Tires Pirelli or GT Radial

I'm on the Cinturatos and although they are a marginal tire the car is rock solid on the freeway.

Went with the P4 four seasons plus. the tires are night and day better than what was on there. Ride is smoother, much quieter, better wet traction.

I put Cinturato P7 All Season Plus's on my mother's Tiguan and overall these seem very good. They are noticeably quieter than my Michelins on coarse roads. Performance is good, but they seem to be wearing a little quicker than anticipated

Currently running GTRadial Chamiro UHP1 tires and am about to install my 2nd set. They are CHEAP and almost as good at the Direzza Star Specs on my Porsche. I was shocked I got 20k miles out of them, they grip really well and don't get greasy easily at the track.

Yup, OEM size on the Bristols. I was honestly just going to get the conti's again as the mileage I got out them was enough reason for me to buy. Then I found the P7s on sale and paid less for them than I would have the conti's. I was also curious to see if the low rolling resistance made any difference. I think it's a slight improvement, but the sound (I mean lack of) you can't compare.

I've been driving on the Pirelli P7 Cinturato's for 18k miles and have nothing but good things to say. There has been little to near visible wear to date and they grip, ride and handle so much better than the OEM Conti Pro contacts that I had...and I really liked them, got 71k miles out of em! The greatest difference so far seems to be the amount of road noise. The P7s are so much quieter it's not funny!

I've had P7's on my about to depart 2013 SEL for about 8 months. Really happy with them dry and wet. Amazing improvement over the crappy OEM Hankooks.

I haven't had any issues with vibration, but have noticed more road noise on my Pirellis after 20 K. Probably won't get another set.

I have Pirelli P4's... I love the tread warranty - expecting that I'll get 9,000 miles out of them. But I find that I'm losing traction more often than I'd like when I accelerate, and make turns.

Similar story: a lovely pothole seemingly gave me a flat (felt really jarring) on one of my Pirelli Sottozero 3s. Was flat within 10 minutes...Turns out the pothole actually cracked the rim (which caused the flat) and then the short time I drove on it mostly flat, had ruined the sidewall on the tire as well.
