Help fast can't decide between 225/45/15 OR 215/50/15 stock z28 rims I have 2 inch spacers

 

Those are tiny tires for a third gen. I would expect 60 series for 225/xx/15.

 

Suitable sizes are 215-65-15, 225-60-15, and 235-60-15.

225-45-15 is going to be 4" shorter than the factory tires!

 

Thanks everybody just went with 275 60s

 

That's a big swing from the tires you were originally looking at!

225/45/15 8.8" wide x 22" tall
215/50/15 8.5 x 23.5
225/60/15 8.8 x 25.6 <- my/Paul's recommendation
275/60/15 10.8 x 28 <- 2" wider and 4.5 to 6" taller!

275/60 would be typical for a larger rear tire going for a raked or big-and-little look. But, I think it too big for the front, and will look like a 4x4.

 

Haha true the fronts are 235 forgot to mention that oops
