There's not a lot of difference in GVWR between the 5 lug vs 6 lug.
4600 on RC, 4700 on the X-Runner, and 4900 on the AC and DC.
5250 on AC, 5350 on DC
5100 for RC, 5350 for AC, and 5450 for DC
Max is 5450 for any of them, and only 550lbs difference between the Access cab 5-lug and the 4x4 DC.
Hell... that's not much over the load rating of my motorcycle's tires.
5-Lug stock tires (215/70-15) have a load rating of 98. That's 1653lbs per tire. That's 3300 per axle.
BFG RT T/A and Bridgestone Duelers are rated 109... 2271 per tire, 4542 per axle.
There are plenty of P-rated tires of the proper size for the Prerunner/4x4 that carry the 109 load index. Scanning Tirerack
, it looks like 109 is the minimum for the 245's.
Tire shop employee was feeding you a line because he didn't want to sell you the cheaper tires. These aren't 3/4 ton HD fullsize trucks.
Tundra Crewmax comes with tires rated 112... 2484 per tire, 4968 per axle.
GVWR is 7200lbs.
