If your new tires are riding rough or bumpy, there could be a few reasons for this. The first thing to check is tire pressure. The rough ride could be due to under-inflated tires. Another cause could be an alignment issue.
Rough, bumpy rides can be due to bad tire alignment, incorrect air pressure – too low, too high, different pressures in each tire – or even the tires not being mounted properly. Worst case scenario could be the rims themselves have become damaged or warped.
In general, it can take around 500 miles to fully break in a new set of tires until it will offer optimal performance, so we recommend accelerating a little easier, avoiding hard braking and taking turns a little slower than usual.
Your new tires may feel different
Tires with a deeper tread tend to flex or “squirm” a bit more -- so they may feel slightly less responsive than your old tires, even if you replaced your old set with the exact same brand and model.
New tires with deeper functioning treads and designs are great for long trips because they provide the driver with a smoother ride. Also, new tires are less noisy when compared to worn out tires. Both of these factors are huge for those who have a long morning commute or frequently take long highway trips.
Avoid bigger wheels if you want a smoother ride.
As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car.
If you are suddenly feeling every bump in the road and your car, truck, or utility vehicle keeps bouncing after you have driven over the bump, Willoughby Hills Auto Repair advises that it's time for new struts and shocks. A bouncing car is one that has worn struts and shocks on the front and back wheels.
According to Will Robbins, director of consumer product strategy for Bridgestone Americas, these vent spews are a result of the tire manufacturing process and happen as the tread pattern mold is pressed into a new tire.
A bumpy ride can be caused by a tire that has insufficient air, improperly aligned wheels; or even by tires that have rocks or debris stuck in them. These issues are all pretty simple fixes, so hopefully one of them will explain your bumpy ride problems.
Even if your new tyres are the same model as your old tyres, you will notice a significant difference whilst driving, especially if your old tyres were particularly worn.
It's likely your old tires had very little tread depth by the time you replaced them. Tires with very little tread tend to respond quicker, because there's less tread that needs to flex during maneuvering. So, new ones might feel slightly less responsive before they're fully broken in.
By driving on the tires for a few hundred miles, these lubricants will wear off and allow the tire components to begin working together. Not until the tread is slightly roughened will you be able to feel a tires true gripping power. It's also important to note that tires with low tread depth respond more quickly.
You may have a little bit less traction for the first couple of miles, but if you aren't trying to race, it shouldn't be an issue. Short answer: Nothing. Longer answer: There's a belief among some people that you need to drive a certain way on new tires due to a bit of the mold release compound still being on them.
While your car is engineered to tolerate some movement, an increase in bumpiness or shaking while driving is an indication struts and shocks are worn-out. When struts or shocks are damaged or worn-out, the tires lose contact with the road and produce a bumpy and unpleasant car ride.
The common symptoms of an out-of-balance wheel-tire assembly are uneven and faster tread wear, poor fuel economy, or vibration in the steering wheel and/or floorboard that gets worse at faster speeds. When all areas of the wheel-tire assembly are as equal in weight as possible, the tire will roll smoothly.
Wheel and tire problems
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
You'll Get a Rough Ride
Some cars are made to have a smooth ride, like floating on a cloud. You'll feel every bump in the road with overinflated tires. Tires with the proper air pressure can absorb the shock of potholes and bumps in the road.
Overinflating tires makes them more stiff and inflexible. When you encounter anything on the road, like potholes, curbs, or debris, you have a higher chance of getting tire damage because of it. They'll also make your vehicle's ride much more uncomfortable – you're sure to feel every bump in the road.
You are going to need to buy new tires. Does my warranty cover my sidewall bubble problem? If the bubble is the result of a manufacturing defect, your manufacturer warranty should indeed cover the replacement or a pro-rated replacement of your bad tire. However, don't count on the bubble being the manufacturer's fault.
You should rotate your tires as recommended by the vehicle manufacturer, or every 5,000 miles. For many of you, that will mean when you get your vehicle's oil changed.
Suspension Warning Signs
Some common signs that your suspension system needs a little TLC are: Continued bouncing after hitting bumps or a dipping when braking. A drifting or pulling to one side when turning corners. One side of the parked car sitting lower than the other side.
Larger tires will typically give you better handling and stability, while smaller tires will provide you with improved ride quality and a smoother ride at the expense of some handling.
A monotube shock features a wider piston in a larger tube, while a twin-tube has a smaller piston in a smaller tube with a secondary tube filled with hydraulic fluid surrounding it. The advantage of a twin-tube design is that it creates a softer ride as it's a low-pressure system.
