What pressures do you run in your tyres?

[Jeff]

I agree with you, but I can also see why they wouldnt. Every inch helps (so they tell me).

I run 5-6psi... 38.5 SX's on 16.5" rims, mechanical double beadlocks. SX's are pretty stiff, but mine are grooved, well worn in, and I have 16.5" rims.

Most rockcrawlers are running bigger rims now (17+ inches), so they don't LOOK to be aired down as much. They also run quite a bit of water in the tires.

With a big tire on a small rim you get alot of bagging, and even sidewall 'ripple'. With the same size tire on a larger rim, at the same pressure, you get much less ripple - and less bagging even - as there is less sidewall.

It's a trade off between pressures, ground clearance, steerability, stability, etc... you have to pick what works best for the weight of your rig, and the terrain, and your driving style.

can i please ask what the point of having water in your tyres is?

[FireTruck]

it's the absolute lowest that you can put weight... lowers the COG, keeps you rubber side down, and helps to mould the tires to the terrain.

Internal beadlocks dont stop you getting shit in the bead. Especially if you go on an offcamber situation in the mud. They only stop the tyre coming off the rim. The pressure in the beadlocks needs to be checked AFTER letting the tyres down as it will slightly decrease. I run about 45psi in them.
