Effect of tyre type on noise

Ok yes that could be the problem it could also come from lack of rotation

on fwd cars the rears mostly are there to hold up the back end, if left on the rear too long they will scollop and when moved to the front the noise will be louder

on independent susp they atleast move a little.

It takes a good ear to tell the diffrence between a bearing noise and a tire noise

with the new cars using sealed ball bearings they are harder to diagnose over a tapered bearing noise. at my shop we have the old spin balancer which makes it easer.

normaly a tire with a more closed sipe will make less noise but not a good rain tire

It takes a good ear to tell the diffrence between a bearing noise and a tire noise

Just wait a bit and the bearings will grind and screech!

Different tires have entirely different characterists, noise being but one.

Road surface also make a great difference, and different surfaces (rain grooved, rubberized asphalt...) interact differently with types of tires.

Just my 2 cents

several thingfs you don't include

air pressure'2 age of the tyres 3 how long they were on the shelf 4 when did you get the front suspension checked 5 did the check include rotation and dynamic balance testing 6 what is the total wirgt you are putting on the car at that sped 7 waht condition are the rims in those are things you have to consider for starters'da ber

Why do you think it's the tyres.

Car two months from new? or just two months to you?

Tyres original on vehicle?

Could tyres be on backward

What type car?

What else could it be?

Yes, the car (Honda Accord) is two months from new with original tires.

Thank you for those clarifications, the questions as to which was leading to one idea: that it could be an issue to take up with the selling dealership and/or manufacturer; it being the case that mismatching of tyres to chassis is always a possibility. If it is the tyres, the dealership/manufacture might just have some awareness of the situation...and be amenable to considering exchange for a better tyre match.

The question, "What else could it be?" is a loaded one, as I'm confident you are aware...because it could be so many things, both, tyre related and unrelated; to name just a few (acting independently or in concert) (some which, with due apology, have been offered previously):

• A problem with wheel/steering alignment (brought about by road damage conditions)
• The acoustic and dampening properties of (small) Accord chassis/body
• Road surface
• Others things other than the tyres, such as a partially open window or an air "leak" in the weather stripping...(think about the correlation between noise & noise frequency and travelling speed...through the air)

Of course, noise is not always an easy thing to isolate. Often when I have what I perceive as an "inside noise" driving my car, I try to hear if from outside...first by opening windows; next by driving (at whatever speed) along a curb or jersey wall on a (California) freeway. This has the effect of echoing back noises with origin external to the occupant compartment...such as wheel, tyre, and road noise. A passenger can provide further pinpointing help.

I'm sorry I can't provide more specific help regarding your Accord's problem. My experience with these is limited...other than to say that (to me), and like many smaller cars, they can seem noisy, especially at higher speeds.

As someone who puts on 70,000 miles a year on a car for the past 20 years, I have tire experience.

The road surface is the biggest variable for a single speed.

Is there vibration in the car ?

Is the vibration in the seat or in the steering wheel ?

Brake rotors can also warp and cause a vibration, I never allow replacement rotors from China, have only got 15,000 miles versus 60,000 for US or Canada made rotors.

Sometimes there is tread seperation between plies in a tire that is difficult to determine, numbering the tires and then rotating them to see if the problem moves?

I only rotate front to back, always maintain the same direction of rotation, rotate every 5 to 10,000 miles.

Obviously almost all of my travel is 60+mph.

I have a 03 Ford Focus that I have 190,000 miles on as of a year ago last March, I put high speed snow tires (Bridgestone Blizzak) all around and was getting 60,000+ miles to a set, the car always rode rough unless loaded which it usually was.

I've had no-name tires get diagonal ribs at less then 10,000 miles and replaced them.

I would make myself a pest at the dealer, have them look for recall notices on the tires.

Is the noise really significant, louder then a truck tire ?

Well, he did say high frequency and above 50 mph, so it sounds like a classic case of tires singing. Yes road surface makes a difference. Concrete seems to be the wors offender and if they groove the concrete it will make any tire sing.

Good answer back at 1. Those people are real experts at tires. They have guided me on three separate occasions, all were excellent tires over their life. One trick I have learned over the years is that letting the noise reflect off something works very well. Try driving next to a row of parked cars, or a wall of a building. Even a raised curb will help. I find that I do well when I stay 6 to 8 feet from the wall or row of cars. A bit closer for a simple curb. If the noise is from the tires, wetting the road will change the sound dramatically. At 50 mph I would think that would require waiting for rain. One last thing Back in 73 I bought a car with Uniroyal tires on it. The tires would squeak at lower speeds.(Under 10 mph) It turned out the tires would rub against the bead area of the rim. It left them looking like chrome at 40,000 when the tires were changed.
