What are the effects of Bad tyres on a Car?and replacing with another tyres,does this solve it

W age of car..mounts probly worn as well as steerin parts . If shakes wile drivin then tires or balljoints bad..this can b dangerous..u can buy good used tires but b joints can collapse rite on interstate. Seek an old school mech and not a dealr

better than car tires
truck tires are inflated to 100 psi and because of the weight they carry , they generate more heat so the nitrogen is the way to go
unfortunately , tires get punctures well away from any nitrogen pump so it is not cost effective

Three common faults here are;
1) Steering alignment - if the front tyres are wearing on the insides then the wheels are facing toe-out. If on the outsides then they're toe-in. The only way to really get them aligned properly is by laser light at a garage. Cause can be altered ride height, mounting a kerb badly, wear in suspension.
2) Worn part in the suspension system, most likely a suspension arm bush or ball joint has deteriorated, uneven and/or premature tyre wear suggests this is more likely the cause.
3) Uneven tyre pressures or sizes. If a tyre is down on pressure or one wheel is oddly sized then you can get a diagonal pivot effect accross the car's chassis, causing it to pull to one side.This effect can also happen due to a broken suspension coil/leaf spring for the same reason.

Dear Sir,
As you said you have problem with steering wheel drugging while brake, i think it may happen at time when your car abut to stop or got slow may speed between 30 to 20 km/h, if this is case then first replace fr tyre with rear both and then Tyre if problem solve then it is a problem with tyre, it got uneven wear due to imbalance actually tyre shakes and that feeling we feel in steering wheel. and if problem not solve then replace fr both low arm bush and joints. there is only to cause that can make steeing vibrate. i hop after trying this you have soled your problem if any issue please let me know. Thanks.

did you rotate the tires. its possible you have a defective tire.

This is the speed zone where wheel unbalance begins to take effect. Have you replaced a wheel or tyre lately?

replacing one is ok but replace two minimum to create even wear on the tires

1. It's hard to say without looking at the vehicle (and test driving it) but more than likely the front end is badly out of alignment. ( If the car has been in a significant front end accident and badly repaired then this could also be a source of the problem as the alignment may not be capable of being properly set).

2. The first thing to do is take the car to a specialist suspension and steering shop and have the wheel alignment checked and adjusted to factory specs. Normally this is not expensive for a straight forward alignment but price depends on the shop. A good suspension shop will also identify if there are any wear problems with the steering or suspension that need attention

3. Older drivers sometimes frequently hit kerbs when parking their cars. This will throw out the front wheel alignment every time (and damage tyres) so it must always be avoided. Scrubbed.scuffed tyre side walls are an indication of this as well as scratched wheel rim edges.

4. Some drivers never check tyre pressures. Low tyre pressures will cause much greater tyre wear as there is more friction. (It will also make steering heavier, place undue stress on the steering components, cause the car to handle badly and result in much higher fuel consumption).
The lady needs to ensure her car has at least 32 lbs pressure in both front tyres and at least 30lbs in the rear (which carries less weight). The pressures must be set with COLD tyres. Manufacturer optimum spec tyre pressures are usually set for comfort. These can be safely exceeded by a few pounds. It is far safer (and more economical) to run slightly higher pressures than a setting that is too low. (A good tyre will run all day with 38-40 pounds pressure and 36-38 is quite safe).

5. Worn out shock absorbers will also contribute to abnormal tyre wear. 70000 miles of average driving will see out a set of shocks. (Personally I would not leave them that long as the factory shocks are generally of average quality on this type of car)..

That's the best I can do Brad without seeing the car so I hope this helps some. Hopefully a good wheel alignment will fix the problem but make sure the tyre pressures are kept up as well. If the shocks are worn out they will also need to be replaced if the car is to be roadworthy.

Hi,
This could be a combination of things. I'll suggest them and see how you go.

The tyre pressures have the most effect on road noise. Strangely there is more transmitted noise when tyre pressures are correct. Under inflation cuases a cushioning effect, whereas over inflation can make the tyre profile balloon reducing road contact.
Check that they are in limit.

Tyre tread profile can produce a humm if there are straight lateral bars. Good designs use offset bars to reduce this effect.

Cover any loadspace, and ensure sound deadening panels are in place.

Shock absorber top and bottom bushes come in different relilliancies. Hard provide tighter handling - but allow more road noise, soft absorbs noise, but allows more roll.
These bushes harden over time - thus transmitting more noise.

Shock absorber seals can swell enough to make a shock "sticky" - thus transmitting more noise.

Other suspension bushes likewise harden and become more solid with age.

So, - If it is bothering you, Check tyre pressure and condition. Cover loadspace with sound deadening material - A rubber mat in the boot works wonders.
Inspect rear shocks for wear/ corrosion.
Remove and replace bushes with new.
Replace shocks with new if required.
Inspect suspension bushes, & replace if cracked or perished.

This should solve the problems for you.
