Do Bridgestone Dueler H/L Alenza Tire have any negative impact on MPG by lxpatel

I just had replaced all four Factor Goodyear Integrity RSA changed to Bridgestone Alenza, original only lasted for 23k, New feels lot better, warrantied for 65K and seems to handle better but i noticed that factory only uses Goodyear RSA or Michelin MXV4 S8. Will New Tires bring down MPG? has any one else tried these tires?

after 2 tanks of gas, I'm avg 29.9 mpg (70% HWY with 60-70mph) I'm very happy with the gas mileage I'm guessing the RX350 would avg ~20-22 mpg at most 3.5L engine would get.

MPG Reality Check by carquery

I've been reading these posts for a while and it seems like the majority of 400h owners are getting good mileage out of their vehicles (when compared to a non-hybrid SUV of the same size/weight). The NY Times just reviewed the Lexus 600 sedan hybrid and made mention of how poorly they thought the 400h performed mileage-wise. Their major issue seemed to be that the hybrid system was being used to give the car more horse-power vs. better mileage results. When the Times reviewed the 400h, they really took Lexus to task for making it seem like they had produced a fuel-efficient SUV, but contended that it was barely any better than the non-hybrid RX series and certainly not worth the extra cost.
 
I'm wondering if all the 400h owners out there are happy with the mileage that they are getting at this point. I realize that is completely subjective and also that no one is getting the mileage promised on the sticker. But, compared to having bought a RX330, would you still have purchased your 400h? I'm close to buying one, having trouble getting the price down to where I want it ($45k-ish. Best offer so far is $47k) and wondering if it is worth the extra $$. I live near Hartford, CT for what it's worth.
 
Any input would be welcome.

2800 miles on our 400h. 90 miles round trip to work. 2/3rds highway miles, but that is relative. The highways are the beltway and I66 in Virginia. Often the dirt roads move faster. In any case, 27.6 MPG using regular gas. We are very happy! The 400h replaced a 05 Niddas Mirano that on the same routes averaged 21.8mpg. There you have it. We love the 400h and would do it again!

We have owned our 400h for almost 2 years now..I had to wait one year for it since when they were promised to come out, they did not. Since I was on a waiting list, there were NO discounts. Also, I wanted a specific color and the Mark Levson sound system. Of course, that cost more. I also bought the extended warrenty b/c this was a very new concept and who knows what can go wrong. Over all, we paid over $50,000 for it. I do not regret one single dime spent on this luxury and performance for this vehicle. It has been such a joy to drive. We average about 26.5MPG. We have it serviced every 5000 miles. The sevice center in Annapolis, MD is supurb. They always give us a loaner and we have driven many different models of Lexus. Hope this information helps..Anne

I paid $50,000 out the door 2 years ago in May. The 400h had just come out around March or April that year. Mine is the first level in black without the Mark Levinson or DVD player, but I have loved this car from the moment I drove it. It has the acceleration that I demand in driving. ( fast get away from drunk drivers and acceleration to get on Atlanta Hwy.) Also the gas mileage savings balances out the extra cost. I could have had a fully loaded 300, but it would not drive the same. Such a smooth drive. My husband does not get the same gas mileage, as you must adapt to the synergy drive. Hope this helps. At 44,000 miles I still average 27 mpg.

I drove past the Annapolis dealership last Labor Day while on vacation in the DC-MD-VA area! Of course then I was missing my RX 400h, as we were in a rental. I just had my 15K check, and I am still getting around 29 mpg on regular. I am fairly gentle with it - I don't "punch it" unless I have to really get around something/someone quickly. My dealer rep told me when I saw him last week, re: mpg "you've got to earn it." Meaning, keep it around 60-65 mph and you'll get great freeway mpg. If you're racing with BMWs then you're going to get more like 27mpg. But of course the gas guzzling BMW X-5 SUVs will only get around 11-15 mpg in that fast mode! I test drove one, and that's what the display said I was getting. I live in a hilly area in San Diego with a lot of canyons, and it's going up the hills that can really cut in to your fuel economy. One thing that's helping my mpg right now: It's warmer weather, and consequently the gas engine doesn't come on as frequently. I also paid around $50K for my RX 400h, and I bought it about 1 year ago, July 2006.

I am really attached to the 400h. I asked for a vanity plate for my birthday. It came in two days ago. KIKNGAS Purchasing a hybrid was also a statement. I felt if one life could be changed or a step toward energy change be met, I might be a small part......I don't feel I gave up a thing. My "fun tickets" are well worth the experience with this car.

The person who wrote the NYT origional 400h review was not fair to the vehicle and angry with Toyota that they wouldnt provide a second comparison car for him to drive. He went on to write the review anyway. Many of us complained to the NYT editorial board to no avail and im surprised Toyota didnt pull their advertising from this paper. These hybrids have great reliability and 85% of 400h owners would purchase their car over again. Many reviewers and people in general miss the fact that the toyota hybrids are always regenerating energy thru the brakes no matter what the mpg, and are always low in emissions. Yes you do have to drive in a hybrid style to get the best mpg, its not magic and requires some effort. Yes there is a winter mpg penalty, the batteries are more efficent in warmer weather. Premium fuel will result in higher mpg, you can use either grade.
 
The 400h has an extremely smooth CVT trans, electric ac compressor, and power steering, immediate power at any
speed range and to me is a better driving experience than an rx 330 or 350. Once i drove the hybrid would not go back to the others.

Carguery, you said it very eloquently.
