Curious, what size Wildpeak AT4Ws were you running?Anyone running Wildpeak AT4W? Had a great experience with the AT3W so decided to go with the newer version, ended up spent a few weeks chasing vibrations and pulls. Turned out 3 of the 4 tires were out of round, and the other one had to do match mounted to lower the road forces.
After everything was done and alignment confirmed. It still drift to the right so I am suspecting one of the tire may have radial pull.
I had a set of 265/65r18 AT4Ws for about 6 months that could never balance properly ... 4 different attempts from 2 separate (good) shops. I eventually had them taken back by Discount Tire under warranty and switched to BFG K03s. Its interesting to note that most of the Wildpeaks are made in Japan, while a few sizes (including the ones I had) are made in Thailand. I've wondered if they have different QC process and tolerance across the two facilities, as folks buying other sizes don't seem to have issues.
FWIW, I am happy with the BFGs although they are D-rated and you can definitely feel the weight.
