More and more brand-new BMW cars leave the factory with run-flat tires installed. Others prefer conventional tires, despite the fact that many owners appreciate the piece of mind that comes with tires that can extend your driving distance by 50 to 100 miles when flat. So, if a BMW arrived with run-flat tires, can it be used with ordinary tires?
You can use ordinary tires on your run-flat equipped BMW, if you’re searching for a quick and simple solution to that query. Both standard tires and run-flat tires have advantages and disadvantages, and we want to assist you in making the choice that best meets your requirements. One word of caution, though: due to the handling and performance variations between the two tire types, if you’re thinking about switching the run-flat tires on your BMW to standard tires, you must do so on all four of them.
Why should a BMW move from run-flat tires to conventional tires? New BMWs no longer come with spare tires in order to minimize overall weight. Some models come with BMW Mobility Kits in place of spare tires, particularly in performance-oriented M vehicles. The majority of other models have run-flat tires. These tires, also referred to as zero-pressure tires, give you the peace of mind that, even on a long-distance road trip, nothing other than a complete tire failure would keep you from reaching your destination or a repair facility. Run-flat tires have have advantages and disadvantages, though.

Change of Run-Flat Tires
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.
Can ordinary tires be used in place of run-flats?
You can, indeed! It’s advised but not necessary to swap out run flat tires for run flat tires. Here are some things to consider if you decide to switch your run-flat tires for regular tires.
- You should swap out all four tires at once when going from run flats to standard tires. Run-flat and regular tires shouldn’t be combined unless as a temporary measure. Combining regular tires and run flat tires can severely diminish a vehicle’s stability and handling because run flat tires are much stiffer than regular tires.
- Follow the tire manufacturer’s recommendations for size, speed rating, load capacity, and inflation pressure when choosing new tires.
- Many run-flat vehicles are not equipped with a spare tire or tire-changing tools. Check your car to see if you need to buy any new emergency supplies.
Recall that most leasing firms demand that vehicles purchased with run-flat tires be returned with them.
Can you combine different run-flat tires?
Similar to regular tires, run-flat tires create touch with the road through patches that are about the size of a man’s hand. To handle braking, cornering, and acceleration, the four patches must bend in all directions. The weight of the vehicle must also be distributed as evenly as feasible via these contact points. For performance cars in particular, this might lead to differing size front and rear wheels and tires to enhance balance and performance.
Tyres are an essential component of a car’s design, which takes into account where heavy components like the engine should be placed as well as where passengers and their luggage must fit. Just a few of the factors that tire manufacturers and automakers must jointly strive to achieve include the following ones:
- Comfort
- Braking Range
- Deflection Resistance
- bolster important parts like the suspension, the brakes, and the dynamic control systems
- Wear
- Acoustics
- Performance
The general belief is that it is not advisable to mix and match regular tires with run-flat tires. Installers of new tires advise switching all four tires from run-flat to normal tires at once. This is due to the imbalance that could potentially result from having two tires on either side of the vehicle that are made of different materials. If one tire has 50% stronger side walls than the other, think about how flexible the side walls will be during turns or under hard braking. Similar to how run-flat tires wear out more quickly than conventional tires, there will be an uneven wear between the two.
RUNFLAT TYRES CAN BE ORDERED ONLINE!
Customers frequently ask us if they can securely switch their runflat tires for conventional ones.
Most frequently, this is due to one of two causes:
- The journey is rough, difficult, and merciless, or
- The Run Flat tires cost a lot more money.
The response is generally “yes” But there are a few things to think about:
1. Your car will handle rather differently with the two different types of tires, thus it is strongly advised you replace all of them at once, or at the very least, an axle pair.
You don’t have a spare tire, either! If you have run flat tires installed, they are made to give you more mobility so you can get to a safe location, a place to get replacement tires, etc.
Therefore, if you install “regular” tires and get a flat tire, you’re essentially helpless!
This gives you the following choices:
- Carry a small compressor and a can of tire repair foam in the hopes that they will help to solve the issue momentarily.
