Stock 2wd SL Tire Size Upgrade

I've seen plenty of posts here regarding tire size, but most regarding trucks with levels or lifts, or Pro-4x which sits a little higher than the SL and other models. Not many posts regarding stock vehicles with larger tires.

So, I've decided to go with Cooper Discoverer AT3 XLT in 275/60-20. Getting them installed next week and will report back with info and pictures. I've always used Cooper tires, and I'd rather not have to trim/remove mud flaps to avoid rubbing but we will see. Thought it may be informative for others looking to size up in tires without any other modifications.

Just a note, I'm not opposed to leveling because the front end does sit so low, but want to see how this works first. If I do decide to level, is that something that I should install personally or have a professional do it? I've done some similar work before, but suspension work of any kind is new to me. Also, will leveling negatively effect hauling? I pull a small trailer for work and a travel trailer fairly regularly and it sits level when loaded now.

Any and all input is appreciated!

I think the Cooper Discoverer AT3 XLT is not available in 275/60R20 but is available in a LT265/60R20 load range E 3,195lbs per tire (stock tire size). The Cooper Discoverer AT3 4S is available in a 275/60R20 but this tire is only a 115 load rated tire or 2,721lbs per tire.

Using a 115 load rated tire would be an issue with towing.

Interesting on the Cooper website for that tire it does not show that size, they show a LT265/60R20, LT275/65R20 and LT285/60R20, http://us.coopertire.com/tires/discoverer-at3-xlt.aspx

Good choice. I just put the same (though stock size) tires on my truck when my OEM Generals got a bit too squirrely in the rain. I love them so far. Good grip, and noise is significantly less than they look like they would be. Totally changed the way the truck looks.

I'm not a big fan of leveling on trucks. Seems to be fine for people that just haul air around all the time. Once you hook up a trailer, or load up the bed, it looks like the truck is squatting. For additional clearance in the front, I just removed the front air dam. Didn't notice any change in mpg, and has plenty of clearance for me. A leveling kit probably won't negatively affect handling other than looking squattier and making your headlights aim a bit higher.
