Although there has been Hankook tire failures on the PW Excel, saying a "high number" is a bit if a stretch, particularly considering the number of units on the road. No matter which tire brand you select, the Excel is heavy in the rear so the tire will be loaded close to its maximum rating (unless you do some modifications to use tires with a higher load rating). This situation can get worse if the load is not properly distributed or if one adds a load to the rear (such as a cargo box). Proper prevention includes getting a measurement of the weight on each tire with the van fully loaded for travel to make sure they are within their rating, keeping the required pressure (80 psi cold in the rear) and regular visual inspection.
If you make the switch to a different tire, please keep us posted on its performance.
