Utv hisun 250 sector 2018

[Hud373]

Just bought this hisun sector 250 and it vibrates in rear going down the road.

Better define "vibrates"< could be a gearbox gear or bearing, or wheel bearings, a bad suspension or strut bushing, or an unbalanced tire/wheel?

[Hud373]

Thanks can you use beads to balance tires?

[cliffyk]

Probably not--over the years I have tried them with little success in motorcycle tires, they "sort of" work for a while but then break down into a fine powder inside the tire. Also it takes pretty good speed to get them distributed and these are big-ass heavy tires...

[Hud373]

Thanks for your input.

Vibration goes away at higher speed.Thanks for your input.

[cliffyk]

With big heavy tires like these it is not unusual for wheel/tire vibration to  appear at lower to medium speeds in rather narrow ranges. Also, keep in mind these are 4-ply nylon tires--they will develop flat spots when sitting in coldish temps (even at 65° to 70° F)  overnight. It can take a bit of driving for the rhythmic "thump, thump, thump" to go away. Modern steel belt car and bike tires are usually just 2-ply of polyester or rayon and do noy do thius.

Would turf tires be better?

[cliffyk]

I don't know, or care to know, squat about "golf cart" tires--I guess they'd be better for driving on grass. It's the nylon fabric that flat spots, if the thumping doesn't go away in a mile or two you need better tires, not a different tread pattern...

Turf tires are made more for "not tearing up" the turf... I would go through mudding or off roaring with them
