Drop In Mpg With Winter Tires On Rx350?

[RX350lover]

Do you experience a noticeable drop in mileage when travelling on highways after you have winter tires installed on your RX350? And if yes, how many mpg are you losing?

Thank you.

Rolling resistance of tires varies substantially and doesn't affect only cross-over vehicles like the RX. There is a nice 3-part overview on Tire Rack's website: http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=29
