Yes, my current tires are rated at 3750 lbs per tire at 80psi. I will probably get new tires next spring. FYI I did offload about 1/3 of the water before hitting the road. I just wanted to see what it would be with the full tank. I didn't need that much water for the weekend.
You're 300lbs overweight on each tire. Not good.
Unless you have a 240 gallon fresh tank, 1/3 of your water isn't nearly enough to bring your rear axle weight back down to anywhere near the rear tire limits. You need to shed close to 600lbs.
You absolutely do not want to overload your tires, and you absolutely absolutely do not want to wait until next spring to do something about it.
Tire ratings are one thing nearly everyone here agrees on. It's impossible to argue when the rating is molded right into the sidewall of the tire. They're also responsible for most of your vehicle's control and stability. You can have most anything else in the suspension fail and still maintain control. When a tire shreds, you won't necessarily lose control but you won't necessarily maintain it either...
