Use Your Head
It's all in your mind. Not really, but using your head when driving is very important. When attempting a tough obstacle, think positively. Think about making it. Look at the end, your destination, and aim for that, NOT at something tough in the middle. You'll end up where you look. Every time.
Get In Balance
If you're tired of making repeated trips to the tire shop to have the tires re-balanced (one trail run can throw them out of whack), maybe try adding some ballast to the inside of the tires. We've heard of people using everything from ball bearings to golf balls, but for the best results without lots of trial-and-error testing, you can buy granular or liquid ballast off the shelf at many tire shops or agricultural supply stores.
Stem Tool
For a convenient valve core puller, take an old valve stem and put a core-remover cap on it. To make it more secure, put a drop of Loctite on it before assembling.
Keep Moving
The final tip is obvious, but many forget it. That tip is - DON'T DRIVE IN ONE PLACE! No, we aren't talking about driving in one location, such as Arizona, too much. Think about it.
