I am posting my challenges with replacement tires so others do not go down the same path .
I was looking for some DOT rated 10 ply tires for a Kubota RTV 1100 getting a Boss V-plow installed on it to get a weight rating of UTV + Plow + payload.
I thought the GBC Motorsports Kanati Mongrel Radial Tire (25x10R-12) was just what was needed.
Ordered them in - got them mounted professionally - attempted a balance, received a call from the service center requesting a visit to see for myself why they stopped the install.
Picked up the machine and its unsafe to operate.
The amount of lift and drop is extreme.
We lifted the machine and rotated each tire while mounted and got readings of 75% of tread fairly consistent and round 25% drops in almost 1/2" to more than 1/2".
We attempted to use the tire index yellow dots in line with valve stem and opposite valve stem - no significant improvement. GBC will not or cannot give indexing information.
Working thru the return process now but not holding my breath - Dealer and Manufacture both state since they are mounted they cannot be returned. I dont know how without mounting i would find the defects.
So from my perspective stay away from teh GBC Mongrels on the Kubota RTV's
If you do buy them don't expect them to stand behind their product. You can expect the hassle of mounting, un-mounting, re-mounting, attempting a balance for a tire that turns at slow speeds. Expect they will want video's of all 4 corners, and than expect that it will take you two weeks to even get noticed.....
Don't expect your dealer can do much more for you as GBC controls the process so I have been told.
So spend a little more money and buy a brand you have heard of.

Stay as far away from Hisun as you can, fit and finish nice but I bought a truck load and every single machine failed in the first 5 miles and took months to get parts. 5 out of 5 generators failed as well and they would not offer any warranty support! They set up dealers just to get rid of inventory. Units that cannot be retailed to dealers goes to the auction house and drives the value down, Nada wont ever put a resale value for Hisun on their website. They do not support dealers, I finally got my last one to the auction house and the throttle cable broke on it way to the selling line!
Its like throwing money away doing business with these folks... Run away and hide from Hisun as fast as you can! or just send me the cash!
I have changed pistons in my engine now and is done, head is on place and everything.
BUT now i saw in the joyner service manual that it was important that the connecting rods was installed "the right way" (D. When installing piston and connecting rod assembly into cylinders. The marked surfaces of the
connecting rod and piston must face the front of engine (fig.3-10).)
The pistons is correctly installed but when i installed the connecting rods i couldnt see any difference from side to side so i just put them back in and now one of them is "rotated" 180 degree if i looked at the texts on them.
So, does it matter? Is the manual a little bit "universal" or it is important? Has it to do with some oil lubrication? The only thing i noticed when i intstalled them was the bearing shell that has to be put back right so the notch goes in to the groove.
Anyone has any good answear to this?
