How to tell if a Michelin tyre is a run flat?
Michelin signify that a particular model is a Run Flat tyre by printing ZP on the sidewall of the tyre. Michelin Primacy MXM4 ZP (Runflat) 245/50R19 101V BSW Tires.Run-flat tires are marked differently on their sidewalls by various tire manufacturers. Look for designations such as SSR, EMT, ZP, DSST, EMT RFT, SSRF, TRF, or ZPS to identify run-flat tires. These markings indicate that the tire is designed to run safely without air pressure for a limited distance.Michelin signify that a particular model is a Run Flat tyre by printing ZP on the sidewall of the tyre. To find out whether the tyres currently fitted to your vehicle are Run Flat tyres, check to see if this symbol appears on the sidewall.
Do run flat tyres need higher pressure?
Unlike conventional tyres, which require air to stay hard, run flat tyres have a reinforced sidewall, meaning they stay rigid without any air pressure. The reinforced outer shell of run flat tyres keeps the rubber in place without air, supporting the car as you continue your journey. Run flat tyres are OEM equipment on many new cars and they’re an important safety feature. But they can give a stiff and bumpy ride, they’re more expensive than conventional tyres and they can’t be repaired meaning you will have to replace them after a puncture.Run flat tyres are designed with a reinforced sidewall to allow continued driving even after a puncture, but this design comes with trade-offs. Due to their stronger construction, they generally have higher rolling resistance compared to regular tyres, which can lead to a slight reduction in fuel efficiency.High replacement cost: Drivers often think about the cost of replacement as one of the most significant downsides to run-flat tires. But the thick sidewalls that make them so good at their job have a significant impact on ride quality.There are two primary categories of run-flat tire systems: Because of the thicker sidewall, it is much more difficult to puncture the side of the tire, which is beneficial because a sidewall puncture causes more damage to the tire than a tread puncture does.
Can I mix run-flat and normal tyres?
It is not recommend to mix run flats with regular tyres. Although there are no laws or legislation against mixing run flats with standard tyres on a car, doing so can have a negative impact on the handling of the vehicle. Run flat tyres may wear out slightly faster than standard tyres, depending on driving conditions and maintenance. The stiffer sidewalls contribute to a firmer ride, which can lead to increased tread wear, especially if the vehicle’s suspension is not specifically tuned for run flats.Run flat tyres are OEM equipment on many new cars and they’re an important safety feature. But they can give a stiff and bumpy ride, they’re more expensive than conventional tyres and they can’t be repaired meaning you will have to replace them after a puncture.It is advised that you do inform your insurer if you decide to switch from run flats to regular tyres. This is because the change is classed as a material change to the car. A car that is equipped with run flats as standard has likely been designed to be used with run flat tyres.In addition to being cheaper to buy, normal tyres can also be repaired and reused after a puncture. In most cases, this is not possible with run flat tyres. It is also worth noting that, in normal circumstances, standard tyres provide a smoother ride than their run flat counterparts.
