So I just replaced the ****ty dunlops with 175-64-14 general RT43s. The grip has significantly improved in wet, so is the road noise. However, my MPGs have suffered tremendously. I am down to 34 in city and 38 on hwy, from 39 and 44 (70mph). These are non LRR tires, so obviously mpg wont be as good as with dunlops. I have read brand new tires could hurt the fuel economy upto 20% because of deeper tread block. I have thus raised the tire pressure from 35psi to 37.5 psi in all 4 corners to overcome some of the rolling resistance. Any other ideas?
