what does 91W or 96W mean?

I dont drive to wild at all but when I have noticed the slip light coming on the most was when I was getting onto the freeway on a downhill slooped on ramp and let off the gas a tad and then I feel/hear a change in the car. I read in the book about it and is it putting on the breaks or cutting engine power or both. I am really juut wondering if it is really that sensitive than when acclerating down an on ramp and I slighty lift that it freaks out and throws up the slip light. Also just want to make sure that there is nothing potentialy wrong with the car. Thanks for any help guys.

The rear tires are 245/45 and the sidewall height is 45 percent of 245 mm or 110.25.
