In recent times, comfort problems on passenger cars with larger rims and wider tires have increased in number, and STRO has therefore developed a small recomendation and mounting instructions for tires on these vehicles, which can be good to use on these occasions. Learn more about how to avoid and fix problems like this.
Comfort problem passenger cars
Now that the cars have got larger rim diameter, and tires for high-performance cars, and that tires with runflat technology are more common on the market, many workshops have had to spend much more time solving comfort problems, which has also resulted in more complaints, often then tires that have been found adequate for use.
This also places higher demands on mounting and balancing to be carried out in the correct way.
All components must be cleaned thoroughly before installation
Tires and rims must be carefully lubricated
A proper se t pressure must be used
Correct fixings should be used on the balancing machine
If a machine is used for measuring “power variations”, this measurement must be done with the correct tire pressure. Usually 2-2.2 bar.
The WDK-German Rubber Manufacturers Association has developed an instruction for mounting Ultra High Performance and RunFlat tires (RFT).
By following this instruction you can avoid many problems, and keep in mind that there is nothing that distinguishes the classified categories against standard tires,
more than these are more sensitive and more difficult to mount.
Using a high quality lubricant facilitates mounting and helps the tire to get into the correct position more easily. It is an additional cost compared to a universal lubricant, but it is an additional cost well worth the money. The lubricants below are recommended. That is not to say that there are no others on the market that are equal.
2019 STRO data book contains new and older data for over 7000 different tire sizes. In 2019 STRO data book, there have been more than 200 updates. For example, the book contains 40 new passenger car dimensions, 20 new dimensions for heavy vehicles. And all the other chapters are updated with new standard tire sizes. Among the carmanufactures, there are 50 new car models and existing car models have been updated with new tire dimensions.Order
