your bolt pattern is 5x4.5" on the rear 10" rims (assuming you stay with 15" wheels), would be a 5.5" backspacing. on the 8" front, a 5" backspacing. keep in mind that good SPEED RATED tires in 15" are tough to find !!....the best I could find were dunlop GT qualifiers with a TR rating (114mph), but i am only using my car for normal hwy driving..........GOOD LUCK !
