need help quick. trying to buy some tires

[crawlin91]

Will they fit??? On my 91 supercab 4x4
mainly curious about the backspacing, will they stick out farther or tuck under the truck more (and possibly rub)

Lift: 5.5 superlift with 6" SJ softcoils and SJ 6" leaf pack

Tires: Mickey Thompson Baja Mtz 33 12 15 on a 15x8 rock crawler wheel with 3.5 backspacing?

$600 for four with 75-80% tread left sound like a good deal?
Anything else that I should look for? He said there were no plugs or patches. Also said he was running em on a ranger but I think hes got a 93-97 ranger.

Im going to go check em out tonight. He was going to measure the back spacing and let me know for sure but he thinks its 3.5

I think it would be a good way to get into some 33s on the cheap but dont want problems down the road.
