Bias-ply Manufacturing

All NA tires use enhanced bias-ply technology to increase performance. As a characteristic of bias-ply technology, the tire’s contact surface works laterally and provides greater feedback to the driver. This greater feedback allows the driver to be closer to the edge of the traction circle more often, leading to faster lap times. To take advantage of the different performance characteristics of NA race tires, the car needs to be set up in a different way and it is not necessary to use extreme levels of camber or caster. This means that the contact patch remains parallel to the track surface at all times and improves the tires ability to transfer power and braking forces. It also means that your cars designed in suspension geometry has a better chance of performing correctly. The NA enhanced bias-ply tires can generate extremely high grip levels and can offer a competitive advantage against radial tires.

Compounds – Personalization

A huge competitive advantage from NA Tires is the personalization of its products. NA is specialized on personalizing the tires to fulfill the needs of different kinds of formulas, tourism cars, and sports cars. The factory can adapt and use different kinds of rubber and compounds depending on the specific needs of each racing cars. It can reduce the costs and increase the performance and durability of the tires.

 

TIPS

Right Pressure

As these tires are constructed using enhanced bias ply technology, air pressure and the resulting temperature play a crucial role in the responsiveness and performance of the tires. These can be the determining factors on the ultimate performance of the tire and the racing car. NA Racing Tires strongly recommends that your team establish procedures to track tire air pressures and temperatures and how they impact final performance. Your team should take setup notes on the ambient air temperature, track temperature, tire temperatures, the environmental conditions, humidity, barometric air pressure, etc…during all practices days. This data will help the team to compare the drivers’ performance in different conditions to better understand how the tires respond on that vehicle. Enhanced Bias Ply Technology Racing Tires react differently to tire pressure changes than radial tires and it is important to develop a tire pressure and tire temperature operating window for each car. Please contact us for recommended starting tire pressure points for your application and track. 

Alignment  

NA Racing Tires have enhanced bias-ply technology. It may requires a different car set up to maximize performance and tire life. As a general rule, the racing car should reduce the camber to 1 degree or less and the caster should also be close to zero. The tires will work laterally and will provide 100% contact with the track surface at all times. The tires will have greater adherence to the track surface and this will lead to increased performance on track. The enhanced bias-ply technology is the secret for the better performance, but it will require an adaptation of the car set up to allow the tire to work its best. These tires require suspension set ups close to stock or standard alignment settings for passenger cars.    

Adjustments

Because of the enhanced bias-ply technology, NA Racing Tires demand special care to perform at their best. The tires are not produced with steel belts, so they are less rigid and noticeably lighter than comparably sized radial tires. It is very important that all 4 tires are set with the same air pressure so that all of the tires have the same diameter to not compromise the car’s balance and to maximize the performance of the tires. NA Racing Tires are enhanced bias-ply tires and we highly recommend a tire break in warm up session to achieve the ultimate grip and lifespan from the tires. It is important to note that the tire operating temperature should not go over 100 degrees C or 212 degrees F as the compounds are designed to operate at levels lower than these limits. You can reduce the tire air pressure in small amounts to make sure the temperature does not exceed the upper limit.
