My rear wheel/ breaks are making a progressively louder noise. It sounds like tread noise, like I have my winter snow tires on. I have 62,000 kms ( 40,000 miles) on both the rear brakes and tires. Front brakes and rotors replaced last year. Inspected the tires-fine ( no stones or nails in the treads). Any thoughts?

Re: rear wheel/brake noise
First check condition of discs and pads if all is good drive and pull up handbrake slowly to see if its the handbrake shoes making the noise if still a problem will most probably be rear wheel bearings

Hi I'm Peter, most of the time when you have high noise from your tires it is related to the tread design. The more aggressive the tread the noisier it will be so if you have all terrain or mud/snow tires they will be a lot louder than a highway tread. Talk to your favorite tire dealer and tell them you want a really quite tread. Unless you are doing some serious off roading a quite highway tread is fine. I can take my 2 wheel drive pickup a lot of places some people are scared to take their 4 wheel drives. Smooth and quite is the way to go. Nice car !
Check wheel bearings. Properly jack up the car one side at a time with blocks set in front of and behind the front wheels with the car in Park. Do not set the parking brake as this will prevent the rear wheels from being spun while off the ground. Safety consideration--- Do not get any body parts between the wheel and finder or under the car in case it slips off the jack---- After one rear wheel is slightly off the ground begin to spin it and listen for rough / dry/ popping noises or break pad drag. See if the noise gets louder when you spin it faster or one direction versus the other. Check for loose bearing by trying to wiggle the tire side to side and top to bottom. Pay attention to tire wear. If you find nothing in the wheel itself, the tire might be the problem if the tread is worn oddly. You can change that tire's position with another wheel and see if the noise changes to the tire's new location. Repeat by checking the other side.
If it's a All Wheel Drive then it could be a gear oil leak that has caused a bearing in the drive train to fail. Just adding gear oil won't fix the problem, but may limit the damage until it's repaired.
If it's a Front Wheel Drive, then you may have a Wheel Hub Bearing Assembly failing. This usually has a ABS [ Anti-Lock Brake ] light associated with it.
Either is dangerous and should be checked ASAP.
There are a number of possibilities here. First thing to do is make sure the new rear brakes are properly adjusted. If they are too loose they will not engage when you push gently on the pedal and the front brakes will be doing all the work. This could easily cause you to slide. There is a self-adjusting mechanism in the rear but these can become inoperative over time. The brakes can be adjusted manually.
Second, how much tread is on the front tires? As tread wears down the tire becomes less able to handle snow. Does one tire have less tread than the other? Tires have a wear bar built into them so look at the tread and see if you can find a rubber bar that extends across the tread. The more visible it is the less likely there is enough tread to handle snow. It may still be legal to use the tire but save it for summer. If the wear bar is almost flush with the tread,run your hand across it, then that is most likely your problem. Compare the front tires to the back ones, use a coin to see the difference, stick it in the tread groove and note where the tread comes on the coin. The grooves in the tread move snow away and once they are full the tires rides up on the snow instead of staying on the road. If you are unsure stop at a tire shop and get them to help check it out ( 3/32 inches is the minimum I think).
If these are good then you could have a brake caliper starting to go bad. They will seize up and stop working. When that happens the brake pressure transfers to the wheel that works. This will make the car pull to the side that works. So if the back brakes are good and the tires and good enough I would look at replacing the LEFT brake caliper. That would be the one sticking.
If you are travelling on roads that produce a noticable lean inside your car this could also be at least part of the problem. The car would tend to slide with the lean but if the roads appear flat then it's not likely the problem. Roads are "crowned" to be about 2% off level to help water run off but as a rule this shouldn't be the problem.
Hope this helps.
Don't waste your money on all season tires if you are going to be wading through deep snow. Get a good aggresive mud and snow tread for winter driving. I've had good luck with Goodyear's in Eastern Canadian winters. Hope this helps.
you either have a pulled belt in the tire or theres a separation in the tread belt and you need to have this checked soon as this tire could blow out at highway speed,if the noise is as bad as you say it is,jack up the van block the wheels and hand spin the tire and check and watch if it wobbles,has any flat spots,bulges wiggly tread in the tread face,just anything out of the ordinary
