When installing oversize tires on your vehicle, you’ll notice that you’ll lose low-end power when towing, taking off from a stop or even on the trail. To regain this power, you’ll need to re-gear your differentials. The formula to figure out ideal gear ratio is stock tire size divided by the stock gear ratio.
This should be equal to your new tire size divided by your new gear ratio. However, this doesn’t account for extra rotating mass of the tire, just the dimensions.
Going strictly by this formula works well for street driven trucks without heavy aftermarket accessories. If you’re looking to get more torque for carrying heavy loads, towing, or if you spend a lot of time on the trail, you’ll want to pick a ratio that is deeper (numerically higher) by one or two available ratios than what the formula suggests. This typically ends up being between 5% and 15% deeper.

It’s officially been 6 years since Rugged Rocks had it’s first customer, and being that it was an online sale I didn’t get to pin my $20 bill on the wall as many brick and mortar shops do. But even without the good luck of the first $20, Rugged Rocks is still here. Although day to day, I run Rugged Rocks by myself, I couldn’t have gotten this far without the great support of some key people in the Nissan community who have spread the word of this company. Some went so far as to get articles in some popular off road magazines! I send out a huge Thanks out to those that have helped keep Rugged Rocks going over the years.

Happy New Year from Rugged Rocks! We’re kicking off 2011 after a move to South Lake Tahoe, CA over the holidays! After getting a few feet of snow we’re still getting settled in and back into our regular routine of doing business. Due to the recent storms, we’ve had a delay in getting consistent phone and internet services up and running, but it’s expected that we’ll have the issues worked out in the next week or so. Besides the issues with utilities, we’re really looking forward to a killer 2011 being that we’ve got great new products coming right around the corner. We’re now just a stones throw away from some of the greatest wheeling in the country which includes but isn’t limited to the famous Rubicon Trail. Not only does this give us a place to play, but a great area to test new products.
