Greetings all.Here is a picture of my rig courtesy of google on I84 in the Columbia Gorge.I have a 99 F350 2WD with V10 engine. The tires are almost 6 yearsold. Currently Hankook 265/75/16E which have been good tires.I don't put a lot of miles on the tires as I just use the truck for camping, hauling firewood and other hauling around town. I put about 3k miles per year tops. But its time to think about replacing them.Recently weighed my rig on a camping trip and gotFront 3800Rear 6500Total 10300GVWR on my truck is 9900Front GAWR 4400Rear GAWR 6830When I take my daughter and her stuff camping with me the rear weight goes up right to the max. (6800)How safe is my vehicle? Note: I carried the same camper on my 1990 F250HD for 15 years without mishap.Looking for options on new tires to increase the safety margin.I see that 285/75r16 tires can go up to 3750 lbs but I can't find out what my current rims can handle.I am willing to go to 19.5/vision tires/wheels but what about brake upgrades and spare tire?Suggestions anyone? Thanks for your inputs.

Thanks for your inputs.Get some OE steelies from a 1 ton and the 285 rated at 3750 you'll be all set. That's what we did and have been running Nitto DG for 2 seasons now. Very pleased.Good luck, BillEdit; I see you're already running a 1 ton. Are they steelies?

Axle can take some extra load, but what is your tires rating?I remember having 7300lb on F250 rear taking some gravel, but I bought Discoverer's tires that had the highest ratings in the size. I had Hancock in 19.5" size on my F450 and after over 80k they still had good tread, but hauling heavy had a blow out, so eventually had to replace the rest of them even with good tread. I remember they were close to 10 years. 6 years is not much for truck tires if they are keep in shade, but check them for cracks and if in doubt, take them to reputable shop for inspection.

That wheel is an OEM F81Z1007AA and they put them on the f550's.I dont see an issue... I think they were the same width and all.Whats the tire pressure on a 1999 f 550? I think they were an F ratinghttp://www.wheelsandcaps.com/p-20374-aluminum-alloy-wheel-rim-16x7-3407.aspx

I would def upgrade the tires. Looks like the wheels are OK.

I don't see a problem with the current tires rating IF you are taking care and not driving like a speed demon down the road. Just stick with a quality tire.

After all, they have been serving you well and did so on the previous truck too.
