Driving in teaming rain and really bad lightening.

I live in the lightening capitol of the world and everyday we have really bad thunderstorms during the summer months. I am an Auto Consultant, my own business, I had to drive 25miles to do a car deal on Fri. I had 275x70x18's put on my 10th Anniversary and if I hit any puddles or pools of water, it feels like I am going to lose control of the Jeep. I am used to driving my BMW X3 all wheel drive. I have been in the car business 33 yrs and actually didn't know I could drive at higher speeds in 4wd. What a world of difference in handling in the rain the 4wd made. So if you are ever in bad rains just put it in 4wd and it's a lot safer.

Big diff between 4wd and awd. Straight line, no prob, curves can be an issue... Also t-case is not designed for continual high speed 4wd.

It feels like you are going to lose control because you have a rear wheel drive, short wheel base vehicle. Your Jeep isn't meant to run on the highway in 4WD. As others have stated, there is a HUGE difference between a 4WD vehicle and a AWD vehicle. Take a curve in 4WD in the rain.....and you might find yourself in a ditch because you are forcing one wheel to break traction.

Snow and ice is a different story. I drive at speed in 4wd on our slick winter roads, but the tires are allowed to slip.

What type of consulting do you do?

which tires did you put on our 10A? Which tires are on the BMW? Tires can make a big difference in hydroplaning than anything else, how much water can the tires move and what grip do they provide in the wet.

Disagree with all of the above. The difference that actually matters in the rain are the tires. 4WD means diddly if your tires aren't made for rain (ie any MT). Get proper tires for the type of driving you do. Running an MT in an area with tons of rain on a mostly street driven vehicle is pretty dumb, as you are putting yourself in danger for the sake of looking good. You do not need to put a wrangler into 4WD for rain, ever. It does plenty fine in 2wd provided you have proper rubber. If you do have normal tires, and still feel like you are going to lose control, slow down.

One, if your gonna brag about being the capital of something, please spell it right.

If you are going fast enough to think you will lose control when hitting a puddle. Slow down.

Also,

Previously, Florida was considered to be the lightning capital of the world. However, NASA released a study based on information from the Tropical Rainfall Measurement Mission Satellite that showed Rwanda, Africa is the true lightning capital of the world. It receives nearly 2.5 times as many lightning strikes as Florida.

You shouldn't be to surprised, lots of people can't even change a tire much less understand how a vehicle works. Most people could care less as long as they can just put gas in it and it goes.

Excuse me!!!! I have been in the car bus for 33 yrs and I do understand how things work and I have owned probably 50 some cars,because I can, all kinds, all shapes, all configurations and I had a very very successful selling career for a long time. That's unusual for a FEMALE!!!!!!!! I had to know my products and how things worked.

I didn't notice what surf's top speed was while in 4WD. If it was under about 45 and the roads were really awash with hydroplaning type surface water, 4WD may have been an OK choice. Without seeing the actual conditions, I'm not going to guess that the OP did something wrong. In the situation, it may have been brilliant. We can't really know, IMHO.

Thank you Bill and I did go 70mph and yes it was raining hard all day and the roads were flooded. I understand the short wheel base and rear wheel drive and the larger wheels and tires but it was scarey when I felt like I was going to lose control.

Doesn't matter what tires you have or what vehicle you are driving... driving at 70 MPH in the heavy rain is not something I would do...
You stand a good chance of finding yourself backwards in oncoming traffice, down in a ditch or even worse becoming one with a immovable object.... JMHO

I can't find a word about maximum speed in 4-HI in my 2012 Owners Manual. It says 25 MPH is max in 4-LO, but just says this about 4-HI:

But, I would think 70 was a bit excessive in the conditions you described!

One of my favorite attributes of the Wrangler is that I feel no need to speed... 60 on the highway is good for me. I'd usually rather drive my Jeep than get wherever I'm going in a big hurry....

In the OP defense, I did look it up and the owners manual online did say 4wd hi speed is the maximum safe speed. But not I I. A pt 4wd. I know how pt 4wd works and either could be an ugly crash, or expensive breakdown.

When it's raining super hard and I'm on hwy roads, I'll pop it into 4wd... I'd does help with hydroplaning, if it starts I throttle through it. Hydroplaning can happen when the wheels with no power spin slower causing a surfing effect. I've driven through some deep laying water in 4wd and the tires cut right through. Hwy curves seem ok in 4wd but when I'm slowing and sharp turns as well as stop and go turning, I pop it out of 4wd. It is not good on the drive trane to turn on asphalt. If you can feel resistance, you are doing damage. I like jeep 4wd on-the-fly for just those purposes. My 8th jeep and been driving like this for a long time with no problems.

You are incorrect here. When in 4hi you can drive the Jeep at any speed you normally would. You can also make turns on roads as well. You might start getting the lurching of the Jeep if you are doing right hand turns at a light, but if following the curves of a road its completely safe to stay in 4wd even on dry pavement. There is simply not enough differential between the front and rear of Jeep for it to notice.

I have driven in patchy conditions on both a XJ and my JK. Never had a problem with staying in 4hi if the road suddenly goes dry for a little bit.

In the owners manual they recommend not switching into 4hi above I think 40 MPH but I have switched into it doing 50/60 before with no ill affects.


To the OP, the wider the tires you run the more you will get a pulling from hitting deep spots of water. Try hitting a patch in the road with 315's
