Hello, I’m also interested in this. On the door pillar, I see that the tire information plate simply reads, “235/45/R19 95V.” No mention of RFT. As long as they are the same size and have a 95V load rating or higher, fitting non-RFT is, in my opinion, absolutely okay. I’m sure you are aware of this as well. I would choose 99 XL additional load rated tires, which again have sidewalls that are firmer but not quite as stiff as the RFT.
For information, I believe that neither the A35 nor the A45 Mercedes have RFT tires installed at the factory. The Michelin Pilot Sport 4 strikes me as a wise option.
I’ll swap mine out for an AVON ZV7 because of the positive ratings and affordable rates.
Tire repair inquiries for the Infiniti QX30
It’s not a smart idea to drive with a flat tire.
A If you continue to drive on a flat tire, you risk damaging your wheel but your QX30 engine will still function.
You might be able to reach a repair location safely with the aid of a temporary sealant. However, short-term or emergency sealants run the risk of damaging TPMS sensors and, in some situations, voiding the tire warranty for Bridgestone or Firestone. Sealant might lengthen the repair process and increase labor costs if your tire needs considerable work.
The majority of extra tires are not built for distance or speed, despite the fact that this may sound fantastic in theory. Don’t utilize the little spare tire that most likely resides inside your 2018 Infiniti QX30 as a substitute for having your tire repaired. It is only designed to be used for a short period of time.
Locate your tire
Your Infiniti Qx30’s tires need to be carefully chosen, taking into account a number of aspects, including the type of car, its dimensions, and how the vehicle is used in relation to the routes that are driven on a daily basis. Pirelli has developed an extensive tire catalog for Infiniti that is intended to offer exceptional driving performance in all circumstances and complete safety to assist you in this critical research phase. You may choose from a wide range of high-performance tires for Infinitis in the huge Pirelli catalog, including winter, summer, and all-season tires made especially for city vehicles, SUVs, sedans, or sports cars. The Pirelli tires for the Infiniti Qx30 are the ideal combination of innovation and technology, with a unique tread compound that can easily handle any weather situation. The tire’s tread pattern is created to provide the greatest amount of straight-line and cornering grip while minimizing hydroplaning on slick roads, braking distances, and fuel consumption. You may confirm the technical details of each Infiniti Qx30 tire by going over the specifications sheet and contrasting the numerous available options. Once you’ve identified the Infiniti Qx30 tires that best suit your requirements, speak with a certified Pirelli store to learn more about the technical specifics and make your purchase with complete assurance.

Do Infiniti automobiles come with run-flat tires?
However, several modern luxury automobile makers, including BMW and Infiniti, have done away with the doughnut spare in favor of increased cargo room by utilizing run-flat tire technology. How does it function?
Can you use ordinary tires on an Infiniti Q50 instead of run-flat ones?
As long as they adhere to the manufacturer’s requirements, you can swap out four run-flat tires for four regular tires.
Remember that various tires are made to produce various outcomes. For a short distance following a puncture, a run-flat tire is intended to keep a car moving safely and steadily. RFTs can keep their shape and capabilities over a short distance without the use of air pressure.
A run-flat tire, as opposed to a conventional tire, features a thicker, more robust sidewall composed of unique heat-resistant rubber to withstand the weight of the car and its occupants for a short distance even when the tire has little to no air pressure.
When selecting conventional tires for a vehicle that originally had run flat tires, there are a few additional factors from the tire and vehicle manufacturers to take into account.
- Since the run flat tire is the answer, run flat vehicles often do not include equipment for emergency mobility. When switching from run flat tires to normal tires, drivers should be aware that their car might not come with a hand jack, spare tire, spare rim, or spare wheel.
- When run flats are replaced with regular tires, specifications like TPMS, alarms, and internal programming might be impacted.
- Pick conventional tires only if they satisfy your vehicle’s manufacturer’s specifications for size, speed rating, load capacity, and inflation pressure.
What cars are equipped with run-flat tires?
Run-flat tires are installed on vehicles at the factory by a wide range of luxury automakers. They are present in most BMW and Mini models. Run-flat tires are also standard equipment on Mercedes-Benz cars and SUVs. Audi, Cadillac, Lexus, and Infiniti are a few additional luxury companies that utilize them.
Are run-flat tires standard on all new cars?
Q. When I learned that my new car doesn’t have a spare tire, I was shocked. Was I defrauded?
Today’s new cars come with a compressor and sealant kit to temporarily replace a flat tire, but about one-third of them do not have a spare tire. A run-flat tire, which is made to function for a short distance after losing air from a conventional puncture, is available on some vehicles without a spare.
Because of regulatory pressure to get more miles per gallon of gasoline, automakers are omitting the spare tire: by removing the 40–50 pounds that a tire and jack typically add to a car’s weight, fuel economy is somewhat increased. (Incidentally, because automakers don’t have to pay for those parts, this enhances their profits.)
