Tires & Speed Rating

I have michelin harmony tires on with an "S" speed rating. I went to buy a replacement, and the tire dealer only had an T or V rated tire in that model. He said I should not buy that one b/c it was bad to have a different speed rating on one tire versus the other 3, in terms of traction in rain/snow.

Is this true, or is he just trying to get me to buy 4 tires instead of 1?????

I own a 2003 Kia Sedona... On Saturday, after releasing my parking brake both my headlights burnt out. Is it a fuse issue or actually burnt out headlights??? ThanksRead More

How do you know if it is the battery or the charger?

We have this battery powered floor scrubber machine where I work. It is has 2 large 12 volt batteries up pos.---------> neg., to stay 12 volts. The other day it smelled like rotten eggs in the room, and I found that the batteries had the water cooked out of all the cells equally well. Lifting the machine's lid out of the way exposed bubbles coming out of the cells, and the enclosed area (now opened) was quite warm. 12 cells in all. I used 5/6 gallon distilled water to refill them. Then plugged in charger. The next day, I smelled the sulfer smell again, only not AS bad. Liffted the lid again. Water levels down SOME (1/4-3/8ths inch maybe. Not dry cells like the last time). Added water. Voltmeter right after that said about 12.4 volts. I was expecting less actually, but that is what she read. Then I plugged in the charger. The charger, included in the machine, has a nice big digital printout of the amps, and above that are 3 pictures of a battery in 3 stagers of charge: The left picture shows battery almost empty, middle being halfway charged, and right one shows fully charged. A red indicator light is over each picture. Well, after plugging in the charger, the digital kept climbing to about about 12.5 amps (amps, not volts). But then within about 15 minutes it came down to 9.1 amps. The indicator light on the charger remained at the left red indicator light showing low battery. Then I did a voltmeter check during as it charged at the 9.1 recorded amps, and was nto coming down any more, and I got 14.4 volts. Note that below the digital printout is a large number 5 printed on the charger, and I'm wondering if that means you can expect a good battery, when fully charged, to come down to 5 amps? Then I unplugged the charger and it read 13.06 volts. So what do yo think is going on? Do you think the batteries acts like they have a hole in it?, and keeps taking a charge?, to where it can never drop the amps towards 0 or 5?, and stays at 9.1 amps? Or do you think the charger is malfunctioning, and keeps on charging, when it really should be going over to the right indicator light and shutting itself down, and isn't? I am actually not the one who works on this machine. I intervened after talking to the janitor who runs it and adds water to the batteries when needed. Tonight when I called him up, he said he used to only have to add water to the batteries maybe once every 6 months. And he ALSO told me that he ususally would hear the charger's fan-motor run at first, but then later after it charged, he would no longer hear it (an indicator to me that the charger was shutting off to protect the batteries from over cooking.) Where instead,*I* caught the charger that 2nd day still running with the fan going. Batteries?, or charger? Place your bets here.:)Read More
