Installed a set of Billboards in May:
Comments/Experience:
1.
Fit: very well, 10" tread fits better than the 11" tread of the Goodyear GTII's replaced.
2.
Grip: excellent (Trade off does pick up gravel if there is any)
3.
Cornering: excellent
4.
Wet Roads: did not experience but these are race tires fro rain.
5.
Roll: Good on smooth roads. Bias ply does tend to follow irregularities on secondary roads. More steering input needed.
6.
Weight: significantly lighter weight, at least 15 lbs per corner.
7.
Track day: excellent, can't ask for better. (OKAY: slicks might be better; tried them, too.)
8.
Safety: on the track, no problem. On the street where I live, there are always road projects and other things like worn out roads and I was uncomfortable with possible damage, so...got a set of Mickey Thompson Sportsman S/T's for the street.
9.
Look: Can't be beat; "right" look on our roadsters.
Summary: Satisfactory street tire w some compromises as stated. Excellent track tire.
