First off, this is not a perfect test. "Ain't nobody got time for that".
So, my original tires were some mastercraft tires. They were a little bigger, but according to my gps, it was barely any different from the speed. I recently checked with some used potenzas and about the same.
After about 3 complete tanks with the mastercrafts, I got:
- 52 mpg (work route. some hwy and some stop and go)
- 56 mpg
- 60 mpg (mostly highway and had some good drafting)
- During this time, i have had had a lower bumper air block. (not the whole time).
- These calculations were by calculator. The FCD always reads a bit higher
Haven't started a full tank yet, but will very shortly. Just picked up the used potenzas today (got them in a junkyard
Aside from that, I have also added a few pieces of under body plastic that were missing. Another note - The Autostop does not work. Never has and haven't figured it out yet.
So, over the next months, I'll try to remember to note my tanks. Would really like to compare other LRR tires, but that won't happen. I'm not here to debate other LRR vs the Potenzas, nor am I here to debate the financial aspect of it.
