Anyone else find some of the RPOs GM specs together strange

So I was a little disappointed when ordering my Silverado with the 6.2 and Max Trailer that it automatically configured the wheel and tire choice. (Chrome 20" with the all season tire) I would have preferred an all terrain tire and possibly a smaller wheel, especially after reading some of the reviews on the Eagle LS2. My buddy who works for Discount Tire also said they wear out pretty fast.

I initially assumed it was to make sure the load rating on the tires was up to the task but after a little digging the OE tire is nothing special load wise. It also has the same load rating as the same size A/T tire they allow on a 5.3 with the Max Trailer. Seems weird especially when you can get the All Terrain tire on a 2wd

The only thing I can think of that may come into play is the active noise cancelation. Maybe GM specs the A/S tire to keep the noise down where the noise cancelation can keep up.

Reading all the footnotes on the RPO codes is a dizzying task to cypher out what can be had with what. Some of which seems to make no sense at all. More than likely the bean counters had some input on it to limit the number of ways the vehicle can be configured.

I am on the fence about going with an aftermarket set of tires. If I did my buddy will hook me up taking the take offs in on trade. Most likely I would go with a heavier load rated tire with a more aggressive tread. If I did that I wonder what penalty I would pay in ride, noise and MPG. Any thoughts?

I've also heard folks bashing the stock Goodyears but I've had good luck with them. Got 63K out of the stock set on my '09 Silverado and never rotated them. I replaced in kind. It's the only tire I've had on these trucks so I can't give a true comparison but the ride quality and quietness are good. They can get a little loose in the rain if you push them.

I heard horrid things about the LS2. I have Eagle GT's. Go with at least an XL raring. Mine are rated at 2833 lbs per tire. My requirement was to comfortably have 4000 on the rear axle with a little room. My tores on the rear can handle 5666 lbs in the rear combined. Going to an LT will net you more, but 5666 lbs on the rear is more than the truck can take

So I guess I should be lucky that I got the Continental Cross Contacts on my 20" wheels instead of the Good Years?

I'm a huge fan of Toyo A/T II's, very smooth and quiet while giving great performance off road and in the snow. They have incredible tread life too, along with a 30 day money back guarantee. My first set on my Tundra lasted 55K miles and performed like new; I replaced them with the same tires. My 14 Sierra also has the Toyos, and after 9,000 miles they are performing great, except the ride is even better than on my Tundra because the Sierra rides better than the Tundra. Discount Tire will give you decent money on your OEM tires, though it sounds like you already have a buyer for yours. Good luck.
