Tire Size

[Mop Bucket]

I am a tire noob and not sure what to get size wise. I was told I need front 90/90 19 and rear 130/90 16. The current tire in front is 100/90 19 but it doesn't hold air. I don't know if it goes flat becase it is old or if it is because of the size. I am looking at the Shinko Tourmasters and they only have 100/90 19 for the front. Will these work or do I need to find 90/90 19 to make sure everything works correctly?

I have a 1983 GS 650 G. Thanks

Hi,

For your bike the stock sizes are closer to 90/90 for the front and 120/90 for the rear. Most riders report no problems going one size up (100/90-f, 130/90-r). Do not go any bigger or the handling will be adversely affected.

Thank you for your indulgence,

Agree. 100 & 130 are good sizes for that bike. Shinko 230's are nice tires too.

Yup stay to your stock tire size, the bike was design with that size of tire in mind. One size bigger maybe okay but thats it. I went 2 sizes bigger on my GS750 that didn't last long, my handling went to ****.
