Have had these for a week, put about 400 miles on them. At 46K my OEMs were down to 4/32 in front and then I found a nail in the RR. The Pirelli's are noticeably quieter and felt firm on dry pavement but felt terrible at 70mph over standing water (raining heavily and water standing in tire grooves). Felt like they were on the edge of hydroplaning and dangerous. The GOM also went down from about 42 to 38 but I was expecting that.

Got them at Discount Tire. Bought them based on good reviews but when I look at the tread design it doesn't look very aggressive. Not sure if I got the "Plus" version or what the difference is. Thinking about trying to return them.

Plus version has "plus" on the sidewall. What are your inflation temps?

I have not experienced what you are describing. Make sure your lug nuts are good too.

40 psi cold, lug nuts OK.

Tires say Cinturata Strada All Season. What does "Plus" get you?
The strada AS appearently is the same as the P7 plus but with deeper sipes and is supposed to be slightly better than the p7's on wet traction. I think they are exclusive to discount tire. They are a top rated tire and supposed to be superior in wet traction.

Having said that, hitting standing deeper puddles at 70mph will move your car around no matter what tire you have. The tire should have recovered quickly which I expect it did as you are still alive to post about it. A poor tire would continue to hydroplane for several feet. A newer tire will pull due to the ability of the water to slow you down very quickly on one or more tires when you hit the standing water but will continue to grip or grip within inches of hitting the water.

Last time I hydroplaned due to bad tires, I lost control and drifted across a full lane before the tires gripped again. That was as scary as it gets without getting into a wreck.

The plus has to do with low rolling resistance, light weight and high silica content. Yours are equivalent to the plus and are Applicable to the Volt.

I have those Perelli's on my Volt. I can spin them in sport mode on dry asphalt where as I could not with the goodyear Oem tires... not sure I'd buy another set.. they are quieter however...

What? Sounds like that's your problem

A LRR tire like the Bridgestone Ecopia's or the Michelin Energy Saver's will increase your mileage. I've driven on both and they're both very capable tires.

Based on reviews posted on this forum, I switched over to Michelin Primacy MXV4 recently. Very satisfied, quiet, sticks to the road,very slight range reduction. A pricie tire but I found a set slightly used for dimes on the dollar. Any tire you switch out to, measure the tread area width. The OEM GYs are slightly less than 7" but other tires in the same size can have up to an 8 1/4 tread width. This affects range and fuel mileage greatly. Stick to the narrow tread width.

Standing water at 70 is an extreme test. I wouldn't necessarily write off the tire for that. But you are the one who has driven on them and you know if they feel safe or not. I got the Continental TrueContacts, and I feel like they are excellent in the rain. Well reviewed as well.

Just to be clear I was far from the fastest car on the road, just getting around the semi's. Unfortunately the studded tires widely used around here result in water collecting tire grooves in any pavement not recently laid.
