tyres

Don't drive so fast, there is a spell check available on CR4 now,

I have a truck that had very hard (and old) commercial tires on it when I purchased it. They were incapable of driving straight down the road; every defect in the road would deflect them. I changed to new tires and the problem went away.

Yaw can be caused by many things including tires that are over-inflated, under-inflated, too old and therefore too hard, Suspension misalignment, overloaded vehicle, high crowned roads and heavy crosswinds.

Don't know where the car is located but unless the tires are in the sun all the time, they shouldn't be too hard.

Test the tires for hardness by trying to poke a small diameter rod into the tire tread. Then try the same on a new tire. You should be able to arrive at a rough estimate about their condition.

Thansk for the idea i tried thevpoking method and found it rather bad I have replaced the tyres Wow what a difference the wheel works as if its a power driven steering.

Keep up with the good work.

It also coyld be the new mixes of asphalt. They are using recycled plastic in the mix now so your yaw could just be sliding on a slicker surface.

Rubber tires do harden with age - if fact most rubber does. Your tires are 8 years old and have been exposed to heat , UV , and various compounds in the atmosphere such as ozone that take a toll on rubber. It is time to replace them. Ed

You wrote quite a lot that I am in full agreement with, but you also wrote:-

Rotate your tire crisscross and front to rear.

Which is downright dangerous as you neglected to also mention that some tires are directional and would need to be turned on the rim before being placed on the other side.

I had an aquaintance who put a set of direction tires on the wrong wheels one winter, the car aquaplaned off the road and was a write off, luckily the insurance did not spot that the tires were on the wrong wheels or he would have not got a penny back!!! I noticed it when he was showing me fotos of the wreck!!! (Which were taken by the insurance assessor!!)

Please make sure that your posts are "safe" in all respects in the future, take a minute to read through what you wrote before posting.....

Thank you Andy Germany,

I did think about that exact point, and agree that older tires did have this problem. Newer tires on average passenger cars don't have this problem that I am aware of. Being a 2001 vehicle, low mileage, I would believe these tires to be about the same age.

There are directional tires that can be rotated only front to back, and I did neglect to mention this, but these tires are clearly marked on the side wall. These tend to be more of a specialty tire, and usually found on more expensive vehicles.

I did look it up before posting, and found several sites that will agree with me.

I do hope that anyone who looks to these posts for answers, under any topic, read all comments, and take them in as a whole, and not just follow the direction of just a single post. It is necessary that they use their best judgement, as even though they are seeking an answer to something they don't know, and are asking a forum of people more knowledgeable, they are ultimately the "expert" for their particular problem.
This does not mean that people on CR4 do not know what they are talking about, there are some brilliant people here, but that the original poster of a thread may have omitted details that would have created a different response.

Thank you again Andy, I will try to be more careful in the future.

OK no problem.

I suspect that I am a little sensitive on this point as here in Germany we still have no blanket speed limit and quite "normal" cars are often fitted with tire that can clear a LOT of water at high speeds, these are mostly directional tires. If travelling at an average of over 100MPH, as lots of us do when in a hurry, it gets to be quite important!

I suspect that in countries with blanket limits, this type of tire is not sold so often.....though of course they work best under such conditions of water, no matter what speed you drive at.

With Guys like yourself on CR4, its a pleasure to converse with you at any time, on any subject.....

Also, CR4 is Teamwork, we have both just demonstrated that point clearly I feel !!

....and that is NEVER "OFF TOPIC"!

Thanks Andy for all the information on my tyres Ill take your advice and follow up with the Technician at the4 garage.

thanks

Wow, you really are amazing. Can I have your autograph? Your a real Sherlock Holmes. I bet all the girls down the pub just love to listen to your stories !!!!

Was the aquaintance called Andy Germany by any chance ?

As you signed on as a jest guest, I am unable to know which Del you are.....are you brave enough to sign on properly and come out from behind the "bushes"?

Dear andy,

I didnt quite understand your query well I live in India Kerala to be precise my real name is Venu I have come out of the bushes if thats the way you put it and am wlling to face an ambush.

Thanks for all your valuable comments.

Crisscross rotation used to be standard, before radial tires were common. The reinforcing plies in a radial tire take a set over time. This causes greatly increased tire wear until the set is reversed if they are placed on opposite sides. Rotate radial tires front to back, but keep left left and right right. (For those of you across the Atlantic, tyre=tire)

Hardening of the tires might cause this, but tends to cure itself after driving for awhile, and would be noticeable at all speeds.

FLAT SPOTS caused by the car sitting idle for a while tend to disappear after driving a short distance.............. but once the rubber compound has hardened those tires are past history - replacement is the only option - they are 8 YEARS OLD - you got your use out of them regardless of how many miles are on them. If you got a flat on one of these tires most of the tire shops in my area would refuse to fix it because of the age of them and liability concerns.

Hello, also on the tire sidewall there are code letters and numbers that give wear,traction,speed rating, load/pressure rating.

The tire shop or online mfg. site can help with the coding spec. for your brand.

As tires age they can "dry out" and get hard. The rubber oxide by losing chemicals that evaporate. Also some tire shine compounds can cause problems in making tires age faster.

Last than If you like to drive fast there are performance tires that should fit your car.

You will need to look to make sure the tires meet the minimum standards for your car.

Like weight and size. By going to a performance tire the tread may wear faster than a stock tire, less fuel millage is possibility. But your car would have better grip on the road.

If you went with a different size tires on your car like a wider tire there a "+1" or "+2"

that means by increasing the rim size by one or two you can have a shorter sidewall than stock with the same tire diameter unless you already have low profile tires on the car.

If you can fit a wider rim and tire under your car that can help with stability. A lot of after market rim dealers have fitments guides that may help you with what will fit under the car. Or you you can measure clearances around the stock tire and inside the wheel well at full turn left and right on the inside and out side and you can usually add a little rim width to the outside and maybe a little on the inside but measure, measure, measure. Also don't forget about suspension articulation and fender and tire clearances. Any pinched welded seams or fender edges can be bent over for a little added clearance to keep from possibility cutting the tires.

If there is a good after market tire and rim shop in your area they may have a jig that holds a tire you would want and it bolts to the hub and it's sizes the rim width and back spacing and front spacing.

Hope this helps you and It sounds like you may need new tires, look closely at them on the sidewalls and in between the tread for small cracks if there are some the tires are dry rotted and Should be replaced or limited your speed as the tires can fail at speed. As they age the may start leaking air also that is another sign the tires are getting old unless theres a hole in the tire.

Look at the side of your tyres for the production date of your tyre. The production date is mentioned as the week number and year in an elliptical (or oval) shaped marking. Every tyre must have this marking on the side, whether you live in the US, Europe or everywhere else in the world.

If production date is more than 5 years ago, your tyres need to be changed immediately due to rubber hardening.

Hello venuiji,

Hardening of tyres? The inside or outside

I would suspect either wind, wheel or frame alignment, weak dampeners and or speed too high for conditions.

Be careful here. Wrong information abounds in some of these posts.

Before anything else, get the tracking checked and adjusted at a reputable local (work)shop.
