I'm running 27.5" Swampers on the rear of my 2wd Toyota. I don't know what tire pressure to use. My front tires are approx. 26.3" AT's. I am running 40psi in the front and 35psi in the swamers. It seems to sway all over the road. What should the tire pressure be?

Thanks!

 

Use the chalk method.

Make a mark with the chalk all the way across each tire.

Drive for a short distance, a straight line is best.

Note the wear pattern in the chalk. If there is chalk left at the edge the tire is over inflated. Chalk left in the center means it's under-inflated. When the chalk is worn off evenly, the pressure is just right

 

Thanks! Never thought of that! Guess I should give it a shot!
