So, I am reading up in various threads on here and across the internet. I don't really have a question, but some thoughts...?

I have a 2006 Pacifica with 3.5L. My wife stole my new Sentra. I am averaging about 24-25 mpg straight and level at 60 mph. I drive mixed highway and city. Accelerating in this thing KILLS mileage. According to SGII, it is 6-10 mpg until I stop accelerating. I go by TPS position to keep my accelerating in check. At idle it reads 12 and I keep it under 25 unless traffic is heavy, in which case I will not let it go above 30. Full pedal is somewhere around 78?

Anyway, getting closer to the reason I started this thread. I have 63,500 miles and the original tires. They are 235/65/R17 Michelin Energy MXV4 Plus's. They are LRR's (low rolling resistance), but the max sidewall pressure is only 44 psi, which I am currently at. They weighed 32 pounds a piece when new. They are 880$ a set.

I need new one's soon. I could make these last another 5000ish miles or longer, but winter is fast approaching and I need this vehicle to get me to work.

So, reason for thread. I could get new LRR (Low rolling resistance) tires. There are several choices. ContiProContact's are 44 psi max with a weight of 27 pounds for 436$. GoodyearAssurance Fuel Max's are 51 psi, 27 lbs, and 452$. Grabber HTS's are highly rated at Tirerack.com and 51 psi, 33 lbs and 480$. Shipping is another 45$.

I could get a set of non-LRR's that cost 400-800$+ and weigh between 27 and 33 lbs with pressures of either 44 psi or 51 psi.

Or, I could just get a decent used set of 4, in whatever various brand, in my size for 100-200$.

I am also thinking about different tire sizes. Maybe a narrower but taller tire for the highway mileage? Or for acceleration, a narrower and shorter tire?

Without any testing, all I have are ideas. Tires aren't exactly something I can just try out and return if I don't like them. I could get worse mileage with a new tire and really be, for a lack of a better word, sucking.

Whats best? A lighter tire with higher sidewall pressure?

So, does anybody have anything to add? Criticize, insult, confuse at will. I am looking for the best mileage for the least amount of money.
