After pulling TT for years I finally had my first blow-out coming home this past weekend, Before we left on the trip aired the tires to max pressure (65 LBS) and visually inspected them, the tires looked good, no cracks an the treads looked as good as new. we have a 2011 29RK North Country with dry weight at 7500 LBS, The Tires are the original tires from the factory ( Power King), I am looking to replace all 4 tires but I am not sure what brand of tire is the best, I don't really want to go back to the Power King. When my RV is at home it is stored under a shed and out of the sun and is parked on boards, off of the ground, It seems that with no more miles that I have on these tires they should last longer than these did. I a looking for information on what tires I should go with. Any help would e much appreciate. Thanks
