How do different tire load ratings and towing capacity of the truck relate to each other?

 

I'm wanting to change to a different tire make and size that is different from what came from the factory.

Maybe a Michelin LTX M/S or LTX AT 265/75/R16 or 265/70/R16.

 

We will be getting an RV soon so towing will be a factor.

 

Thanks!!

You truck comes with 10 ply tires from the factory.This rating coinsides with the GVW of your truck.This is required by the DOT ,I mean that your truck comes with those 10 ply tires because the tires must be rated for the max weight that the truck can handle.I would not put less than a 8 ply rated (load range D) tire on your truck especially if you are planning to haul an RV or anykind of load.I could not wait to get those #### firestones off myself.I also want to tell you that the higher tire you go with the more sway you will have under loaded conditions.Keep this in mind.............Gun :angry:

I put LT 265/75/16 Michelin LTX M/S (load range "E") tires on my HD.  They have the same load range as the stock Firestones, but their carrying capacity is about 400 lbs more per tire than the stock 245's.  I'm guessing that is because they are  one size larger.  Maybe a 265/75/16 in a load range "D" would be closer to the stock tire capacity.

 

I really like my Michelins and I tow a 32' trailer with about 1000 lbs of tounge weight.  I pulled it last weekend and the tires were great with approx 50 psi in them...

265/75 good. 265/70 bad!  :)

 

The 265/75 is 1 size larger, and provided you get the same (or greater) load capacity, you're good to go. However, a 265/70 is probably shorter then the 245 you have on there now. The 70 series aspect ratio has a shorter sidewall then the 75 series, so when you go wider you have to go taller in order to compensate. 265 is taller, but it might not be tall enough to equal everything out. Personally, I'd go for the 265/75 myself.

      I could be interested if they axed cylinder deactivation and at least have a button for stop start. I’m sure the HP numbers will be higher. I would want a longer warranty to help build confidence. I’m a less is more guy as I get older. A V-8 work truck model would be my choice. I know a few outfitters for custom additions I prefer.

      It's official. GMC pulled the covers off the next-gen 2027 Sierra 1500, and we got the first official look. Full breakdown here: https://www.gm-trucks.com/next-gen-2027-gmc-sierra-1500-v8-trim-changes/   The quick hits: SLE and SLT are dead. The new core retail trim is just called "Elevation". Two new V8s, a 5.7L and a 6.6L built with high-performance Corvette architecture roots. No horsepower or torque numbers yet. The 2.7 TurboMax finally ditches the old gearbox and gets the 10-speed automatic. AT4X moves to larger standard 35-inch tires with front and rear e-lockers, Multimatic DSSV dampers, and heavy-duty Jounce Control Dampers. Over 60 inches of combined display on Denali Ultimate and AT4X, complete with a motorized articulating center screen and an adaptive passenger screen. Seven simplified trims across the entire model line to clean up ordering confusion.   So let's get into it: New 5.7L and 6.6L gas V8s with custom active exhaust tuning and a Corvette connection. Is this the exact engine lineup half-ton traditionalists have been begging for? Purging the iconic SLE and SLT names after all these years to lean entirely on Elevation as the high-volume core. Bold move, or a mistake? That motorized articulating 16.3-inch screen that slides up to reveal a hidden dashboard vault. Awesome mechanical theater, or does it make you nervous about long-term durability? Physically lowering the headlamps in the front fascia to improve road courtesy and stop blinding oncoming traffic. Smart real-world engineering, or does it hurt the truck's aggressive stance? What trim are you putting your name down for on day one? Drop your first impressions below.

      My overnight hospital stay turned into five.  I developed a post operative fever and an erratic  heart rate.  A blood clot in the lungs was the culprit.  This is apparently a common post surgical complication and easily remedied.   I was the youngest in a four bed ward and a Doctor with a Geriatric specialization was in charge of my care.  All of the nurses were good and some were outstanding at dealing with old people.  It was very evident that my age triggered a different level of care!  My advice to any senior going for a hospital stay is to have a trusted family member advocate visible.  If not, you will still be well cared for, but you may discover that your voice  isn't as strong as it once was!
