Black Ice Last Night
 
The weather reports said we would have "black ice" , and we did, in abundance. So last night, I got my mountain bike ready. I had to put the studded tires on. I had previously taken the studded tires off and replaced them with slicks , back in August, while my road bike was waiting for parts (striped headset) .
The studded tires , by the way, are IRC 26x2.125, they don't have a lot of studs, only every other knobby has a stud. IRC is the International Rubber Company.

I pumped the tires up to 44psi rear and 42 psi front, the rating says 40 - 50. I wouldn't want to make them too hard, or the studs won't be touching the road, they are offset , not on the centerline of the tire.

It was really scary last night, with lots and lots of black ice. We had about an inch or two of wet snow yesterday, while it was around 34 degrees F. The temps then plummeted after sunset.

Last winter I had been riding my bike with studded tires until we got a December melt...and then a quick refreeze. I thought the roads were clear enough, so I took my light road bike out. I was climbing out of the saddle when my tires found a small patch of black ice. On Christmas eve I was in the hospital getting a total hip replacement. I learned the hard way. Thank God I got a great surgeon who gave me a new titanium and ceramic hip, and was back on the bike within a few weeks after the accident.

I have to think back, it was a long time ago since I wiped on black ice, but I remember it hurt. Back when I was like 17, I made a set of studded tires, using half inch #6 , machine screws. The steel wore away after a season and a half. That's why studded tires are "Carbide" not sure if it's silicon carbide or tungsten carbide, but mild steel would wear out to quickly.
I don't know if studded tires are available in 20x1.90 sizes. I had to make my own, but they had their drawbacks.

" Hotbike" try lowering the pressure some, say to 30 -35 psi. I'm 230 lbs and run my nokian m&g 26x1.95 at those pressures most of the time.

I'll keep that in mind. I weigh 252, and I made the pressure a little higher, to account for slow leakage of the tubes. The tire says "INFLATE TO 40 - 50 PSI" so I didn't want to run them below 40

hotbike where are you riding ? I left from central Nassau to Queens yesterday at 5 am expecting to turn around and take the car in. I took a different route because it is more heavily traveled ,ie better salted, and better lit to see possible ice. Roads were completely white with salt. thank goodness as the studded tires I was supposed to get from brother were too dry rotted to use. new ones should arrive this weekend.

I only rode a few blocks, to the 7/11 store, on Glen Street in Glen Cove at around midnight. I rode very slowly, and there was a lot of black ice. I had one of those chicken Tacquito things that revolve on hot metal rollers under the glass counter, for a $1.49.
