Which wheel is the power wheel?

I've got a quick and simple question. Which wheels transmits the power, the passenger or driver front? I had to replace a tire due to a bulge in the sidewall and therefore put the new tire on the passenger front. When Acura replaced my brake pads under a TSB, I noticed they took the new tire and put it on the driver side. I'm trying to figure out if they just slapped the tires on and didn't care or if they put it on there for a reason. Thanks .........

Drive Wheel

On all FWD Hondas (except for those with an LSD), its the right-front wheel that is the drive-wheel (passenger-side).

I'm confused? What is a "drive wheel"? I thought both fronts were drive, but you say the front right?

Jack up the Entire Front End and Put it in Gear and Test it out.

on a surface when both wheels have equal traction, BOTH wheels supplies power!!

Else your car will be running in circles all the time...

Cars with LSD allows the transmission to rotate both wheels in the same direction with equal power. Cars without LSD, the transmission will only turn one wheel, and the other wheel gets turn throught the drive shaft by the "drive" wheel. That why NJ said that if you jack up your car, you can see the difference.

Does this fact contribute to why high power FWD cars have torque steer?

on a car with an open differential meaning all hondas except those with LSD the wheel with least traction is the drive wheel..it changes the right or the left ...if youd like proof id be glad to show you both sides of my car covered in melted rubber.....

Jacking up

Jacking up the car won't really work sometimes... just go do a burnout on some water (with the parking brake up)... you'll see real fast. The NON-drive wheel will stop spinning all of a sudden

There is only ONE wheel that's the drive wheel... its nothing to do with traction... its got to do with the diff.

ill say it again...the open differential sends power to the wheel with least traction....sometimes you'll spin the left one and sometimes you'll spin the right

The Quaife torque biasing differential enables your car to accelerate quicker and corner faster. How?

By getting the power to the ground!

The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

There sure seems to be a lot of confusion over this issue.

In the usual ordinary (non-LSD) differential, the power wheel is the one with the least amount of traction (resistance) available. If one wheel is on a slippery surface then that one wheel will spin. If the wheels are on a surface of equal quality then both will get the power. I'm sure plenty of folks have seen burnout marks from BOTH wheels.

With an LSD the wheel with the most traction gets the power. Once again, if the wheels are on the same quality surface then both will get it. This can be evidenced when applying power in a curve. As the inside wheel unloads more power is transferred to the outside one. In a non-LSD situation then the inside wheel would start to spin.

If a non-lsd car is in the air (on a lift) you can get either to spin by simply holding the other with your hands. Don't try this with an LSD equipped vehicle as you will be severely injured.

Geez, I thought this was going to be a simple question! Shows what I know. I guess I'll just leave the tire where it is .......
