Couple of things to check... First, make absolutely certain that the lug nuts are tight. Perhaps they didn't get the lug nuts torqued up.
Second, have the tires balanced. If both of those dont help then it is a possibility that one of the tires is defective.
Ans 2. Wrenchdude knows what he is talking about; every single thing he says above is correct. Are you frightened by what he wrote ? You should be. It seems rather likely that the wheels were not balanced. Whenever you change the tires on the front wheels you must have them balanced; if you didn't you should do it now.
If you ordered and paid for balancing you can easily check. Look at the front wheels just where the tires meet the rims. You should see a small, shiny lead weight clipped to the rim. If you don't see any then the wheel wasn't balanced. If you do see them then you still need to check.
Drive along a good straight road in light traffic (better still no traffic). Slowly increase speed from 30mph to 70mph, holding the wheel lightly. If you have unbalanced wheels on the front, the car will start to shake/judder at a particular speed (50mph is common), and you will feel a bit of shaking on the steering wheel. You slow down, it goes away; speed up, it comes back.
The fact that you have fitted winter tires indicates that you probably have snow and ice where you live. Do the above test on a well plowed and sanded road, but do it. If you get a shake while on a slick road you could lose control.
Tires are made for the conditions that they are driven in. Therefore if you live in an area that has cold winters, that is it snows for a large portion of the winter, you probably should purchase winter tires. If you are living in Florida for example winter tires would not be required and year round tires would be sufficient.
No,but tires out of balance will cause this. Have them balanced and rotated.
Try having your tires balanced and rotated. I used to have a car that would shake very bad when applying the brakes and I did everything you did. Then a guy told me to have my tires balanced and rotated and it fixed it until the tires became unbalanced again.
Winter tires are for use predominately in the snow and All-season tires are exactly that meant to be used all year around. You will not get as good a traction on snow with the All-season tires as you would with the winter ones but the decision comes down to what part of the country you are in and how much snow you get.
check your tires for broken belt++ out of round
Shocks and other suspension components (A-frame bushings, etc.) deserve a close inspection, and all connections (tie rods, etc.) should be checked.
To make it easier to switch to them and back to regular tires. Also, to avoid the cost of having the tires dismounted and remounted.
It needs an front end alinement or your tires & wheels need rotated
You wont hear much of a sound, but more of a vibration at certain speeds. I recently installed a set of tires on my truck and because of an inbalance, around 70mph the truck would start to shake. Once I had it corrected it was smooth sailing.
Most of the time this is caused by a tire out of balance or a bent wheel. Take your car to anyplace that sells tires and have the tires rotated and balanced.
Water is way too heavy to put in tires, plus in the winter it will settle and freeze so your tires will be off balance. Also about the winter part, if you completely filled your tires with water and let the water freeze, the tires would explode, since water expands when it freezes.
7 degrees Celsius, or 45 degrees Fahrenheit, as per Volvo tests. Above 7C, all-season & summer tires get better the warmer it is. Below 7C, winter tires get better the colder it is.
