Tires are less than 5 weeks old and trend is pretty aggressive. It also happens on dry pavement with old and new tires but as pointed out I'm not the only one so I'll try some new shocks, I need some anyways.

Mine does it pretty bad since I put bigger tires on it and being load range E 10 plies its much worse. I'm hoping a shock upgrade will cure it.

Any truck with bigger tires and a straight axle will step sideways through a corner. Rear wheel drive cars and lighter trucks trucks have softer suspensions so you don't feal it as bad. The ony real remedy is irs! It's normal I wouldn't worry about it!

I get it sometimes. I notice it if I'm on the loop to get onto the highway and there's the small bumps from putting it together. My backend tends to jump but that's doing 70mph. But usually it's not to bad.

Before dropping the cash on new shocks, try dropping 5-10psi out of your tires. On high float truck tires you don't need max psi unless you're towing.

My max PSI is 65, I have ran 35 and it was crap. I'm at 40-42 which feel good.

i remember back when my truck was newer it would do that with the stock tires. then i was up in utah working and i was driving down extremely rough roads all the time. at first i could barely go 30 mph through the turns on washboard dirt roads, after a couple months i could go 70 mph and hit potholes through the turns without breaking loose on dirt. after i left there i replaced my struts and put some overload shocks on the back but i think since the leaf springs got a little exercise it keeps it from doing it now.

I'm experiencing the same thing the OP describes and I can tell you that Bilstein 5100's don't get rid of the problem. I just upgraded to those shocks front and back and then put on bigger, more aggressive tires two days ago.

I never had this problem before and now my truck (2010 F150 XLT Scab 4x4) skips/jumps/slides sideways when I hit a bump while cornering. It's worse at higher speeds - like 55-65mph on the freeway while following a curve in the road. We get frost heaves in the pavement here in MN (cracks that rise up to create bumps) and it's a very uncomfortable feeling to momentarily lose control like that. I'm paranoid about this for the upcoming winter when the pavement is snowy/icy.

I set the front shocks at the highest setting (2.25" lift/level), and went from 32" diameter stock wheels to 34.5" (11" section width to 12.5"). They are Kanati Trail Hog tires (10 ply AT's) - 315/70R17. So far I've tried them at 40 & 50 psi (max = 65).

I understand that going to a heavier-duty tire will have some drawbacks, but this one seems beyond safe. If anyone has any explanations or suggestions (other than getting rid of my new wheels) I'd love to hear 'em. Thanks.

Get a pair of these for the back end. They are considerably better than the stockers. You can install them in 10 minutes with a couple of wrenches. Don't even have to lift the truck to do so.
