20" or 22" wheels? couldn't decide so I got some lightweight 21"

    I was torn between the look of the 22" and the performance of the 21". So I spent a lot of time researching and settled on a compromise. I got 21" MRR flow forged black Fs01 wheels with Pirelli Scorpion Verde tires. The Scorpions have a long treadlife and Consumer Reports rated them as one of the lowest rolling resistance tires (hence the Verde name.) So these LRR tires combined with wheels that only weigh 26lbs (15 lbs lighter than the tesla 22"), I think I am happy with the compromise. The wheels are rated for the Model X weight wise and have a retail of abound $600 each. the only downside was they used more weight than I would've liked, and my mechanic didn't have black weights. So I'll be switching those out shortly. Sorry for the crappy photos. It is raining tonight so I'll take some better pics in the sun tomorrow. I didn't really notice any difference in driving feel, nor did I notice any difference in noise even though these tires do not have foam. The do have a fairly soft sidewall and were really one of the only choices in this in between size. 275/40 on rear. 265/40 on front. It totally changes the appearance of the car without (hopefully) as much of a performance hit. These wheels are actually lighter than the stock 20" by a few pounds. Tony c IMG_8941.JPG

    nice! Let us know your average wh/mi after you get some mileage on these. I wonder how much if any hit you'll see with the 21's.

    sorry for the crappy picture! It was in my garage and raining outside, I just got the X a few days ago and the wheels went on yesterday. I'll get some good pics shortly.

    Subscribed for photos. Always thought splitting the difference in wheel sizes would be a good compromise on performance and looks (21" for X, 20" for S).

    Does the Circumference difference of the wheel size screw up the mileage calculation in the car?

    The overall circumstance/diameter is the same. The wheel size increased by 1" but the tire height decreased by 1/2" on each side, so that made up the difference. it is called +1. stock tire is 45% of 275mm night on rear. my 21s are 40% of 275mm. = 275/40 r21 tire size,

    Said another way, the tire circumference does not change (appreciably), hence the speedometer is still just as accurate.

    And the front on 265/40 r21 would be the same as stock circumstance?
