The Hankook Z221 C5 is a DOT-approved semi-slick extreme performance summer tyre built for competitive motorsport use — track days, time attack, hill climbs, and tarmac rallies. It's sold in a single 235/40R18 size in the premium price tier. This is a purpose-built competition tyre, not an everyday road tyre, so consider it only if you're chasing lap times rather than daily comfort or longevity.

    Had such a great experience with Discount Tyres Grey Lynn last week! The team were incredibly friendly, welcoming, and efficient from the moment I arrived. They had a new tyre sorted for me the same day, which made a stressful situation so much easier. What really stood out was the extra care, they even put my brand new spare back in the boot, ready to go for next time. It’s those small touches that make a big difference. Highly recommend if you’re after great service and genuinely helpful people!

    Three years ago, I chose Discount Tires in Grey Lynn for my tire needs. Just recently, I visited them again for wheel alignment and balancing. As always, they did an outstanding job. Their attention to detail and expertise in ensuring my car’s wheels were perfectly aligned and balanced was impressive. It’s clear that their commitment to quality and customer service is consistent over the years. Highly recommend them for top-notch service and reliable products!

    What Auckland City Toyota- Grey Lynn couldn’t fix in 2 weeks, Discount Tyres Grey Lynn fixed in 90 minutes. After months of going back and forth with Toyota - including a recent process where they had my new RAV4 Adventure for two weeks yet still insisted there was nothing wrong - we went to Discount Tyres Grey Lynn for an independent review, who solved the issue in a single visit. They took the car straight in, went on a proper test drive, and immediately confirmed what we had been feeling all along: the car pulled left more than normal, and you had to hold the steering wheel to the right to keep it straight. Even a Toyota-arranged “independent” test drive at Albany Toyota failed to find the problem because they didn’t test it under the right conditions. Discount Tyres listened with care and attention, investigated thoroughly, and fixed the problem with ease. A simple tyre rotation, rebalance and three test drives later, the guys confirmed the issue was sorted. The car now drives like brand new. No excuses, no delays - just honest, professional service and a vehicle that finally feels safe and right to drive. Nick and Wayne were friendly, efficient, and genuinely cared about diagnosing and solving the problem. I highly recommend Discount Tyres Grey Lynn for their professionalism, goodwill, and integrity.

    Wayne gave me the best service. Said he could complete my job in 1.5 hrs, and he did! Great being able to just pop in without an appointment and receive such efficient service. Thanks for helping me get to my lunch date on time !
