Default Safe water crossing

I was wondering how deep of water can a stock JK cross through safely? If you add a lift and bigger tires, does it increase the amount you can cross?

19" according to Jeep. yes bigger tires would mean more clearence and deeper water, but people on here have also hydrolocked in less... Depends on how you do it.

I would think anything deeper than the height of your tires would be asking for trouble ... that is about how high the breather tubes are ...

If you have a manual, don't press the clutch in deep water. NEVER.

If the engine stop, you can start it (in deep water) without pressing the clutch (if you are in 4 lo)

Per the manual, 9 inches for flowing water, 20 inches for standing water...

Flowing Water
If the water is swift flowing and rising (as in storm run-off) avoid crossing until the water level recedes and/or the flow rate is reduced. If you must cross flowing water avoid depths in excess of 9 inches. The flowing water can erode the streambed causing your vehicle to sink into deeper water. Determine exit point(s) that are downstream of your entry point to allow for drifting.

Standing Water
Avoid driving in standing water deeper than 20 inches, and reduce speed appropriately to minimize wave effects. Maximum speed in 20 inches of water is less than 5 mph (8 km/h).

Since the owners manual is not model specific those are safe numbers for a base model with 16" wheels and 29" tires.

The middle was about as deep as my 33's

In still water, if the bow wave is any higher than the bottom of your head lights, you will be running out of air

In flowing water the bow wave should be no higher than your tires.

Its a funny feeling in deep water; remember the jeep will want to float and the tires do Not have the same traction as on dry land.

my owner's manual says that "This vehicle is capable of crossing through water at a depth of 30 inches (76 cm) at speeds no greater than 5 mph (8 km/h). Water ingestion can occur causing damage to your vehicle. "

Are they saying that it can go through 30" but if you do some damage can occur?
