Stepping Down from 21" to 20" Atomic Wheels - Any experience with efficiency?

[mikehmb]

My AW09 Atomic and General grabbers is the lightest combo by far. I got about 2 or 3% improvement compared to the OEM 21". I don't think the weight has that much of a factor in it. Low rolling resistant tires probably would be number 1 on my list of factoring the efficiency.

You running the HTS60 or something else? That's great efficiency.

Yes. Hts60. The one with load index 116. Only bad thing is it doesn't last long either like the pirelli. Looks like I need to replace it before 20k miles. Cheap tire though. Low 200

I recently preordered the Atomic AWS in 20" which should be delivered in January. Stock tires are 21" so dropping down an size and plan to use the Michelin LTX MS2 tires on the new wheels. Anyone using these now and can comment on efficiency (R1S quad)? Curious to know how they compare to the stock 21" Pirellis and the lifetime efficiency of 2.73 kwh which I currently have.

What is your average speed?

34 is the average speed.
