245's in the front and 255's in the rear look good. I thought when you said 235/275, you were looking at 275/50's since they have approx the same profile as a 235/60, so it looks good from the side. You dont get that rake, but you get more meat on the rear. On my 70 and 71 Superbees, I have 245/60's in the front on a 7inch, and 295/50's on an 8inch in the rear, it looks really good! The 295/50 and 245/60 have the same side profile as each other. So, once again, from the side, the car sits pretty level, but has pretty fat tread in the rear. That is just the way I like it. If you want a bit more rake, then 255's or 275's 60s will give you that. My cuda has the 235/60 in the front and 275/50 in the rear, that is why I thought you were originally refering to it. I saw that you dropped from a 245 to a 235 in the front when you went with the 275 in the rear, so I just was figuring side profile. Anyway, its all personal preference, I just like a level car, and am partial to BFG, but many out there like the Cobras, and a bit of a rake. They all look GOOD!
