help please!

hey guys, I picked up a swing arm from a GS (i think) it said Wolf Racing on the side, anyway it bolted right up with just a 1/8" spacer on either side.

Anyway what I need to know is the largest tire I can fit on the stock rim as I have a tonne of room now with this swing arm, I want to keep the stock rims so I need some help as I can't finf the info.

thanks!!

120, maybe 130 unless you want huge chicken strips and a profile that is dangerous and useless.

I was afraid of that, the rim already has a 130 on it. Are there other rims that will fit the axle (front and rear so I can get e matching set).

do you have mags or spoke wheels on your bike now

spoke wheels, i think they are off an 81 csr cause they are magnesium.

Lace up a 3 1/2 or 4"x18 and then you can run something bigger like 140, 150 or 160

I have an Akront 5.5X18inch on mine with a 140 tire. I might be able to squeez a 150 in it. It looks cool!

a 5.5" rim comes with a 180 tire. it could go up or down 10mm. so 170 to 190. i run a 170 on my 5.5" x 17" rim.

Man, would I love to find a 5.5 x 18 Akront rim for sale here.
Anyone? Or any brand 18" rim, excel, akront, d.i.d.?
Don't want the new 17in style.
I want a 40 hole, 18" rim ring 4-5 inch.
