looking at the table, your tire is rated 4080lb at 80psi (max), 3000lb at 50psi, 2525lb at 40psi.

 

I'm running the 35" Ridge Grappler. I had some older 37" BFGs on it for about week but pulled them off after seeing i couldn't park in one garage at a client's office.
The 35's, while they look small, offer plenty of small bump isolation and feel good overall.

 

 

Weird, you'd think they wouldn't tell you basically "Hey, choose any wheel from 17" up to 20""
I drove on both and felt like the 17" was much better given all the extra sidewall but not everyone is as sensitive.

 

I am just confused in how it feels a little stiffer than the factory setup with the same wheels and tires

 

No what i'm saying is i drove the Commuter with my factory 20's for a few weeks before adding my Methods with 37's then 35's...both on a 17" in wheel. I felt like both tires on the 17" wheel made the most comfort difference around town. Dont get me wrong, i think the Carli springs up front and the shocks are miles better than factory but the addition of more sidewall helped on the awful Texas roads.

 

 

I have had pretty much the same experience with my commuter with add a packs. I pulled a bds leveling kit with bds fox shocks to install the commuter and I honestly cannot tell any difference from the BDS to the commuter.

 

Interesting how we've got the same setup, 4.5 backcountry with radius arms, full deavers, but have a different perspective on the ride. The stock F350 was bone jarring, stiff, with poor bump compliance from the factory. But it's designed to haul and tow, not designed as a desert speed running truck. My prior trucks were a '14 then a '17 Raptor, decent out the box for running desert whoops and like a big cushy barcalounger on the road, but no payload to speak of. Went full Carli after about 2k miles stock on the F350, totally changed the ride. Smoother on pavement, better bump compliance, and way more comfortable ride than stock. Night and day difference, in my opinion. I'm running 20s and I'm sure 17/18's would be more compliant, but I'm happy with the ride on and off road with the 20s - had to go 20s to fit the Wilwood TX6Rs. The Carli system does great out here running in the deserts and dunes in Vegas and in Cali at speed, which is what it was designed to do. Yes, payload takes a beating, no sway bar in the rear so yes more body roll, but it's all a tradeoff. So, in contrast, I would recommend getting this lift for a dramatic improvement in road ride and an even greater improvement in off road ride; it is far better than the stock 350 on ANY road in my experience.

It's not ideal, however, to spend the kind of money on a Carli system and NOT get the ride you anticipated. Perhaps going to 17/18 would be the ticket to a better ride.
