Have driven a set 295/70X17 and loved them. Like others have said you need to air them up to minimize sidewall flex. I ran them 65psi in the front and 55 psi in the rear and rotated about every 5-7000 miles. I got a good 40,000 miles on that set. Just yesterday, I changed out to a new set 305/65/17 which is a little smaller but wider a 12" . They look small, however, the tread pattern is wider, and the profile is a little shorter. Because of this, the sidewall doesn't flex and I'm running these @ 60 psi front and 50 psi and the ride has improved greatly. For the money, you can't beat the performance. Quiet, good ride, good wear etc. Only problem, not very good in slush at freeway speeds in winter.
