On my 2000 XJ8, I installed BF Goodrich Traction T/A H's, mainly because
they came with a mileage warranty. For our driving, the stock Pirelli
tires were a terrible choice and were replaced at 12,000 miles. I have
not noticed a difference in road noise. Here in Phoenix, many of the
urban freeways are being paved with rubberized asphalt and that reduces
road noise a lot.
I tend to keep the tire pressure at 30 pounds rather than the
recommended 28/26 and that does stiffen the ride a bit. My reasoning is
the Ford engineers have already demonstrated incompetence when it comes
to tire and air pressure choices and it gets hot here.
Your mileage may vary.

Thanks. I may try them. The Pirelli's have a terrible reputation, but are
supposed to be fairly quiet for the first 20K - 30K miles.

I noticed the quietness of your freeways when I was in Scottsdale last
summer. Here in So Calif, the opposite is true.

It may be a bit stiffer, but I'll bet it's like driving on silk.
Thanks again for the info.

On examination, I found that the BF Goodrich A/H is the highest rated tire
available, and at prices the seem ridiculously low ($80ish). Tomorrow my
baby gets new shoes in the form of T/A V's. I chose the V rated instead of
the H because they profile more closely to the recommended Z, which is
recommended not for the speed, but for the breaking characteristics.

I understand your reasoning to be sure, but why go higher in pressure for
higher ambient temperature?

I am not an engineer, but I think low tire pressure causes the tires to
flex more as they roll and flexing causes rolling resistance and
therefore more heat buildup in the tires.
I recall reading somewhere the initial tire pressure recommended by Ford
for the Explorer was 25 pounds, and after the rollover lawsuits became a
burden, the recommended pressure was raised a few pounds. By contrast,
the recommended tire pressure for my 1998 Jeep Grand Cherokee is 35
pounds, and the Jeep has a softer ride than the 1998 Explorer. I don't
have much evidence, but to me it seems that Ford has a tendency to
tradeoff over-stressing tires for some other advantage, presumably a
softer ride.

Buy a set of 20" Detroit alloys and fit the following:
Pirelli PZERO ASIMMETRICO - 285/30 ZR20TL 99Y(J) - REAR
Pirelli PZERO DIREZIONALE - 255/35 ZR20TL 97Y(J) - FRONT
Job Done....
Low noise, good handling, empty pockets....
