I currently have Firestone Precision Sports on my 2011 G37x. They were on the car when I bought it. I find them to be VERY noisy.

On my prior car, a 2005 Volvo S80, I had Bridgestone Turanza/Serenty A/S. They drove nicely and were not noisy. And, they lasted 50k miles (which is not my #1 priority, just a bonus).

Is it a bad assumption to think that they will perform similarly on the G37x in terms of handling and noise? The S80 is not AWD.

What are other recommendations for A/S tires for my car?

 

I just purchased the Continental Extreme Contact DWS. I am very satisfied with the purchased.

 

Really happy w/ my Toyo Proxes 4 Plus, mine are Y speed rated too.

 

Big fan of the Michelin Primacy MXM4.. very quiet, stick great in all conditions...great reviews on Tire Rack.. Also the new Michelin Piolt Sport A/S 3 looks to be a winner, but it won't be as quiet as the Primacy.. The Bridgestones are also a good tire.. but I think the Michelin is a bit better..

 

I have been looking at those as well. However I have seen several reviews that you loose the "sport sedan" feel when you switch to those since they are touring tires. Did you notice anything like this?

 

The Continental DWS were a popular option when I bought them in Feb. They have decent traction but have soft side walls. That equates to a little more body roll on turns.

If sporty handling is important to you, i suggest you consider the Toyo Proxes 4 Plus.

 

I didn't feel like I lost any sport sedan feeling but it is a fairly compliant tire, much the way the Bridgestone Turnaza Serenity is.. If this is a concern then go for the new Pilot Sport A/S 3.. as a side benifit the A/S 3 are a bit less expensive..

 

I appreciate all the responses.

What is the main difference between an grand touring all season and an ultra high-performance all-season?

My 2005 Volvo S80 was not sporty but the G37x is so I guess I should try to get the most out of that without sacrificing safety.

 

i think it really depends how often you plan on driving in the snow. My Toyos probably aren't the best in snow but for dry & wet traction they do very well. I've only had them in a 4" snow and they did alright, but there are probably better snow tires (without actually going to true snow tires).

 

I live in the Philadelphia area so we normally don't get a lot of snow. If we do I will probably keep the G37x in the garage and go out in my wife's SUV.

When I think of non-dry conditions I am much more concerned with wet roads from rain since those are more likely the conditions I will be driving in.

 

The main reason you want all-seasons is for snow &/or freezing conditions, if you only drive your G above freezing where there's no snow you may be better off going w/ a good summer tire. Most have great wet traction and obviously the dry grip will be better.

 

I too have the DWS and noticed the sidewalls are considerably softer even when compared to the OE RSAs. Great tire in the wet and light snow, but I wish the sidewalls were a bit harder and appeared to be less rounded.

 

Bridgestone Potenza RE 970 AS. I had the earlier version of this tire on my TL and loved it. Put them on my xS recently - They handle better than the OEM tires and are not too noisy (as new). I can't say anything about snow traction yet.

A tire I decided to avoid was the Hankook Ventus V4 ES all-seasons that some Infiniti dealers are putting on used 6MT cars. They give excellent try performance (for an all season tire) but get extremely noisy as the tread wears.

 

Snow traction on the 970as pole positions are pretty good, i have the v4's on another car and compared to the bridgestones they aren't as good i was all over the place in the snow. I recommend the RE970AS. The wet traction is good also the only time i slide is when i turn off VDC for a little fun

 

Here's my 2 cents... If driving in deep snow is not a concern, I would shy away from the DWS tires. They are incredible in snow, but there is definitely a trade off for handling. I agree with ZenZiglar & Adam West that the sidewalls are soft. I do not have them on my g, but did have them on my m. The car lost a lot of it's cornering ability and there was a lot of turn-in with the DWS tires. I also had one tire get a bump in the sidewall due to the soft sidewall. I always ran at least 38 - 40 psi in the DWS just to regain some handling...
