Switching From Run Flats To Regular Tires

Tires the tough round rubbers that a car wheel. They support the weight of your car and allow it to move, maintain and change directions. They are one of the most-used components of your vehicle and are susceptible to wearing and tearing. Hence, they need to be changed either because they are worn, punctured, torn or because they are old. Just like any other tire run-flat tires will also require changing one time or another.

If your car moves on run-flat tires you probably question whether or not you can switch them to regular tires. We shall give our thoughts on this and answer some other questions you probably have. 

What are Run-flat Tires

Run-flat tires are also called zero-pressure tires. They are tires that allow you to keep driving your vehicle even when deflated. Its technology gives you just enough time to drive down an automobile shop for a fix. Also, vehicles that ride on run-flat tires usually have a Tire Pressure Monitoring System.

Can You Switch Your Vehicle From Run-Flat Tires To Regular Tires?

If you intend switching all four run-flat tires to regular tires and not a mixture of both, you can. Just ensure to follow only what the car manufacturer endorses while replacing the tires. 

Understand that both run-flat tires and regular ones have their peculiarities. Run-flat tires were created to give your car the luxury of safely moving a short distance even when punctured. They are called zero-pressure tires because they can still support your vehicle with little air pressure in them. Even though it is only for a short distance. Run-flat tires are also more resilient because of their additional reinforcement.

There are some facts to consider when you want to change your car tires to regular ones. Especially, if your car was manufactured with run-flat tires. For one, cars originally made with run-flat tires may have no provision for a spare tire or a hand jack. Those are the tools used for changing your tires when punctured. This is because run-flats were designed as a way-out for such problems. Hence, you will be needing some emergency if you plan on switching to regular tires.

Also, when changing from run-flat tires with normal tires your car may experience some malfunction in the car-alarm and computer. Also, ensure the new regular tires meet the car manufacturer standards for a tire.

Can You Run A Vehicle On Both Run-Flat Tires And Regular Tire?

No, you should not have your car riding on both run-flat tires and regular tires. You should stick with either and have both on your vehicle. This is because it can lead to an imbalance when you drive. However, in case of an emergency, it may be allowed only temporarily.

Can A Run-Flat Tire Be Repaired?

A run-flat tire may be repaired depending on the degree of the puncture on the tire. However, such repairs are not recommended. When a run-flat tire gets punctured its repair is difficult. This is because underlying damages following the puncture may not be easily identified because of the reinforced sidewalls. This invariably means that a patched run-flat tire may have its safety compromised. What you should do is to have your run-flat tire replaced with a new one as soon as possible.

Whatever you decide either changing to a new one or repairing the damaged one, ensure it’s done to be a skilled technician. Most times, however, tire technicians avoid repairing a run-flat tire.

How Would You Know A Run-Flat Tire Is Punctured?

Vehicles that run-flat tires should have a tire pressure monitoring system (TPMS). Now, when the TPMS shows that the tire is losing pressure, that’s a sign the tire is punctured. Your vehicle manual will tell you the tire air pressure range and what speed to travel with it. Drive with the limit speed to the nearest auto shop for a repair replacement.

Advantages Of A Regular Tire Over A Run-Flat Tire

Compared to run-flat tires, regular tires are more economical. On average run-flat tires cost about 200 to 500 dollars per tire while a regular tire is about 50 to 200dollar.

Regular tires also give a smoother ride compared to run-flat tires. Because of their reinforced sidewalls, run-flat tires are louder and stiffer while driving.

Certain researches reveal regular tires as being more durable than run-flat tires. On average regular tires will cover 6000 miles more than a run-flat tire before needing a replacement. However, this statement is subjective. How a driver drives and where a driver drives influences the durability of the tire.

Advantages Of The Run-Flat Tire Over A Regular Tire

A major advantage of the run-flat tire is you can still drive a distance after a puncture before changing your tire. You don’t have to be stuck on the road with a flat tire. Also, compared to regular tire run-flat tires are safer when you have a sudden tire burst. Because they can run on low pressure you have better control of your vehicle even when suddenly perforated.

The Disadvantage Of A Regular Tire

A drawback of a regular tire compared to run-flat is the tire must be changed immediately following a blowout. Also, there is the risk of the driver losing control if on high speed when the tire had the burst.

The Disadvantage Of A Run-Flat Tire

It is costly and cannot absorb the pressure of speed bumps or potholes when driving. Run-flat tires also produce more noise while driving compared to regular tires. All these may reduce the comfort of a ride. There is also the problem of availability. Compared to regular tires, run-flat tires are limited in sizes and availability.

Are Run-Flat Tires Good Tires

Run-flat tires are good tires. When suddenly deflated, they offer better stability. They reduce the car weight making it more gas effective. They also keep you from being stuck on the road with a bad tire. Although the run-flat tire has its disadvantages too.

How Long Do Run-Flat Tires Last

Run-flat tires can run for 5 years or 60,000 miles. Although this can be influenced by how good the driver maintains the tire.

How Long Can A Car Sit On A Deflated Regular Tire

A car should not be allowed to sit on a flat/deflated tire for too long. The tire should be changed within the shortest time possible. For regular tires, you risk damaging the tire beyond repair if allowed to sit for a long period. The rims are also at risk of rusting especially if left to sit during the rain. Generally, a car shouldn’t sit on a deflated tire any longer than overnight.

Can A Flat Tire Be Kept Overnight?

If parked in a safe space and not driven then it can be allowed overnight. However, it is better if the tire is removed on the same day the flat was noticed. This will relieve the tire from taking on the car’s weight.

How Can You Avoid Having A Flat Tire

Having a flat tire is usually unplanned and sometimes may be unavoidable. However, here are some precautions you can take to prevent a flat tire.

Firstly, use the right type and sizes of tires for your car. While at this avoid increasing the gross weight of your car by overloading it. This is because the tires bear your car’s weight and an overload will increase the pressure on the tires. 

Secondly, regularly carry out a pressure gauge on the tire and vulcanize it when necessary. This will help prevent deflation. Also, carry out other checks on the tire and fix any identified problem early.

Thirdly, drive safely and carefully. Avoid potholes, sharps and other road harms when you can. Obey traffic rules and road signs. Before setting out for the road ensure your vehicle is for enough for the journey. Also, seek the help of an automobile specialist early when a car problem with the tire arises.

Can You Drive On A Flat Tire?

Yes, it is possible to drive on a flat tire but you should not. At least not over a long distance. It is risky and unsafe. You can end up in an accident and lose control of the vehicle. You should move the vehicle away from the road to a safe zone though but do not continue the journey on a flat tire. While moving to a safe region drive slowly and carefully. Do this to ensure your safety and prevent further damage to your rim and tire.


Switching from a run-flat tire to a regular tire should first be thoroughly taught. Both the regular and the run-flat tire has its advantage and disadvantage over the other. If your vehicle was manufactured with run-flat tires, there are factors to consider before making a switch. More importantly, ensure the new regular tires meet with your car manufacturer specifications.

Also, when you have a deflated tire you should drive slowly, move to a safe space, and change the tire. Avoid travelling long distances on a deflated tire.
