Only 2 tire choices for stock size 265/60/20 in P metric - what fits stock truck?

So from the factory my 1794 has 265/60r20. There are only 2 tire choices that exist in that size that are not LT tires.

What size are you running on a stock truck that is more common so I have more selection and better choices? I want to keep the rims and not modify the suspension.

 

I understand wanting to keep the rims, but this is a byproduct of the 20" stock rims.... that, and I've curbed them twice due to no sidewall on the tires. Going to 18"s for this reason and the tires prices and availability in that size will cover the cost of rims after 2 sets of tires.

Still frustrated the "Off Road" model came with 20", my 3rd Gen Tacoma OR came with 16".

 

285/55/20 is pretty darn close

 

Michelin does make the Defender LTX (P rated) and the Defender LTX Platinum (E rated). I went in to Costco Tires last week to ask their tech his recommendations. I also asked his thoughts on getting the Defender LTX in 275/60R20. He looked in his computer and said that he can get the Michelins in 265/60R20. Just have to give him a few days to get it from the main warehouse but it was in stock.
