Tires
I'm basically in the same situation as you, my wife is the primary driver. I have the Bridgestone Deuler A/T Revos on my 99 LC, and they are the best. They have the best all around traction rating, and are reasonably quiet. My wife loves them, and she doesn't hear any difference between them and the Dunlop Grand Tecs OEM tires. I also like the Goodyear Fortera, they are probably a little quitier, but you can't beat the all around traction of the Revos. I live in Michgan, and always buy tires from tirerack.com. They are about 30 minutes away, have a huge selection, ratings, and reviews. Very informative site!!
