Highlights

Aquaplaning

Like its sportier sister, the RainSport 3, the RainExpert 3 relishes the rain. With its Shark Skin Technology, featuring longitudinal grooves and innovative tread structure, it minimises water turbulence and quickly channels water away. So while you're enjoying precise handling on wet roads, it's protecting you from aquaplaning.

Grip

The RainExpert 3 has a flow-optimised asymmetrical tread structure and a tread compound that has been specially developed for strong grip in the wet. It features large outer shoulders, with lateral stiffness, for high grip while cornering.

The tyre is rated grade A on the EU Tyre Label for wet grip, indicating the highest possible performance in wet and rainy conditions.

Fuel economy

The tyre’s tread pattern has been designed for an optimised contact patch with the road, leading to reduced friction and a lower rolling resistance on all road surfaces (the energy needed to keep your tyres rolling at a steady pace). This low rolling resistance will save you money at the fuel pumps.

Test Reports: Uniroyal tested by independent tyre experts

‘Good safety reserves in aquaplaning, good lateral stability and well-balanced handling in the wet.’

Eighteen summer tyres took part in the AutoBILD test. The test criteria evaluated the performance on a wet course (longitudinal aquaplaning, lateral aquaplaning, handling, circular track, braking), on a dry course (handling, braking, ride comfort, pass-by noise) and analysed costs (lifecycle, overall lifecycle costs, rolling resistance). The Uniroyal RainExpert 3 impressed the testers with good results on wet road surfaces.

EU tyre label

Wet Grip:

Tyres with high wet grip performance (A or B graded) have shorter braking distances on wet roads and are, therefore, safer in the rain. As with fuel efficiency, the D grade isn’t used and there are no plans to use G.
Fuel efficiency:

Tyres account for up to 20% of your vehicle’s fuel consumption so, if you want to get more miles per tank of fuel, you should choose tyres with a high fuel efficiency rating. You will also lower your CO2 emissions. It comes down to rolling resistance i.e. the energy lost when a tyre is moving. The lower the rolling resistance, the less energy is lost and the lower your fuel consumption and CO2 emissions. The difference between an A-rated tyre and a G-rated tyre could be as much as 6 litres per 625 miles.
Rolling noise:

This is the external noise made by the tyre and is measured in decibels. The more filled bars shown on the label, the louder the tyres.
