I have 8-17.5 bias ply tires on my C-30 dually flatbed and the front tires are worn and the rear have decent tread but are very old. I have been collecting these obsolete tires trying to get together a decent set and I have found 6 radials that are decent but I also have 2 brand new bias ply. Any thoughts from you all about running the bias ply on front and radial on the rear? The truck is mainly a weekend around town driver, thanks.
