As the stock H-rated tires are "OK," but not great . . .

What are some good match performance tires for "New xBs?"
Which work well for the particular characteristics of an xB's handling parameters?

(As many of us are coming to the xB from a wide range of vehicles and few of them have enough miles to actually burn up a set of tires, there should be a bunch of people on here and "guests" who would benefit from this info.)

Oh, I know.
"H" are generally designed more for highway and interstate use by sedans. As such, the rubber is compromised more for lifespan than stickiness.
The reason Z and the like tend to be "better" for performance is that they are usually designed to be grippier.

Oh, all tires are a compromise between several factors, which are commonly shorthanded as life/miles vs. handling performance. True racing tires are high on stickiness/grip, but low on life. Heck, most get completely worn out in a few hundred miles and often less than 100 miles on many upper racing series.
Street tires give up some grip for a longer life span, with each as a different compromise and falling under one of the "class" categories. High to extreme performance tires have less lifespan, but more grip than most street tires. "Passenger" tires are usually designed more for lifespan than ultimate grip.
High grippy tires won't last 80,000 miles, with most lasting 15,000-25,000 miles. It is all a compromise based on what is important to the user and vehicle. Most "High Performance" to "Extreme Performance" tires have a higher speed rating than H, even if the xB is aerodynamically challenged in getting anywhere close to that listed speed.

I tend to like them more grippy than long lasting. So, I get higher grip tires, at the cost of lifespan.

For my Miata, I have generally been getting Toyo T1S (now the T1R model) and BF Goodrich G-Force Sport tires. Both are good grip and work very well with a Miata's weight and suspension. I run 195 or 205/50/15s, which are smaller overall diameter than would fit on an xB (though the bolt pattern is the same as an xB1).
Are these tires also great for 08-09 xBs?

What other good options are out there for xB2s?
Tirerack returns (for 16" size) 95 tires rated V, Z, W, and Y. Any known guidance for xB2s or is this vehicle to new . . .

OK, OK, I KNOW that "H Rated" is a SPEED RATING!
-My comment was based on MOST h-rated tires being designed with the compound compromise "weighted" more to life than grip. Of course, a particular h-rated tire may not fit into that.
Speed ratings:
Q- Up to 100mph
R- Up to 106mph
S- Up to 112mph
T- Up to 118mph
U- Up to 124mph
H- Up to 130mph
V- Up to 149mph
W- Up to 168mph
Y- Up to 186mph
Z- 149mph and over

-Honestly, I'm not sure IF a normal aspirated 08-09 xB could even HIT 130, on a 15 degree downhill slope, with a massive tailwind!

In GENERAL, H-rated tires are intended for street use by cars like a Ford Taurus, Crown Vic, or the like. So, they have enough grip for normal driving, but they are a bit "harder" to allow for a longer life. CERTAIN h-rated tires are high performance and designed for spirited driving. I KNOW that!

My comment was more aimed at the Bridgestones that came on my XB. I would (eventually) like something more grippy and was interested in what tires OTHERS think work well on xB2S!
My personal experience is with a lighter car that uses a very different suspension design. So, my experience may or may not be relevant for the xB2's performance tires. So, I ask.

What tires do ya'll like the handling performance of with your xB?
Which have been "bad" and why?
