Prius (Gen 3) :: Lower MPG With Aftermarket Tires


Dec 8, 2014

I recently replaced the factory Yokohama 195-65-15 on my 2011 Toyota Prius II with a set of Michelin Defender. MPG has dropped to 45 mpg for city driving. With the Yokohamas, I was averaging 49 mpg.

Prius C :: Lower Tires Pressure Can Affect MPG?

I have a feeling my 2012 C 3 may have low tire pressure. One of the tires looks kind of softer. Is there an indicator that warns when it happens?

How in general do I approach this? For the past few weeks my mpg was low, barely making it into low 40's. So, I wonder if the tire pressure can affect the mpg.

Gen 2 Prius (Audio/Electronics) :: No AM Reception After Installation Of Aftermarket Radio

So I just installed my Pioneer 4400BH - Took several hours and all went well - EXCEPT - no AM reception after I installed the radio. FM seems fine.

Two possible guesses:

1. Did not push the antenna connector in far enough.

2. Gen 3's use an antenna amplifier. I did not think that Gen IIs used on so I did not connect the Power antenna lead to anything.

Passat (B7) :: Adding HID To Aftermarket Fog Light Setup

I'm ordering the parts to add fog lights onto my TDI SE and want to increase the light output so that I can drive with the Audi style LED headlights in the parking light setting with the fogs on and still see where I'm going. I have a few questions regarding the setup:

1) Since it is an aftermarket setup on my SE do I need to get a CANBUS HID kit or a regular one?
2) I know there is an increase in light output when installing regular H11s in place of a H8 bulbs. Is it the same with an HID setup?
3) I'd like to find an affordable 5000k HID kit with decent quality.

Camry :: Aftermarket Wheels Making A Grinding Sound

I have a 2011 Camry LE with American Racing aftermarket wheels. I had the car serviced last Saturday for its 70,000 mile check. When I got in the car to drive home, I felt that somehow the car was making a different sound and did not "feel" right. I did not drive the car for a few days, but when I did the left front wheel was making a grinding sound, checked underneath, for any kind of debris I might have picked up. Nothing. I took it back to the dealer. They put the front wheel on the back and the noise and vibration were gone. They said it was a defective hub on the rim. Then tonight, coming home from work, the right side was making the same sound or worse. I pulled into a tire service center, had them do the same to that side, and the sound and vibration stopped. A friend thought it might be the weights have moved and due to the tighter spacing on the front wheels they are hitting the calipers as the wheel moves.

Touareg :: Installing Aftermarket Amp Using Factory Nav Line Outputs?

I was unable to find any posts talking about using the radio's line out (non-amplified) signal to send to an aftermarket amp. Any links or info would be great as I plan on performing my install soon and I really want to avoid using a line output converter (on the radio's amplified outputs).

Lexus GS 2006-11 :: Plastic Connected To Aftermarket Fog Light Started To Melt

I put aftermarket fog light bulbs and after a while I realized that it was melting the plastic piece that that bulb connects to. I realized it when my light went off then when i play with the socket it turns back on which is a bad connection. I called the dealer up and asked what do I need to do and he told me that I need to change the whole entire wire that connects from the harness, which will run me about a grand.

Golf IV / Jetta IV :: Aftermarket Radio Installation Lead To Trunk Light Lit Up

Installed aftermarket radio with no problems in 2006 Jetta. Ironically, now the trunk open light is lit on dashboard even though the trunk is definitely shut and the horn wont beep when locking with the keyfob although the doors do lock. I researched here and found some had to push their radio (oem radio) in a little bit to make contact with "microswitch?" and then horn worked..

Im not sure if its that car thinks trunk is open when it isn't or that it thinks the radio is stolen (when it clearly isnt, just an aftermarket) one and thus won't actually arm the alarm..........however, doors are locked, and red light blinks in the door as well as the exterior visual confirmation of alarm being on.

Yaris/Scion & Vitz :: 2000 - Fuse Blown While Installing Aftermarket Stereo

I put in an aftermarket stereo. It has been a while since I have done that and somewhere along the wiring process I made a mistake and blew a fuse. I knew the lights around my speedometer weren't working but what I didn't realize is that my running brake lights weren't working, it took me about two days to realize this.

I fixed my wiring mistake and started looking for the blown fuse. I found one (I believe #19 inside the vehicle) and replaced it. This fixed my running brake lights and half of my instrument cluster. The lighting on the right side of my speedometer seems to work but to the left of it seems to be no light.

Also, I have an automatic car starter and before I jacked things up when I use to start it and the blinker lights use to come on and let me know that my car was running. I have checked the majority of the fuses(I believe all of them) and it doesn't seem that I have anymore blown fuses.

Lexus RX 2004-09 :: Aftermarket Key Won't Program - Driver And Rear Window Buttons Are Flashing?

I just purchased a 2004 rx330. I purchased a set of keys off amazon and tried to program them using Techstream. It will not allow me what so ever to program. it always gets to programming the key step and then says error between key and ecu. I have programmed tons of toyota keys using techstream and never had any issue with aftermarket keys so I bought another set from another vendor and they will not program either. I was able to manually program the remote for keyless entry so they will communicate with the car and are the right FCC ID number. I used to be a service advisor at Toyota so I do know more than the average person when it comes to these.

Also the power window master switch will not roll down the drivers side rear window or do auto for the drivers window. I have tried every combination to reset (we used to do them on the driver sometimes) and it still wont work. Drivers and drivers rear window buttons are flashing.

Would bad lower front ball joints freeze and creak when turning. I have noticed that my car(2010GLS) with 108k miles has a creaking sound when turning the wheels left to right.

Tires - Gti - Volkswagen :: 2009 - Low Profile Tires Keep Blowing Out?

I just bought a used 2009 VW GTI which is a lovely car as you can see from this picture:[URl]. As you can also see from that picture I live in one of the many snowy states. The roads now resemble the lunar surface except with deeper craters and potholes. When I bought the car, I was stupid enough to be talked into a $500 5 year warranty. Or was I? I've driven the car for almost a month and have replaced 2 tires due to pothole damage. At this rate, I'm way ahead on the warranty. The car has 18" low profile tires which seem sensitive to being banged into the rim of potholes. Is there something about my driving that's causing this issue? I don't really speed and the last blowout happened at around 30mph. Is this something I just have to live with? Can I replace the tires w/ normal tires?

Ford Super Duty (1999-2016) :: 2015 F450 - Add Sync System With Steering Wheel Controls Or Aftermarket Radio?

I recently got a 2015 f450 XL service truck and was wondering if the factory sync system with steering wheel controls could be added or would I be better off swapping in an aftermarket radio? And the remote start, fog light and brake controller kits are the same from the pickups to the chassis cabs correct? Last question is that I found the truck has global window open but doesnt remotely close is that correct?

Gen 2 Prius :: Bumper Lower Lip Loose?

When I was spray painting my bumper lower lip. Wiggled it loose so I could tape better but it came loose. This is what it looks like after gluing back together. The issue is with the little rubber trim not wanting to stick and looking ugly. Had a few ideas.

1. Replace with factory parts and repaint.

2. Wide pin striping along the line,blue or black.

3. Reflective tape square.

4. Euro fog lights

5. Long LED strip,either red or white

6. New blinker/reflector

7. Putty/bondo the bumper to look like one piece then paint.
