Indeed, the Triple Tred might be the better choice if you don't have winter tires as it fares better in snow than the Comfortred, that I would have chosen because it is even quieter and more comfortable.
The Avid TRZ doesn't yet have a lot of miles reported but sits on the second spot in the standard touring tires category;

As I said, a great set of tires so far except maybe 2 things;
1- Noise comfort is good but not great. Some have reported that it improves after some mileage has been put on the tires and I have less than 1K mile on them. And a Corolla is by no means insulated like a Lexus, even a Camry.
2- Steering is a bit loose on center at highway speed, but again, the Corolla has a slow steering ratio that no tires can quicken I guess, no matter how good they are.
I mentionned inflation pressures because a fair number of members on the Corolla forums inflate their tires at 35 or more PSI and I just don't see the need to. At 28 PSI my rear tires still look perfectly round at the contact patch. I'm afraid they would wear in the middle with any more PSI.
The problem with the el-cheapo OEM tires is that the do fairly well and are fairly silent on good pavement, when new, during the test drive (who test drives cars in bad weather?). It's once you drive on them in all possible conditions and that they start to deteriorate rapidly afterwards that you realise how bad these OEM tires are and how much a better set of quality tires will improve the overall behavior of your car.
For obvious reasons, manufacturers like Honda, Toyota or GM are unwilling to say to their customers who buy Accords, Civics, Corollas, Camry's, Impala's, etc. "Well, for an additionnal $200., we replace those rim protectors with high quality tires of your choice between a choice of, say, 5 different brands or categories and make your car feel like you spent 2K more for it."
This is my thoughts on how an el-cheapo 05 CE Corolla like mine now probably feels more expensive and secure on the road than an LE or S with stock tires.
BTW, Colt, I have a set of US Corolla S (canadian models come standard with alloys) 5 spokes hub caps that I bought on e-Bay. Brand new in the box. I also found an LE center console armrest for cheap. Now, I need to get rid of my Integrity's with only 3000 km on them to pay for those goodies.