- Purchase a spare to store in the trunk and don’t forget the tools and jack, etc.
- Call a recovery or mobile service!
3. *Somethings could not be honored if your car is still covered by the manufacturer’s warranty. Before making any changes to the original specification, it is recommended calling them.
4. You should definitely let the buyer know about the specification modification when selling your car!
Vision Illusion
I apologize in advance for asking what must be one of the top 10 questions: how to change from OEM run flats to “regular” non run flats.
After some discussion in a different post, I’ve decided I don’t like the idea of having different brands, different treads, and different compounds on the front when I’m breaking hard in the rain. I recently purchased a 2016 440i convertible (F33) with a Bridgestone Potenza and a Michelin Pilot Sport 3. In order to increase riding comfort, but especially to lessen the road noise beyond 80 mph, which is very prominent—at least to my ears—and the rears are also four years old, I’ve made the bold decision to swap all four tyres to non run flats.
Which tires are people using, then? Traction is a priority during acceleration and braking, whether it’s dry or wet. Noise comes in second, then comfort. Since I only use the car for fun and not as a “daily drive,” it doesn’t cover a lot of miles, so tire wear or purchase costs aren’t high on my priority list.
According to evaluations I’ve read, the Pilot Sport 4S and Goodyear Eagle F1 Asymmetric both appear to be good options. However, given my staggered sizes, I’d have to mix Asymmetric 2 and 5 tires, which is not ideal. With the exception of the fact that it is a little noisier than the two above, the Continental SportContact 6 seems like a good option.
I have 225/40 R19 front tires and 255/35 R19 rear tires. I suppose Y in terms of speed, but I’m unsure of the load rating. (Does anyone know a reliable source for information on BMW tires?) For OE run flats, MyTyres.co.uk is showing me 92Y and 96Y sizes. Which loading should I thus be looking for?
Can standard tires be used in place of run-flat ones, BMW?
RFTs have various benefits, including rapid steering reaction. When you have a flat tire, you can avoid changing a tire in the chilly rain and safely exit a busy freeway. You’ll be able to steer through the tire failure if one suddenly deflates with better stability.
However, some drivers complain that they are noisy and uncomfortable to drive. Particularly if you end up with a flat, they are more expensive. They don’t hold up as well as regular tires. It is particularly crucial to maintain proper pressure and make sure that the TPMS system is operational at all times because RFTs won’t visibly sag if the air is low.
Consider whether purchasing conventional tires and relying on a tow in the event of a flat would be more affordable and practical if you have a roadside assistance plan through your auto insurance or with AAA. (And think about whether having a spare might be preferable.) It’s acceptable to mount regular tires on your existing wheels if you opt to swap out the run-flats that came with your automobile for them. For as long as they are the same size, they will fit properly.
Are all BMW tires run-flat?
BMW made the decision in 2009 to make run-flat tires standard equipment on all of its vehicles. The brand’s partnership with Bridgestone gave customers better fuel efficiency and a safer way to repair a punctured tire. The benefits and drawbacks of owning a BMW are highlighted to assist owners in making that decision.
Can run-flat tires from BMW be repaired?
What should a fleet manager be aware of when using run-flat tires as opposed to non-run-flat tires? Manufacturers of tire and mounting and balancing equipment agree that run-flats are more challenging to mount and demount due to their special construction.
On the subject of whether run-flat tires can be mended, there is disagreement. The replacement tire limits and suggestions made by the vehicle manufacturer are frequently followed by tire manufacturers.
For instance, Michelin North America Inc. permits the repair of its run-flat tires (Zero Pressure) under specific conditions. But according to the owner’s manual, changing a BMW’s original equipment run-flat tires is not an option.
The U.S. Tire Manufacturers Association (USTMA) recommends the same run-flat tire repair techniques for both run-flat and non-run-flat tires. Prior to doing so, USTMA does advise vehicle owners to inquire about the tire manufacturer’s repair policy and, if appropriate, suggested repair techniques.
