If your family hauler is a second-generation (2001-2007) Volvo XC70 AWD, you probably bought it for the safety it provides. Safety also requires focused driving and equipping your Volvo with the best tires for the conditions. Does tire choice makethatmuch of a difference? Yes, consider the difference in wet braking distance between the top tires and the fourth place tire observed in this Grand Touring All-Season comparison test.
Choosing the right tires for your Volvo XC70 can be tricky. Most second-generation Volvo XC70 vehicles came with the relatively obscure 215/65R16 size. If wet braking is important to you, and it should be, you may want to consider one of the top three tires referenced above (Bridgestone Turanza Serenity Plus, Continental PureContact with EcoPlus Technology, Michelin Primacy MXV4). The problem is that they're not made in your size, therefore you'll need to look at the 225/60R16 alternate size. 225/60R16 is about 1/2" wider, 3/10" smaller in diameter and fits the Original Equipment 7" wide rim without rubbing.
Now that you know what size to look at, what tire should you purchase? Obviously, if you live in a dry area like Phoenix, Arizona, you'll want to choose your tire based on variables such as dry braking and steering response. With these parameters in mind, I'd recommend choosing between the Bridgestone Turanza Serenity Plus, Michelin Primacy MXV4 and Michelin Pilot Sport A/S Plus.
225/60R16 Bridgestone Turanza Serenity Plus
225/60R16 Michelin Primacy MXV4
225/60R16 Michelin Pilot Sport A/S Plus
The Turanza Serenity Plus provides good wet grip, decent road manners and relatively long treadwear. Michelin's Primacy MXV4 shares theses traits, however the Serenity Plus offers a little more wet grip capability. Michelin Pilot Sport A/S Plus' strengths of crisp steering response and better dry grip make it appropriate for faster drivers.
