having trouble finding answers need help!

well i have two questions first how do i replace the dome light bulbs in my 2000 chevy s10 blazer and second can i run 265/70/r16 on my blazer without having to lift it. also its a zr2 blazer.

Welcome to the site. For the dome light, the cover may pop off. If not, the headliner may have to be removed to get to it. I'll have too look at mine one day and see how its made. As for the tires, on a ZR2 I believe you can run 32x11.5x15 tires without any trimming or additional lift. Any larger of a tire and you will need a body lift and the flares would need to be trimmed. Stock wheels (both N90's and PA3's) are 15x7 with 6in of backspace. The tire you want to use is a 30.6in but you want to use 16in wheels. I'd say it depends on the wheel back spacing if that set up will work or not. May need a slight t-bar crank also.
