Bridgestone has been the industry leader in tires that can provide you with longer mobility at no pressure ever since it created the run-flat tires for the revered Porsche 959. Now that most sports cars come equipped with all-wheel drive, the Porsche 959 revolutionized the supercar industry.
However, despite the fact that more automakers now utilize run-flat tires, they have yet to win over non-OEM customers. There are a number factors that contribute to this, but the main ones are their astronomical cost, significantly uncomfortable ride, and shorter treadlife than equivalent normal tires.
Through the years, the Japanese tire manufacturer kept inventing and released more advanced run-flat tires. The company’s most well-known design is the DriveGuard, the first run-flat tire that combine a comfortable ride with zero-pressure maneuverability.
Bridgestone, however, didn’t sit on its laurels and introduced the enhanced DriveGuard Plus in 2022. The updated model has several enhancements, including increased comfort, longer treadlife, and greater wet/snow grip. Bridgestone claims as much, at least.
However, the Bridgestone DriveGuard Plus is still pricey. For instance, depending on the retailer, the Turanza QuietTrack ordinary grand-touring all-season tire from Bridgestone costs around $180. When compared to the DriveGuard Plus, which costs around $220, the convenience of running on run-flat tires will cost you more than $150. If you choose larger sizes, the difference will be significantly greater, however to be fair, the DriveGuard Plus often has higher speed ratings.
Should you choose the Bridgestone DriveGuard Plus or is there another run-flat tire that belongs on your car if you finally want to get rid of the spare tire (or tire repair kit) and enjoy peace of mind on longer trips? That’s precisely what I’ll show in my thorough DriveGuard Plus review, in which I contrast it not just with its top run-flat competitors but also with common grand-touring all-season tires.
What are the features of the Bridgestone DriveGuard Plus?
Bridgestone’s NanoPro-Tech (Nanostructure-Oriented Properties Control Technology) rubber compound, used to make the tire, was developed through molecular design to enhance the bonding between the molecules of rubber and silica. As a result, the compound loses silica’s great wet grip while becoming hydrophobic (silica is hydrophilic). The Bridgestone tires are routinely supplied with the greatest treadwear guarantees in their respective categories, which increases wear life.
But how did Bridgestone achieve the DriveGuard Plus’ claimed level of comfort? The business won’t say, but I assume it’s because of its dedication to its run-flat tires and ongoing development of the idea. Bridgestone is one of the few firms that tweaks the recipe to consistently enhance its run-flat tires, and this should be evident in how well they perform on the road.
What are the Bridgestone DriveGuard Plus’ maintenance indicators?
The Bridgestone DriveGuard Plus has the industry-required tread wear bars, which may alert the driver when the tread hits the lowest allowable tread depth in the majority of countries across the world—2/32 inches.
Bridgestone does not provide wear indicators that may reveal the tread depth in more detail, in contrast to its rivals Continental. This is significant because, for acceptable snow traction, the wintertime required minimum tread depth is 5/32 inches.
And it’s important to keep track of tread depth for road safety. It’s not uncommon to see tires with nearly little tread still on them or to see worn tires being utilized in icy weather. Sadly, using a tread depth gauge is your only choice when using the DriveGuard Plus. Although it’s a cheap item that doesn’t belong in your automobile, few people really use it.
What is the Bridgestone DriveGuard Plus warranty?
How does the Bridgestone DriveGuard Plus behave on dry roads?
However, more crucially, the steering is linear, accurate, and returns detailed information about the route. Certainly not at the level of performance tires, but excellent for the class. On newer automobiles with incredibly light electronic steering, you probably won’t even notice that the steering seems heavier to some people.
You’ll be taken aback by the traction as well. You and your family will be safe since the DriveGuard Plus will drive and stop just like a standard grand touring all-season tire. But even more striking is the lateral grip. The DriveGuard Plus nevertheless offers some of the greatest Gs in the corners in the class, even if they are not as good as the grand-touring all-season tires that are at the top of their class.
Overall, the DriveGuard Plus destroys its run-flat rivals while not exactly setting new benchmarks for grand touring all-season tires. This is hardly shocking as Bridgestone immediately improved the original DriveGuard, an excellent tire, before introducing its run-flat option.
How is the Bridgestone DriveGuard Plus on wet and slippery roads?
Furthermore, the DriveGuard Plus needs to be pushed hard in order to reach its limitations because the lateral grip approaches the industry-leading non-run-flat tires. Although stopping distances are a little bit longer than they would be on conventional tires, they are still highly competitive, and the longitudinal traction is also quite strong.
When pushed over 90%, the DriveGuard Plus is less effective. It becomes more difficult for the driver to maneuver the vehicle into a turn when the handling balance shifts to oversteer at that point. Fortunately, unless you drive like a crazy, this is probably not going to happen to you on a public road.
However, the current crop of normal grand-touring all-season tires, such as the Bridgestone Turanza QuietTrack, Continental PureContact LS, and Goodyear Assurance ComfortDrive, will perform better at the limit.
