I dont recognize the rears, but they dont like like PS1's, like it has on the front.
Mixing different types or brands of tires, with likely different ages, a definite no-no!
I never realized how important this was, until one time when I put some new fronts on, then went out on the track, and found it had new-found oversteer!
The fronts gripped like glue, and so when I pushed it, the back end wanted to step out. It was a drastic difference, which surprised me, because up to that time, I thought everyone who ballyhooed about not mixing them up were just exagerating. My rears still had tread, and were the same PS1's, but were quite a bit older. THis alone was enough to unbalance the handling, never mind having different types, like that pour guy had.
Not original wheels, so at least not XGTZs.
I'll vote for the PS1s, but MXX3 middle treads had identical rows around and the one in the lettuce field looks like the center one is thinner... maybe PZero?
