  • Matrix99:

    Sounds like a trip to the dealer is in order, since this is definitely not how they are supposed to work. They should come on at reduced brightness until the sensor on the dash detects low light level. At that point, they should begin coming up to full brightness. However, the taillights should come on only when you turn on the switch.

    It wouldn't explain all of the symptoms, but covering the sensor (driver's side top of dash) would cause the lights to be at full brightness all the time.

    I'd like to ask the new owners if they plan to add any body side molding to protect the doors and the beautiful sheet molding of the Matrix?

    If so, where would you purchase the molding?
  • Degaled,

    I seem to remember reading somewhere that you go the nav system. Could you tell me if the CD changer in your XRS is a Pioneer and if it can play CD-Rs?

    A lot of Celica owners have removed the butterfly valve from their engines. The increase was dyno'ed (sp.?) at 3 hp, 4 torque. I'm guessing this would work on our cars, too, or at least the XRS.

    The base stereo in the Matrix will play CD-R's but didn't seem to like the Verbatim CD-RW I tried. Every CD-R brand I have tried has been fine though.
  • I still need to verify the cd changer but that makes me think it will work. I've read on Usenet many posts saying that Pioneer do read CD-Rs and I'm pretty sure that I read "Pioneer" on the front of the CD changer of the XRS I saw.

    Okay folks, here's the skinny on sizing tires: Whatever tire combination you choose, you're goal should be to maintain an equal circumference.

    Now a few different sizes have been mentioned, however some are incorrect. Here are sizes which are considered comparable:
    17 in 215/50 = 16 in 205/55 = 15 in 205/55 or 195/60. The optimum size for 15 in tires is 205/55 because you're overall circumference will have the smallest differential at this size. However for winter use, I'd recommend 195/60 because of its narrow width. Remember, with a smaller foot print, your tire will cut through the snow better. Hence you'll get better grip. In the summer, the opposite is applies. Get the widest tire you can get! Good luck!

    Hey alshariff

    I am a bit claim "17 in 215/50 = 16 in 205/55 = 15 in 205/55 or 195/60." How could a 205/55x16 and a 205/55x15 be equal in height? There is an inch difference in diameter in the rim.

    Also, could you tell me what the 15" eqviualent would be to replace my P205/55r16 factory tires? Deagled and I thought P195/65r15 would be the cats meow...

    thanks for your help

  • deagleddeagled Posts: 20
    Alshriff, where are you getting this information?

    You are right when you say you need to maintain an equal circumference, but the sizing you suggest is incorrect. Perhaps you know something I don't (insert joke here). I know from experience that to go from a 17 to a 15 (for winter tires for example) you need to go 205/65 15's. this keeps the diameter at 25.5 inches and the circumference at 80.0 (give or take a mm). This setup would only throw your speedometer off 0.1% (slower).

    Please help me understand why/where you got these numbers.

    Here's a useful link:

    195-60-15 seems to create less speedometer error.

    Hi folks,

    The tire sizing site's pretty good. Thanks TUP!

    Here's how I came up with my tire sizing:
    215/50R17 = 323.4 mm Radius
    205/55R16 = 315.9 mm Radius
    205/55R15 = 303.2 mm Radius
    195/60R15 = 307.5 mm Radius

    Obviously these figures are all different, however the matrix is set up to run 205/55R16 tires. The 215/50R17's are a size up and the 195/60R15 are a size down. Both deviate less than 9 mm from the 205/55R16. When we look at a tire, 9 mm can easily be eaten by tread wear, inflation pressure and temperature.

    I admit, I was smoking some pretty cheap stuff when I typed 20/55R15 (because thats probably pushing the envelope of error). All in all, as long as gauge error is kept below 10%, you'll have whats considered a capable gauge. This is you should always fight your speeding tickets!

    Thanks for clearing that up for me.

    For all of you bike/canoe/boat transporter types out there, who maybe like me have a Thule rack which will not fit a Matrix anymore, Thule
    do have a solution now, they are just not telling anyone about it.

    Thule now make a TP Top Track to fit just about any vehicle including the Matrix. If you go to http:\\ now and use their fit
    guide you are told there is no roof rack solution for a Matrix, but you do have this option. You need to bolt to the roof so my suggestion would be to have your dealership do it...but for $120 USD you can bolt this setup rail system to your roof and then connect your existing Thule components to it (providing you have the right
    connection feet).

    The ad also claims it accepts Yakima rail riders as well.

    I thought I would share this because I was just about ready to sell my entire Thule Rack system and purchase an entire Yakima system...this rail system is saving me hundreds of dollars...

    XRS 6spd...1450km and counting...

