Low-end choices from Sears (using up a store credit) in P225/75R15 are

Dunlop # 57570 Radial Rover A/T
Bridgestone # 24455 DUELER APT III
Goodyear # 87276 Wrangler RT/S

All are rated:
A Traction
B Temperature (In Oregon's Willamette Valley, not an issue)
S Speed

Treadwear ratings do differ:

500 Dunlop
400 Bridgestone
340 Goodyear

Will be selling the vehicle within a month, so my priorities are
a) maximizing resale
b) a good deal for the buyer

Any comments on these tires?

Thank you.
