When I tried to register, I discovered I was here about 8 years ago when I bought my 54 1 1/2 Ton. Now that's sold, (plates were too expensive, overkill for current needs), but yesterday I bought a 51 !/2 Ton. I don't have it home yet, and I'm trying to gather info. Right now the truck has 15" passenger radials on it. I think 16's were OEM. This will be a user truck, not a trailer queen, but I want to keep it as original as I can. Any ideas on what tire size would be better. I plan to run 6 ply rubber, looking for ideas. I'll be back with more questions as this progresses. Also, I'd like to find a picture of the original rear view (tail light, license bracket location) Thanks for any input. John
