Default Load Rating: How low is too low?

I'm building a set of tires for ice time trials this winter.

I'm going to be drilling the tread and adding bolts to the tires.

I have a chance to pick up a set of 205/45/16 tires real cheap.

The problem is they only have a load rating of 83W, or 1074 lbs.

According to Luke's Tire Tech thread, the minimum recommended rating for a WRX is 1135 lbs.

I wouldn't consider these for normal driving, but since I'm going to be using them only for short periods, and they're going to have bolts sticking out of them anyways...does the load rating really matter?

Am I risking blowing out a tire and/or damaging my rims?

If not at risk, are the tires just going to have too much sidewall flex, leading to decreased performance all around?

Absolutly, without any possible doubt.

You're basically a hair below the minumum. Ice racing (if its smooth) won't give you the same weight transfer as a dry course, I'm not sure how bumpy it is either. Any chance of getting airborn? You'd be right on the edge. There are factors of safety built into those numbers...

It's bumpier than asphalt. The course is usually set up with a couple long straights where I was in 3rd gear on snow tires.

Generally nothing airborne, but there is always the chance that I will take a foot high snowbank at 40 mph.

For reference, last year a guy was running studded rally tires on WRX spare rims, and he pancaked the rims his first day out.

The more I think about and describe what the race is like...the more I'm realizing I need to spend the extra $$ for higher load rated tires.
