Bounty Hunter Posted May 31, 2013 Share Posted May 31, 2013 Good points, but the charts on the web can still be plenty useful. It's still oranges to oranges because when you find the given RPM for your stock setup it also doesn't take into account the tire deflection you mention. So if you're not considering tire deflection when you start using the chart, tire deflection is not an issue on your final determination. This considering all tires are slightly over-rated in tire size. We know all manufacturers vary on stated size but it's my opinion the charts still have merit. But experience of Jeepers who have used several combinations is usually best. On 5/30/2013 at 10:42 PM, Eagle said: Sure, but that doesn't show up in a tire size chart. What I'm saying is that every tire/gear chart I have ever encountered (other than mine) bases their calculation on the diameter of the tire, without taking into account sidewall squat that makes the actual rolling radius considerably less than half the mathematical diameter.

FrankTheDog Posted May 31, 2013 Share Posted May 31, 2013 You won't be disappointed with 4.10's. First gear popped out all the time in my XJ so we always started out in second gear without issue. Drove it that way for 75,000 miles. Towed an MJ home from Virginia like that. That was with 265/75/16 load range E tires. Link to comment Share on other sites More sharing options...

However if I am paying to set-up gears anyway I am leaning towards the 4.56, especially after looking at the RPM charts and hearing peoples comments. The rear 44 is being re-built regardless and I'm positive I'll get my money back from the D30 with 4.10's I picked up. Link to comment Share on other sites More sharing options...
