Change them out for 265/60/18 Silent Armors and watch the milage go over 20 easily. The ratio of that size tire with the gears just seems to work much easier on the wallet and as I recently found out with mine, when you find the sweet spot for PSI on them (40 PSI all around for me) they roll so effortlessly on the highway, not to mention quiet and super comfortable. I recently took a new loaner LR3 for almost a week while mine was in the shop waiting for a Throtle body to arrive over the weekend and my wife turned to me and said that just then she realized just how much smoother my truck''s ride was compared to a brand new LR3. The right tire makes all the difference! _____________________________ 2006 LR3 HSE / 2004 Discovery II SE / NCLR Member (in reply to firchk) Post #: 13

RE: Gas Mileage - 6/21/2008 5:43:22 PM    davidlt Posts: 66 Joined: 1/21/2008 Status: offline I have the same tires and would love to get that milage (currently avg. 14 with the 91 octane). I know its early, but have you notice any potential for uneven tread wear with that little extra psi? (in reply to Jantiz) Post #: 14

RE: Gas Mileage - 6/22/2008 8:43:14 AM    Jantiz Posts: 425 Joined: 2/2/2007 Status: offline I made the change to 40psi very recently so if it was going to show signs of uneven wear, it would take a while longer. However, I am looking and will inform inmediately if it does. The front tires looked a little under-inflated at 36 where I had them before. Now they look just right at 40 so I don''t forsee overinflation wear signs, but will post quickly if I do! I''m fairly sure I lost just a hair of ride comfort with the extra 4 psi (either that or I have a very live imagination) but the extra gas milage I gained is noticeable as well and using less gas wins the battle right now! _____________________________ 2006 LR3 HSE / 2004 Discovery II SE / NCLR Member (in reply to davidlt) Post #: 15

RE: Gas Mileage - 6/26/2008 4:35:25 AM    davidlt Posts: 66 Joined: 1/21/2008 Status: offline Yeah, I figured it was too soon to tell. But I''ll keep an eye out for anything in the future. I''m going to increase the psi and see if I can get improved results. If I encounter any issues I''ll post as well. Thanks for the info. (in reply to Jantiz) Post #: 17

RE: Gas Mileage - 7/6/2008 10:20:16 AM    HULK2006   Posts: 17 Joined: 6/10/2008 Status: offline I made a 320 mile trip yesterday, on 90% highway and I averaged 21.2 miles per gallon. But I don''t know how accurate is the computer. But not bad at all with such a large car, with 300hp.I was driving at 75 MPH AVERAGE, with mid to low winds. when I turned the a/c off I was making 21.5 miles per gallon. Is this average or should i expect more? (in reply to axg1040) Post #: 20
