Compared to the Bridgestone Turanza ER30s that I came stock with the car, the BFGoodrich T/A KDs were a huge improvement.
I was very surprised at the improvement in steering response and tire grip while cornering, which is owed to the stiff “g-control”
sidewall inserts and the high silica content in the “BlackTech” tread compound. Where the ER30s would understeer,
the KDs would grab without a putter. The KDs are also very predictable at their limit, gradually oversteering without any
surprises while still maintaining a constant grip level. However, in wet surfaces the KDs become susceptible to sliding (video
link below), but with careful throttle and steering control the slides are manageable.
The only downfall with the KDs is that the tires are a bit noisier on certain speeds, probably due to the huge tread blocks
on the tire. Personally, I think the noise is very minimal and is easily drowned out by my music. Tire wear should be around
the same as the ER30s, just as long as tire rotation and pressure is regulated.
