This powerpoint shows how you can increase your cars efficiency with aerodynamic wheels and correctly selected tires. At the moment I am developing next generation wheel and tire combination for electric vehicles that will boost range about 10% on all vehicles and make them much more silent. Sample car shown is Tesla Model Y SR where estimated boost in efficiency is about 16%. Most comes from much better rolling resistance as the car is heavy and has C rated tires. but also aerodynamic drag reduction is very important part of the totalsavings. Purpose is to show how you can tweak out more range from your car if you know what to improve.

• Testing new solutions since 2008
• TuneCovers 2013 fastened with Ziptie-
plugs
• Glued covers 2016-
• Own wheel and tire TBD

3. Tuneko and Fuchsfelge
Mini 5½J x 15, ET46 4.9kg wheels with 1mm thick glued aluminum blocking plates

4. Recipe for
efficient wheel
Lightweight for agility and less
rotating and unsprung mass
Minimal cooling holes for better
aerodynamics
Flat or little bit convex for
aerodynamics
Max tire stretch for aerodynamics
and drivability
195mm tire  7” wide wheel

5. Tuneko one size fits
