Tundra tire squirm

got a new 2019 tundra with Michelin LTX AT2 on them. I put a rear seat bar on it to help with body roll at highway speeds 60-80 mph. The truck still feels like it’s drifting or not planted. It almost feels light/floating. The steering fees loose. Is this tire squirm that I hear about with these tires? Should I up trait pressure in the tires to stabilize it more?

 

It was at 33 f/35r. I just bumped them up a bit. I havent ran c rated tires in a long time. Usually have e rated at/mt tires 35”-37’s and those are expected to be rough at highway. So not use to light weight stockers. Just wasn’t sure in there is a secret spot for the tundras. I ran my fj tire pressure higher to stiffen up the ride a bit.

 

Awesome. Thanks dude.

 

Try keeping the front and rear tires the same air pressure unless you are hauling weight. The factory pressure on the door states the rear pressure is higher then front. The sway bar causes oversteer. Keeping tire pressure the the same will create a little less oversteer which will feels more stable. I keep mine 32f 32r. I have the same tires and sway bar and it feels much better. Hope this helps.

 

What's your caster and toe at? Low caster or no toe can cause that.

 

thanks the air pressure def helped I upped my to 40f 40r feels better
