What causes a Jeep to pull when going through puddles on the street?

I've noticed, since I've lifted and put larger tires that my Jeep really pulls when I hit puddles, more so that when it was stock. At slow street speeds, it's not a problem, but at highway speeds, it's almost pulled me off the road. Is there anyway to correct this?

You'll need to adjust your alignment after the lift. Specifically, the Toe. It will have changed, and makes a big difference in overall stability. Secondly, depending on the tire tread design, a larger/wider tire is going to be more prone to pulling as it hits a deep puddle. Nature of the beast.

The toe alignment on a JK doesn't need to be messed with, most likely.

All cars pull when they hit large puddles at speed.

Correct caster makes the Jeep feel as stable as it did when stock.

Does your lift have control arm drop brackets or adjustable arms?

I don't think I've ever hit a puddle like that at highway speed, but a skinny tire is going to slice through water way better than a fat one. If you're running 12.5's, my suggestion is to either slow down or avoid the puddle.

You have a bigger tire with more resistance and that's all there is to it. Bigger wider tire is not going to slice through puddles like narrow tires. The lift has nothing to do with it.

On a side note. Installing a lift does not affect the toe alignment no matter how high you go. However, if the toe was out before the lift, the difference in caster after the lift may make the out of line toe adjustment more apparent.

My first thought was hydroplaning..which is to say that the tires don't dissipate the water fast enough to keep traction. Are your tires "siped"?

I had this issue with my '71 K5 years ago, on 33" Bridgestone Duelers, and I remember the pucker factor!!

Wider tires = more drag/resistance. Not rocket science.
However proper alignment will help, and proper tire pressure will make a huge difference. Tire psi shouldn't necessarily be the same all year. An under inflated tired will trap water under the center of the tread and hydroplane more. A little more pressure will round out the tread and help force the water to the outside edges.
Also worth noting that some tires and tread patterns just suck in water.

NOT on a JK. On a Tj when you go up it changes the toe, so does just cycling the suspension. On a JK the Tie rod is separate from the drag, You can lift a JK 20,000 feet and the toe will not change.

Now geometry changes, yes.

This. Plus, as most of us do when lifting, you probably put a large mud or aggressive All terrain tire on. These tires tend to have larger tread blocks, and don't easily disperse water at high speed.

I usually drive 50mph during these storms because of this issue. The last one was so bad, I got off the highway and took the local streets because it would be unsafe for me to drive any slower on the highway.

I concur.

Proper alignment specs including a bit more Caster will improve your directional stability with the larger tires. Even stock tires pull to one side when you hit water because usually puddles are perfectly symmetric across both front tires therefore they create induce towards one side or the other. A slight increase in Caster angle will increase the front tires tendency to want to go straight. The correct steering stabilizer will dampen the pull but not eliminate it.
