I had a lot of similar thoughts but I live where we can get a lot of snow
and mudd tires are not so good on packed ice and snow so they were out.
That left me with AT tires and in 255 75r 17 there were not many choices.
I had little 225 before and was little scared to go up to 265 where there is
more choice. I ended up going to with the Cooper Discoverer AT3. They
are a P rated tire so the ride is nice and they come with 14/32 tread
depth so the look cool and are 55000 mile tires.
I think now they are on I could have pulled off 265 and got the Duratracs.
