New Tires Questions....

[MarkB]

So, finally couldn't take the noise of the OEMs (AT) tires and swapped them out for a new pair of shoes on the R1T and now have a couple of questions...

1. The new tires have a much higher PSI than the OEMs, is it recommended to set to the Rivian suggested PSI (found on driver side door) or to the new tire recommendation?
2. When setting new tire in the system it seems there are only 2 actual specific tires to choose from the OEMs and Goodyear Wranglers neither of which are what I put on the truck. So I just set it to "All-Season Tires (aftermarket)"..... is that it or should there be more options in the drop down?

Thanks in advance for any replies....

The tire change system only supports OEM tires and sizes - anything else is aftermarket.

As far as tire pressure; do a chalk line test and determine the ideal pressure for your aftermarket tires on your Rivian.

I ended up running my 35” Yokohama Geolandars at 52psi (80 max).

Depends on your new tire. If LT each tire manufacturer usually have inflation table with recommendations, based on weight at a single tire. IIRC, GVWR/4+30% margin and whatever psi corresponds to it. If not LT, chalk test to determine ideal pressure. 48 is what Rivian recommends for factory tires. And it’s what the TPMS is programmed to expect as normal.

As for tire swap in software, pick closest factory match or aftermarket. Either way your results are guesstimated, since you are using a tire that has not been tested by Rivian.

I'm close to replacing mine as well. Still have 50% of tread left, but they're god awfully loud.

What did you chose to replace them?

I made it past 30k miles on my Pirelli's and read tons of reviews on replacements, but ended up going with the Michelin Defender LTX Plat's..... they're not "ATs", but still have an aggressive look so hopefully they don't get loud over time like ATs, but still look great (at least to me) on the truck.

I ended up keeping my best Scorpion tire and throwing it on a rim I nabbed from EV Sportline so I also now have a spare!!!

How does your acceleration and handling feel with the platinum’s install installed? Have you had a chance to drive in the wet at all yet?

When my scorpions go I’m looking to go with those as well. The main downside I’ve heard is wet traction on those.

If those Platinums are 275/65R20, efficiency will drop. Those suckers are heavy.

Got it. I love the look of the AT's, and I've been offroad once now, but primarily use it for commuting and towing. The hiccup for me is that I'm in the southtowns of Buffalo. We had 155in of snow last season, and the boy and I are getting into snowboarding; so I want to keep the 3PMS rating.

I've been looking into the Michelins, but it looks like they discontinued them. Not sure which way I'll go now.

I've considered getting another set of wheels and running a 22in "sport" setup in the summer, and then keeping the stock Pirelli AT's for the winter. Could likely survive the full lease on those two sets alone.

Mine came with a spare, so I'm good on that front.

Why not the new gen2 OEM standard: Goodyear Territory AT RIV? Decent efficiency, AT appearance, 3PMSF and under $300 each. It's only slightly smaller than the 34.1" Pirelli AT. It's already in software as a known option, so better accuracy with instrument readings and predictions.

I've got those Platinums, and yeah, they're really heavy, but efficiency is still gotten a little better over the AT OEM tires.

What PSI are you running them at?

Didn't know that was a thing until right this second. I'll start researching.

I'm typically a Continental fan. Ran DWS06's on about 6 different cars now, and have run various other models on my wifes car for years. Even have Continentals on my bicycle . Unfortunately, the TerrainContact A/T's don't have the 3PMS rating that I think I want to keep.

Honestly, I'm on the fence about the 3PMS rating. I had continental DWS06's on my Q7 that weren't rated like that, and they did fine in most winter conditions I experienced. I also went off-roading with the NERC group in April, and there were guys on 22in sport tires going everywhere my AT's went, so I think that speaks loudly to Rivians traction control capabilities. I might not even need the 3PMS rating and just think I do. Need to do some more digging to make a decision.

Member @B Digs had a hand in designing the tire. It checks all boxes for appearance, efficiency, on-pavement manners and some off-pavement capability. While not the ultimate in any of those categories, it checks all boxes at a relatively low cost. The RIV version was developed specifically for the R1, with collaboration with Rivian.

The 3PMSF rating just mean you'll more likely to keep going when non-snow rated alternates can't continue further. Since you mentioned snowboarding, seem like having the rating wouldn't hurt.

As for 22" AS tires going everywhere you went with your ATs... that has more to do with terrain of the trail. There are places you would have been able to continue while they struggle for traction. Otherwise, off-road oriented tires wouldn't be a thing ever.

Unless durability of LT and heavier, more substantial, tires are required... I personally prefer lighter options. Or options that are not as heavy (from stock, which are said to be around 45~48 lbs). In steady cruising, tire weight is less of a factor on efficiency. However, real world driving isn't limited to steady cruising. Wheels/tires are rotating masses and act like gyroscopes. The heavier they are the greater impact on efficiency, suspension oscillation and steering response.
