Yes, some tires don't have the UTQG rating printed out. Tires made in Indonesia for local Indonesia market often are missing this. Long time back my old Dunlop Dignos and Bridgestone Potenza also did not have them.
As the title of this thread, any recommend on the shop that can refurbish and change the air-cond for RX7? I've just bought my 1st RX7 FD3S recently, and i'm trying to refurbish the interior and change the air-cond...
