Check your tire pressure!!!

Instead of 33 per window sticker, you can have up to 37-38psi because of bigger/heavier tires. Dealer recommended to me after I got the tire presure warning light lit up on the panel with 44psi for 3 weeks after ko3 installed. 38 psi helps soften driving/ floating

This does not make sense. Bigger and heavier tires to not inherently require more PSI. If anything, they may require less air pressure if they are E-Rated tires with thicker sidewalls.

The only way to know for sure what PSI to run is to do a chalk test on the tires. Googling "chalk test tires" will turn up a ton of tutorials.
