So... Wheels!
This is a research post, not a mod, because I have not yet installed anything.
Despite identical powertrain, Auris has different chassis comparing to Prius. So, I cannot blindly apply "best practices" from PriusChat - I need to do my own research.
Factory tyres are 205x55x16, Bridgestone Turanza ER300.
For some reasons, they are extremely heavy, like run-flats. There are several different variants in my size, current setup weights 9.96 kg per corner. While any other tyres including other variants of ER300 are between 8-9 kg. I have sold them already while currently driving winter tyres.
Wheels have size of 16x6.5j, ET 45mm, bolt pattern is 5x114.3mm, center bore is 60.1mm.
Factory wheel weight is 10.0 kg per corner!!! Which is extremely heavy for normal 16in wheels.
Like everyone, I want to buy a set of RPF1
but I will not...
In my size they weight 6.2 kg - cool, I could save 3.8 kg per corner.
1. They are expensive, especially taking into account delivery into my region (no local dealer/importer). May cost up to USD 1500 per set (wheels + delivery).
2. They are wider... still fit factory tires, but I want to gain some aero also. This is a good option for city driving, but not for interstate roads.
