What he said. The only other factor would be the compound the tire is made from. Braking does need to be done with some finesse in inclement weather though. You can't just grab the brake hard, skidding is always possible. Traction is like a dollar bill, you only have so much to spend. You use it for braking, acceleration and turning. You simply overspent.
