I am finishing up a cb500t and i am ready for new tires. Can anyone tell me how large of a tire i can use? I am hoping to be able to fit a 110/90-19 in front and a 120/90-18 on the rear. Whatcha think? The owners manual calls for a 3.25-19 and 3.75-18 Thanks

Both those sizes are too wide for proper mounting on the stock rims....
The 110 front is a full 1" larger in width and diameter, so problems with fender (and caliper during the install) clearance should be obvious....
On the rear, a 120/80 X 16" barely clears the chain ...as the proposed 2""larger diameter tire is installed, clearance with the chain, chainguard, swingarm and brakestay will rear their ugly heads....Not to mention the clearance with the rear fender during "bumps...

A 3.25 tire would be in between an 80/90 (3.15") and a 90/90 (3.54")....(closer to the 80/90 size)
A 100/90 is 3.94" wide.....Roughly a 4" tire.... Simply convert mm to inches.....
