Just recently changed my oem MXM4 on my 13 TL to the A/S3+. Same size and speed ratings.

How much of an mpg loss have you encountered for those who have changed to A/S3+?

Thanks.

Highly unlikely you'll even be able to measure a difference in fuel economy.

Been driving the A/S 3+ for a little over a month now. From my driving, I’m getting 30-45 miles less driving before having to fill up. About 2-3 mpg loss.

I had reset the trip indicator each fill up to see what the mileage is to use as a measurement gauge.

I do notice that rolling resistance is noticeable when comparing it to when driving with the oem MXM4.

Two comments:

• New tires have higher rolling resistance than when they are well worn; nature of the beast.
• This time of year, what with winter blends of fuel and colder air temperatures, it is MUCH more likely your perceived fuel economy losses are related to the season and not the new tires.

I know with the A/S 2's on my 760 I lost 2 MPG right away over the worn PS2's.
