Ok here it goes, I have 17" Gianelle 5 twin rims with nitto 450 extreme tires on them and i've had them for the last 3 years. And I love those tires, they gripped REALLY GOOD, and they looked sweet. BUT they don't make them anymore. I know there are better ones out there now but my front ones are brand new. And i only need the back 2 replaced. So it will be kinda stupid to replace all 4, but I don't like to miss match tires, because every tire performs differently. So if anyone went from the nitto 450 tires to a different tire and feel that they performed the same can you tell me what brand you went with. I've read that the Falken Ziex ZE-512 are a #1 seller, but how do they perform? Can anyone share some info on what tires to get?
