Prius V :: After Changing Tires Mileage Drops?
Jul 28, 2012
Other than during cold winter weather, our 2+ year old Prius has been averaging 51-56mpg all around. Our tires needed changing and my spouse went to a tire dealer. The dealer recommended Cooper tires, a model supposed to get 50k miles. Almost immediately we now average 45-46mpg.
In looking back, we didn't buy tires that accentuate mpgs. Is there anything we can do short of selling the tires? And are they makes and models we should think about when it's time to change the tires?

When I bought the car in 2009, if I had 4 bars on my traction battery at night, it would have them in the morning. Now I can leave the car for 2 hours in moderate weather. When I drive off, it will show 4 bars but driving in eco mode w/o ac, it will drop to 2 within a mile and stay there for several miles before it starts to charge again. My overall fuel economy has dropped 10%.

This Easter I put summer tires on my "new" (owned about 4 weeks) prius -07, and cleaned and greased brakes.
With winter tires (almost new Nokia hakka xx, stud less) I got 4.5 l/100km (52mpg) easy and 4.2 (56mpg) at best, now I get 5.5 (42mpg) and 5.3 if I struggle, if I relax and put cruise control on I get 5.8 (40mpg). I travel 100km to work every day.
Summer tires is Michelin primacy (about 2 seasons?) pumped to 3.0/2.8 bar (over inflated).
Brakes don't seem hot after drive and they was really clean and easy to move after my service so my guess is that they work fine...
Mileage went down over the weekend so I see a clear link.
It was more fun trying to hypermile at 56mpg aiming for 60 then it is at 42 aiming for 45...
12v battery charged, just in case. Still same temperature out 1-8 C. Oil and all filters changed first week (will change trans axle oil in summer). Travel to work got 4% shorter so tire size must be a small reason to the +20% problem.

Last October I needed new tires, so I had Michelin Defenders put on my 2011 Three in place of the OEM Firestones. The Michelins perform well and are nice and quiet, but...
My gas mileage (both indicated on the dash and calculated) has dropped by about ten percent. In researching the two brands of tire, I found that the OEM Firestones are rated at 836 revolutions per mile, and the Michelins are 839. I'm wondering if this is the reason for the apparent change in mileage.

I own a 2008 Prius and I have been taking it to the dealer for service because it seems like non-Toyota shops don't know how to economically service the Prius.I'm seeing that the dealer I go to also seems to want to change the filters and rotate the tires at every service and this really increases the cost well above a normal oil change price.
How often have people really been changing the engine filter; cabin filter; and rotating tires? How often is this really necessary? I'm at 108000 miles now.

The steering wheel mysteriously clocked itself slightly to the right after changing out the standard tires to same sized studded tires for winter. This has never happened before and I was unaware of any alignment/wheel clocking problems up to driving into the shop to swap out the tires on the wheels.
Air pressures were all good and even all around--but I don't know if they were even before the change-out. Also, the wheels were balanced and the drive afterwards revealed no pulling either way or vibrations. On top of that neither the tire store nor my Toyota dealer had any explanation(s).
I'm only guessing at this point that prior to studded tires there might have been a clocking error so slight it was not perceptible in over 5K miles and with the studded tires now it is perceptible.
Q: Is it possible under my circumstances for a different set of tires on the same wheels to make this sort of difference?

I have a 2011 Camry LE with about 13,000 miles on it. I just replaced my tires with Bridgestone Turanza EL400 225/65/16 and now my mileage have drastically decreased, I used to get about 400 miles per tank driving strictly city, but now I'm lucky if I can actually reach 300 miles driving under the same condition (non aggressive city driving). Does increasing the width of the tires actually make this big of a difference in mileage?

I have heard that many people are switching to the nitrogen in tires as it is to improve gas mileage. I know they offered it at the Lexus dealership, but I never took advantage of it.
Of course, the phaeton is not going to get the mpg as an echo or aveo even with the tires, but I am just curious...

The stock 265/75/16 tires need to be replaced and I was considering swapping 285's on the stock wheels. Will I notice an increase in fuel consumption? I realize that calculating mpg will need to be adjusted due to larger tires since the speedometer will be slightly off.

I was getting 10.5 MPG in my 2003 dodge ram ST, It has 33 in tires and a 4.7 engine.
It was missing a bit so I code checked it and 4 plugs were not firing. I got the new plugs and a 3 ft extension for my 1/2 in ratchet and after an hour I got the old plugs out without taking the threads out with them. I bought it used and the plugs looked like they came with the truck.
Now I'm getting 9.3 MPG. runs good but what can cause the thing to lose mileage?

just picked up a 2012 F-250 6.7 XLT. I won't be driving the truck too often, probably no more than 5000 miles a year, and was wondering how long can oil last time wise. I would wait for the change oil indicator to come on, but was wondering if it's takes a year or so or what. Was probably thinking changing it out once a year regardless of low mileage. I have the service plan from my dealer for 3 years which they threw in but it's for 7500 mile intervals so maybe I can work something out with them. Def love the truck and now I hate having to drive my other vehicle as dailys.

