Re: what gears for a 05 6 speed on 37-13.50 18s
Did you try the math? New tire height divide by old tire height multiplied by current r&p then depending on what's close go with the higher for towing.
I had a Sonoma that I lifted and when I went with the bigger tires went from 3.42's to 4.10's. Then went looking for MPG
stepped back down to 3.73's, what a mistake. Didn't notice any difference in MPG
and couldn't get the rebuilt with added power to seem like it was doing much for towing.
