Tires tires /wheels

Does anyone know if there are any wide industrial type tires /wheels out there to fit 3110? price
thanks

There are plenty of tires. If it is 4x4 it is a little more critical to match size/OD. If it is 2wd it isn't. Check with Robert at Hey Wheel. He has made custom wide rims for me several times. The price is very reasonable. They are usually overbuilt. He takes lage equipment rims and puts custom centers in them. You can match the offset perfectly, or make them wide set. 785-594-3441 I attached an F 22 I put Industrials on.

Welcome to the group. Mine is a YM1500 but you can get some idea of what I did. I bought a pair of brand new 13.5" wide turf tires on John Deere rims that were about 1 inch in diameter less than the old tires. I cut two pieces of 7.5" aluminum and machined adapters to go from the 5.5" bolt pattern of the Yanmar to the 6" pattern for the Deere. Worked out great for me so especially if you are 2WD look at ebay for tires. Mine were 272.00 for the pair including shipping. Turned around and sold my rice tires and recouped most of my outlay. If you go to the link below you can get some more ideas ofd how I did it.

thanks for the info.it gives me a place yo start. I have a 3110d which is 4 wd. I just want wide industrial tires for the rear for wider stance.

Bama35640 · Mar 8, 2005

Ok glad to help. You need to measure the rolling circumference of your current tires and then match it to the new tires. A little harder than on a 2WD but most tire websites will list the information you need. The wider stance makes a huge difference as I found out. Also by going to the turfs I now longer bury the tractor if I hang up using the box blade or dirt scoop they will spin on the surface. As far as traction I have not noticed any less than before. Good luck.

Ok.Bama35640. Isee you are from morgan co. I'm from jefferson co. I bought this tractor approx. 1 mo. ago and don't know much about these things. Why is it harder to do this on a 4x4 than on a 2x4. That tractor looks good with those wide tires. /forums/images/graemlins/cool.gif

Kenmac:

It's the rolling circumference of your current tires that make it harder to do this on a 4x4 tractor that comes into play and you don't have much wiggle room on this, if you go wider and not taller it's not a problem (I think) It's when you start changing the distance each tire will roll in one revolution and if you don't keep it the same ratio the back will be pushin' the front or the front will be pullin' the back, and thats when your knuckle gears start strippin' or loosing teeth.

I think I explaned that right?

vongiese · Mar 9, 2005

You got that right Whiskey. And I believe they are designed to pull just a wee little bit from the front.
i'd like to get a pair of those fattys on my 2210 - looks way more stable. Would have to get now chains /forums/images/graemlins/frown.gif

Thanks whiskey. The wide stance is what I want,the current height is fine.I guess you are saying I can go with the same height or shoter tire & wheel, just no taller .is this correct?

Whiskey · Mar 9, 2005

Kenmac:

Your part way there, you can go wider (I think again) but not taller or shorter. Taller and shorter tires will change the rolling circumference.

Think of it this way, while your setting there and reading this get a quarter and dime out of your pocket and roll them one revolution across your computer desk bet you the quarter will cover more distance than the dime...well did you try it...was I right? Now think of the quarter is your back tire and the dime is your front tire.

The new tires you replace the existing tires with will have to roll the same distance as they do now. Now with that said....I bet your setting there and thinking "can I incress both front and back the same % in relation to what they are now" and to tell you the truth I don't have a clue...it's make my brain hurt to think about it!

The rolling circumference was set up by some guy with way to much time on his hands back in Japan at the Yanmar factory, and he's going to be real pissed if you change all his math and calcuation on his design, and just might show up at your door with a calculator in his hand and a pen protector in his pocket and screaming at you!

Bama35640 · Mar 9, 2005

Good description Whiskey. Just steal the wife's cloth measuring tape from her sewing room jack up the tire and measure it. Then compare that to the tires on Firestone and Goodyear web sites. You could also measure the front tire calculate the ratio and if you have to go to a different tire for the rear replace the fronts also.

You could go taller or shorter but your front tires would have to be changed accordingly. If you were to change your rear tires that were taller, they would be covering ground faster than the front wheels and the front wheels would essentially be skidding some. If you went smaller on the rear then the fronts would be going faster and would probably spin a little. Either way there would be stresses on the drive train that in time would result in something breaking. If you have ever forgotten to disengage the 4 wheel drive and tried to steer a vehicle on pavement then you know what it feels like. Going with a wider tire on the rear won't hurt anything as long as the diameter does not change.

Ever hear of pi? /forums/images/graemlins/cool.gif I like blueberry!!!!! 3.14 x dia = cir..

kenmac · Mar 9, 2005

thanks for all the info guys.if I can come up with all of the material ( tires& wheels the same size) adapter plates etc, I'm going to go for it.
ps, you should make those adapter plates and market them.

Bama35640 · Mar 9, 2005

I have talked it over with a friend of mine with a couple of CNC machines. Just don't seem to have the time for it right now. But if one were to need some I might be able to get my arm twisted and make a pair up.

If you are going to buy big wheels ,why pay for wheels and adapters? Hey will make wheels that fit cheaper than you can buy wheels that don't fit and still buy adapters.

Bama35640 · Mar 10, 2005

In my case I got the tires Gooyear TerraTrac brand new and the rims for 272.00 delivered to the door. Added about 80 bucks for the plates I made so for 350.00 I put some nice wide tires. I'm sure the tires alone would have cost well over 500.00 for the pair without the rims so at least in my case it worked out better.

It's actually a liitle more complex than figuring the circumference of a circle. This should be based on "rolling circumference" which takes into account tire flex, etc. A crude way to determine this is find a flat paved surface (or nice flat hardpack, mark the tire where it meets the ground and mark the ground - drive the tractor forward three tire revolutions and measure the distance on the ground and divide by 3 to get an average. It's different that tire circumference because the tire flexes and squishes as it rotates. Do this for your front and back tires to establish the ratio.
Firestone lists rolling circumference on their website http://www.firestoneag.com. If you want a better explaination of how to measure rolling circumference - click on the "Lead/Lag" tab at the bottom of the Firestone site. They also explain my previous point that the front tires always are designed to be in the "lead" by 2-5%.
As long as the ratio beteen front and rear tires remains the same as original ratio - you can put any tires on that thing that will fit under the fenders!

Ok, fine. I was replying to using the wifes sewing tape measure!!! I think if u used the circ. and kept the ratios the same u'd be ok without doing all what u said? /forums/images/graemlins/tongue.gif
