The new Alliance 315 Port Star Plus is an advanced tire for port applications which is engineered with extra deep tread, which is the highest in the segment. The deep tread ensures longer life which results in superior performance. The robust nylon casing and high actual number of plies ensures high lateral stability and high load carrying capacity. The high ground contact area ensures pressure on ground is much lesser than max permissible pressure, thus resulting in more life and uniform wear. A strong bead bundle of the tire results in minimizing bead failure. The specially formulated tread compound and higher insulation between the plies aids in lesser heat generation, thus extending the life of the tire and provide excellent service on hard surfaces such as concrete.
