Thanks Guys

OK, I concluded that i better carry extra one more front tire set including rim.
I just bought re manufactured front 18' rim via Ebay.

One thing not yet decided is tire size... either original 225/40/18 or 225/45/18...
One guy suggested that using 225/45/18 could be better than factory size 225/40/18, but no conclusion for the suggestion yet.

Think i have to decided the right tire size ..
Once again, thank you, Mrmiata, Onehundred80, Bjames, Turbomar, and specially Toolman. ^^
