Need help on Tire Calibration..
Hello Everyone in WA,
I upgraded my 17 inch stock tires and rims (LT 265 70 R17) to 18 inch tires and rims (LT 275 70 R18). I've notice that I have lost 2 miles per gallon when I changed tires. I know if I change to a 275 65 R18 I could get close to my original tires and mileage. The tires are fairly new and I don't want to wait till I change them. Gas is getting high.
I wanted to know if anyone has a Tirepaq calibration unit for a ford F250 that could help me out. I don't want to purchase a unit for a one time calibration. I know I will keep this size tire and rim for my truck. Again I was just hoping if someone could just change infomation on my truck and let me know how much you will charge.
I could meet in the Kirkland, Redmond, Bellevue, Woodinville or Seattle.
Could anyone help me out.
Thanks,

I would guess that you aren't really getting worse gas mileage by swapping tires, especially to larger ones. What is happening is you're not registering as many miles as you did previously with shorter tires, so your odometer isn't registering all the miles you're driving. You need a speedometer calibration so it reads correctly. Either way, it's not affecting your actual fuel consumption.
On the plus side, you'll have fewer miles on it showing, at trade in time. lol
