Well, as I mentioned in the ice tire post, I split a lug on the outside rear tire, which ended my day. I cut the tire off and found that even though the lugs are only1/2" tall, the 1" long kutters I used barely poked through the carcass of the tire, and the bailer belt that I had inside the tire to help hold the studs was just flopping loose inside the tire since none of the studs were in enough to bite. I also seemed to pitch studs in only one set of lugs- the 2nd set in from the outer edge. The outermost lug started to split between the two outermost studs, but it only split about 1/16" - 1/8" deep from the surface and then was solid beyond.

So... I have a new tire with 1.250" long studs. The longer studs should bite into the belt with no problem (I think). I'm also thinking that I need to run lower pressure. I was running 12 psi- just enough that the tire had a slight crown, but since I ripped out studs only in one area- that was most likely the area doing all the work. I'm thinking a lower pressure would allow more contact and more evenly distrubute the load.

My finger is pointing at the missing stud area. The pic of the edge is hard to see, but the lug is splitting between the screws. Any suggestions?

We don't have ice racing in the UK , so This is guess work and what I would do.

Use slightly thicker belting and pop rivet the belting to the tyre first then install the longer studs.
It seems like the belting is turning inside the tyre and I think the tyre may be too softer compound.
The other thing was using the studs in a set of Kenda speedracer road tyres. These are a fairly strong carcass.
Like I said "Never tried" ice racing and outer my depth here but trying to help.

under inflation usually will cause studs to rip out. you may have to run a bit more psi with the weight and hp of the XX.

they make a flat locking "nut" that screws on to the stud where it pokes through the tire.

Great pictures of what slime looks like inside a tire.
