I have the G670s on my 2006 Revolution now. I had the front tire blowout at 28,100 miles. Almost lost control of RV. Just missed going off bridge by two feet. The tires are 7 years old. I keep the tires covered, check air pressure and under weight limits. I could just replace the other 5 tires with Goodyear or go with new set of the xze2s. Which tire would you pick?
