I have 1 year old tires, with 300 miles on them, Firestone Firehawks SS10 size 255/60/R15, on my show corvette, a 1978 Indy Pace Car. I'm noticing muddy brown rings on the tires. Dressings don't seem to darken the brown rings. Is there something I can do? I have now scuffed them, or rubbed them against curbs! Are the tires defective, or is there some release agent in the rubber coming out. My car really looks lousy with these brown rings. I have seen old BFG Radial T/A tires which are dark & pitch black, even the 20 year old GOODYEAR GT Radials I took off looked much much better.... HELP!
