Default 20s worth it?

I plan on eventually doing a 2/4 drop. Currently I am on the 16 stockers but I may have some 20 Tx editions lined up. My dad said he hated having anything above 17 on his truck saying that the ride quality was kind of so so. What do you suggest, keep the 16 go to 17 and have a bigger tire or go with the 20s and have a skinny tire. Would the ride quality be good. This is a bit all over the place so if you need to ask me a question please do I apologize.

To me the 20s look the best with a 2-4 drop. So if your going for looks that the route I would go. They ride rougher but wasnt terrible.

I doubt youll notice much of a difference in ride quality. Go with the 20s. Hell I had 24s on a Sierra and barely noticed a difference. You definitely wont regret it.

I upgraded to factory take-off 2017 Silverado 18s on a GMT900 and love it. The rims were slightly wider than the 17s it came with. Even with the tires being the same width (just a slightly different aspect ratio to keep the tire diameter the same) as was on the 17s, it really tightened up response . I think the rim width really helped as much if not more than the aspect ratio change. It no longer felt "wallowy" over speed bumps, and better on turn-in. Maybe you could find some 18s you like as a compromise.

If you don't care about the extra rotating mass, go for it.

ride quality also depends on how much side wall you go with on the tire. I personally think the 20's look best with a drop

I ran 275/55/20's on a 2/4 drop Sierra long bed truck. Would only rub on full lock. I would have downsized my tires slightly if I kept the truck long enough.

I've had 17's and 20's on other trucks. I currently have 18's on one and 20's on another. They honestly are not an issue at all. The 18's ride a bit better than the 20's but it's just not a problem imo.

for a truck, i prefer to have the wheels just big enough to clear the brake calipers... but that's just me

taller sidewalls tend to have better ride feel than thin ones, and going from 16 to 20 (keeping the same tire height) will be noticeable, but i doubt it'd be any real detriment other than increasing the average radius of your wheels' rotating masses (which might increase acceleration & braking time/distance a little)

I have this tire size on some factory take-offs and the ride is pretty good.
