Easy. Early reservation quad: $78,000. New quad: $125,000? Worth $47,000 more? Nope.
Why can't you? You'll lose some articulation for off roading I'm sure, but they'll fit with proper offsets. They're not doing any shortened axle or widened rear arches on the new quad from what we've seen.
If you have the new rims that go with the g2 quad on a g1 quad it would be fine but if you’re just putting different tires on the existing g1 22” wheels I think the 305 will rub.
Exactly why I mentioned proper offsets
lots of people, especially the ones that would want 305s, buy aftermarket wheels where the sky's the limit. I went 22x9 with a slight offset change.
Madhat: is the huge offset just to clear the calipers?Exactly why I mentioned proper offsets
Well, a Carrera is around $130…a Turbo S is around $270. Is the extra $140K worth around 1 second 0-60? Of course not…unless you WANT IT! Then it is! Disposable income sets the “worth”
I wonder if the wides will have a 20 inch wheel available eventually. (20 inch wheel club represent!)
We're talking max performance tires, I don't think you'd really want to go outside of the recommended wheel widths. I'm somewhat tempted to get the 305s and see how they mount up on the OG 22" rims, but that's an expensive experiment.
100% this. There is no such thing as "worth" at the 100K dollar price point. Outside of a few specialty vehicles built for specific purposes like a garbage truck, there is no vehicle you NEED at 100K. It's all wants once you get get up that high in price, so worth is subjective. It depends on how much you have, and how much you're willing to spend.
Bad communication on my part. I meant to further my comment that people do aftermarket wheels... I'm still running 275/50/22 Toyo Proxies on the 22x9.
The answer is easy enough, and that is no comparison - the PSS5 would blow away the Toyos in this instance. Not only the PSS5 have more sticky rubber and the wider width, but the experiment would involve pitting the Gen 2 Quad against the Gen 1 Quad with much more hp/tq.
No comparison 305 on the rear with a Gen 2, but there are already guys out and about with the PSS5 in 275 on Gen 1s.
Not a perfect description. Several items listed for Gen2 are on the gen1 quad. So Chat GPT got some of it wrong.Lots of differences. Better to ask ChatGPT/CoPilot for the summary. I just did and it is quite good.
EDIT: Pasted below, hopefully it copies nice.
The differences between the first-generation Rivian quad-motor vehicles and the second-generation quad-motor models with over 1,000 horsepower are pretty dramatic—especially under the skin. Here's a breakdown of how Rivian evolved its flagship R1T and R1S platforms:
Powertrain & Performance
Feature Gen 1 Quad-Motor Gen 2 Quad-Motor (2025) Motors Bosch-supplied Rivian-designed, in-house Horsepower 835 hp 1,025 hp Torque 908 lb-ft 1,198 lb-ft 0–60 mph ~3.1 sec 2.5–2.6 sec (with Launch Mode) Quarter Mile ~11.8 sec 10.5 sec
- Gen 2 introduces Launch Mode, which optimizes suspension, battery, and traction control for maximum acceleration.
- Active torque vectoring and staggered tire setup (Michelin Pilot Sport S5) improve handling and grip.
Battery & Range
Feature Gen 1 Gen 2 Battery Pack Max Pack (~135 kWh usable) Max Pack (~149 kWh usable) Range ~314 miles ~355 miles (estimated) Charging Speed ~200 kW peak ~220 kW peak
- Gen 2 uses a redesigned battery pack with improved thermal management and simplified architecture.
Software & Architecture
- Gen 1 relied on Bosch ECUs and more than a mile of wiring.
- Gen 2 slashes complexity with in-house zonal architecture, reducing ECUs from 17 to 7 and removing 1.6 miles of wiring.
- Enhanced infotainment, driver-assist tech, and one-pedal driving with three regen levels.
Interior & Trim
Feature Gen 1 Gen 2 Trim Level Adventure Ascend (premium) Materials Vegan leather, basic audio Upgraded vegan leather, premium audio, electrochromic glass roof UI & Controls Touchscreen-heavy Improved UI, better climate controls, Dolby Atmos audio
🛞 Ride & Handling
- Gen 2 features recalibrated suspension, hydraulic roll control, and new dampers for smoother ride quality.
- Off-road modes like Rally and Drift offer tailored torque delivery and suspension articulation.
The Gen 2 Quad-Motor isn’t just a refresh—it’s a full-on reinvention. Rivian’s move to in-house motor design and software integration has unlocked supercar-level performance in an electric SUV or truck. If you’re into EVs that can both shred trails and smoke Lamborghinis at the drag strip, this one’s a beast.
