Well, those gears with those tires make for a pretty slow accelerating truck (at any speed). If you want more acceleration, a higher gear ratio is certainly the way to get it. AND, if you tow much, I'd say you are badly undergeared, which probably puts more strain on your transmission.

BUT, you have a 4x4, which means you need to regear both the front and the rear. This is not cheap, but I don't have any figures to quote you. It would be less expensive to return to your OEM tire size, I think.

What were your OEM tires? We could use the gear ratio calculator to figure out a suitable replacement gearing to get you back to what you had at stock. And, the next size up from that would give even better pulling power probably.
