Mine's a 96 B3000 4x2 with 147,xxx km. Same stock tire (225/70R14). For winters, there is a Dean Wintercat....Apa.ca has poor reviews on these tires. For other seasons, there are a few more around.
For winters, I have a set of four studded Arctic Claws TXI (205/75R14). Bought them for $522 after mounting, balancing, installation and studding ($80 per tire). Previous winters were 215/70R14. Have the Claws at 38 psi since they have a slightly lower load rating (95 vs. stock 98). Got the Claws since they were among the cheapest, studdable, non-directional winter tire available. They are an entry level winter tire IMO....still got stuck a few times last winter (needed a push from neighbours or put on chains).
For other season tires, I have a set of four BFG All Terrain T/A KO (27x8.5R14 load C).....good, but can be noisy (gravel sized pebbles get stuck in the tread), not that good in winter (they are severe snow rated...this is very rare for an all terrain tire...might be decent for a 4x4). The previous set was Goodyear Wrangler AT/S 225/70R14....not very good IMO.
For age of tires, a rule of thumb is 6 years max. The Wranglers were gone after 6 or so years. The BFG are date coded as early as 2005....lotsa tread left (new tread depth is 16/32 inch). Will probably keep the BFG a bit longer than 6 years (assuming that I don't replace the truck with a 4x4 Ranger).
If you are looking for an inexpensive set of winter tires (studdable and directional), I recommend looking at the Hankook W409 I*pikes 205/75R14. Less than $100 per tire. For all terrains, BFG All Terrain T/A KO if you like the aggressive appearance, but don't mind the noise....it's a truck tire for sure.
