Where to buy tires

[Grit dog]

The 121 load index (load range E) is plenty heavy for a 3/4 ton pickup. I sell tires and have never seen anything heavier (load range F or G) on anything up to a 1 ton. If more load capacity is needed, that is what dual rear wheels are for and every 1 ton dually I have ever seen comes with load range E (10 ply equivalent) tires. Heck, my '78 P30 motorhome originally came with 7.50-16's in 8 ply (load range D). Not sure why you would need something with a load range more than E on a pickup?

Huh?
Suit yourself, but me and the thousands of others with srw HD pickups would beg to differ. 121 load index tires are no where near even the rated rear axle loads of all newer HD pickups.
Half the reason very few of them come with 17” wheels anymore and have 18&20” wheels with much higher load rating tires.

And Load Range E isn’t just one load index….
