Bigger tires for Gio Beast 200cc

cameron88 · 08-12-2009, 01:59 PM

talk about strange sizes, I am not a tire guy.

I would like to get some bigger rubber on the Beast so it handles better off road through rocks and bumps.

Anyone know the max size and a retailer that would carry them?
These are the stock sizes...
Rear Tire Set 18 x 9.5-8
Front Tire Set 19x7-8

Thanks for any input!

To assist you I am going to post what your sizes mean:

Rear Tire Set 18 x 9.5-8:

# Tire Diameter = 18"
# Tire Width = 9.5"
# Rim Diameter = 8"

Front Tire Set 19x7-8

# Tire Diameter = 19"
# Tire Width = 7"
# Rim Diameter = 8"

* a bigger diameter will lift your machine, but will alter the final drive gearing.

x2 what Reveeen said. Larger diameter tires will mean a higher overall gearing so you may find that you lack accelleration and climbing power. Are you wanting to gain more ground clearance or are you wanting a smoother ride over rocks, ruts, etc? If the latter, you might want to look more to the shocks than the tires. Tire pressure is also an important player in traction and ride quality. Shoot for 5psi tire pressure and adjust to suit.

In addition to the downside of less accelleration, taller front tires will put more stress on the steering and suspension components. I wouldn't go hugely over sized, perhaps a couple inches.

Good luck, you'll get a lot of great help soon I'm sure.

I think just by looking the 200cc Beast could use bigger rubber. The body kits are so high that they look under tired to me. I'm sure they work just fine, but definetely could use some bigger boots.

I've often considered buying new rims from Princess Auto (if they're the correct bolt pattern), just so I can install a set of the agressive Carlisle tires they sell. They look awesome, and I'm sure I'd gain considerable traction and climbing ability.

You got it Reveeen, looking for bigger diameter, not huge but a few inches bigger.

Power and acceleration I am not worried about loosing, i already have issues keeping the front 2 tires on the ground due to its power :P.
Everyone who has tried it says its just plain horney and wants to go like snot, and I would have to agree. Got the CDI ignition and 250cc carb on it.

The reason I want a bigger diameter, is for more clearance and better handling off road. Last time I was out I was gettting hung up on the rear end in some trails and got stuck a couple times off road.

Soo.... anyone know a supplyer that would carry these sizes? or any thing close?
Front Tire Set 22x7-8

# Tire Diameter = 22"
# Tire Width = 7"
# Rim Diameter = 8"

Rear Tire Set 22 x 9.5-8:

# Tire Diameter = 22"
# Tire Width = 9.5"
# Rim Diameter = 8"

What's your rear ground clearance now? 2WD ATV's are typically short in that department. My 300ex had < 6 inches.

Well ok.................

ANY motorcycle dealer will hook you up with tires, so look here to see what is what (available sizes and price) and check locally.

Just remember: too wide and you will be buying rims too.

What is your bolt pattern ?

Many are 4 bolt with 4.5 center to center.

If that is the case a Honda 200SX may have the same size hubs and axle splines.

You may need to replace the rear hubs @ 45.00 each and get a set of hubs that are setup for larger rims.

Big bear rims will fit some of the hubs, trial and error msy be required.

I have Yamaha big bear rims and tires on the rear of my northstar 250. The front was never changed.

In addition the front sproket was changed from a 12 tooth to an 11 tooth running a 520 chain.

this increased the rear ground clearance by 2 inches plus the wide big bear tires are good at very low pressures.

Doing this will slow your quad down but increase its ability in mud and steep rocky trails.

China ==> trial and error plus your own shop !!
