Rear wheels "toe in"
 

Why am I seeing this on nearly every 1/10 scale car? I see it on nearly every on road and even my Axial EXO Terra buggy was like that. I straightened them out on the Terra buggy and found no change in performance. I have a new TT01 type that is not like that, the wheels are straight and it runs great.

Why are they toed in?

makes the car pull in a straight line.

Meaning what exactly? I don't get the theory. I'm sure the car makers have done their research which is why so many are like this. I just don't get it. I always thought a car with all 4 wheels perfectly aligned would track straighter. Is this a feature mostly seen on entry level cars? Because I have seen plenty of cars that don't have this. Many are high dollar.

I didn't write this. stole it from another forum. copy and paste.

Toe is the angle (inwards or outwards) that the tires point when the wheel is straight ahead. Toe-in means the front of the tires point inward, and toe-out means they point outward. Zero toe means the tires are parallel to each other. The biggest effect toe has on the handling of the car is on stability. When a car hits a bump or enters a corner, forces on the tires act to steer the car off to one side, making the car unstable and difficult to control. Toe-in counteracts this, improving stability. Toe-in also causes understeer during initial corner entry. Interestingly, toe on the rear wheels has the same effect on handling as toe on the front. Toe on the rear wheels is useful for tuning the handling of the car as it is exiting corners.

Front Toe "IN"
Slower steering response
More straight-line stability
Too much will casuse greater wear at the outboard edges of the tires

Front Zero Toe
Medium steering response
Minimum power loss
Minimum tire wear

Front Toe "OUT"
Quicker steering response
Less straight-line stability
Too much will cause greater wear at the inboard edges of the tires

Less Rear Toe "IN"
Less straight-line stability
Less traction out of the corner
More steering
Higher top speed

Intermediate Rear Toe "IN"
Intermediate straight-line stability
Intermediate traction out of the corner
Intermediate steering
Intermediate top speed

More Rear Toe "IN"
More straight-line stability
More traction out of the corner
Less steering
Less top speed

An exact line from my post. Something tells me this is a spam bot.

I looked at his posts. He doesn't add anything to the subject being discussed. Don't know if it's a bot or just someone trying to up their post count. If it's a bot they'll get him.

Big Alice basically covered it, Wear and tear has a lot to do with it as well
