Correct Tire Size
Posted: March 1st, 2020, 12:06 pm
I have a 2003 Chinook Baja and currently running Cooper Discover S/T LT235/85R16 tires. I am concerned these may be too large for the dual wheels. Thoughts?

I believe that is a pretty common size on a 4wd unit. I run that size and have had no issues.

I have the LT235/85R16 Wrangler Duratracs on my 2000 concourse 4x4, They seem fit fine.

Mark,
The rig with the Alcoa's looks great. I have a question for you: Do you know if those are the "original correct size" Alcoa's or the newer ones with the slightly greater offset?
Reason I ask is that they quit making the "original" size ones in around 2016 and I can't find any. The newer ones have slightly more offset. If I'm thinking about this correctly, that would put the rear outer wheels about 1/4" outward and the front wheels about 1/4" inward. (Stock steel rear wheels already do stick out ever so slightly past the rear fiberglass body so I'd rather not gain any projection but.... I can't buy wheels that don't exist.)
If you have the newer/current ones and they fit okay, I'd be more confident in ordering them. (I have 2WD and stock height and so far have run stock tire size.)
The original size Alcoa had a 5.15" offset. The currently available one has a 5.40" offset.
I know that's not much difference but I don't want to experiment with $1500 in wheels plus I will need to have them drilled out for the extended metal valve stems before I even try them.
Thanks,
BG
PS: Just for the record, the original size Alcoas were part numbers 160241 (front) and 160242 (rear). The currently made ones are part numbers 160281 (front) and 160282 (rear).

Thank you for providing the Alcoa part numbers. I am interested in the alum wheel too, but I am not sure if I can transfer the valve stems and TPMS over to aluminum wheel. I will like to hear if any body have that setup.

After posting this question to Mark, I decided it might (also) be good to start a dedicated thread to this concept, so I did that. It's here:
