The MS plus 77 uses a new silica compound specifically for wet winter conditions. It allows the tyre to interlock more efficiently with the road surface, giving you greater grip as you drive.
The compound supports the rigid shoulder blocks which help maintain lateral stability as you corner. The better the adhesion, the better the handling on wet roads.
In many European regions you’re now more likely to encounter rainy days in winter than you are snowy ones. So it’s important your winter tyres offer excellent performance in wet as well as icy conditions.
The MS plus 77 has a special V-shaped pattern with wide, open channels. This unique design allows surface rain water to be easily displaced, giving you a safer drive in wet conditions. With the tyre maintaining its grip on the road, you stay in control and your risk of aquaplaning is reduced.
If you look closely, you’ll see that the MS plus 77 has a large amount of thin grooves on its surface. These act like mini snowploughs, breaking up the surface powder making it considerably less slippery.
Look even closer and you’ll notice that every groove has a tiny bumper. This holds the cavity open so that more water can flow through. This, in turn, means more water is removed from the road’s surface and your traction and braking performance is improved.
AutoBild also tested winter tyres again in 2015. Fifty winter tyres from various manufacturers took part in the test. The capabilities of the winter tyres were evaluated in four categories: snow, wet, dry and cost. The Uniroyal MS plus 77 was rated highly for its excellent value-for-money.
The ADAC winter tyre test is generally seen as the most exhaustive and advanced tyre testing programme. In collaboration with Stiftung Warentest and other consumer organisations, Germany’s largest automobile club (Allgemeine Deutsche Automobil Verband –ADAC) tests winter tyres according to numerous relevant criteria. The Uniroyal MS plus 77 regularly absolved the tests with top marks for performance on snow and wet roads.
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.
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.
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.
