Does the statistic that every driver experiences a flat tyre between 62 000 and 93 000 miles on the road worry you? The run flat tyres available at Tyres Guru vanish such worries by greatly enhancing safety for drivers. These are not your everyday conventional tyres.
Run flat tyres are exclusively designed tyres that provide safety in case of an emergency - air loss or puncture. In an event of a puncture, the run flat nature enables you to continue driving up to 50 miles with a maximum speed of 50 miles per hour so you don’t need to wait for a tyre fitting service to come to your aid.
This is especially important in the colder season when you need to rely on your tyres' performance the most. Please remember that, regardless of the speed rating of your tyre, you shouldn't drive faster than 50 mph. A wide range of cheap run flat tyres by various tyre manufacturers in almost any tyre size are available at tyres-guru.co.uk .
There are two types of run flat tyres: self-supported and ring-supported. Both design types consist of the following two elements:
The difference between the two designs is in the way these tyres keep the vehicle on the road safely even when punctured:
It's very important to remember that this innovative design comes at a price. These tyres are definitely more expensive because of it. Don't forget that, once punctured, you can't drive them over the 50 mile limit (regarding both the speed and distance), otherwise, you're risking damage to the wheel.
Also, one must take into consideration that a tyre with run-flat technology can't be repaired once damaged. So, even though you'll definitely get safer from A to B in an event of a puncture, you'll have to replace the punctured tyre(s) before your next trip in your automobile.
Whether or not a tyre has the run flat technology can be determined by looking at the tyre sidewall. The two most common ones are RSC and RTF, but a tricky thing is that different manufacturers have different abbreviations. Please consult the list to see the correct tyre markings:
Many car manufacturers are continually deciding to include run flat tyres in their vehicles' original equipment to add that final bit of extra safety to their offer. Such vehicles are BMW 5 series or Mini.
So, if your new car doesn't have a spare wheel, most likely it's equipped with four run-flats. If that's the case, please contact the vehicle manufacturer if, for some reason, you want to replace them with regular tyres. One of the reasons could be that you can't repair run flat tyres once they're damaged.
There's no need to change the tyres on the spot: you are not forced to stop your vehicle in an inopportune moment or a place. This type of tyre gives you more than enough time to drive your car to safety. Plus, there's absolutely no need for a tow truck no more.
Punctured run-flats give you way more stability and driving comfort than conventional tyres. As they're designed to withstand air loss, driving with run flat tyres removes the danger of damaging your rim and gives you more handling comfort.
Also, driving with the run-flat technology translates to more trunk space, as there's no need for a spare tyre. Even though the tyre pricing does go higher with these models, it's a small price to pay for an overall increase in your driving safety.
For the most part, no. They should only be fitted on cars with the TPMS installed. So, if your car isn't equipped with this system, there's no point in equipping it with a set of tyres dependent on that system. Basically, without the TPMS, you wouldn't know whether or not your tyre is punctured, thus rendering all the benefits of the run-flat tyres useless.
Repairing run flats is generally frowned upon by both the tyre manufacturers and car manufacturers. In the case of BMW run flat tyres, the manual clearly states that repairing these tyres is not recommended. However, there are manufacturers that do allow run flat tyre repair.
Tyre manufacturers that permit repairs:
Tyre manufacturers that don't recommend, don't endorse, or flat out disallow repairs:
*Complimentary replacement first year or first 2/32" of wear (regardless of which happens first). Continental warns that a repair to one of its tyres discredits all other manufacturer's warranties.
**Complimentary replacement first year or first 2/32" of wear (regardless of which happens first), then administered until wear reaches 2/32" of remaining tread depth.
It might interest you to learn that the first type of tyre that resembled what the Run Flat tyres are today, was designed by Michelin in 1934 for the use of military vehicles. It will have been well over 20 years until this invention went public. The first commercial attempt was made by Chrysler and Goodyear Tire and Rubber Company in 1958 with the model called the Goodyear Double Eagle and it was advertised as "a tyre in a tyre".
