Maintain correct tire pressure.
 Drive smoothly:  avoid fast  starts, hard braking and  tire screeching.
 Tire wear  increases with speed.
 Correct front  wheel alignment is very important.
 Unbalanced wheels impair tire economy and  driving comfort.
 If the wheels are rotated, they should be  kept on the same side of the car so that they revolve in the same direction
as prior  to rotation.
 Hitting curbs or potholes can damage the tires and/or wheels permanently. 
Flat spots 
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a  tendency to distort
slightly,  forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however,  disappear when the tire warms up. The degree to which  the flat spots form  depends on the type of
cord used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and  consequently longer
for the flat spot to disappear. 
CAUTION:  The car must  not be  driven with wheels of different  dimensions. The use of different  size wheels can
seriously damage your car's transmission.

Snow  chains
 
Snow tire chains can be  used on your Volvo with the following restrictions:
Snow chains should be  installed on front  wheels only. Use only Volvo approved snow chains.
Snow chains may be  mounted on tire dimension 195/65R15.  Tire dimension 205/55R16  requires a  special type of
snow chain. Consult your Volvo retailer. Snow chains may not be  used on 205/55R16  tires. 
If accessory,  aftermarket or "custom" tires and  wheels are installed and  are of a  size different  than the original tires
and  wheels, chains in some cases CANNOT be  used. Snow chains cannot be  used on those turbo-charged models fitted
with all-season tires 225/50R16  or 225/45R17  or 225/40R18.  Sufficient  clearances between chains and  brakes,
suspension and  body components must  be  maintained.
Some strap -on type chains will interfere  with brake components and  therefore CANNOT be  used. 
Consult your Volvo retailer for additional snow chain information. 
CAUTION:
 Check local  regulations  regarding the use of snow chains before installing.
 Always follow the chains manufacturer's installation  instructions carefully. Install chains as tightly as possible and
re-tighten periodically.
 Never  exceed the chain manufacture's  specified maximum speed limit. (Under no circumstances should that limit
be  higher than 30 mph (45 km/h).
 Avoid bumps, holes or sharp turns when driving with snow chains.
 The handling of the vehicle can be  adversely affected when driving with chains. Avoid fast  or sharp turns as well
as locked wheel braking.

Tires for winter use: 
Owners who live in or  regularly  commute  through  areas with sustained  periods of snow or  icy driving
conditions are strongly advised to fit  suitable winter tires to help retain the highest degree of traction.  
It is important to install  winter tires on all four wheels  to help retain traction during cornering, braking and
accelerating. Failure to do so could reduce traction to an  unsafe level  or adversely affect handling. Do not mix tires of
