so my last jeep i had some 35 km2s and if i drove through a puddle on the road, maybe 2 inches deep or more, going 30+ i would jerk to the side pretty bad. wondering if anyone else out there has had this same thing with their mud terrains, or if its just the km2 and id be fine with most other m/ts.

thanks!

Any large tire is going to hydroplane some due to the large surface area, but some are definitely worse than others. I'm running trail grapplers and they do good in the rain.

 

I had my old KM's siped which helped but your KM2's should work better than those even. My current Mud Grapplers get a bit dicey in the rain too so I make sure to be on my toes when the roads are wet (which is about 90% of the time here in the PNW.)

 

I have nitto trail grapplers 295/70/17 and they will jerk the wheel a little in puddles but n general handle awesome in the rain.

 

yea, im asking cause yea i was able to handle it but there might always be that time when the puddle is deeper than it looks and when the wife is gonna be driving it she doesnt want to have to deal with it. you say your nittos do good? do you still have to hold on to that steering wheel to not go anywhere or. also a slowing down force is present too that wouldnt happen with the stock goodyears

 

I think you're asking a somewhat goofy question. If you hit a puddle with just the right side of your Jeep at 30mph, the steering wheel is going to want to pull hard right regardless of the tire you've got on. If both your left and right front wheels are traveling at the same velocity, and only the one on the right side encounters additional friction (deep puddle), then yeah, the Jeep is going to want to turn towards the right side, because the left wheel is connected via the vehicle's structure and now wants to keep traveling at the same speed it was before.

If you hit a puddle head on with both front wheels at 30+mph, , you're probably going to encounter a bit of steering loss at minimum while the Jeep hydroplanes on top of the water, and some steering instability depending on the depth of the water at each wheel..

You should always avoid standing water on paved roadways, period. No, that's no fun and I probably sound like a cranky ass, but the obvious consequence is that it could cause you to lose control and the splash or swerving could cause other people to lose control. You're at fault if an accident happens. The other unknown is the depth of the puddle and what's under the water that you can't see. Is it just a stopped up drain? Or is the grate sitting under there on it's side? Is there a grate over the stormdrain at all? Is there a pothole there because an issue with water going under the road? Ya just never know and I've seen it end poorly.

If you can't avoid it, slow way down. Sometimes you can't avoid it and couldn't see it. In that case, let off the gas and hang on!

 

so tell me why i dont feel it nearly as much as my stock jeep all terrain. if at all. cause of the way the water is displaced maybe? the km2 just has some crazy channels in between the lugs. the water cant be pushed outward say like a slick so it forces the tire to hydroplane MUCH easier, the point was to find out of there were any other mts where water wasnt as big an issue guy. thanks anyways

 

He is right. You were right too when you mentioned displacement. Get a thin m/t and you won't feel it as much. The width of the tire is what's battling the water far more than the channels.

 

ahh. whats the stock 32" tire? 10" wide? so another 2.5" makes all the difference. is there a spec that i dont know about that is talkin about how deep the lugs are?

 

Lug depth would be the same as tread depth, and yes the pulling sensation you're describing will increase with tire wear. And also 2.5" in tire width is huge! Remember to multiply that by 4 too!
