First of all I called several tire places including Goodyear locally and non would consider changing the tire size from oem! My normal tire place has free balance and rotating recommended the Cooper cs4 touring. Anybody that has used this tire for a period of time and can please give your feedback? Thanks
I put on the Cooper's CS4 about a month ago and now have about 5000 miles on them but my mileage really dropped after I put them on!!!!!!!! I was getting 53 to 58 pretty consistantly on the road and now I struggle to get 48!!!!!!!!!!!
I put them on my wife 2009 prius a month ago. She said it ride better than the stock and very quiet. I got them for buy 3 and get one free at $85.00 per tire with $50 rebate. The prius still averaging 50 MPH. I recommended if you get it for $85.00 or less.
I emailed Cooper tires to determine if the CS4 was considered a (LRR) tires. They replied stating the CS4 is not a LRR tire. This could be a factor to your drop in MPG. The Cooper GFE is considered their (LRR) tire.
