Hello,
Thanks everyone for the comments and advice; I appreciate it.
I took Ric's and bobbycorno's advice and ordered the Schwalbe Stevios from calhouncycle.com. They cost $46.97 apiece. I tried biketiresdirect.com, hoping to pay $35 apiece as bobbycorno suggested, but unfortunately my size was not in-stock. By the way, Hostelshoppe.com charges a full $54 for each tire, and their shipping charge is $4 more than calhouncycle.
Honestly, I love my Bacchetta Strada, but I wish they provided better stock tires than the Kenda Koncepts. I've experienced far too many punctures, and they seem to fail to hold the road well. I went down hard three weeks ago on wet pavement, going less than 7 mph, while turning. Of course, the wet road contributed to the fall, but for a moment even at the low speed it felt as if I was riding on ice due to the tires. By the way, I had to replace the entire derailleur as a result of the accident.
Finally, I will take Ric's recommendation and visit Power on Cycles in Plant City, Florida as soon as I can.
Thanks,
David in FL