As the weather has been getting warmer lately, I'm about to change over to my summer wheels and tires. First, I'm just wondering when most people who use winter tires on this forum make the change.
On my previous cars, I've just changed over in the fall and spring by myself unless I needed a wheel balance or alignment. With the harsh winter and roads we've had this year, I'm thinking maybe I've hit too many potholes, since I'm noticing a vibration at 140kph (87mph). I got the current OEM rims and winter tires new last October and had them balanced before installing them on the car and I hadn't noticed anything until about 2 weeks ago. The issue did not suddenly show up after hitting a pot hole, but just started happening and becoming a bit more noticeable recently. The weird part is that it seems to be happening only at that specific speed when accelerating, which makes me wonder if its the wheels out of balance or engine/turbo vibrating under load. As you can imagine, if you let off the acceleration at high speeds, the car slows down slowly and the vibration goes away. So it's hard for me to say what the problem is.
When I switch over to the summer wheels and tires, I'm thinking of just changing them myself to see if the same vibration still occurs at the same speed and then deciding on whether to get them balanced or not.
A related issue, which I think some others have posted about on this site has been the wheel alignment. In the last 3 or 4 months, I've noticed that the car has a slight pull to the left under no steering input, so I may have to do an alignment soon.

My wife has a 2007 Toyota Sequoia with only 17,000 miles on it (as of Mar 2013). It has had regular scheduled maintenance - engine oil changes, etc. However, due to low mileage, it has never had Transmission or Radiator fluid changed. All miles have been in town, short trips. Is there a need to have these fluids changed just due to the age of the Sequoia and type of miles driven. It is an expense I would rather not do unless necessary. We do plan on keeping it to well past 100,000 miles. Considering the age and miles, is there anything else that I should be watchful for or take action on?

I have a Hyundai Sonata w/ P215/55R17 tires.
I am almost due to get new tires and my husband says that we should switch the wheels and get regular tires, not the lower profile tires that were OEM w/ the vehicle. The current tires are expensive and regular tires would be less expensive in the long run. When I asked at the dealership 6 mos ago they said that it would not be good for the car and would adversely affect the performance. If I do change, what tire size (regular sidewall height) would be appropriate (and less expensive)to change to?

I've had my XB 5-speed for nearly a year and 10000 miles. It as been dead on reliable and fun to drive. My gas mileage has varied from 26 to 31 in mixed driving and from 32 to 35 on the highway. I use premium fuel only because I can get it without ethanol. My fuel mileage also increased a couple of mpg due to getting the power robbing ethanol out. True it is probably not enough to offset the extra expense but I like not having the stuff in my car. My only dissatisfactions has been with the transmission gear ratios. They are way to low. This torquy engine could easily do with a ratio that would drop about 500 rpm for more relaxed highway cruising.
As it is, though, my XB will go up any hill or long grade without breathing hard! Another is the instrumentation. I don't mind the center mounted set-up but speedometer and trip meter for mpg ratings are both inaccurate. My speedo reads about 2.5 mph high and the fuel mileage read out has about the same error, also on the high side. I have the stock 16" tires. The clutch has a narrow engagement band and can be difficult to be smooth on. The car is fairly quiet, is comfortable and this years hot, humid summer has shown it has one of the best air conditioners I have ever experienced in a car. I thought it might be an electric unit rather than a belt driven compressor because there is absolutely no perceived drag when the compressor kicks on.

I recently bought a 2004 Prius with 104,000 miles on it. When I try to go up into the mountains I only get a few miles or up to 1,000 to 2,000 ft. elevation (from 300 ft. starting) and the battery level gradually drops from 6 bars to 1 bar. The red triangle light and check engine light comes on and the car speed gradually begins to drop even if I continue to press on the gas pedal. I have only gotten down to about 35 MPH from 60-65 mph before stopping and turning around. Within a few miles of turning around the light goes off and the battery goes back up to 6 bars and works good going down hill.
The dealer I bought the car from has been working with me to figure out the problem but so far we have not figured it out. He has replaced the main battery as well as the inverter/converter. The mechanic was with me on a test drive to the mountains and had his car computer plugged in while we drove and experienced the same thing. It gave the code for the catalytic converter so we changed the entire CC/muffler (one long piece) and still got the same code. The battery indicator on this car has never shown more than 6 bars. I personally think it has a bad "Gas Engine" or something wrong with the gas engine.

About to hit 130,000 in 20 miles. For the past 10-15k miles, I have been consistently getting under 40 MPG, about 36/37. Only can I get 40+ for a whole tank when I do mostly highway driving. Before, my tanks would average 42-48 mpg.
My battery is also doing some funky things, sometimes when I turn the car on for the first time on a new day, my battery will go from green or blue (the blue right before it hits green) and will literally drop to one or two slivers of red in 15 seconds. I took it in when it first started doing that and they did a software flash or update, something along those lines.

On my 2001 Prius, while driving down the road the red triangle comes on and the ICE drops down to idle and the car slows down to 29mph. If I floor the gas peddle the car may or may not pick up speed slowly but if I let off of the gas peddle the least little bit it will slow down to 29mph. If I stop and turn the car off and then back on the triangle is still there but the car runs fine. After turning the car on and off 2 or 3 times the triangle disappears.

When I got water drops on my side windows (from rain or frost), rolled it down then up didn't clean off the water. Even worse, all the water drops were untouch.
Is the same to your car, or it's just my car?
