So does anybody still make rear wheel skirt covers for the 2010+ Prius? I'm planning to get these to install and have a small tire in the rear. Looking at the VW XL1 I saw that it had matched its mm of tread per pound front to rear with a set of staggered tires.
With the weight of the XL1 @ 1753 lb, 45% F bias (@ 788.85 lb) with a 115 mm tire, 55% R bias (@ 964.15 lb) with a 135 mm tire.
This works out to:
Front: 115 mm / 788.85 lb = 0.1458 mm/lb
Rear: 135 mm / 964.15 lb = 0.1400 mm/lb

The prius has a 3042 lb curb weight stock with a f/r (%), 60.2/39.8.
Front: 195 mm / 1831.284 lb = 0.1065 mm/lb
Rear: 195mm / 1210.716 lb = 0.1611 mm/lb

Going for a 195 up front and rear options:

Option 1: 175/65/15 Michelin Energy Saver a/s
Option 2: something small too that will fit on the oem wheel but with the rolling resistance of the infamous re92
The new prius eco has enasaves, so enasaves or energy saver a/s? hmm...
Any Thoughts?
