Cooper Discoverer Rugged Trek 265/50R20 111T MPN 171110005

Name: Cooper Discoverer Rugged Trek 265/50R20 111T MPN 171110005
Brand: Cooper
SKU: ST-171110005

Between the Cooper Discoverer Rugged Trek 265/50R20 111T MPN 171110005 and the nearest wheel & tire clearance options, what makes the call?

Cooper Discoverer Rugged Trek 265/50R20 111T MPN 171110005 is recorded as an exact MPN row, so shoppers can compare one tire size instead of a broad family label.

Put it next to the Bridgestone Dueler A/T Ascent 265/60R18 110T MPN 009706 and the Firestone Destination A/T2 245/75R17 112S MPN 013915 and the Cooper Discoverer Rugged Trek 265/50R20 111T MPN 171110005 leads for one kind of buyer while giving ground elsewhere. None of the three is the automatic answer, so read the package, fitment, and install rows before you read the price.
