back tyres, depending on the tyre wear characteristics as well.

eh, i thought the other posting said more thread (more grip) in front means better steering response? ... so .. u say more worn tyres is better response. confuse liao.

 

ur idea very good, change 2 tyres at a time. i'll try that but i'm changing rims so will be difficult to change 2 rims at a time hehehe.

 

btw if hard turning left all the time, will that wear out front LEFT tyres outer-thread or front RIGHT tyres outer-thread?

[smallcry] any idea how much does it cost to change? if didn't change will it have other side effect or cause other stuff to spoil? confirm not the ABS cos i didn't jam brake, i only brake a little to slow down

 

[thumbsup] Thanks pal
