does anyone know how wide of tires can i put on a 2.5 inch body dropped 98' S10 with bags?????????

best thing to do is leave some stockers on there, and slam it, and measure what kinda clearance you got... i would assume you took out the inner fenderwells?
see how wide you can go in there... but ive seen 245s in the front slammed, you can fit alot in there.

dont forget about your offsets too...

i have 235/60/14 on the front of my truck dropped 3" with the inner frnders still in place and i still have like 1cm clearance between my tire and swaybar, i don't remember my offset right off but i think its just stock s10...
