Can You Replace Run Flat Tires with Regular Tires?

Have you ever wondered if you can replace the run flat tires on your vehicle with regular tires? As vehicles become more advanced, questions like these arise for many owners and drivers. Well, you actually can switch out run flat tires for regular ones, but there are some important considerations to factor in before making the switch.

Here’s a quick answer:

Yes, you can replace run flat tires with regular tires on most vehicles. However, you’ll lose the key safety benefit of being able to drive up to 50 miles at moderate speeds if a tire fully deflates. Also factor in potential compatibility issues, the need to carry a spare if you didn’t before, and getting the tire pressure monitoring system recalibrated. Consult an experienced tire shop to see if switching tire types makes sense for how and where you drive.

What are Run Flat Tires?

Run flat tires are a special type of tire engineered to resist rapid air loss and enable drivers to travel reasonable distances at reduced speeds in the event of pressure loss due to a flat.

They have reinforced sidewalls that are strong enough to prevent the tire from becoming completely flat right away even if punctured. Many newer vehicles come equipped with run flats from the factory.

Pros and Cons of Run Flat Tires

There are both pros and cons to run flat tires versus regular tires:

Pros

  • Allow you to safely drive 50 miles or so to get your vehicle repaired even with a fully deflated tire
  • Can be driven deflated so you avoid being stranded somewhere inconvenient or unsafe
  • Provides great reassurance and safety if you don’t have a full-sized spare tire

Cons

  • More expensive than comparable standard tires
  • Slightly heavier than standard tires, which may impact fuel efficiency
  • Harsher ride quality due to the stiffer sidewalls
  • More difficult to assess tire pressure since they don’t deflate as quickly during slow leaks

Key Factors to Consider with a Tire Type Switch

If you do decide to swap out the run flat tires on your car and replace them with regular tires, there are some key factors you’ll want to take into account:

Loss of Run Flat Safety Features

Obviously you’ll be losing the capability to safely drive for some distance with a fully deflated tire. So consider how much this loss of safety and reassurance matters for your driving needs. Make sure you have a spare tire and the ability to change it if needed.

Vehicle Compatibility Factors

Some vehicles are specifically engineered around the size, weight and performance characteristics of run flat tires. Switching to lighter, more flexible regular tires can impact steering, handling and suspension. Speak to a qualified tire shop about compatibility.

You also may not have space for a full-size spare if run flats were originally equipped, since they take up less space when deflated. Check if you have room to carry a spare tire and related equipment.

Tire Pressure Monitoring System Recalibration

Many cars with run flat tires have tire pressure monitoring systems optimized for that tire type. When you install new regular tires, the sensors will need to be recalibrated by a qualified mechanic. If they are not, you risk inaccurate pressure readings.

The Bottom Line

While you can install regular tires in place of run flats on most vehicles, carefully consider the loss of safety, any compatibility issues, and required TPMS sensor recalibration first. For many drivers, keeping run flat tires is the way to go for the security they provide in the event of a flat tire at an inconvenient time or place. But with proper planning and precautions taken, regular tires can work too. Consult a knowledgeable tire shop if you decide to move forward with the switch.

FAQ

1. Do I need special rims to mount regular tires if I currently have run flats?

Not necessarily. Most run flat tires are mounted on standard rims. However, some performance vehicles use unique rims engineered specifically for run flat tire sizes, so you’d want to verify compatibility.

2. Can I drive as fast with regular tires versus run flats?

Yes, you can drive at normal highway speeds with regular tires. The speed restrictions on run flats only apply when they are deflated, which allows you to drive 50mph or so to get repaired.

3. Will switching to regular tires improve the ride quality and comfort?

Most likely, yes. The rigid sidewalls on run flat tires mean ride comfort is often compromised. Regular tires will cushion the ride better leading to a more comfortable drive.

4. Do I need to keep run flats on my vehicle for the warranty to remain valid?

Usually not, but check your owner’s manual to confirm. Most warranties remain intact even if switching to regular tires, as long as they are the correct size and speed rating.

5. Is it less expensive to replace run flat tires with regular tires?

In most cases, yes. Quality run flat tires are substantially more expensive than comparable standard tires, so you may save money long-term by converting to regular tires. Just account for any costs like adding a spare tire.
