Do I have a "real" problem ?

[arrow]

On guidance from another source I checked the listed factory specs between the the Solideal and the original Titan R4s.

It seems the diameter is less than 5/8 different i.e. 30.9 vs 30.3"

The original R4 that I replaced must be very worn compared to new.

I also found out from the original dealer that the T1530 started out as a lease vehicle in a nursery pulling wagons around. Could be the bulk of the 360 hours were on a roadway.

The data listed for original front tire size for R4's on this tractor are 25x8.50x14 which are 24.9 inches in diameter. The rears are listed as 15.9 industrials which are 40.4". If you have over 30" tires now on the fronts while keeping the rears the same, that is quite the increase in ratio.

The math is as follows: 40.4x3.14= 127" rolling circumference. 24.9x3.14=78" rc. 78 divided by 127 =.61 ratio for original factory tire installation.

For 31" tire: 31x3.14=97.3 rc. 97.3 div. 127 = .76 ratio. which is way more than the advised 2% plus or minus increase.

Of course all this being contingent on the actual rear tires that are on the tractor now being the original industrials from the factory.

HUH? a tire that has a 25" rim size has a -0.1 inch sidewall? I don't think so.

The R4 tire size on the T1530 for 2012 was 10-16.5. At least that's what the manual says.

I wouldn't think so either. The rim size is 14" however. Doesn't much matter as the tire listings at "Tractor Data" are incorrect. Needs to be figured again with the correct sizes.

So much for the "tractor data link:TractorData.com New Holland T1530 tractor dimensions information Thought these tires listed were too small for an over 3000# tractor.
The rears apparently are listed incorrectly was well. If you give them to me we'll figure it out again. Sorry.

Many sites I've looked at have the T1510 -T1520 data mixed up with the T1530 info -- the T1530 is a MUCH bigger frame size.

Those rears look at least 14.9 x24's or perhaps larger. Far from the size rear R4's listed on the site.

What the manual states & what is actually on the machine:

Front = 10 x 16.5
Rear = 17.5 x 24

I was cutting about 7 acres with the small machine & a 4' rotary. My kidneys approved the purchase of the larger tires and 6' Woods cutter.

My understanding is that the fronts are smaller because they wear faster than the larger rears and that generally the rears work harder and carry more weight thus allowing the small front to slip somewhat.

This is supported by the fact that majority of tractor implements mount on rear.

About the only exception is the FEL installations but even that is probably (in most cases) a rather small % of usage.

The front (generally) being lighter will slip more easily than the heavy loaded rear and so escapes damage.
Once the smaller front has worn down it will then lose its 'lead' and rotate at the same as the rear.

Another phenomenon will be that the largest powered tire will wear itself faster until it matches its mate as while uneven it will get all the power transmitted to it.

I venture to say that most tractors sport smaller fronts mainly because steering is lighter and easier and really don't work all that hard.
Fact is fronts are 'helpers', just that little bit more that gets you (usually) out of a bind.

Wrong.
,,,Equal torque will be delivered to each axle on an open differential. The consequence of this is that the tire turning faster will be transmitting more than 1/2 the power.

As to fronts, I think smaller ones are used because bigger ones get in the way in most tractor usage.
