Which winter tires provide the best grip for Infiniti Q50 AWD?

Honestly, I totally get where you're coming from. I've been driving my Q50 for five winters now and, unfortunately, the stock run-flats are just garbage in the cold. They turn into hockey pucks! I had some issues with the popular choices feeling too soft, and like you mentioned, that 'marshmallow' feel really ruins the sporty vibe of the Infiniti.

For your situation, I would suggest looking at the Pirelli Winter Sottozero 3 245/40R19. While people already mentioned the Blizzaks and X-Ice, those are 'Studless Ice & Snow' tires which are great for pure grip but usually feel pretty squishy on dry pavement. The Sottozeros are 'Performance Winter' tires. They’re designed specifically for high-performance sedans like ours to maintain handling while still biting into the slush.

Here’s why I recommend going this route:
* **Dry Road Performance:** Since you have a 30-mile commute, these won't drive you crazy with road noise or that floaty feeling at highway speeds.
* **Emergency Braking:** They have a stiffer carcass, so the car doesn't dive as hard when you slam the brakes on black ice.
* **Sizing:** I actually stuck with the 19s because I hated the look of downsized wheels, but if you want to save money, a set of Vredestein Wintrac Pro 245/45R18 on some cheap alloys is a solid alternative.

That said, if your area gets *really* deep unplowed snow, the Sottozeros might struggle compared to a dedicated ice tire. But for a mix of highway and icy suburbs? They're hard to beat. Hope this helps!

Hi there! Honestly, I totally get the nerves. AWD is great for getting off the line, but it's useless for stopping 4,000 lbs of Infiniti on ice. To understand why, you have to realize that all-seasons harden like plastic once it drops below 45°F. Dedicated winters use a softer silica compound to stay pliable, which is literally the only thing that'll save you during emergency braking.

Warning: Avoid the Bridgestone Blizzak WS90 if you're sensitive to noise. I had them on my Q50 and, unfortunately, the highway hum was unbearable on my commute. They felt way too squishy, like driving on marshmallows, which totally killed the car's sporty feel.

Here's what I recommend:
1. Get the Michelin X-Ice Snow 245/40R19. They're much quieter on dry pavement and hold the Q50's rear-biased handling way better than the Blizzaks.
2. Definitely downsize to an 18-inch wheel like the Enkei Performance Tuning Raijin 18x8.5. The extra sidewall helps with potholes and makes the ride less jarring.

Hope this helps! Let me know if you have more questions.

Quick reply while I have a sec! In my experience, winter tires are less about the tread and more about the rubber compound staying soft when it's freezing. If you want to save some cash without sacrificing that sporty Infiniti feel, honestly, you should definitely downsize to 18s. It makes the tires way more affordable and gives you a better ride over winter potholes.

Here are a few tips for your Q50:

* Look into the Continental VikingContact 7 225/50R18. They're usually priced better than the big names but handle dry pavement surprisingly well without the road noise.
* Go with a 225-width tire instead of 245. Narrower tires cut through slush way better, and it's cheaper too!

I mean, well, actually, the 18-inch setup also protects your nice OEM 19s from all that nasty road salt. Anyway, it's a solid way to get better braking performance on a budget. Hope this helps!

^ This. Also, I’ve been driving these for years and honestly, the biggest mistake I made was trying to keep the 19-inch setup. Unfortunately, I had issues with a set of performance-style winters—specifically the Dunlop SP Winter Sport 3D—where they just didn't have the bite I needed on the nasty slushy stuff. I remember one commute where I nearly slid right into a ditch because the compound was just too stiff for the deep cold. It was a huge disappointment and really shook my confidence. Tbh, people get way too overconfident with the AWD system. It helps you go, but it does absolutely nothing to help you stop 4,000 lbs of steel on black ice. I’ve learned the hard way that if you prioritize that sporty feel, you’re almost always sacrificing the actual safety grip. I eventually switched to 18s and the difference in reliability and comfort was night and day. You lose a bit of that sharp turn-in, but id much rather have a car that actually stops when I hit the brakes than one that feels sporty while I'm sliding toward a bumper. Just be careful with those low profiles tho... they're magnets for pothole damage once the snow starts melting.
