The galaxy tires are weak. They have no puncture resistance in them at all........Mine leaked around the beads and such, so I put Michelins on mine and they are amazing.

Got pics of your rig with the Michelins?

One of the rear tires started leaking 1 day after being delivered....brought the rim/tire in and it turns out the weld on the rim in the bead seat area wasnt ground down smoothly...Deere put a new rim on it and its been fine since.
I've loved my Galaxy's from the day I got em...did alot of brush & gravel work this past fall and they still look like new...

I am very used to my humor only impressing me.

Here are some pics for the Michelins I put on. Really like them so far. All I have really done is seed with them, but they leave such a nice flat footprint on the ground. And with two steel belts in them, they should be very good when I mow brush in the summer.

Thanks for the pics...
Those are really nice tires, looks like a cross between the profile of an R4 and the tread from an R1....
Did they have matching fronts avilable? Looks like you got the factory fronts still on it?

JD3520Turbo · Mar 23, 2009

You are correct, Michelin doesn't make a front that I needed.
I went one size bigger on the rears, so I had to go up a size on the fronts.
I put 28x8.50x15 on the front. That kept my ratio correct.
They do make a front and rear tire in the original sizes.
The rear is a 400/70R20 XMCL, and the front is a 27x8.50x15 XZSL. That setup would be almost flat proof.

I would love to have those tires on my tractor..... but does anybody know for sure if those tires will fit on my 3720 Cab unit... it seems as though they may... but the left fender on the cab unit also houses part of the diesel tank and there is less clearance on that side.... I wonder how much those tires would set me back if they did fit.. obviously I would have to change my front tires also to keep the gear ratio in sync...

Do you get better road speed with those bigger tires? if so how fast can your machine travel with those tires... I have the larger "filled" R4 tires on my machine, and I can only top out at an average speed of 15.5 mph... sometimes 16 mph if the grade is perfect..

The Manual says I should be able to get over 18.2 mph with my tires right now... I can't even do that going downhill...

which brings me to ask... is it possible that my dashboard computer was never set up right for my Larger R4 tires? What is everybody else getting for Road Speeds on their machines?

I thought the same thing...JD3520Turbo he went up a size...wonder if it was up from the already "Larger" R4's...if I were to swap over, I'd swap over to the same size I already got with the Larger R4's. But thats assuming I can get the matching fronts as I'm a little picky with that stuff..

Was your tractor delivered with the larger R4's or did the dealer swap em out for you there at the shop? I'd say your theory of the computer not being correctly programmed is entirely possible/very likely if the dealer swapped them out.

I would say his Michelin's are larger than the regular larger R4's, because after looking at pictures of other Open Station machines with the regular larger R4's, there is still quite a bit of clearance between the R4's and the fenders. On his Michelin tires, it looks like he used every last bit of clearance he could to get those tires on... I love the looks of them though... I would love to have those on my tractor, if they do indeed fit the cab model...

as far as my tractor goes... I'm not sure if mine was originally delivered with the larger R4's or not, Dave? I know I wanted the larger R4's and told them I what I wanted to be configured on the tractor, and it was delivered with them.... so I'm not sure if they came from the factory that way or not....

what is your tractor getting for Travel Speeds?
