GVWR, AXLE Ratings, and Tire Load Range???

A few questions regarding these topics.....I will be replacing tires this weekend and ran across developed these questions as I was tire shopping/researching.

SPECS

The OEM manufacturer sticker on front left side of my Toyhauler indicates:

GVWR of 13000#
Axle Rating of 6000# per axle
Tire size of 235/80/16D (3000# rating each)

Questions:

1. How can there be a 13000# GVWR if 2 axles and 4 tires are rated at 12000#? What about the missing 1000#?

2. Is there a problem if I replace tires with 235/80/16 E rated with 3420# rating?

Thanks!

#1; Tongue Weight
#2: No problem.. as stated above, gives you some margin, which is fine/good.

You will have at least 1.5k of hitch wt, so axles/tires are good at 13K GVW. No problem upgrading the tires to E rating, just remember to get that additional capacity, they will need 80 psi, as shown on the sidewall.

Re: #1 - The remaining weight is carried by your truck via the hitch.

Re: #2 - Not a problem, and I think that is a very good idea since it gives you an additional 1680 pounds of safety margin. (Makes it less likely that you will experience a blowout.)
