So, I got some new tiers before a big money race this weekend (same tires I have been running for many years, Hoosier drag radials 275/60/15's), set them at the normal pressure (18#'s)....first pass the car spun big time, had a 1.501 60' 6.65 @ 103mph. Temps were hot and humid, but all my friends were having zero traction issues, so the track was good. The car should have been in the low 1.4x's, even in the heat. I normally do short burnouts, so I thought maybe they need a little more burnout than normal to get them usable. Second time run, 1.499 6.64 @ 103.1, still spinning hard. Rd 1, went red (first competition red light in a few years :BangHead:) and the car did 1.494 60' 6.62 @ 103.6
Needless to say, I didn't buy back because I could not trust the car. So, my question is, has anyone else had a similar issue with new tires? If so, how did you remedy it? Me personally, I have never had new tires not stick before...so I'm kinda at a loss. The old tires that I took off the week prior (also Hoosier drag radials 275/60/15's) were still cutting 1.39 60' times when they started showing belts!
