1. If you have any other tire mod from me or someone elese, DELETE IT FIRST!
mine are BridgestoneDefault.scs & Bridgestone R187_FRT.scs.
BE SURE YOU DELETE IT FROM MOD DIR
2. Extract the downloaded files to your ETS 2 mod dir.
3. The file RealTireUpgradeDef.scs is meant to unlock all tires at LV1,
If you don't want to unlock them just delete it
