GEN 2 KO2 Tyre pressures on snow on dirt

[Sun Ra]

I'm using slippery in packed or low snow on dirt roads, and deep snow when there's 8" or more. Both tend to slide out corners at low speed, whether on the power or off.

Are you guys lowering your tyre pressures? I'm at 38 all 4. Thanks

Yes, you should. Lowering tire pressures increase contact patch area. The main reason not to do it is that at high speeds (above 50) the constant flexing can create heat in the tire. In the winter, that is not too much of a problem unless you are going hundreds of miles. You can go from 15 to 32 psi depending on how much pavement you will be on and how fast you are going to go. Experiment with it and you will see the difference. You won't hurt the tire, and you won't blow a bead.

Thanks. It's working. I'm finding it impossible to find a real winter compound tyre.

Air down to 28-30 psi

air down and youll also notice is you can get into fresh powder that youll have a ton more traction, the tires arent simply on compacted snow which is now ice.

32 front 28 rear. You can still run on pavement with this pressure, 55 mph etc.

Nokian hakkapelitta lt3’s are winter compound tires that work on the raptor. I’ve run the previous version (lt2) and they’re excellent.

What the hell is in that x-ray in your avatar?? Someone put a baseball up their pooper??

Basketball in the pooper!? It’s a pool ball [emoji23][emoji23]
14 ball to be exact.
Anesthesia I’m assuming? Roc rocks!

Offroad I find 28-30 is a great all around tire pressure for washboard, bumps, some crawling, and some higher speeds.

24-25 for limited high speed days and better traction and bump absorption. You lose a little clearance though, so it depends on what is more important. I find it a little mushy for higher speed fire roads at this pressure. Nothing terrible, but not a preference.

15-24 for sand, mud, snow. If you are just doing deep sand or deep snow, lotsa guys will run lower than 15 no problem at all and also get much better performance. I haven't encountered those conditions as the 24 has taken me around snowy mountains (but not on top of deep powder where the 10 psi might be much better).

If I have a mix of dirt roads, pavement then 32-34 takes the edge off and is comfortable for cruising. Normally I'd run 37 for highway and 35 or 36 around town.

None of this is an exact science so just some targets to shoot for or for context.
