Trees are more friendly than concrete and metal … glass half full
Seems to be a combination of excessive regen that doesn't cooperate with traction and stability controls (and abs pertains to the brakes, but should cooperate with preventing regen from causing a wheel to stop rotating) and tires that get cold at freezing temps (not okay for even a 3PMSF tire.)Is the snow performance really that bad? Why? Is it the factory tires?
Some people may be aware of this, but for those that do not, LT tires have more plys in the sidewall, anywhere from 6 to 10. It increases the load rating but also makes the ride sometimes signficantly rougher. You might feel and hear every bump, and a washboard road might make your teeth rattle. Buyer beware. I found out the hard way on a Suburban that I owned years ago and got LTs for loaded towing.I chose the same tire, the LT3 on Amazon.

I've done the same and am thus far very happy with the Nokians, how about you?Found 20’s to be pretty weak on ice, slides way more than my KO2’s on my Ram. Installed Nokian LT3 after feeling like a newbie on the ice rink. Sorry about your hood, think we all cringe if anything happens to our trucks
Correct. An important point for everyone reading along to consider.Some people may be aware of this, but for those that do not, LT tires have more plys in the sidewall, anywhere from 6 to 10.

Exactly this! I'm actually shocked that the Rivian performs SO poorly in lower traction situations on DECEL. Acceleration is fantastic! But deceleration can be downright scary. Have experienced the tires locking up on slick road during a fresh drizzle. Obviously the regen should have known to reduce and that I wasn't instantly stopped, but it didn't. Instead it just slid to a stop from about 5 mph, wasn't full regen either, well not until the slide started and I intuitively let off the accelerator. In hindsight the only thing I could have done was step on the accelerator to stop faster...good luck training people's brains to do that!is the wheels locking on regen and likely not unlocking in like ABS would.
I switched from the 20s specifically because my truck was sliding laterally and not stopping in a *parking lot* and stopping from less than 5 mph in a situation I've never experienced.
Was wondering the same thing — with regen as strong as it is typically, would feathering the accelerator be equivalent to braking, contributing to loss of traction? Wonder if this means the upcoming Snow Mode would reduce regen by default?If the issue it won't let the wheels free spin so you slide? Otherwise forwards (while accelerating) traction is fine?
If they had a two-pedal driving mode, snow performance would be fine?
Yes! I find putting it in neutral and modulating the brakes is the only way to control the R1T on a super-slippery surface. The regen is just too strong, locks the wheels so you can't steer and the whole vehicle slides depending on the camber of the road. I wish there was a way to just turn regen off. I'll wait and see what 'snow mode' brings. (20" A/Ts)Feels like the traction logic programming. Next time I'll kick it into neutral down the hill.
Last night was super-slippery here in Bend. I spent some time experimenting, driving around slowly on hilly side streets. Coming to a stop using regen was uncontrollable. The wheels locked up so the vehicle couldn't be steered and the whole vehicle would slide depending on the camber of the road. Adding some power to defeat the regen helped bring the vehicle back under control but I found putting it in neutral and modulating the brakes was much better. I wish there was a way to turn regen off. We'll see what 'snow mode' brings. (20" A/Ts)It's not the brakes. the ATs are not good at stopping or turning when they are cold in packed snow or slippery surfaces.
This. I'm going to continue to sit on my soap box on this. The 20s are not good at stopping and turning, at least with a vehicle with the weight of the R1T at the tire pressures Rivian recommends.
