Today I went with a Friend in his Avalanche Z71 up to the end of Holy Jim Canyon in moderate rain. Nothing required 4x4, but had not been there in decades and forgot how pretty.
Rain started coming down pretty hard on the way out!
Beers at Cooks Corner!
I have had other brands of tires discolored like this. Took a stiff brush and soapy water and scrubbed them real good.
Then put your fave tire dressing (like McGuires). Like new!
