This may not belong in here, but could someone please help me.
what is the biggest combination of 15 inch tires that will fit on my 1990 iroc z?

I currently have 255/60R/15's cooper cobras on the back and 235/60R/15's on the front, but would like to go a little bigger as i am tractionally challenged. say would 295/50R/15,s fit?

and how about 255 or 265/50R/15 on the front?

would the 295's help with traction? i can get a good deal on a set of dunlop gt qualifiers.

put a 4th gen rear end in

go get yourself some 17x11s with 7.5" BS

315s

 

sounds as if your traction problem is cheap tires. white letters on a tire do not make them good for traction. a 265/50 will fit, but a smaller tire with a softer compound would take care of the job just fine.
