Not necessarily. My old E30 318iS did 0-100 in 8 seconds flat with winter tyres, and 9 seconds flat with summer tyres. I guess cold air and lighter wheels with less intertia helps, but winter tyres have good traction when spinning. That enabled me to do a very aggressive start with lots of wheel spin, and keeping the RPM high all the way to 100. The summer tyres lost traction when spinning, and made the engine bog down when they were not spinning.
