The following forumulas calculate what Tire Size is recommended for a Tracker with Specific Drivetrain Components, such as Auto Trans, 5 speed Manual Trans, Ring and Pinion, Stock Tracker Transfer Case, and Stock Samurai Transfer Case installed in place of a Tracker Transfer Case.

Please keep in mind these calculations are for HIGH RANGE ONLY!  If you have a Rock Crawler Gear Set in the Samurai Transfer Case, the Tire Size will not be reflected correctley in the forumulas below due to the higher HIGH Range Ratio. (Stock Samurai Transfer Case HIGH Range Ratio is 1.409:1)

The Tracker Transfer case (So far) can not have it's HIGH Range Ratio Modified.  Currently ALL Rock Crawler Gear Sets for the Tracker Transfer Cae have the Stock 1:1 HIGH Ratio.

With out further due, Enjoy....


Tire Size Recomedation for Tracker with Following Drivetrain:
Transmission     = Auto
Transfer Case    = Stock (Tracker T-Case HIGH Range = 1:1)
Ring and Pinion  = 4.62 (Stock Gears for Auto Trans)

                            NOTE
Calculations are for HIGH Range Gearing.

EXAMPLE
(Tracker CALMIMI gears / Tracker Stock Tires / Tracker Auto-Trans 4.62 Gears) 
5.83 (clamini gears) X 27" (stock tire size) / 4.62 (stock r&p's) = 34.071
5.83 Ring and Pinion good for 34" tires with an auto tranny!

End of EXAMPLE

4.30 X 27 / 4.62 = 25.12 Tall Tires   (Tracker / Toyota Gears Non overdrive 2dr auto 1.6L 16v Gears)
4.56 X 27 / 4.62 = 26.649 Tall Tires (Toyota Gears)

4.88 X 27 / 4.62 = 28.519 Tall Tires (Toyota / Grand Vitara  Gears)
5.00 X 27 / 4.62 = 29.220 Tall Tires (Ford 9" Gears)
5.12 X 27 / 4.62 = 29.922 Tall Tires (Tracker / XL-7 Gears Most all 4dr's (Non Vitara) *  Most all 5-speed Track Kick's * Most all Autos with overdrive Gears)
5.14 X 27 / 4.62 = 30.038 Tall Tires (Ford 9" Gears)
5.29 X 27 / 4.62 = 30.915 Tall Tires (Toyota / Ford Gears)
5.37 X 27 / 4.62 = 31.383 Tall Tires (Ford 9" Gears)

Re: Gearing Chart for what Tire Size with what DriveTrain Components
« Reply #1 on: March 21, 2006, 01:26:15 PM »
This helped me decide to go with the following for my 97 Tracker. (Until I change my mind again)  ::)

Trans = Auto
Front 3rd  = Toyota IFS 3rd with 4.10 Ring and Pinion
Rear Axle  = Toyota Axle with 4.10 Ring and Pinion
Transfer Case = Stock Samurai (Kicker 1)

4.10 (Grand Vitara  / Toyota Gears) X 1.409 (Samurai T-Case Stock High Range) = 5.7769
27 X 5.7769 = 155.9763
155.9763 / 5.12   (Stock Manual Tranny Tracker Gears) = 30.464 Size Tires
155.9763 / 4.62   (Stock Auto Tranny Tracker Gears) = 33.761 Size Tires

The best part is, that the Toyota Rear axle is 58.5" wide (86-95 trucks/4runners), and I already have IFS 7.5 Toyota Diff.  :)

Another plus, is I could keep my current 5 speed and wheel with 30x9.5x15s.  Then when I ready to jump up to 32's or 33's, I just have to replace the 5spd with an Auto.

This will hopefully require a lot less fab work instead of installing a Ford 9".  Plus, the Toyota stuff will be a great upgrade for strength and can easily handle 35's.  Just have to figure out how I'm going to link up the Toyota Rear.

Or, after the Toyota Rear is installed, I could just install the Vitara 3rd and it would not required any mods in the front.  Only thing is, then I'm limited to 4.10 or 4.88 Ring and Pinions.  Making the front and rear diffs both Toyota, would allow me to at least have 4.10, 4.30, 4.56, 4.88, 5.29, and 5.71 Ring and Pinion options.

Or... I could just swap in the Vitara 4.10s,  I guess that would be the easiest!  :-[
