Mini Buggy Tire and Wheel Upgrade

Our "Terra Tamer" buggy was built by my wife and I in our garage a few years ago and it's been a great project and a blast to drive. We've made a view changes over the years making small design changes here and there in an attempt to improve reliability and/or performance. During our last trip we decided to make a few more changes to suit the type of driving we do most often with the buggy. First of all we decided to gear it down a bit more swapping in a 60 tooth sprocket instead of the 54. Next we decided that the rear width might be better a bit narrower for some of the narrow canyons and trails that we do. Having a narrower tire would also reduce weight and stress on the rear axle components. After searching around we decided to go from an 8" x 10"wide wheel to a 10" x 8"wide wheel, and from a 22"x11"wide tire to a 22"x8" wide tire. We reduced weight even further by getting aluminum wheels and a tire designed to be light making a tire and wheel package that weighs about half of the old setup. This reduction in unsprung and rotational weight along with the lower gears should give a little power boost and make it more maneuverable. The pictures below show before and after taking about 6 inches off the total width. The width in the rear is now about 51.5", just over the max width for forest service trails(50"max), so it should be just fine for the times we do go on these types of trails..assuming no one is running around with a tape measure. Stay tuned as we take it out next week for a full test..in the meantime check out these pics. I'm really happy with the way it looks. The wheels can be reversed for either 3" or 5" backspacing. We chose to run them with the shallow portion of the wheel out in order to take advantage of the decreased width, but they could easily be reversed for more stability. The valve stem is hidden behind the wheel this way, but is still easily accessed for filling the tire etc. The wheels are Douglas .160, and the tires are ITP Mud Lite AT's.
