I am the relatively happy owner of a 2005 xc90 2.5t awd with 190k on the clock,
I just moved to a new home, which is on top of a 200yd very steep gravel/dirt/rocks driveway (itself on top of a 3 miLes not-that-steep gravel road).
The driveway is not well maintained (I am renting) and there are big potholes and rills...the ride is very rough up and down. But I have always managed to climb up easily if not comfortably, there is a bit of spin/slip on the worst sections once in a while, but nothing challenging.
In the month I've lived here, my tires (Firestone destination LE) have been wearing off visibly!
I suspect the potholes have screwed up my alignement which hasn't helped. I know also my control arm bushings on the
Front are done and I will change the control arms next month.
Nevertheless, there are also more specific damages on the tires that come from pointy rocks obviously. They are of course not designed for this kind of ride every day or so. I will finish these tires very soon, and I fear when I will need winter tires ( I am in Colorado) I will destroy them fast

I am considering setting up A/T tires. I can find some used ones locally for a decent price...e.g. HANKOOK Dyna Pro ATM. In the right size (235-65-17). But of course the speed index is not what is recommended/specified.
is it doable to do that? Safe? Legal? Likely to help with my issue? Are they relatively good on the snow?
Or should I just resign, try to find a more "robust" car and sell the Volvo before I destroy it by using it outside of its intended use conditions?
Thanks in advance for any advice.
