The big summer tire special 2015
The summer tire assembly: safety before rule of thumb
In order to better determine when to switch from winter to summer tires and vice versa, the “O to O” rule of thumb has been established - summer tires from Easter to October, winter tires from October to Easter. For many drivers, the rule is sufficient, but the time should ultimately always be made dependent on the individual driving requirements. In addition, there are other aspects like that Tire pressurethat should be taken into account, but are often more or less neglected.
Changing tires before Easter can be too early
Perhaps one or the other reader may think that it is still a little early in the year to point out the need to change tires from winter to summer tires. However, since the “Easter to October” rule is decisive for most motorists and articles remain on the Internet for years, it is almost too late to point out the need to change tires. Easter is determined by the moon and begins on March 22nd or April 25th at the latest. April 25th is certainly appropriate for the tire change, but not necessarily March 22nd.
The optimal time depends on the individual driving behavior
Especially those who travel a lot across the country and also at night should always consider contingencies. Even if the temperatures during the day are already beyond the 10 degree mark, there are some road areas and circumstances that certainly pose a risk of ice and frost:
- nighttime temperatures
- Precipitation that evaporates during the day and freezes to frost at night
The basic rule is to wait a little longer than act hastily. A few liters more fuel consumption or maybe 1.000 km less mileage due to slightly stronger rubber abrasion during the day are far cheaper than an accident on slippery roads. Apart from possible personal injury. So the date for changing the tires should always be adapted to your own requirements.
Minimum profile and age of summer tires
In general, security plays a crucial role. If the summer bikes from last year are used again, they should have been properly stored. This is preferably done lying on the rim or on wall hooks, The minimum profile of 1,6 mm is also relative. The driving characteristics are already significantly deteriorated at this time. Just inexperienced drivers should change the tires a bit earlier. In addition, not all tires reach this minimum profile within a few years. But the rubber compounds change over the years. Plasticizers fade, the tires become hard and porous. At least then it is time to exchange the old tires for new ones. Online you can at the tire dealer Tirendo a matching tire to find a replacement.
The EU tire label: new tires in different aspects
The DOT number on the carcass (tire sidewall) provides information about it. After a maximum of seven years, the old new tires should give way. Who does not drive his tires in all areas to the limit, can make up for additional costs by the appropriate tire choice. Within the EU are New tires equipped with a label, which gives information about tire quality, average fuel consumption and abrasion. For frequent travelers also the rolling noise should be relevant.
Change the tires yourself
If you want to change the tires yourself, you should have the following tools in addition to the standard tool:
- wire brush
- rust remover
- Copper or aluminum paste
Torque wrenches and air pumps are also recommended. Aluminum rims in particular, but also wheel bolts and bolts, really stick through oxidation, while on winter wheels, corrosion is additionally promoted by road salt. Spraying the wheel bolts or screws the day before with rust remover works wonders. When changing used bikes on the same side from front to back (and vice versa), but never diagonally. More information on the process of changing tires is also available described in this article.
Care and maintenance during operation
The nuts or screws are first greased or smeared with the paste as well as the hub cleaned with the wire brush. Then they are slightly tightened crosswise and tightened with the torque wrench. Depending on the size of the screw (for 17, 19 and 21 cars), the tightening torque is between 100 and 130 NM. Then check the air pressure, which differentiates between the pressure at operating temperature and cold tires. How high the pressure should be is often indicated on the B-pillar, on the inside of the fuel filler flap or in the operating instructions. In addition, the air pressure should be measured at least once a month. But also the wheel bolts are checked again after 50 km. If the winter tires are properly stored again, it can already go to the funny easter egg hunt.
