Note no UTQG is given, but similar sizes have 500AB, which seems reasonable for an all-terrain tire. I also do not know if you have steel or alloy wheels, but that tire is technically to wide for 15x6 steel wheels, but would work on 15x7 alloys. Also it seems a bit heavy, is a LT rated tire really necessary for how you are using your Tacoma?

Just for the sake of pointing out other options, if you were to consider P rated tires, there are similar sizes that are a good bit lighter such as the Michelin A/T 2, which is only slightly shorter (2.4%) but is 18.8% lighter. Even if you “derate” the max load of the P rated tire by 10% for truck use, you will still have a similar load capacity.

If you are willing to go to less all terrain tires and more street able tires, you have options such as the Michelin M/S 2 which is similarly less heavy, but according to the UTQG should have a much longer tire life.

If you are uncomfortable running on “street tires” in the winter, you may consider looking for a cheap set of factory takeoff wheels from another Tacoma and doing a summer/winter rotation. Not necessarily because you need crazy mudders to get through the snow, more for keeping from ruining your good all terrains pounding the pavement all summer. Notice that most all terrains have a UTQG “B” Temperature Rating.

(Sorry the tables with the tire info are messed up.)

I'm not up sizing any then, I already have 235/75 R15
I will have to check whether or not the width of the rims is 6 or 7 inches
