I recently jumped into a Fleetwood Flair with the f53 chassis. It was definitely rough.
I did what Timmac did...CHF and tire pressure. Next are the Monroe shocks.
I run all my tires at 80lbs. Notice a small improvement.
Timmac...Is it okay to run 75lbs in front? Can we go that low?
Thanks for your input.
Yes I have the 14 ply G rated tires, one size stronger than the factory tires, when I had my motorhome weighed it was light in front axle and had about 2000 lbs spare carrying weight at 80 psi as to the tires rating, and Hankook AH11 also states the tires can be as low as 70 psi and still carry more weight than my front axle, so I set the fronts at 75 psi almost 3 years ago and no issues except a softer ride in front, I even carry a heat sensor gun to measure temps and the front tires run cooler than the rears that are inflated to 90 psi but I do tow a heavy trailer.
NOTE: Don't go below 80 psi with the 12 ply F rated 19.5 tires that some motorhomes have.

Awesome information. I had no idea about the g rating of tires. I have the G670 g rated 14 ply. Been running them at 80lbs.
