@ ibizzy Thanks for all your input.
@ RoHoe09 I like that look, despite it looking "small" like you guys are saying. You are the reason I started looking at Enkeis in the first place.
My heart says 22's but my mind says 20's. I was set on TBSSs for a long time, but....
I drive about 30,000 miles + a year, and with the gas doing what its doing........... and also thinking about wear in suspension in a commercial vehicle.
I am pulling about 18-20 MPG right now. At 65 MPH my tach shows right at 1500. I was in a loaner with LTZ 20's and at 60 MPH it shows 1500. So a difference of 5 MPH. Both trucks Suburbans with 2WD setup. Picture to prove it.

I figure it is a little worse with 22s ???
I understand the whole thing about overall diameter is what affects MPG and speedo and all, but I am also thinking about the rotational mass concept.
Tahoe/Suburban 17s like the ones Jacob (forget his screen name) used to have and I currently have weigh on mine exactly 63 lbs. on my scale.
The Enkeis on tire rack show 34.7 lbs. plus I figure 42 lbs. for the tire so total about 77 pounds.
77-64= 14 pounds per wheel. According to some other blogs about the topic; you figure rotational mass at
1.6 pounds vs. static weight. so....
14x1.6= 22.4 per wheels/tire
times x 4 = 89.6 pounds of weight added just by swapping wheels and tires. Gets worse for 22s 24s etc. hence why I am shying away from them.