    Just bought 2003 Corolla LE and was wondering if the undercoating offered is worth the investment. Have previously used Rust Check and it saved previous vehicles. Most dealer applied materials actually seal in water and salt increasing damage rather than preventing. Rust Check uses an oil like substance that remains liquid. Any opinions?
  • dogtrainerdogtrainer Posts: 96
    One of the things I don't like about the Matrix is the restricted vision to the rear when backing. To resolve this problem, I'm considering having a backup aid installed. I've heard good things about the Puron systems. Anyone have any experience or know where I can get one? Their web site doesn't list the price or give dealer names.
  • matchrevmatchrev Posts: 1
    I'm just curious: Do the 16 and 17 inch wheels/tires on the Matrix fit on a 2003 Corolla? Are the bolts/offsets the same on these two vehicles? I know that the Corolla now uses 5 bolts.

    I'm thinking going aftermarket would be better, cost-wise, though. . .
  • dogtrainerdogtrainer Posts: 96
    I don't know if they are compatible, but I'm certain you could save money using aftermarket wheels. Suggest you check out Tire Rack at

    The right arm rest on the drivers side (the one that is the access hatch for storage) on a 2003 CE Corolla has no cushion for your arm/ elbow. This bothers me since I am skinny and have no meat on my arms!
    Toyota at least put a cushion on the driver door for you left arm!! Does anyone know where I can get a modified hatch so my elbow does not get inflamed? Thanks.
  • bryanf1bryanf1 Posts: 2
    I have a corolla S, and was wondering if using the tire size 225/50-16 would be alright? Also, if you go to, you notice that the size of the tires are different then what is already posted on this web page. They say that you need a 55 sidewall, when this page says that you need a 50 sidewall on a 16" rim. Does it make that much of a difference?

    Has anyone found a good source of discount Toyota Acessories on the web? I found a couple, but I think I can do better based on past experience with Honda Odyssey acessories. If it violates the current rules to post links, please e-mail me.

  • dogtrainerdogtrainer Posts: 96
    What're you doing on this board? Did you buy a Matrix to go with your Odyssey???
  • tom3ktom3k Posts: 91
    I bought a '00 Odyssey 2.5 years ago. It is still going strong as the primary kid mover and Mrs. 3k's main vehicle. Thanks to Edmund's Town Hall, I was able to not only find a decent price on the van, but find sources for deep-discount accessories and the factory extended warranty. (which you oughta remember dogtrainer!;-) Unless, of course I'm confusing you with someone else.)

    I was hoping to do the same for my new Matrix, which I indeed now own and will be my daily driver (the Integra and the Escort SW died in rapid succession).
  • dogtrainerdogtrainer Posts: 96
    Nope, you're not confusing me with anyone else, it's the ol' COOT Cop himself!

    To get back on subject...try these if you didn't find them yourself: and I don't think either is as good as HandAparts, they sure don't have anyone like Trevor giving out free advice! Be sure to post any others you come across.

    Problem is, the Matrix is still so new there isn't much aftermarket stuff yet.
  • tom3ktom3k Posts: 91
    I'm just looking for the factory mats (probably all-weather) and the bumper guard (functional, and looks really cool against the red paint). Mrs 3K has already put the kibosh on new wheels or an upgraded stereo (and they complained about the Odyssey stereo! You should hear this thing!), so I'm nearly done.

    When I bought the car, I just wanted to get it off the lot and home before they changed their mind on the price (just under invoice), I didn't ask about accessories and neither did they. When I went in today to give them the loan check, I asked the parts dept. what they wanted for the mats, and they quoted me over MSRP ($106 vs my best internet price so far of $68)!

    It was also a week-and-a-half special order for red touch-up-paint (got a chip on the way home, pre-Zaino :().

    According to this "Tire Calculator" at (, the tire size 225/45-17 will work just fine on my corolla, because the stock tire size is 195/65-15. I am just checking to see if this calculator is all that accurate.
  • 8u6hfd8u6hfd Posts: 1,391
    225/45 r17 is fine

    (I deleted my tire size post, because I finally noticed the typo)
  • dogtrainerdogtrainer Posts: 96
    I agree, the bumper guuard looks really good on the best color, Radiant Red! Also helps to prevent marks when loading stuff. Have you checked to see if MacNeil Auto has Weather Tech mats for the Matrix yet? I can't get to them myself because something on their site keeps crashing my browser.
  • tom3ktom3k Posts: 91
    MacNeil does indeed have the mats for the Matrix on their site (which my browser survived, BTW). They are around $20 more than the best price I can find for the factory all weather mats. Are they worth it? What are the advantages?

    Shouldn't we be referring to the color as 'RR'? Is ti the matrix equivalent of GG?;-)
