Lead lag question.

[SwampCat]

How do I find the ratio for a B7510 HST with R4s. The fronts are Titan 23x8.50-12, and rear is Titan 12-16.5. Time to start thinking about new tires as these are full of sidewall cracks. Some early looking indicates Titan no longer makes the exact rear tire anymore. Any ideas or advise is greatly welcomed. Thanks. I guess what I am trying to find is the gear ratio of the drive train, is this listed in the WSM ?

Current tires listed as
FRONT TIRE
R10101 FRONT WHEEL(6-12) [B7510DN [OPTION]]
R10102 FRONT WHEEL(23*8.50-12)
R10103 FRONT WHEEL(21*8.00-10)
R10104 FRONT WHEEL(23*8.50-12)
REAR TIRE
R11001 REAR WHEEL(9.5-16) 120
R11002 REAR WHEEL(33*12.5-15)
R11003 REAR WHEEL(31*15.5-15)
R11004 REAR WHEEL(12-16.5)

Front axle
Ring = 23 Teeth
Pinion = 10 Teeth
Axle ratio = 2.3

I don't think your looking in the right places or for the right sizes?

Already have the fronts, found the right size and upped the ply count. Trying to do the same for the rear. Stock is 6 ply Titan. Titan makes, or made, these in 6,8,10 ply, 33.6 tall. Cant find the 8 ply, and the 10 ply that I got last week were defective, so they were returned. Spoke with someone at Titan who said this Trac Loader SS model was no longer made, if they know what they are talking about ?? Wolfman, thanks for the links. Reason I asked about the lead, lag is none of the other 12-16.5 are 33.6 tall. Most are less. Another pair of the 10 ply Titans are schedualed to show up tomorrow. Stay tuned.

Don't look at height, look at circumference (Cir). If not found can be calculated
PixR square (Radius square x Pi)

As in 24 inch tall = 12x12 = 144x3.14 = 462.16 inch

In country slang - Pie are not square, pie are Round

Circumference is 2 X Pi X R not Pi X R squared.

Your right, to many piston volume calculations
but the Pie are round is still good, right?

Absolutely!

The FedEx truck showed up with a pair of GOOD tires. Hopefully set for the next 15 years.

Be careful with Titan tires. They do not follow the Tire and Rim Association standards.

This link is not a lot of use as you need a membership to get to the tire and rim specifications.

My brand new M7040 came with Titan R4's. When I had trouble with TRYGG chains, I learned my rear tire was 3" smaller in diameter than the standard. This made my exact tire chains 10" too long.

This is the TRA info I do have. The first image will be rotated 90 degrees to be able to fit on the screen.

If you operate on hard surfaces inn 4 WD you might be wise to determine the proper front to rear ratio has been achieved.

In the end, Titan ignore me. Thankfully, TRYGG took back my chains and modified them to fit the tire size I have. I wont buy Titan again so when I do buy new tires like Firestone or Goodyear, then my tire chains will be too short.
