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.
