365 Tire Upgrade
Starting with Coach 1230, the standard equipment for front and tag-axle tires was upgraded from metric size 315 to 365.
The 365 tire offers the following improvements:
Increases the weight-capacity rating from 9,090 lbs. per tire for the 315 to 10,500 lbs. per tire for the 365.
Reduces the recommended inflation pressure from 130 psi for the 315 to 120 psi for the 365. This results in a smoother ride.
The Newell Service Department has developed upgrade packages for previously built coaches to replace the 315 tires on the steer axle with 365 tires. The scope and cost of this retrofit vary, depending on when the coach was built. That’s because some suspension designs require only new tires and wheels, while others also require new wheel hubs and fender modifications. Coaches with the Porsche-design front styling (one-piece windshield) also require some body modifications.
Anti-Sway Bar Upgrade
Beginning with coach 1292, we developed an anti-sway bar that attaches to the drive-axle suspension. The anti-sway bar reduces the coach’s tendency to lean because it allows the drive-axle suspensions on both sides of the coach to move equally and resists the tendency for one side to deflect more weight than the other. The reduction of lean at the rear of the coach results in a transfer of this stability to the front. If the rear of the coach is held flat by the suspension, the front suspension also stays flatter, side-to-side.
The Newell Service Department offers a retrofit of the anti-sway bar on coaches with ZF suspension. Customers who have had this retrofit installed say that it significantly improved the stability and handling of their coach.
