Confused about tires

I have 225 70 14's all the way around. But it's very close up front. If you want all 4 the same size, I would recommend 235 60 14's or 245 60 14's on 7 x 14 Cragars. If you go 15 then maybe 235 60 15's. If you want to go wider than you need to lower the aspect ratio. for example; 255 55 14 or 275 45 15.
