I know all the considerations, but which is more important? For example I'm looking at:


Michelin MXV4 Plus, $300 used
225/55R17

LRR: Green XLow Rolling Resistance Tire Technology
Treadwear: 400
1521 lbs.
44 psi
10/32"
26.8in
26 lbs.
rev/mile 785

Or new $400 Hankook (bought at the same time as my rims will mean free install and balance so only $40 more than used Michelins)
225/55ZR17
Treadwear: 420
1819 lbs.
50 psi
10.5/32"
25 lbs.
26.8" in dia
rev/mile 775

So in this case the higher load non LRR tire is more PSI and lighter weight. So is it possible that the non LRR will give better fuel economy since I will run either at max PSI?

Thanks KSA8907, I didn't read your post when I replied because I hadn't refreshed.
