I have 4 fairly new 27x8.50x14 General Grabber AT tires that I want to trade for slightly smaller tires
These have less that 1,000 miles on than and are in near new condition. I am only driving a mile or two a day and they are killing my MPG.
I am in Salem Oregon and can meet locally
Thx

Re: Trade me tires…
I’m sure you thought of this, but keep in mind that having different sized tires on will make logging mileage really difficult. Your speed is off, and hence, trip logger is off.

Re: Trade me tires…
You're correct that non-stock tire size affects tracking of mileage, but it's not hard at all. You just use a tire size calculator like this onePhatcat wrote: Sun Apr 06, 2025 7:23 pm I’m sure you thought of this, but keep in mind that having different sized tires on will make logging mileage really difficult.

to figure out the percentage of difference (in this case, the big tires are almost 20% taller than stock). Then when you fuel up, you take the trip meter reading -- let's say it reads 200 miles -- and add 20% to that, which would be 240 miles. Then you do the usual miles divided by gallons to figure out MPG.
