81 gs750ex tires question

[SixteenValve]

hi i am new to buying tires for this bike. stock specs call for 3.25H19 in the front and 4.00H18 in the rear. my question is can i put larger tires on, and if so what are the maximum size tires i can safely put on. also can i go tubeless? they have tubes now. thank you.

Hi,

The biggest tires I'd suggest is 100/90-19 on the front and 130/90-18 on the rear.

The wheels themselves should be marked if they are "Tubeless Tire Applicable". If they are not then you'd best use tubes.

Thank you for your indulgence,

BassCliff

And after having to trying to get a 130 off the same rim on my 78 1000 I would suggest a 120 is a better size.A 130 is REALLY squeezed on that rim.

I agree with staying with a 120 rear since the wheel is only a 2.15". The bikes running a 2.5" wide wheel can go to 130 though.
