OK, I give up. I can't take it any more. I'm going to bike in the winter. But I want to do it with my 84 Bridgestone, because it's my least valuable bike and I don't want to buy a mountain bike for 2 months of riding. I'll be going down south to KS in March, where my Atlantis is waiting for me.

So.... where can I get winter 27" tires?

Assuming you can fit a 1-3/8 tire, you could try the Kenda KrossCyklo 27 inch tire. That's what I'm trying next. Or maybe the Schwalbe HS159 Puncture Protection 27 x 1 1/4. I like to have some tread in the winter.
I generally just try to find something with some kind of blocks to it.

Huh....I had a similar question in mind and who do I find asking it but a fellow 50+er!

Thread hijack: I know there are car snow tires made with abrasive materials mixed into the rubber (such as ground walnut shells). Anything similar for bikes as an alternative to studs? Perhaps like Solveg, I want to ride on the occasional milder winter day when the roads will be mainly dry except for the occasional slushy patch. And my rims are 27" on my SS/FG conversion.

Two months? Where can I find these two month winters?

Not in MN! I'm bailing!

I believe 27" studded tires are hard to find. Most sell 26", 20" and 700's.
If you can't find 27's...maybe a used cheap used Mtn. bike outfitted with
26's just to see how you like it?

If you enjoy winter riding and want good tires, try

I bought Schwalbes from him with carbide studs and like
them a lot. A month and a half of commuting and no noticable
wear on the tires or studs yet.

Happy Trails

I just switched tires on my Miyata 710 winter bike to Tioga Bloodhounds cross tires and I love them so far. There's a fresh layer of granular snow out on the roads this morning, so we'll see how they deal with this type of snow, but in the powder the other morning, they were very comfortable (and comforting) to have below me. (I'm in Salt Lake City, btw, for reference). I did have to pull the fenders off, too much tire for the space with them on. I'll take wet over a crash, though.

I think the Continental Top Contact Winters are like that but I haven't been able to find them even in the 26" size. I'm pretty sure they're not made in 27".

Just as an update, bcoppola and I both got mountain bikes and gave up on the idea of riding the 27" tires...

Same here.
