Wrote this little blurb regarding the issues you are addressing regarding load rating.
It is actually the least understood issue going to almost any plus size in 4x4 tires. We are familiar with how exacting most Raptor owners are... measuring 1/4" difference in fender well gap front to rear, but going from a 6 ply to a 12 ply tire is no problem?????
How do you suppose a Jeep Wrangler rides on 12 ply 35"s?

what is the problem going from 6 - 12 ply? I went from 10 -12 ply but Im still curious.
