Vredestein Tyres – A good winter and summer tyres

Winter season is not only the time of the year wherein you are about to go out to create your frosty snowman instead it is the season where you are going to change your car’s gears particularly the tyres. In the northern or mountainous region of Europe, locals are actually required to fit winter tyres, in fact, their law state that tyres must be changed every 10 years however, it was changed into 6 years to ensure your safety. Vredestein brand will always be the usual mention among locals. Vredestein winter tyres’ design cuts through snow and into ice to give a far greater margin of safety than with normal tyres. It can supply a large range of Vredesten summer, winter or all season tyres made for a wide range of vehicles, from cars, vans to motorbikes. Unlike those summer-spec tyre which is less able to adapt to the contour of the road surface reducing its grip levels. Winter 4 Xtreme, Showtrac and Showtracs 3 , 2 are just few of the ranges included in a Vredestein winter tyres which gives off a high quality, fantastic stability and grip. One tyre with its outstanding scores on wet and snowy surfaces such as the Vredestein Quatrac 3. It is a balanced and versatile tyre with perfect steering and handling coupled with a short braking distance on both wet and snowy surfaces. It is completely the optimal alternative for those who wants to use a single type of tyre for both summer and winter seasons instead buying two different models which could be more expensive.

If you wish to have tyres with a very good steering and handling characteristics, you can experience it with Vredestein Ultrac since it has been its strong points. The tread construction, shape and contours are optimised for every size and offers a maximum design quality. While Vredestein Sportrac 3 has its rounded footprint with its even surface which helps braking distance and improve traction, superb handling and water dispersion. Vredestein Ricorso tyres,on the other hand, are marketed and designed for training or racing. An affordable performance tire with excellent ride characteristics especially ideal for recreational use because of its comfortable touring and training tyres.

Of course, the difference between summer and winter tyres are even greater. There are more influences and factors that are in need for consideration. One thing is the pressure. Winter tyres are recommended to have inflated to a slightly higher pressures than the summer tyres so that it won’t heat up as much as the cold weather. Another thing that would affect its performance is the tread. As the tyre’s tread aged, it becomes less supple and less grippy. That’s the reason why there’s a need to change tyres once in awhile. However, Vredestein tyres are just the brand that you’re looking for, imagine this tyre is often used for all-season, whether its for summer or winter days. It might not be as good as those summer tyres, but it definitely has a big impact on longevity and performance on wet and dry roads.

Cross Ply tyres versus Radial Ply Tyres

Cars make use of the radial tyres entirely but the ones fitted to motorbikes retain the cross-ply form of construction and even the tyre engineers state that radial tyres are not appropriate for motorbikes. This is in fact quite right as cars and motorbikes are very different and should have different tyre requirements. However, of late the radial tyres are considered to have benefits to offer to motorbikes as well.
Several piles of cord are laid on top of each other at a bias angle of 40 to 50° to make a cross ply tyre. This consequence in the creation of a cross at an direction of 80 to 100°. The layered and angled structure of ply tyres results in the tread not reacting in exact symmetry to that of the loads applied.
The symmetry is completely lacking in cross ply tyres and this can cause the tyre to run to one side nonetheless while rolling on a completely level and even surface. This effect is known as “Ply Steer”. The cross manufacture of the carcass efficiently forms parallelograms of thread imbedded in the rubber, this is not a sturdy form of construction and under driving or braking torque, upright load and centrifugal sound effects these parallelograms deform, which allows squirming of the contact area and tyre toss or diameter enlargement at elevated pace, reducing constancy and heating the tyre. Such heating eventually manifests itself as amplified rolling conflict.
By simple observation one can conclude that radial tyres create a greater and wider area of impression compared to the cross ply tyres. Such a fact highlights that radial tyres have better grip than cross ply tyres. Again in loaded conditions the radial tyres outscore the cross ply tyres as they have larger contact area with the surface of the road as they the tendency to become littile bit flat which is not the case in cross ply tyres.
Radial tyres contain less plies that is generally confined to one or two than the cross ply tyres that require three to four plies, so as to have greater flexibility in sidewalls. To maintain the entire tyre stiffness the reduction of sidewall height is required and thus results in lower profiles of 50 to 70 %. On the other hand the cross ply tyres make use of 90 to 100% of the profile. The lower profiler is an indication of having smaller diameter. The cross ply tyres have larger diameters in comparison to radial tyres of the same size. This trend contributed to the growth of 17” wheels while leading to the decline of the popular 16” wheels.
In the year 1984 radial tyres were introduced for the first time. The bias belted tyres were the most commonly used tyres until then. The cross-ply tyres were the next in line of production, which added circumferential belt plies. As and when the developments took place the older technology got replaced with newer ones giving way to improved tyre strength, agility and overall performances.

Properties of tyres

Tyres are an integral element in any bike and their main function is to transmit all the forces amid the bike and road. The properties of tyre are one aspect that is better if it remains constant. The tyres are the key to the handling properties of bikes. The vehicle manufacturers specify the properties of the tyres that are provided along with the new bikes.

But the same cannot be said about the after market tyres which are completely different from the original tyres. Even if they may be similar in design their handling characteristics can differ a lot since the forces generated between the tyres and the ground will determine the machine’s behavior.

The engineering involved or the sophisticated designing and fabrication in manufacturing of tyres is always hidden from the users due to the simplicity and multitude of tasks they are able to achieve. The earliest versions of pneumatic tyres were used for increasing the comfort level and decrease the load on wheels. The modern day bikes make use of suspension systems but it is the tyres that are responsible for absorbing the initial shocks from road.
The various criteria depending on which the tyre has to be chosen depends on:
 Driver’s safety
 Handling
 Comfort
 Service life
 Economy
 Environmental compatibility
Ensuring the driver’s safety is of prime concern and this is achieved by letting the tyre to sit firmly on the rim. Such an arrangement is possible by implementation of a special bead design and making use of safety rim.

Handling of tyres is also a key feature that allows one to make decisions based on the type of vehicle they will use. Smaller vehicles should be provided with thin tyres for better handling and larger ones such as cars or trucks may need broader and bigger or smaller tyres to achieve the same.

Compromising on the comfort by going for style is never advisable. Lean and thinner varieties of tyres may be quite appealing to use but one should tread with caution and always look for tyres that are recommended by the manufacturer and should not opt for cheaper variants as well.

The tyres come with a shelf life that is mentioned by the manufacturer and one has to take care to purchase tyres that have longer shelf life and only buy the original ones to avoid problems related to its cheaper variants. Tyre manufacturers also offer free services for increasing the longetivity of the tyres and repair some of the minor wear and tear too.
