I've had the 2363 RAM wheels on and off my T for 15k+ miles and its a great option for a cost effective wheel the run AT's and matched to the 21" or 22" OD. I may even do a second set with All-Season 20" tires for max range since the 21's are $$$ to replace.
Yes needed, Hub Centric rings, 4pcs from Wheel Connect through Amazon with great communication and fast service. SKU# HR7780-6410A These will allow the smaller Rivian (64.1mm) hub core to remain concentric with the larger RAM (77.8mm) wheel center bore.
Just for S%#T's and Giggles, I too got my T with 21's and I built a budget AT setup for off roading. Since the OE Pirelli's are SO expensive I have been considering building a second set of All-Seaons on 20" wheels and going with this tire. Glad to hear your feedback!
For those wondering on...
@dp351 are you running hubcentric rings as well? Nice to see more of us jumping on the DIY budget setups and I have considered these same wheels to replace my 21" roads for a street setup since I am running the other Dodge 2363 wheels as my AT setup. Looks great!!!
Not exactly spacer related, but I am running a more aggressive wheel/tire combo that put's the tire about 18mm further outward overall. It's all done in my wheel offset (+19mm) and to me the fit is more aggressive without loosing function or range.
@dp351 Grab yourself a hub centric ring if you didn't already so that your spare has the proper fit.
Amazon retailer Wheel Connect sells sets, SKU# HR7780-6410A These will allow the smaller Rivian (64.1mm) hub core to remain concentric with the larger RAM (77.8mm) wheel center bore.
Depending on the weather, I’m seeing very similar numbers to the trucks that are factory equipped with the Perelli scorpion tires. I was averaging around 2.3 mi./kW but now that winter has set in it has averaged down to 2.0 mi./kW This picture is my total average across 5600 miles with this set up.
I made my own pucks, but that's easy for me to say since I have a home fab shop, 2 lifts, welders, and machining equipment... I'll update with pics this weekend
