14 x 8 Cragar SS Size - Will it Fit?

Thanks for the input, what do you think about this thought. I'm now wondering if I will see a noticable differenece if I left the 215-70-14's in the front alone, and replaced the same in the rear with 245-60-14's on my 14x7 Cragars SS's, the spacing looks to be fine, but do you think an inch wider in the back will be noticable enough? The total tire diameter is only .3" diff between the front 70's and the rear 60's (smaller in the rear).
