Terra or trail grappler? and what size
#3
305/55/20 is the same diameter,and a little bit wider.These tires will fit no problem.I had the TerraGrapplers before on my 05 4x4 Daytona,and performed well in all environments.Only issue was that on cold mornings the tires seemed to have a little bit of a knobby feel to them taking off at slow speeds until the tires warmed up a bit.But after the tires were up to temp,they were as smooth as silk.I have never owned the TrailGrapplers.
