noises, tire size, and manual trans/diff fluid

[Quattro8880@aol.com]

My summer wheels and tires are 15" speedlines with 205 60's. When it started 
to get cold here in NY, in the mornings, the front wheels would make a sound 
as if the diff were locked, when turning out of my parking space. It also 
shifted stiffly until it warmed up. I changed the trans/diff fluid to Mobil 
one, and it actually made it worse. I figured that I would just have to live 
with it.

I changed back to my winter wheels, 14" with 195 60's. Problem Solved.

I know the 205 60 15's were too big, and will be changing to a 205 or 215 50 
n the spring. 

Can anyone offer an explanation to this ?
