In the test it looks like the 21" areo covers were missing. At a steady state highway speed, that will make a difference.

I am surprised at the result. IMO the length of the test was not sufficient. I have done back-to-back tests before and gotten different results even with the same setup. You did a good job trying to match the tests as closely as possible but there are just too many variables such as wind speed, temperature of the road, etc.

Physics is physics, and aerodynamics are very important. There is a reason the most efficient wheels have areo covers. It is not for appearance.

Of course, rolling resistance is also very important. It is possible the rolling resistance of the tire offset the aerodynamic losses due to the rims. The best approach would be to put the same tires on each rim and do multiple tests for a much longer distance. And the areo covers should be on the OEM rims to be a fair test.
Not many people on the forums talk about rolling resistance. How is the average consumer like me to know what tire on the market has least rolling resistance? I wouldn't mind buying one for my next set to compare range. Excluding the stock pirelli's of course.

Apologies if these questions have been covered before, but does the extra width of the AW10 in the 20" size present any clearance issues? What is the diameter of the AW10 & tire combination when using a 60 series tire like a General GTS60 275/60? Will the wider wheel negatively impact range?The load rating of the AW10 is 2,580, which I think is less than the stock Rivian wheel. Does this load rating have any safety or performance implications?

FWIW, Rivian stated the aero covers on the new wheels add about 2 to 3 miles of range. So less than a 1 percent benefit.

Hard to believe, but they would know. I expect that is EPA range, not high speed highway range. At 80 mph they have to be much better than a 1% improvement.

Maybe. But... it's a rather large and reasonably aerodynamic brick with wheels that are mostly tucked in pretty well. It doesn't really surprise me personally given the marginal gains you get something that's as aero as a model 3.

In the EU they rate tires that indicates their rolling resistance. Here, we don't. You can find the EU rating on tires in their market, but you have to be sure you are really buying the tire that is rated.

IMO this is a big issue for people like us who think range is important.

Other than reviews on Tire Rack, and maybe a Tire Rack test comparison, there is almost no way to know. Tires that are designed for low rolling resistance will be marketed that way, so you can at least know they should be better than tires that are not designed to have low rolling resistance. But of course, some are better than others.

It is frustrating. I think the market will sort it out when enough buyers care about it. Right now, the percentage of the tire buying market who cares is small.

By the way, there is a corelation between rolling resistance and wet road performance. Lower rolling resistance means worse wet road performance. Always. So you can look at the wet performance reviews and pick tires that do poorly on wet roads. But that isn't really a great way either. Poor wet performance does not necessarily mean lower rolling resistance.

Oh well.

I agree. Aerodynamics is a funny thing. Something that looks aerodynamic might not be, and something that doesn't might. You can't tell necessarily by looking at it. Testing is what you really need to do. Of course if it looks more aerodynamic, it probably is. But it's not a guarantee.

Happy start to the week, everyone!

By popular demand, we've made changes to the [AW08] rims for Rivian. We removed all the fake beadlocks and made the valve protected as you requested.

They will soon be available for pre-order with a 20% discount. This design will be offered in Gloss Black, Satin Black, Satin Gunmetal, and Satin Bronze, so start thinking about which one you like best.

Dang, these are good looking wheels.
If I didn't already have a set of 20s from you, I'd be ordering these now :)

Damn, that Aw08 is fiya in that matte black !! Wished it was there when I ordered the Aw09. (still look good though)

Man o man…those look so much better. If I didn’t have a custom wheel I love even more in production with y’all (yes, I’m originally from Texas too!), I’d totally be on board with this wheel.
