    gear ratio question

    if my current gear ratio is 3.30:1 and I install 2.5 ton rockwell with 6.72:1 ratio gears, essentially the exact double, then instead of 29 inch tires I should be geard for 58 inch tires, right?

    I would go ten percent lower for the extra weight of the tires lke 53 and it shold be geared just righ, right?

    it's mostly theoretical... It would have to have huge fendertrimming with a sawzall like that brown landcruiser that's floating around on here somewhere.

    I'm simply asking if the gear reduction would work like that. In real life, especially under a little range rover, I wouldn't want anything bigger then 44s

    Not really, in real life you face rolling weight Surface area etc. I know in theory your ratio would be the same, but to make it perform like stock it would need and increase in power as well. For example I have 3.73's stock in my Samurai and I run 34" tires so if stock tires were 26" I would only really need to go to 4.10 to correct for this. I have doen one better and gone to a 24% Increase through the T-case. This is like running a 4.62 in the axles and still it is not enough for the bigger tires to use the Hi Range offroad on anything but a flat surface. I have even gone one up on that with the addition of the 1.6L over the stock 1.3L. I would really need more axle gear to make it better, but with the Toys on there way in, I am not investing more time on the Stockers.
