I have been looking at the Firestone Destination XT in a 31x10.5x15 but have concerns about road noise. I also looked at the A/T and A/T2. The A/T2 seems to be better for what I am doing but only comes in a 235/75r 15 or 28". Most use will be town and local highway driving with an occasional venture into the mountains. No hard rockin or rough bumpin. Does anyone have an opinion on pros or cons on the XT, A/T or A/T2? I would have like to be closer to a 31 rather than 28.
