It seems that tyres are always an issue partly due to the escalated prices and different wear patterns , road holding , longivety and of course off road capabilities.
Just my viewpoint :
I have driven through the years different vehicles from Mazda Drifter ,Isuzu and now Toyota.
Do not excempt my OU WA here 99 Blister.
It is true that every vehicle /bakkie or 4x4 has different charateristics to different tyres.
I am a big Pirreli fan as they did excellent on all the bakkies except on my Toyota for some reason flat spots within the first 5000 km. I had the rep from Pirreli out and his comments were- a common Toyota problem.
Now I have Hankooks on - a bit noisy but so far done 64000 km and still going strong. No imbalances , flat spots etc.
My colleagues all have BF Goodrich on and the same issue - flat spots, heal and toe wear, and not the kilos they were expecting from their Toyota's as well
My problem with Bridgestone mud terrain is loud noise, wet grip very bad and after 80000 km cracks developed longitudinal in the tyre. Now I have to replace all 4 RRRRRRRR
Just to add more confusion what about Silverstone Mud Terrains

Anyone heard or experienced them.
Must add I have seen almost all bakkies in Zimbabwe uses Goodyear as my customer says thet handle bad roads well - offers great wet grip and last up to 90000 km .
