Hi...I'm in the middle of creating a GS500 STREET><TRACKER and want to fit some chunky rubber on the front end...can anyone advise if a 130-80/17 tyre will fit without any rubbing issues concerning the forks?... I am aware that I will have to modify the front fender.

..hope you can help!!

Search up for gsJack tyre use charts.... he has used lots of sizes!

Sorry, can't help you with a 130.
NorthwestRider put on some chunky knobbies for a trip up to alaska, that might be the look you are going for?
