I have HK sneakers on my E450/24'. It's the first time I'm running HK's, previously I ran Coopers and Michelins on my 7 pickups for about 5000k miles with no issues.
I plan to keep a close eye on these tires as the miles accumulate.
When the time comes to part ways, I will look into a Michelin tire using the Michelin Advantage Program and compare that offer to what Cooper is offering at that time.
Tire prices fluctuate , the deals change over time and the price gap between brands increases and decreases. You have to price them and compare the deal at the time of purchase.
