Now point your feet out. Go show off your new knowledge to your friends. If the total toe is off, severe tire wear can result. You see, proper toe settings make it possible for the least amount of resistance to occur when your tires spin. Did you know? Toe problems are the leading cause of most tire problems and tire wear. Having your alignment performed as recommended approx. Less tires replaced, more money in your pocket.
Blog Categories Blog Home. Alignment Settings The following settings are dependent on the intended use of your vehicle and manufacturer recommendations. What does Camber mean? How does camber differ for different types of vehicles?
How does suspension affect camber? What does caster do for alignment? Toggle navigation. What is Camber? Positive Camber - When your wheels are tilted outward, the vehicle has improved stability.
Negative Camber - High performance vehicles that require better cornering tend to use negative camber, because it gives the driver more control in this regard. What is Caster? Positive Caster - If the line slopes towards the rear of the vehicle, then you have positive caster. The down side to positive caster is if the vehicle does not have power steering.
In this case steering effort will be increased. Caster settings are not a primary, direct factor in tire wear. However, excessive positive caster in association with other alignment maladjustments can exacerbate a tire wear issue.
For example, a tire wear pattern called feathering can result from a combination of too much caster with incorrect toe settings. Tire feathering is characterized by a high-low, smooth-sharp variation in the wear pattern of the tread blocks. Of all of the alignment settings, however, caster is the least likely to be a cause of uneven or abnormal tire wear. Arthur Krebs and his positive caster concept!

For racing, it depends on the type of car, tyre and wheel geometry.
For a rear-wheel drive car, negative toe at the front wheels and positive toe at the rear wheels is quite usual. We see this mostly with front-wheel drive cars, but it is also found with rear-wheel drive cars with independent wheel suspension. When releasing the driving forces, the momentum of the drive shafts causes the suspension, as well as its joints and connecting components, to be subjected to a high load.
This will lead to distortion of the suspension's construction. The driving wheels want to go forward and will get positive toe. This especially applies to street cars. By applying flexible rubbers for the purpose of comfort and noise reduction, there is a lot more movement in these types of suspension.
Which is why static tracking often starts with some negative toe. High toe-out values will lead to the inner edges of the tyres being 'eaten', which will lead to additional wear and tear. A lot of toe-in will especially subject the outermost part of the tyres to a high load.
Negative toe will mainly improve the steering response. Positive toe will mainly increase the straight line stability. Sometimes toe-in or toe-out is applied for a different effect: tyre temperatures. It is very important for racing tyres to reach a proper operating temperature, in order to ensure maximum grip and performance. When tyres remain too cold, the so-called scrub effect of tracking may provide a solution. This scrub effect also has a cleansing effect on the tyre tread.
This means the brakes can be applied more forcefully and there will be more grip available in the corners. Passenger cars are mostly set up with toe-in positive toe , as the steering behaviour is then sacrificed for straight line stability. For race cars, steering behaviour is more important than straight line stability, so toe-out negative toe is preferred here. In case of independent wheel suspension at the rear wheels, toe-in and toe-out also apply.
