Have any of you thought about swirching to less stiff tires 19.5s? I'm currently running G rated Hankooks in my signature, but I've found that I haven't used the full capacity of Gs. I'm thinking of switching to Fs.
Will I see any significant difference in ride (unloaded) if I go to Fs? Maybe Es are an option, but I haven't really started looking yet.
BTW, I like the Gs with the camper on, but I drive many more miles without and the ride is quite bumpy on washboard roads unloaded.

I have had F (Yokohama), G (Michelin), and now H (Continental) on my truck. I can't really say I could see any difference with the ride among them. Empty I air down to 75 PSI and loaded 90 PSI. Right now I am empty with 90 PSI and ride is bumpy. I am loading back up Saturday so see no reason to air down.

I'm interested to hear what the responses are.
I moved my Q to another thread so as not to highjack.
Sorry.

There are options besides 19.5's. There are high capacity oversize 18" tires that can handle some heavy rear axle loads. The trade off is that these tires are taller and wider than the stock size tires. There are braking and acceleration performance decreases to consider due to the increased tire diameter and tire/wheel weight, as well as front fender clearance considerations on trucks that do not have enough suspension height to clear the larger tires.
For maximum weight carrying capacity in an E-rated tire in 18" wheel size, the Toyo all terrain is available in 285/75-18E size with 4080 lb weight rating at 80 psi single. This tire is about 35" tall and 11.5" wide and needs to run on an 8 to 10 inch wide wheel with matching weight and pressure rating in order to use the tire to it's full capacity.

There are a few options for 18" to 20" tires with a 4080lb weight rating. The issue is finding a readily available forged wheel with a 4k+ weight rating.

My MH has 19.5" tires that are G range tires now, and I think they actually ride softer than my previous F range tires, so I think it depends more on the mfr. The F's were coopers, ran em at 80 PSI, the G's are Hankooks and run at 90 PSI. But the Coopers seemed to have a much stiffer side wall to them and stiffer ride.

A custom built steel wheel is the route I would go to run those tires. I had to go that route to run my 3750 lb rated 285/75-16E's at full capacity. I had Stockton Wheel make heavy duty welded steel wheels using 8" DOT rim shells and 3/8" flat disc centers to fit my truck. The cost for the pair was no more than a pair of Alcoa aluminum rims. Unfortunately, Stockton Wheel is now out of business. I tried to get some duplicates of those wheels made by another company that also does custom wheel manufacturing but they flaked out and never built the wheels for me. Some day I will go on a hunt for another company who can build me 3 more wheels to match my Stocktons.

I have been on the hunt to find a good set of 18" rims with a high weight capacity. I would like a set with a nice offset. Im currntly running Diamo 8 Karat that are rated for 3800 lbs. I found the 295/70 r18 trail grappler by Nitto that have a 4000lbs at 80 psi. I have a 4" lift so I can easily get these under my truck.
