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
