Sim como eu, aliás no caso da marca Volvo, eles enviaram um boletim informativo para toda a rede Volvo:Eu prefiro pneus sempre bons nos 2 eixos... []

Tire Rotation
As suspensions and drive trains evolve, so do vehicle manufacturer recommendations for tire rotation.
Volvo's recommendations have always had a technical basis, while leaving some latitude for customer
preference.Presently, for current models, Volvo has no recommended tire rotation. Because this represents an evolutionary policy, customers may need the guidance of a Volvo service advisor to help them understand the performance and handling tradeoffs that come with tire rotation.
Benefit of Tire Rotation
On a front-wheel drive car, the demands placed on the front wheels during acceleration and cornering
can mean a dramatic difference between front and rear tire tread wear. Without periodic tire rotation
front-to-rear, the front tires will typically require replacement sooner. The primary perceived benefit of tire rotation is that front and rear tires will wear down at about the same average rate. In absolute
terms, four tires will not last any longer this way. It becomes a customer choice between replacing two tires sooner and replacing all four tires later. However, with all current Volvo models, Volvo believes that numerous technical, performance, and handling benefits outweigh any perceived benefit of tire rotation. Following are some of those benefits.
Benefits of Not Rotating Tires
Braking Stability Performance
During hard braking, braking on a slippery road, or braking in a curve, good rear tire tread may help you avoid oversteer. Oversteer is when a turning vehicle wants to keep turning because of momentum and dynamic forces on the vehicle suspension. Volvo stability systems are all designed toward reducing or helping a driver avoid oversteer. Still, all things being equal, having more rear tire tread can contribute to reduced oversteer. Without rotation, the rear tires will naturally wear more slowly and have more tread.
Tread Set
As tires age, the tread adopts an angular set, based on its angle to the road surface. For vehicle
handling reasons, front and rear tread angle is not the same. If tires are rotated, the tread will
eventually set at an angle somewhere between what is optimal for a front or rear tire. Although vehicle ride, handling, and road noise may still be acceptable, they may not be optimal. Additionally, an infrequently or irregularly rotated tire may result in tire noise, faster tire wear, and unpleasant changes in steering feel and vehicle handling.
Driving Performance
A tire that can fully adapt to its position will generally provide better steering feel, lower tire noise, and better fuel economy.
Suspension Wear Diagnostics
Every vehicle's suspension needs periodic inspection and maintenance. A tire's tread wear pattern
can be an aid in detecting and diagnosing a suspension problem. Each tire, if left in place, tells a story
about its place in the suspension. Tire rotation, on the other hand, can mask a developing problem.
Early detection is very important, because suspension problem can worsen tire wear, and reduce
vehicle performance, handling, stability, and fuel economy.
