Hello, new to the site

I'm doing a small upgrade to the wheels and tires and adding a couple of inches. Just needing help with a small part that I am not familiar with. I have a 2.5" Hellbent lvl kit on it's way. Decidied to run 275/60/20 Toyo A/T. I'm going with the American Racing Chrome Burn for the wheels. They are 20x8.5 6/5-6/135. There are no choices for offset and backspacing they come +30mm, 6.0". I currently just have the stock 18's. My question is will this pre defined offset and backspace work? I do not want to have to add flares to my truck. If this question has already been asked I appologize and I did attempt to search for my answer on here first. Any help would be greatly appreciated. I posted this in general discussion and recived no answers. I'm hoping for better results here.

 

Try posting this in the year section for your truck. I think you may get better results from your question that way. I can't help you, I don't know anything about offsets and such.

Good luck!

 

That is what I posted it under initially with no results. I'm not sure what else to do, but thanks for the help.
