Tire question!!
 

Howdy guys I'm quite new here. My dad and I completely rebuilt my 92 s10 blazer tahoe. She sat in a gravel pit for nearly 10 years. The tires are on 15 inch rims and they hold air well but they are all kinda dry rotted. I found some sweet 30x9.5-R15LT for only 200 bucks but i dont know if the tires will fit on the rims i got. please help!
