Default Daily driver tire size for a 2011 WRX hatch?

Good evening gents,

I'm looking to replace the SP01's on my 2011 hatch with some all season tires. At first I was considering the 245/45/17's, and my search on this forum yielded posts telling me that 245/40/17's will yield better performance. I've also seen posts saying that 225/45/17's will have better performance in the snow. So, to all you tire experts on here, exactly what should I be looking for in terms of a daily driver tire size? I don't do auto cross, live in the NY area, make yearly trips to Maine about a week long during the winter, and will likely never track the car. I suppose comfort, less stress on my drivetrain, durability, and safety in snow/rain are on my list of characteristics I'm interested in. I'm not interested in rolling my fenders (is that the term?) or lowering my car either.

Thanks, and please excuse that wall of text!

235/45/17...same as factory.

In all seriousness, you are stating that you might do one way for performance then stating that you migh tgo another way for winter traction. If you go either way, there will be a detrimental impact on the other.

As you are going to an A/S tire (which is a compromise from the beginning, versus dedicated winter & summer tires). This is a necessary compromise for MANY owners for many reasons (storage, cost, rapidly-changing weather). If your specifics have you favoring non-winter performance over winter grip, then go with the 245/40. If winter grip means more than the best traction that you can get from an A/S tire, then go with the 225/45.

For me, my "winter" setup is a 235/45/17 Continental ExtremeContact DWS, because I have changing weather conditions and the possibility of light snow in 6 months of the year, BUT I did not want to be doing 100 miles per day on winter tires for 6 months out of the year so I went with an A/S tire with good snow ratings.

I actually bought them to be a 12-month tire (with the acceptance of the compromises), but then I scraped up the cash to get a dedicated summer set to run half of the year.

If you are going to get separate snow tires get 235/45/17 or 245/40/17 for the daily drive as a summer tire and get a set of 215/55/16 for snow tires on steel or heavier duty aluminum wheels.

If you are using the same tire year round, 235/45/17 in a good all season.

If you want a better performing tire get a shorter size as well, it really helps the gearing.

phenryiv1:

Sorry about my mix up of terminology, I assumed that traction = performance, and now know that is not the case. Thank you for the detailed response, and yes, I am looking to have a set tires that are good for all 12 months. Our snow season is about 3 months long at most, and only a few days of them will actually have snow on the road. From that information, would you think that all seasons in 245 would be better, since there is a huge bias for driving in regular road conditions? From what CopperTopNWOR and yourself have said, it sounds like I should simply stick to the factory size for the best compromise.

sc00by4life: If I go with a shorter size tire, wouldn't that make them "lower profile" than factory? NYC roads aren't the greatest, and I worry about getting bends in my wheels from hitting one with the current height already. Won't it affect my speedo readings as well?

Thank you for your time gents!

Yes it will impact the speedometer, and yes it would make it more likely for you to end up with a cracked/bent wheel. Stick with the 235/45 to be safe. You could go to 245/45 but it would hurt performance in terms of acceleration and handling slightly.

The stock tire size is pretty good in reality.
