Gu6 Rear Gears

[cjriojas]

I have 17" denali wheels with 275/60/17 on her now. I don't know how much off of stock that is..... When I get the trans rebuilt I will put in a converter, I am just not sure how much stall to get. Does anyone knowe what the best posi is for a 2wd rcsb????

275 is width in mm which is equal to 10.82 in
60 is the aspect ratio which is the distance from the lip of the rim to the edge of the tire.
60% of 275 is 6.5 in
6.5x2+17(rim diameter)= 30in which is like zebra said, half inch shorter than 245/75R16
