This is the tire I am getting.
155/80/13
Kumho Solus K21
Section Width: 6.2"in
Overall Diameter: 22.8"in
Weight: 14lbs
Tread Width: Not Listed
Revs per Mile: 914

These are the tires on my car right now.
I currently have 175/70/13 size "Radial X" on it right now came with the car.
Section Width: 7"
Weight: Not listed but im sure 16-17.5 lb range.
Overall Diameter: 22.68
Revs per Mile: 917

New tire
Section width will be .8" smaller
2-3 lbs lighter
and rotate 3 less times in a mile

I never tried comparing tires and RR because all of my previous choice in tires were not "ECO" minded. I just found the stickiest and highest Z-W rated tires with the tread wear around 150-280 and AA rated. I did have a set of Yokohama S.Drives 205/55/16 on the rx7 and they were great all seasons. very quiet and stiff sidewalls. To bad they do not make them in my size.

As you can see the Kumho Souls tires are lighter/skinnier/taller then what is on my car right now.Now I can see why people think the RR is worse on the OEM recommended stock tire but like "Thymeclock" said "I will judge them for myself" and see if the RR is really that much worse then the ones I have right now.
