Hey guys, I know there are about a million different topics about tires but I haven't found an exact answer after days of research.
I just picked up a 16 Sierra 1500 Z71 5.3L (Pictured below). This is my daily driver and MPGs are semi important, but I also didn't buy a truck because of its great fuel economy. I come from an old Grand Cherokee with a 5.7 Hemi.
I am planning on adding a 2-inch leveling kit, mainly for looks, and to have more clearance in the front. From what I've researched, by two best tire options with the stock wheels are 275/60r20 and 275/65r20. 33s and 34s respectively. Most people report no rubbing with either setup.
Honestly I just love the look of the 34s way more and they are not that much more price-wise, but they are all E-rated LT and all weight about 15-20lbs more than their 33 counterpart. The most towing I see myself doing is a 6x12 Uhaul and a small 18ft. boat, but I do take my trucks offroading/overlanding and in the snow quite a bit. I also do a lot of highway driving.
In reality, I would only gain 0.5" of extra clearance with the 34s, and I am concerned about how much the extra weight will affect my truck's performance, especially with the 5.3. Is there any reason why I should pick the E-rated LT 34s over the lightweight 33s, other than the fact that they look awesome? Could a tuner make up some of the MPG loss? Some report a better ride from E-rated tires, and treads are deeper as well.
Thanks!!
