I'm based in Christchurch. Got a few quotes from different places for 225/55R18 Preium tyres. Hyper Drive stands out from the group. I bought 2 x Yokohama G058 from them for $438.77 two years ago and they're still going well. I'm almost about to place the order. But if anyone knows a better option, please let me know.

I used Hyperdrive just last week to replace my tyres and found it really good.
Their RRP are grossly inflated but I liked the fact there were multiple outlets to get them fitted and the process was quick and easy.
