A 8% range hit with new tires - beware! I have a RWD LR with the 18" wheels AERO covers. The factory Michelin Primacy MXM4 gave great range as our watts/mile averaged about 245 for the first 33,000 miles. Then I got new tires Michelin Cross Climate + which had great ratings and the more aggressive tread looked like it would be better for the snow. They make the car feel even more planted, BUT my watts/mile had jumped 10% on the same long drive under the same weather conditions. So 300 miles now become 276. The Primacy MXM4 is rated as a Green X, where the Cross Climate is not.
