I’ve been thinking about the mpg sacrifice associated with going to bigger tires and did some analysis to estimate added fuel cost per month due to declining mpg resulting from larger tires. This is not meant to be definitive, but rather a simple way of assessing the added cost under different scenarios.
See the bar chart...it shows how a loss of 1, 2, 3 mpg etc. due to whatever (e.g., going up to 35s, 37s, towing) increases your monthly gas cost given different miles driven per month (500, 1,000 up to 3,000 per month).
Here are some examples:
1. if you drive 500 miles per month and have an mpg loss of between 1 and 6 mpg due to going up to 35s or 40s or whatever the reason for the mpg loss, the added gas cost will be between $4 (a 1 mpg loss) and $37 (a 6 mpg loss) per month. This assumes a cost per gallon of $2.65.
2. if you drive 3,000 miles per month, then the cost will be between $26 (1 mpg loss) and $221 (6 mpg loss).
Hope this is helpful. I drive 600 miles per month so if I go up to 35s and lose a few mpg the impact will be tolerable.
