WHY do tires bounce/shake?


Recommended Posts

so i put some 22-11-8 cheng shin lumberjack tires on my banshee's rims and they shake like a mother fker. Cant get over 5th gear with out having a mini seizure trying to hold on to the handlebars. On my 3 wheeler they shake but thats only going 45 mph. So since my little 18 inchers need to go i found a pair of carisle turf tamer knobby style tires. IM hoping these dont shake but why do some tires shake and others dont??

I run 1/4 mile at 120mph+ and ALWAYS balance our American Racers with a bubble balancer and stick on weights. I had to do something because they varied from little vibration to so bad that you could see flashes of daylight under them as they went down track.

Yea if your rims are straight, hubs are ok, wheel bearings, axle bearings, tie rod ends etc. are good and theres not like a bunch of slime tire sealant in the tires then its just something that certain tires will do on 4wheelers not being balanced, you normally wouldnt have to worry about it on alot of 4wheelers because most utility bikes and stuff only go around 45-55 but on a banshee its a different story going 70-80+ mph.

You can have a shop balance them. Our dyno tires are balanced. (When they are going 100 on the roller, if they aren't balanced...your going to notice.) LOL.

You can get the adhesive weights and put them on the inside of the rim. We have a small Snap-on wheel balancer for doing ATV, Kart, Motorcycle and even small trailer tires. But a auto balancer might be able to do it, if they have a small enough cone to center the wheel.

Otherwise I've seen guys use the tapered cone style bubble balancer that was developed for balancing mower blades......... :shrugani:
