Trying To Pick Out Tires

[theholycow]

The Kumhos also have a 100,000 mile warranty. The Pirellis are warrantied for 85,000 or 65,000 depending on speed rating.

As much of a fan of reducing rolling resistance as I am, I cannot ignore the quantifiable, known benefit of a longer wearing tire. While treadwear warranties don't assure you that the tire will actually wear for that long, they generally are a good indicator of relative tread life - more so than the UTQG, which is anything but U (every document about it cautions that each manufacturer sets their own standards).

Also, why didn't you run winter tires instead of all-season since you were switching them out anyway?

Personally, I'd go for the LRR, longer-wearing tires in a heartbeat, especially since they're priced lower too.

Edit: Check a tire size calculator before changing sizes as you propose. Not only will it be a little narrower (a strategy that I question), but if you get the same aspect ratio then diameter/circumference will be reduced also.
