Are Run-Flat Tyres Worth the Cost
If you’ve bought new tyres within the past few years, you’ve likely heard of run-flat tyres. They’re built with extra-stiff sidewalls that support the vehicle’s weight in the event of air pressure loss. When a vehicle is equipped with run-flat tyres, they can prevent the control loss that typically accompanies a tyre blowout, and they allow you to continue driving until you make it to a place where it’s safe to do repairs. While these benefits are important, for some people, they’re outweighed by the disadvantages. Read on to learn why you should reconsider getting run-flat tyres.
A Rocky Ride
With very few exceptions, run-flat Michelin tyres feel like they’d be more at home on a Flintstones-era vehicle. The tread surface rests on an exceedingly stiff sidewall, and when you add in the additional unsprung weight, you’ll get lower performance and a bumpy ride, even if you’ve upgraded your vehicle’s suspension. In many cases, there isn’t much difference between how these tyres ride while inflated and how they work when they’re flat. That can be a big issue, for the reasons listed below.
They Don’t Look Flat When They Actually Are
Because a run-flat tyre’s sidewalls don’t collapse with air loss, you can’t tell when it’s flat simply by glancing at it. That’s why run-flat BF Goodrich tyres require TPMS, or a tyre pressure monitoring system. The TPMS monitors alert you when the tyre loses 25% of its air, but the system isn’t foolproof yet—and in many cases, it’s prohibitively expensive. This used to be a big issue when carmakers wanted to equip cars with run-flats, but it’s less of a factor now that TPMS is mandated on new vehicles. Knowing when a tyre is going flat is vital, because….
Run-Flats Have a Lowered Range When Flat
Most run-flat tyres will roll for about 60km after they go flat. That’s a decent range before a complete failure, but going even a portion of that distance will cause enough damage to warrant a new set of Nitto tyres Are Run-Flat Tyres Worth the Cost 1. If you’re dealing with a flat tyre that can’t easily be repaired, and you’re far from a repair shop, you’ll likely have to replace the tyre anyway. While most people think they can simply pull over and put on the spare tyre, they soon realize that….
No Spare Tyre is Available
In most cars equipped with OEM run-flat tyres, the manufacturer doesn’t offer a spare tyre. It seems like the primary reason automakers opt for run-flats isn’t that they’re safer, but that it allows them to justify not adding the weight and cost of a spare wheel and tyre. While lacking a spare tyre on a 4×4 Australia can be a serious problem, the ‘repair kit’ provided by some manufacturers is a real slap in the face. If a serious impact damages a run-flat tyre to where it needs replacement, you may be on your own because….
Run-Flats are Expensive and Hard to Find
If you find yourself needing to replace a run-flat tyre, you may have to head to your local dealership. However, they’re not always well-stocked, and some will simply refer you to a chain store that sells Continental tyres. Not all run-flats are hard to replace, but many are difficult to find—and almost all are more expensive than their conventional counterparts in a similar size.
When It Comes Down to It, Are Run-Flat Tyres Worth the Investment?
In our opinion, run-flat tyres may not always be worth the expense, the hassle and the effects on vehicle performance. The most effective way to handle a deflated run-flat tyre is exactly the same as with conventional tyres—simply pull over as quickly as possible and change the tyre to avoid a costly replacement. However, carmakers have made this strategy largely impossible; with TPMS, you’ll have enough warning of a flat to save the tyre before it needs to be replaced. In short, for most drivers, run-flat tyres do not offer enough benefits to offset all the potential drawbacks. Consult a 4×4 superstore of 4×4 rims and tyres Sydney for buying advice.
