Thanks for getting on board guys (n dolls?) I'm glad some good tips are coming through
I'm off at a tangent from tyres sorry.....a bit about tackling inclines :
Some of this comes from my trials riding (not Trail, Enduro - Trials!)
Not quite as relevant on the way up with a 4x4 but definitely on the way down !
Down: Usually the idea is L1 (low first gear) and let engine breaking bring you down. There is one danger though. Especially in a vehicle. That is if you find you are slipping. Especially if you find the back end coming round on you ! If you do feel the back end coming round at all. I suggest one of the following.
1/ Dip the clutch - this lets you run ahead and straighten up, feed the clutch back in slowly. The problem with this is L1 may be too low a gear now - So try and grab a higher one.
2/ If you think there is any danger of slipping, start in a higher gear, L2/L3
If I feel the back end coming round at all, or starting to slide I will do something most people still find counter intuitive - Immediately Boot It ! Really, get some quick speed up.
You do not want to risk a roll in a vehicle. Now, usually your slope is easing out onto an area of runoff. So swap a potential rollover, into a question of how to slow down when you are at the bottom. At the worst you will ding a tree !
Now I realise there is an argument that hurtling downhill, you may strike other ruts or rocks that may slew you or flip you. Well. You gotta check the section before you go down. Try and identify the best line. Try and identify the danger area in advance. Tell yourself "I will probably be in trouble at this bit - What will happen and what line do I take when it goes wrong......?"
Going up : well not a lot to say really. Ever rolled backward on a motorcycle/quad bike and hit the brakes? So same thing in a way applies in a Landy. If you feel the nose come up - dip the clutch. If you start sliding backwards..... well either find reverse (tricky) or dip and feed the clutch back in. You might manage to actually stop on the slope. Giving you time to select reverse. Then find out how good you are reversing down a scary slope ! If you ever feel tempted to hit the brake - you had better be as gentle as a little lamb.
Getting up: In trials the idea is to have your closing speed/acceleration as close as you can to allow momentum alone to get you up. With just judicial use of the throttle to find grip. A higher gear is wanted for torque. a low gear means you will spin the wheels and instantly lose momentum. Of course the usual danger applies if you are firing up a rutty slope which may stick a rock out and flip you. So, again, observation observation.
This technique is not always possible in a Landy, but I try and get as much closing speed as I can. If I am not going to get speed - then L1 is as good as anything I seldom use second. If I can't get up in low third or fourth. (sometimes even high box comes into play) Then why not just crawl up in low first ?
That's about it really - some bones of contention I'm sure
