Hi, Dennis.
Q45tech wrote:Why do you think the Pilot H4 is dangerous in wet weather? We have been using then exclusively for the past 3 years on Q/ big Lexus as our recommended tire. Must have at least 100 customers who use them. We don't sell them we send then to Sams Club or their own reailer.
I have used at least 2 sets in the last 3 years.Like any tire you must replace when the tread is half worn to achieve optimum wet weather performance.
Of course not the wet weather tire the SZ50 was [the SZ50EP replacement is harder but not as hard as the Michelin].
Just because Michelin labels them as a 400 tread wear, on the Q they act more like a 300 in 235/60/15 size.
Most people who can put up with directional tires would be best served with the AVS DB S2 if cost is a concern.
I have ordered 255/50/16 Pilot H4 for my new/used 16x 7.5" Z wheels for the Q.
On my 1991 Q, I had the Michelin XGT V (OEM), one set of OEM XGT V replacements, and then switched to Pilot XGT V as the last set before trading the car in. Tread lasted well in all cases.
On my 1995 Q, I had Pilot XGT V originally (last owner had them), switched to Bridgestone RE940 and then had to get the Pilot XGT V's again for one more try because of a serious problem with the Bridgestone (inner sidewall gave way unexpectedly - fortunately, I was not at high speed!) and the local tire dealer only had the Pilot in the right size. My current set is the Firestone SZ50EP.
On all the Michelin's - whether original OEM version or the Pilot replacement - I had serious concerns about their wet weather braking and handling. Even when tread was relatively okay - like over 5 to 6/32's. I skidded and spun the car (both Q's) on more than a few occasions in light to moderate rain. Starting out from lights was always an exercise in gentle modulation of the accelerator to prevent tires from slipping and the car from sliding around - turning from a light was another thing entirely!
After tread dropped below 5/32, my driving on the highway (in rain of course) would beome what I will call a "white-knuckle" experience. I would maintain an long extra distance between cars and drive slowly - a classic "old guy behind the wheel" syndrome. Way too tense a driving condition for me!
Hence my complete wet-weather distrust of the Pilot XGT V!

As far as I am concerned, I have driven enough miles on the XGT V and Pilot XGT V to be certain about my concerns!
But, I have to admit I do assume the same "worst wet behavior" of the H rated tire too, which may be unfair since I have not used them.
Regardless, compared to these XGT V and Pilot XGT V experiences, the Bridgestone RE940 was a major improvement and the Firestone SZ50EP is just a totally awesome change!