It has good resistance to hydroplaning. The many sipes and broad, deep grooves significantly reduce hydroplaning. As a consequence, even if your car strikes a large water puddle, it will still stay stable.
With that being said, how is the Bridgestone DriveGuard Plus on snowy roads?
The DriveGuard Plus isn’t very outstanding in the corners, though. Although reliable, the lateral grip is not very strong. More significantly, the tire has significant understeer at the limit, which makes cornering challenging. By just depressing the gas pedal and waiting for the weight to shift to the front wheels, you may accomplish that goal, but you’ll lose speed.
Furthermore, don’t count on having great traction on the ice. Although the DriveGuard Plus outperforms some less expensive grand-touring all-season tires in terms of performance, you should still be cautious and slow down when driving on ice roads.
Overall, the DriveGuard Plus performs better than other grand-touring all-season tires and isn’t by any means a horrible winter performer. However, tires with higher traction and better handling, such as the Michelin CrossClimate 2, Continental PureContact LS, and Bridgestone’s own WeatherPeak all-season/all-weather tire. They do not, however, have run-flat capabilities, it is fair to assume.
Is the Bridgestone DriveGuard Plus suitable for off-road driving?
No, driving over rough terrain is not recommended with the Bridgestone DriveGuard Plus. It is an all-season grand touring tire that is solely intended for paved roads and the rare dirt or gravel route.
Long-term use of the DriveGuard Plus’s tread might harm the surface because of uneven and abrasive surfaces. Even more significant problems like tread separation, cuts, and bulges may result from it.
The Dueler A/T Revo 3 all-terrain tire from Bridgestone is made to be driven on both paved and unpaved routes.
Is the Bridgestone DriveGuard Plus a run-flat tire?
A run-flat tire, the Bridgestone DriveGuard Plus is. This tire, unlike the majority of its competitors, was created from the ground up with run-flat characteristics and is not based on any other Bridgestone goods. The DriveGuard Plus, like every other run-flat tire, has a maximum range of 50 miles (80 km) and a top speed of 50 mph (80 km/h) at zero pressure. Drivers will find this to be incredibly convenient because they won’t need to fiddle with a spare tire or a repair kit. In addition, it makes room in your trunk.
However, there are several drawbacks to run-flat tires that you should think about before purchasing. To begin with, run-flat tires weigh 5–10 pounds (2–5 kg) more than standard tires. Although it may seem little, this weight is unsprung, meaning that the suspension system is not supporting it. A vehicle’s handling may be impacted by more unsprung weight, but it will also be more difficult for the suspension to respond to wheel movement, such as when striking a pothole.
However, the additional rotating mass also hinders the engine’s ability to accelerate, resulting in somewhat reduced performance and increased fuel usage. Although removing the spare tire and wheel repair kit might help, the rotating mass is typically worse than hauling baggage.
How are the Bridgestone DriveGuard Plus’ road noise and comfort performance?
The DriveGuard Plus, however, is a run-flat tire that can compete with ordinary tires in terms of ride comfort. The smoothest run-flat tire was its predecessor, but this model ups the ante. Now, on most roads, the DriveGuard Plus rides as smoothly as a set of conventional grand touring all-season tires. Driving on the highway is as smooth as it gets since the tires handle minor road irregularities quite well and don’t shake the cabin at all.
Larger and sharper undulations certainly make the ride a little more choppy than, say, the Turanza QuietTrack, but I’ve also driven on worse conventional tires that made louder noises while driving over potholes. Most people, I believe, would not notice the difference if they did not sample two sets of tires side by side.
Also not a problem is noise. At greater speeds, if you listen carefully, you can hear a high-pitched noise, but by then the wind noise has probably drowned it out. Again, the DriveGuard Plus is very quiet and smooth at high speeds for a run-flat tire.
I’m happy that Bridgestone finally made run-flat tires affordable for automobile owners whose vehicles were originally equipped with standard tires. Your automobile will be as comfy as before with the DriveGuard Plus, and you’ll never have to stress about replacing a tire in the middle of nowhere.
Drivers of high-end vehicles who already have run-flat grand touring tires from the factory should anticipate a significant improvement in comfort with the DriveGuard Plus at practically no performance cost.
Should I buy the Bridgestone DriveGuard Plus?
Yes, the Bridgestone DriveGuard Plus is now the best option available if you’re looking for a grand touring all-season tire with run-flat capability. The newest run-flat tire from Bridgestone is the first run-flat tire to provide reliable dry, wet, and snow grip while also riding smoothly over bumps.
Not to mention, the DriveGuard Plus has the longest treadwear warranty in its class, which guarantees a lengthy treadlife in a department where other run-flat tires fall far short. You’ve got a winner on your hands when you factor in the peace of mind that comes with driving over lengthy distances.
What sizes does the Bridgestone DriveGuard Plus come in?
There are 34 sizes of the Bridgestone DriveGuard Plus, with wheel diameters ranging from 16 inches to 20 inches. Bridgestone offers sizes for minivans, crossovers, certain SUVs, and small and midsize vehicles.
