Ok, I need help. I have a Ford Escape that we use as our main caving vehicle due to great gas mileage. Due to age, miles, and need for stronger sidewalls and better traction, we traded our old tires for new. Love them, but because bigger, noticed huge drop in gas mileage at same speeds used to traveling, and I seem to be staying up with or passing everyone!!
Old = P235/70R16 normal street tires New = LT245/75R16 E Toyo OPAT OWL 120Q Don't want a speeding ticket, and need my good mpg back, or close to it. Can anyone tell me how much to decrease my speed, and if the reduction is the same for all speeds? If not the same, how much decrease at what increments? I believe my old tires were 28" diameter (spare is that) with 7.33' circumference, and new are 30" with 7.85' circumference. I have to believe there are more than enough math wiz/ tire savvy folks out there to get me some answers, but if I am asking the impossible, tell me. I do have a tachometer as well as a speedometer if that helps. For us, mpg means a lot due to cost of gas, and determines how many trips we make. I would really appreciate any help anyone can give me.
