Interesting, that changing tires creates such a significant speedo/odo difference. My new GT came with low-profile tires, and my speedo reads 4-5 mph fast at freeway speed. I see 65 on my speedometer when I'm actually traveling at 60. This is per three different tests: driving behind my husband as he goes 65; looking at my Tom Tom; and readings from two different dealerships. Shouldn't the manufacturer have the instruments calibrated to match the tires their vehicles come with? And can this be fixed? It's a little distracting, trying to figure how fast I'm actually driving, when the dial could be off by only 2 at 35 mph or off by 6 or 7 if I'm going over 65. |

| DOES ANYONE KNOW IF THESE TIRES CAN BE REPLACED WITH REGULAR TIRES? THE RIMS ARE 18", AND THE RIDE IS VERY ROUGH. | |

my nephew has a -06 base vibe,auto,windows,locks,..not the cheapest,but not quite the gt.. ..he's wanting to put the 17" gt rims on it,replacing the stock 16" ones,so i'm reading up on what y'all are saying as far as issues. -i see where some are complaining about speedo reading wrong,and can tell you,as a former grease monkey for pontiac-back during the trans am-burt renolds days.. change the gear drive in the transmission..should be almost a do it yourself job with these front wheel drive cars,as i don't think you'd even have to get under the car,as i did with the trans am's.. -go to the service/parts department,-with your tire size,and ask them for the correct toothed gear for your vibe and your tire size..they should have a chart..if not,you'll nhave to experiment..but by changing that gear-witch is done by following the spedometer cable to wherew it hooks into the transmission..the cable threads on-not unlike the coax on your cable tv hookup..there should be a clip holding down the gear..usually only one bolt..don't unthread the cable,as you'll need to pull on that to get the gear out.. -the gear should be about the size of your thumb....the way they index them is by color!..and each color will tell you how many teeth it has.. --if your speedo's reading fast,put in a smaller gear-usually with one less tooth..if it's reading slow,put in a gear with one more tooth!!--it's only a little plastic gear,should only cost a couple of bucks($3.00 in th -80's)so,even at the dealer,youn should get outa there for less than a jackson-for the parts,at least!! THANK YOU, THANK YOU!! PLEASE ! ! !NO APPLAUSE, JUST THROW MONEY!!   SERIOUSLY,..this should fix your speedo's readout problem.. -i learned this lesson the hard way,i pulled the speedo out of the instrument panel(not a easy job),and took it to the parts counter-for either repair or exchange..they got a BIG laugh out of the stupid kid,and THEN told me about the gear thing..i wasted a entire day-doing a job that should have-and only paid,less than a hour,but i never did that again!! |
