Another tire pressure post

Iíve always run 80lbs in my tires on my Ď99 Southwind with duallies per cab sticker.
The tires say 120lbs max cold. Is it relatively safe to put another 10-20lbs in? Would it help side sway (which can be significant in winds). I replaced the front shocks with Bilsteins, and it reduced vibrations in the steering wheel, but didnít help sway. Would doing the back shocks help that? Stiffer shocks maybe, or is there another approach to side sway?
GAWR front 7,000lbs Iím at 6,100lbs
GAWR rear 13,500 Iím at 10,400lbs

Thanks guys!

The tires are good up to the sidewall limit , the added pressure may help; could be you'll feel the bumps more though; but for tried and true sway fixes you'll have to do some reading in the Chassis section of the forums .

What chassis is your coach on ? Workhorse ? Ford ?

Replace rear shocks too. Shocks can go bad due to age as well as mileage. Higher pressure will reduce sidewall flex, but that is a normal trait of radial tires.

Do you have a front sway bar and rear sway bar?

I would suggest getting to the root of the problem, do you have sway bars, if so what sort of condition are the bushings in. If you do and they are good, you might need to look into adding a track bar depending on which chassis you have.

I don't think the tires are the problem. Look into other suggestions!

Thanks. I’ll check the sway bar(s) and bushings next.
