x4 for Bridgestone Duravis 250's. Like one poster mentioned. Pay particular attention to the spacing between the front and rear tires. If the spacing is rather close and you're running GY Marathons like I was, you'll want to find a tire that will have the same overall diameter of the Marathons. A GY Marathon ST235/80/16 E is 30.7 Inches in diameter and the Bridgestone Duravis R250 is 30.7 Inches in diameter. I chose to go with the Bridgestone 245/75R16. The Duravis is slightly wider in this size, but most RV's have enough fender well room to accommodate that small difference. I had so many problems with Marathon belt separations through the years that I don't care to repeat. Since I switched, I have never looked back, literally. Here are some tire specs between the above mentioned tires.
