Tips for Improving Driving Comfort: How to Avoid a Harsh Ride
As spring potholes begin to rattle drivers and every small crack in the road translates into back pain, it’s essential to recognize that ride comfort is not solely a matter of road quality but also a reflection of our vehicle maintenance choices.

Ride smoothness is a delicate balance, and often we inadvertently turn our cars into stiff rides by trying to follow trends or ignoring the warning signs from our vehicles. In reality, restoring the suspension's ability to absorb bumps quietly can be achieved without significant investment, provided we understand where engineering calculations end and our operational mistakes begin.
The first and most significant factor that drastically changes the road feel is tire selection. Many fall into the marketing trap of buying tires with high-speed ratings or labeled as 'high-performance.' These tires have extremely stiff sidewalls, allowing the vehicle to handle better in sharp turns at high speeds. However, for everyday comfortable driving, this is the worst option.
It is much wiser to consider touring models (touring tires). They have a softer compound and a higher profile, allowing the tire to act as the first stage of shock absorption, soaking up small vibrations before they reach the suspension arms. Additionally, one should not forget about tire pressure: over-inflated tires by 0.2 atmospheres can turn a vehicle into a rigid machine, making regular pressure checks the cheapest way to enhance ride smoothness.
The next step is to critically examine the wheels. Today, there is a trend towards large diameters with low-profile tires. While this may look stylish, in terms of comfort, you are essentially driving on a 'strip of insulation' wrapped around metal. The larger the wheel, the less rubber remains to cushion impacts.
If the braking system design allows, switching to smaller diameter wheels with a higher profile tire provides a much more noticeable effect than replacing expensive struts. You gain a larger air cushion that protects both your wheels from bending and your suspension from destructive loads.
The condition of the shock absorbers and struts determines how quickly the body settles after encountering uneven surfaces. The problem is that these components wear out extremely slowly, and drivers gradually acclimate to the declining performance. Signs that the hydraulics can no longer cope include not only oil leaks on the casing but also excessive body roll after stopping or uneven tire wear. During inspections, be sure to check the silent blocks and bushings. These rubber-metal joints are the primary fighters against vibration. When the rubber inside dries out or cracks, the suspension loses its integrity, and you start hearing metallic 'clunks' where silence once prevailed.
It is also important to mention ground clearance. Over time, springs fatigue and sag, disrupting the entire geometry of the control arms. If the vehicle visually appears 'lowered' or frequently hits the ground protection on familiar bumps, merely replacing the shock absorbers will not remedy the situation. New springs are needed to return the body to its calculated position. Additionally, exercise extreme caution with tuning that involves lowering the body by cutting spring coils. This is a guaranteed way to ruin the suspension, as the compression stroke of the shock absorber shortens, causing it to operate in non-standard modes with constant 'metal-to-metal' contact.
For owners of premium models with air suspension, the primary focus should be on the seals of the air springs and the compressor's operation. The slightest air leak forces the pump to run continuously, leading to overheating and costly repairs.
