2023 Ultimate Denali tire options

yeah hate to say it but I am sure.  And so far the 275/50-22 Michelins are not doing much better.   Very disappointed at this point.  I'm temped to swap these out for the Bridgestones like I had before.

Update:   Sorry to say, after 5 months I am changing out the 305/45/22 Michelin defender ltx m/s tires.  After lots of data collection I determined they dropped my mpg by 4-5 mpg at 70 mph steady cruise.  
 

I went back to the stock size 275/50/22 Michelin defender ltx m/s 2.  The p275 version and not the LT275 version. 
 

discount tire recommended the P ( passenger car) version for the 1500 and the LT (light truck) for 2500 and above 

 

I will do more data collection on these tires and report back I a couple weeks 

 

One other thing I have to keep in mind is my original Bridgestone tires had a less aggressive tread  (AS vs. M/S) and were about half worn down.  Both of the factors reduce rolling resistance.   Installing new tires identical to worn out tires will have higher rolling resistance and reduced mpg.    So I don't expect my new tires to have as good of fuel economy as the one's I replaced.

I'm glad I read through this because I was going to ask about MPG degradation.  I anticipated much greater rolling resistance with that size but 4-5 MPG is enormous.  Thanks for posting.

At this point I don't think it was due to the size difference.  after switching to the stock size in the same michelin tire, I am not seeing any notiable improvement.  I'm going to go back to the Bridgestone Alenza AS 02 and see what difference that makes