The issue is that if a tire’s sidewall is cut or if the flat is brought on by more severe damage than a tread rupture, a sealant kit won’t be of much assistance. Think about investing in a spare-tire kit, which comes with a tire, jack, and lug wrench, if you want to be ready for any kind of flat tire. These starter kits cost about $150.
Before you take delivery, “know how your automobile is outfitted,” advises Chris Jones, a licensed mechanic and tire specialist at CR. “Don’t assume the car has a spare tire if you’re going to purchase it. The showroom is the finest place to learn, where you can also utilize it as a talking point, rather than on the side of the road after a flat tire.”
I’m from New England and have driven anything from a Segway to an aircraft carrier. I have collectively operated tens of thousands of vehicles, many of them on international racetracks. At the CR Auto Test Center today, such knowledge and enthusiasm are being used to empower customers. And if that means sacrificing some tires in the name of the truth, then be it. Continue with me
How are run-flat tires identified?
Run-flat tires allow you to drive for a short distance while they are “flat” after being punctured, giving you time to get to a technician. Depending on the tire’s manufacturer and the weight of the automobile at the time of the puncture, run-flat tires can go a certain distance and travel at a certain speed. Typically, you can determine if your tires are run-flat by looking at them or by looking at other aspects of your car.
On your tires, look for the terms “Run Flat,” “SSR,” “HSR,” “RF,” “Run On Flat,” “ZP,” “DSST,” and “RFT.” To make it simpler for the car owner, some tire manufacturers who produce run-flat tires simply label the tire as such. The terminology used to describe these tires varies between brands, as can be seen in the examples below:
- PIRELLI: Simply look for the phrase “Run Flat” on the tire’s side, which is typically located amid other manufacturer information and identification numbers.
- Continent: On the side of your tire, typically close to other manufacturer information and numbers, look for the words “SSR.”
- HANKOOK: On the side of your tire, typically next to other manufacturer information and numbers, look for the letters “HSR.”
- YOKOHAMA: On the side of your tire, typically next to other manufacturer information and numbers, look for the letters “RF.”
- GOODYEAR: On the side of your tire, typically close to other manufacturer information and numbers, look for the phrase “Run On Flat.”
- MICHELIN: On the side of your tire, typically among other manufacturer data and numbers, look for the letters “ZP” or “ZPS.”
- DUNLOP: On the side of your tire, typically among other manufacturer information and numbers, look for the words “DSST.”
If you notice one of these codes on your tires—RFT, SSR, or DSST—all three stand for RUN FLAT TIRES. Run-flat tires are occasionally identified on Bridgestone tires by the code RFT (Run Flat Tire). Dunlop occasionally uses DSST, while Continental uses the designation SSR (Self Supporting Run flat).
- On the sides of your tires, near the other numbers and manufacturer information, search for these codes.
If you notice one of these codes on your tires—ROF, EMT, or ZP—they pertain to particular manufacturers. On their run-flat tires, several tire manufacturers, notably Goodyear, Bridgestone, and Dunlop, utilize the code ROF (Run On Flat). Run-flat tires from Goodyear are also referred to as EMT (Extended Mobility Technology) tires. Some manufacturers, including Michelin and Yokohama, use ZP or ZPS (Zero Pressure or Zero Pressure System) on their run-flat tires.
- On the sides of your tires, next to the manufacturer information, look for any of these codes.
Can run-flat and non-run-flat tires be used together?
- Never mix run flat tires with normal tires (tires without run flat technology), unless necessary in an emergency and only temporarily. As quickly as possible, a run-flat tire should take the place of the regular tire.
- Combining various run flat technologies or goods is also not advised.
How can I tell if the tires on my car are run-flat?
Checking the tire marks on each of your tires is the next simplest method. Run-flat tires will be identified with one of these codes, depending on the brand:
- ROF: Companies including Goodyear, Bridgestone, and Dunlop utilize this marking. Its acronym is Run on Flat.
- EMT: This trademark, which stands for Extended Mobility Technology, is also utilized by Goodyear.
They all essentially mean the same thing: that, if you drive under 50 mph, your punctured tires can still be used for up to 50 miles. This is important because, if the punctured tire warms up (as they tend to do at greater speeds), it could lead to more serious splitting and necessitate the assistance of an emergency repair professional.
Because there is no way to tell if this speed or distance limit has been exceeded, auto repair professionals may refuse to fix run-flat tires as a result of the speed limit on punctured run-flat tires. A run-flat tire that has been repaired after exceeding this limit is likely to still be structurally unsound, which might lead to considerably more dangerous damage down the road.
What drawbacks do run-flat tires have?
Run-flat tires won’t abandon you by the side of the road or need you to change a tire by digging out your spare. However, they have some drawbacks, such as the cost of replacing run-flat tires and the possibility that a catastrophic tire failure might render your vehicle immobile without a spare.
