Find your GVWR on the door post. The carrying capacity of your tires, has to add up collectively to the GVWR of the truck. however, You'll end up with more than you need.

Actually GVWR has nothing to do with sizing a tire to the trucks axles.
The tire capacity has too meet the highest axle rating which is usually the trucks RAWR
Tire selection
S4.2.2 Tire load limits for multipurpose passenger vehicles, trucks, buses, and trailers.
S4.2.2.1 Except as provided in S4.2.2.2, the sum of the maximum load ratings of the tires fitted to an axle shall not be less than the GAWR of the axle system as specified on the vehicle's certification label required by 49 CFR part 567. If the certification label shows more than one GAWR for the axle system, the sum shall be not less than the GAWR corresponding to the size designation of the tires fitted to the axle."

Make sure the tire has the capacity and the proper load range.
