[QUOTE="ytradio, post: 436475, member: 19779"] 35x3.14=109.9 109.9 inches /12=9.158 feet per tire rotation 9.158 ft / 4.56= 2 ft of travel per drive shaft rotation 5280 ft per mile / 2= 2640 drive shaft rotation per min. To do 60 MPH with 35” tall tires. So in 3rd gear on your auto trans at a 1 to 1 transmission ratio, your engine should be turning 2640 RPM with 35’s at 60 MPH. I would think that this would be within an LS engines good rpm range for decent power. [/QUOTE]
