I bought some Toyo Open Country 10 plys from him a few months ago, best tires ever on F350 SRW long bed with 20" stock rims.

Lets see some pix. I have a F350 and want to do 20in rims and maybe 305 or 315's what size did you do

best tires i have ever had! awesome in snow. just put on my summer set the other day. the olde goodyear at/s which suck in snow.

For what it's worth I studied every option possible for my '07 F250PS, ended up going with these. They are the E-rated 10 plys and are quiet and sticky because of soft compound, but I only got about 18,000 miles out of them. I only use the truck for towing, so they get worked, but I won't be buying them again. They are probably fine for lighter trucks and/or if they aren't towing heavy stuff all the time, but I wasn't impressed. Weren't all that great in the snow either, but were good on dry and wet pavement.

Also fixxer check your PMs when you get a chance I had a Ford-related question for you.
