Anyone Running 50 Series Tires?

[1low69]

I finally picked out which wheels I am using for my first '69 SWB (yea, I was dumb enough to decide to restore two of these trucks at once!) Anyhow, I am running 20x8.5 front and 20x10 rear Boss 338's. I see most everyone running 25540's on the front and 29540's on the rear. This truck is dropped 5" in the front and 7" in the rear (static). I really want the tires to have about the same sidewall heights with about a 1" difference back to front (rear being taller obviously). My question is, has anyone used 25550's front and 29550's rear??????
