Hi Mtimion;
Best way to fix your rims is to have them sand blasted clean and powder
coated. The powder coating will protect the rims and give a very good
sealing surface for the tires.
Tires can be purchased from a number of shops that sell Kumho tires. I
have gone on line with www.tirerack.com and web site does not show the tire
size, but they sell them. Also, you can call Hernandez Tire Co.
XXX-XXX-XXXX here in San Diego and they will ship them to you tomorrow.
