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.
Have a stock 2017 Stampede 4 door XTR. Looking for a spare tire, such as a front stock setup. Quoted from the dealer at $366.00. For a thousand bucks I can get a whole after market setup of 4 and use my original front for a spare. My stockies are 27x9r14 and 27x11r14's. I was thinking of going to 29's. Does anyone know if they will fit with no rub? All the dealers don't know. If anyone has an extra front wheel/tire they want to get rid of ?

I recently purchased a 2020 Massimo 400 EFI and began installing soundproofing to lower the overall body noise. The model I choose is the crew cab with rear facing seat and diamond plate bed.
the first phase involved removing the rear deck and applying Noico 80 mil sound deadening mat over the exposed diamond plate sections of the underside. This immediately removed the sound of vibrating metal plate!
Next phase is to continue this application to the interior of the plastic around the engine compartment and then any other plastic panel that has a "hollow" sound. It will add 2-3 pounds to the overall vehicle weight but it makes a huge difference in noise reduction. One question I have - there is a vent directly in front of the engine (behind a drivers leg about calf level) I am strongly thinking about covering this as the level of engine noise here is huge. The engine is water cooled so I don't think this is a problem as the air input is minimal - but i don't wish to overheat the engine.
Hi, I just purchased a Massimo MU500 that we are going to use in the North Georgia mountains.
After the first couple of test drives it seems a) somewhat underpowered and loud as hell.
So wondering if I switched out the mud tires with something with smaller tread if that would maybe help?
Also I found a muffler replacement called the “silent rider atv silencer” and wonder if that would help with the noise without killing power.

I have a 2018 Massimo MSU 500. I have looked everywhere for performance parts and all I have been able to find is the dyno bost module and a K&N air filter. does anyone know of any other parts out there or interchangeable parts from other makes or models?
