Just purchased these Firestone Destination A/T2. Love these tires. Ride is amazing and super quiet.  Tread compound Firestone used is the key.  Couldn't be happier.

Michelin makes the Defender LTX M/S in 275/50r22 and 305/45r22. The Michelin outperforms that Continental in every category. 

I think you missed what the OP wants and is asking.  The Defender LTX 275/50/22 doesn't come in an all terrain and the 285/50/22 comes in an LT tire. It's comes with an aggressive tread in Nitto, Toyo and Yokohama and are expensive.  Not the best ride and not quiet. The OP doesn't want an aggressive noisy tire and wants a quiet smooth riding all terrain tire to replace the 275/50/22.  285/45/22 is the best option.  I went with the  Firestone 285/45/22 all terrain on my 2022 refresh and couldn't be happier.

 The Michelin Defender LTX MS.

 

The Continental Terrain Contact AT tire the OP is interested in is not really an AT tire, it's more of a highway tire (like the Michelin Defender) being marketed as an AT tire. The Continental is not 3 peak rated. The Michelin will outperform that Continental all day on all terrains. 

 

On another note, going down to the 45 sidewall will reduce comfort and wheel protection. It also looks too thin on these Silverados. I wouldn't go any less than the 50 sidewall at 32.8". 33-33.5" would be better.

I've had 285/45/22's on past trucks and my '19 RST had Michelin Premier LTX 275/50/22's.  I must say, these Firestone A/T2's on my 2022 refresh ride better than the 275/50/22 Michelins did.  I'm more than happy with the ride quality and road noise.  Firestone is using a new updated tread compound on these AT tires called hydro grip which has more silica in it and something other AT tires don't have.

The Michelin Premier tires are not even comparable to the Defender LTX. I don't know much about the new Firestones you have, but I know they don't make them in 275/50R22, so I wouldn't be interested in the first place. These trucks really need more sidewall & diameter, not less, in my opinion. The 285/50R22's while more expensive, really hit the sweet spot for these trucks at 33.5-33.8" overall diameter. The LT ratings on the 285/50's also are a benefit for our heavy high torque 1500 Silverados.

I’m currently in the same boat. I have a 21 Sierra Denali w/ 22’s and am looking to replace the Alenzas w/ an all terrain tire. Are 285/45/22’s basically the only option beside going to E rated 285/50/22’s?

You can use a 305/45R22 too. But the 285/50R22 is the best option for AT tires on these trucks. You won't notice the E rating at all if you are going to real AT's anyway.

@diamond817 Thanks for the reply. I actually ran 285/55/22 G2's on my 17 Denali and the ride suffered dramatically due to the added weight. I'd really like to stay with an XL tire if at all possible. 


Does anyone know if the 305/45/22 will fit?

The ride suffered dramatically due to added weight or because of the tread pattern of the AT tires? I think it's more because of the tread pattern. Ride is going to suffer when you go to real AT tires, no matter what the load rating is.

Scroll down to bottom of first page to see 305/45R22's on a stock GMC Sierra:

The ride suffered from pulling the added weight of the extreme heavy E rated tires. The 10 ply E rated tires are also a lot stiffer than a XL tire, hence the tougher ride.

 

I’d really prefer to go with an XL tire which is why I’m asking if the 305/45/22 would possibly fit.  I’m looking at AT3’s and G2’s so the deeper tread has me concerned they may rub. Thanks

    • Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-
    • Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.     
    • I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
    • I do too. I’ll never be stuck again 😂
    • It has happened to me a few times. I carry a jumpstart-tire inflator with me.
