Nope, no rubbing issues or clearance from suspension parts at all, the tires that were originally on them didn't really stick out from the wheel wells at all, but were right at the edge of that, they were 245/45ZR20's. The new tires I had put on yesterday are Yokohama Geolandar H/T-S 275/45R20 so they stick out from the side of the rim lip a little (since the top of the tire is now 30mm wider - 275 vs. 245) but I like that look on the rim, and knowing that there won't be issues of the rim scraping curbs by accident, less roll over on the tires taking corners etc. plus, I think it looks kind of 'tougher' with the bigger wider tires lol.
The wheels are "Menzari" VM08 I believe, they are a 20x8.5 wheel, +38 offset, 5x114.3mm or 5x4.5" bolt pattern, the hub I believe is around 72.2 or 73mm, so hub centric rings are needed. I also had to use the 'tuner spline drive' lug nuts in the correct Kia size, I can't remember what size that is, but it's the same as the OEM lug nuts. Also have the locking nuts on the wheels as well, they are not the typical ones that Kia's usually come with, they are shallow, no cap on top, I think they are meant to go under a cap, are only about 3/4" tall or an inch at most. The front wheel spokes just barely clear the brake callipers, there is probably about 2-3mm of space between the caliber and the back side of the pokes, which originally worried me as I was mounting them on the hubs, but they clear and move freely, and I haven't had any issues yet with rubbing, scraping or the spokes coming into contact with the callipers at all, so that's good.
I had a look at the back of the OEM Kia wheels, and I think they are like +50 offset, so it would have been good to get wheels with a little more positive offset, but these were second hand, so that wasn't an option, plus, most manufacturers of aftermarket wheels only make up to a +38 or 40 offset at most, so you'll typically run into the issue of them 'sticking out' a little, especially when you go with a wider wheel like 8.5" or 9, 9.5" and 10" for sure, that 9.5 - 10" rim with the wrong sized tires would definitely be running into rubbing issues, especially on the back wheels with the control arm/suspension arm that runs between the axle going towards the front of the vehicle and the inner side of the wheel and tire. But I've seen at least one Sorento on here with 22" wheels, so if you get the correct back spacing/offset, and tire size, you could even go up to a 22" wheel if you wanted to. I stuck with 20" for mine, that's big enough for me, and I don't want a tire with a shorter sidewall than 40 or 45 series for the ride comfort etc.
In front, the top of the tire is about 1" from the bottom of the strut tower, so there's plenty of space in there, no rubbing etc, but if you went any bigger with the tire (275/50R20 or even something like a 245/60R20) and increased the over all diameter any larger than the 29.5" or so that these are, you'd definitely be at the max or beyond as to what will fit under that strut tower base.
As for the ride comfort of the 275/45R20 compared to the original 235/6018 it's pretty close, feels just as smooth, maybe a tiny bit rougher on bigger bumps etc, but not earth shatteringly worse, at least with the tread on these tires at about 70 - 80% it feels nice and smooth, to me anyways. You definitely would not want to run with a 30 series or 35 series tire on an suv like the Sorento, that's just going to give you a bumpy uncomfortable ride, better cornering maybe, but you'll probably dent the heck out of your wheels before you get the chance to go racing around the turns.
All in all, I'm happy with these wheels and tires, looks good (for my taste) and rides nice still, so these will be my all spring/summer/fall wheels for sure. After that it's back to the factory Kia 18" wheels with winter tires on them, in the OEM size of 235/60R18".
