If you are sticking to the pavement and don't need snow/ice/off road capability, the cheapest highway tread tire is probably your best bet. Big knobby tires that give good traction also tend to be noisy on the pavement.
At ~6,000miles/yr lightly loaded, your tires are likely to age-out before they wear-out unless you have an alignment or suspension problem that eats up the tires, no real benefit to .
Sure check the load index to make sure it's reasonable but as GitDog said, in that size, they are almost all intended for trucks.
