Hello Group,

I just recently purchased a 2018 Challenger T/A 392. I'm looking for pics & advice on what some of you run for tire size, with out spacers or major modifications. I want to run a drag radial, in a 305/35/20 or 315/35/20. I understand some of the plastic trim, on the inner wheel area may need to be trimmed. Here is my question, I'm going to purchase a set of rims MRR M392 20x11 from American Muscle. I did not see an offset option (or I missed seeing it). Do I need to find out the offset, or will they fit with the proper backspacing as needed. If you happen to know the offset in mm is, I would greatly appreciate the info...Thank you in advance!

I have 20x11 rears with ET20 offset, 305-35/20 tires. They slightly stick out. In this video clip you can see how they fill up the wheel wells and the overall fit:

If those 20x11's are with an ET24 offset, with 315's you'll likely need to trim the plastic wheel well water shields. My wheels were an ET20 offset with 305's and they had to reshape the plastic with a hot air blow-dryer so that the tires would not rub against the shields.

I run the Voxx Demon replica 20 x 10.5 with 25 offset. I use a 3mm spacer to keep from rubbing. I have run 295 and 305s tires. without the spacer they barely rub the plastic insert. The offset of the 18 x 11 Demon rims is 22 for reference.
