Gabriel® (Ride Control, LLC), the inventor and industry leader in automotive ride control technology, reminds their customers to change their shocks when installing new tires. The engineers at Gabriel HD are experts when it comes to heavy-duty ride control and they know what driving conditions can do to ride control systems and tires. They have released a video on the subject that can be viewed on The Original Gabriel.
This extra vibration is also transferred straight through the tires, which can then start to bounce and shake across the road as they roll. This causes unusual scuffing and wear patterns called “cupping”. Cupped tires cannot keep consistent traction with the road and can be unsafe to drive with.
Once cupping is noticed, tires should be replaced. Replacing shocks without replacing the tires will only slow the damage, not stop it. Once the tires are replaced the shocks should be replaced as well. Pairing new tires with old shocks will only ensure tire damage begins right away and will shorten the life of the tire. To ensure the longest possible tire lifetime and top driving performance, change your shocks when you change your tires.
