i see to still cut brand new KRTs at 25psi.
i guess its all how and where you put your foot down.
id skip on the crawlers, most people say the KRT is 90% of the crawler with 10X the side wall.
for a wreck wheeler IROKs or Pitbuls, or SX's seem to do the job if you dont drive like you stole it... which apparently i have forgotten how that works.
