If there is one single thing about tires that seems to unite consumers almost unanimously, is people's dislike of the ride quality of run-flat tires. Surely, the technology has its advantages, like the ability to drive the vehicle to safety up to 50 miles at 55 mph. In addition, some vehicles don't come from factory with a spare tire, which makes a run-flat tire almost indispensable. The trade-off, however, is the stiffness of the ride. Early versions of run-flats were extremely loud and rigid and transferred every bump and imperfection on the road to the steering wheel. And while there have been great advances in the technology, there are those who still prefer the smooth riding of a standard tire over the often stiff ride provided by run-flats despite the advantages.
That is, until Bridgestone released the DriveGuard. The DriveGuard is Bridgestone's Grand Touring All-Season self-supporting replacement run-flat tire designed for safety-minded drivers whose cars were not originally available with run-flat tires, as well as drivers looking for a longer wearing, better riding option to replace their vehicle's Original Equipment run-flat tires. The word 'revolutionary' is thrown around quite a bit these days, but the DriveGuard is exactly that: a run-flat Grand Touring All-Season tire that drives like a standard tire. Finally! No more trading off technology for a smooth ride!
On the test we performed last year pitting the DriveGuard against the very comfortable Michelin Primacy MXV4 standard, non-run-flat tire, we came out with the impression that the ride quality on both tires is almost the same. At first, the rigidity of the DriveGuard was a little more pronounced, especially on expansion joints on the highway. After a while, that modest increase in firmness became virtually unnoticeable. And that's great news for drivers who would like to have the peace of mind of a run-flat, but don't necessarily like to trade-off comfort to achieve that.
In addition, the DriveGuard is the first run-flat tire recommended for vehicles that did not come O.E. with run-flats. Keep in mind that when a car comes with run-flats, the suspension (among other things) has been engineered with run-flat tires in mind. Now, with the DriveGuard, you can enjoy the extended mobility features of a run-flat even if your car didn't come originally with those types of tires.
Go ahead and give it a try and see if the Bridgestone DriveGuard is available for your vehicle.
