Tyre reviews: best car tyres to buy now 2022
With car makers fitting ever-bigger wheels to their latest cars, it was high time we returned to 18-inch rims. And it was not just a return to this size of wheel, which we last tested in 2016, but some sort of normality, too, because this year’s programme was not affected by the pandemic.To get more news about austone tires, you can visit gofortunetire.com official website.
We also headed back to Bridgestone’s Aprilia proving ground in Italy to assess the tyres. There were no returnees from our 2016 test, but a few regulars were missing thanks to stock problems or new designs being launched imminently.
Given that this size overlaps with bigger, more sports-orientated versions, we asked tyre makers to nominate their UHP (ultra high performance) offering rather than the UUHP (ultra ultra high performance) tyres we mini-tested seperately.
Where possible, we bought tyres to ensure we tested what you can buy, plus we added a budget Far Eastern brand. The key handling and braking tests were performed by Auto Express drivers, with the remainder completed by proving ground staff in Aprilia. Rolling resistance was rated at Bridgestone’s nearby Castel Romano RD centre.
What we tested
We opted for the biggest-selling 18-inch tyre size, 225/40R18, and all of the models we tested had 92 weight and Y speed (up to 186mph) ratings. We’ve also given each tyre’s EU tyre label rating (right). Fuel economy (RR) and wet grip (WG) are rated from A-E, with A the best. Pass-by noise (N) is rated in decibels, so lower is better.
A key area for many drivers because these are the conditions where they are most likely to exceed their tyres’ limits. We looked at braking and cornering, both in shallow depths plus how the tyre copes with deeper standing water. As in our SUV tyre test we used the revamped wet handling track at Bridgestone’s proving ground, which has had new corners added and others altered. The 1.7km circuit provides a good test of traction out of tight hairpins, lateral grip and front/rear balance through longer turns. Lap times formed the result.
Braking performance was assessed from 80kph (50mph). Using instruments, we measured the distance taken to slow our test car to 20kph (12mph); we then calculated how much farther it would have taken to come to a stop to avoid influence from the anti-lock braking system.
As in the wet, lap times were at the heart of the handling test around the circuit, which not only allowed lateral grip to be assessed but also the balance each set provides. Braking measured the distance taken to stop from 100kph (62mph).
While the EU label rating concentrates on pass-by noise, for drivers the level in the car is key. So our test was done at 50 and 80kph and measured sound levels between 100-400Hz.
Rolling resistance is the key factor here, dictating how much fuel it takes to roll a tyre at a given speed. Our test was done to industry standards and a one per cent difference in fuel use requires around a four per cent change in rolling resistance.
