I've never heard of anyone having issues with aftermarket wheels while towing. If you're worried about it, pay close attention to the weight rating for the wheels you're looking at. I've towed 14-16K several times, 1,000+ miles each time and never had any issue with my 20's.

You can have problem using aftermarket wheels, but usually it's not the wheel's fault. 3 things are normally the factor here.
1. The wheels are mass produced to fit different vehicles. So what you have is a bolt pattern that fits, but the center part of the wheel does not fit snug on the hub. So now, instead of your lug nuts simply holding the wheel to the hub and letting the wheel and hub carry the load, the lugs and studs are now carrying the load of the truck.

b. which leads to the second thing. The aftermarket chrome lugs are not of high quality as a stock lug and with the added pressure of the incorrect wheel, the lug can fail. Most commonly, the constant in and out pressure the lug and stud will distort the threads and cause them to lock up on each other. Hints, you have a flat, and you strip off a few lugs trying to remove them.

third and this is mostly for 20s or bigger, or when the dealer adds aftermarket wheel/tires and cuts corners: Most people that get 20s or 22s end up getting tires that are not load rated. They will buy a 'combo package' or they don't have enough money to buy the correct tires and will skimp on the tires. I've seen this 100x over. Nice 20s on a truck with P series tires, like the Nitto Craplers or Toyo's. The reason being is most don't make a large load range on a short profile tire. So you go with what you can get to make it 'look' right, then load the truck down and boom.

Add all three of these together and it can be a recipe for disaster under a heavy load. Most don't ever have a problem, but most also don't tow to maximum capacity either.

After dealing with 20s on my truck for about 60000 miles, I've decided to go with H2 wheels now. They fit on the hub correctly like the stock PYO's, they use stock lugs, they are lighter than most aftermarket wheels, the stock Chevrolet/GMC center caps work fine and the off-set will allow the stock H2 305s under the truck too. I choose to run the 285s to keep it lighter and have the look I wanted. Plus, I also spiced it up by painting the wheels black but leaving some pollished areas for color.

Hope this helps a bit. Don't be afraid of aftermarket wheels, for the most part they are great. Just be awair of some things that can happen.

Here's a few pics of the H2s on my truck.
