I have a 2006 F250 Lariat 6.0L TV. I needed tires and the shop recommended the following;
LT245/75R17 by Michelin

I bought 4 tires, had them mounted, and drove away. When I got home, I noticed a difference in size. The placard on the vehicle door calls for;
LT265/70R17

Are these Michelins acceptable since they are a different size than the placard states? I don't want to pitch a fit unless it is important, but did I spend a lot of money on a sub-standard tire? Also, are there legal ramifications for the shop, or for me, or should I just drive on?

on tire rack they say either of those sizes could be OEM tires for your year...
bet it has something to do with GVWR and GAWR for towing...

were the 265's already on your truck and original tires?
maybe the previous swap got the wrong ones then

See what 'should' be on your truck based on your equipment...

and go to tire rack for the recommended tires
Stock tires
and
The new tires

Compare load rating, size (height, width, revs per mile, etc...)

to see if they are comparable....
This is one of the things that you should have in hand before you go

and maybe they sold you what they had !

good luck

and FYI, spent 3 months in your area - beautiful area but I put on 10 lbs eating at that place right on the river - The Depot Grill - always wondered if it got damaged/closed from that train derailment - think it happened right in front of it ????

Thanks JohnBoyToo! You made it easy for me to understand. This stuff has always been abstract to me. Looks like I am good to go with either tire. I was unprepared because I had a brake caliper seize up and had to be towed to the shop. I was about a month out to replace tires so I asked for new tires while I was in the shop.

245/75R17 tires should be about the same diameter as 265/70R17. A general rule of thumb is if you go down (or up) one size on the width (246 vs. 265), then you should go up (or down) one step on the aspect ratio (75 vs. 70).

That being said, if you're using this truck for towing or hauling, my biggest concern would be the load range of the tires and the resulting load capacity of each tire? These should be molded into the sidewall.
