Wow - I've not had my current ride long enough to have a tire installed (and all my previous rides are too long ago to warrant comparison). But, I've seen a Craigslist ad for the past month offering a winter special for $20 per tire to mount and balance per tire if I bring in tire removed or $30 per tire if I bring the bike and they do everything. Didn't realize it was such a deal.
I have to say, I also haven't shopped tires AT ALL and was surprised to hear under $200 delivers for both tires. Granted, I've been buying BMW tires and 35" plus off road truck tires so I'm used to paying $300+ each just for the dang tire!
