I'm running a set of 235/75R15 ATs on my truck with the ultra grip.
They are insane in the winter. I plow with my truck and the locker does well, but i wanted a lil something extra.
dry pavement is just nuts, they hook and go.
wet pavement is much better. I used to get my ass end to slide all over the place, its hard to do anymore.
I drove somewhere when it was icing out and didn't realize how bad it was till i got there and went to get out and almost busted my ass.
i know the price has gone up a lil, but i paid about $65 a tire + about $75 to ship all 4 of them fedex.
they are balanced before they are molded, so they are almost perfect when you get them. I'm running about 3oz of airsoft pellets in each tire w/ no wheel weights.
my only complaint is the foot print. its huge. i've got them at about 50psi to reduce it, its almost where i want it.
all in all, i love them and plan to get another set when these wear down.
