Recently installed a 2.5” lift & RC UCAs. Ordered a set of falken wildpeak at4s 285/65 20s. Couldn’t install them because they were against the UCA. I found this odd because the 275/55s on now are said to be 11.3” wide.(falken WPs at3wa) The at4s were said to be 11.2”. I’ve also saw others in multiple groups running the 285s or even 12.5 wides & claim no spacers. Checked a co workers truck & his factory control arms & stock tires are very close as well, around 1/2” if I had to guess. Anyone have any input on this?
