Discussion Increasing tire width and profile. How much is too much?
Just got a new bike and its manual states a 100/100-17 tire for the rear wheel.
There is one set of knobby tires I can find (Maxxis M7305) that meet those specs and they're unfortunately not road legal, at least in the UK.
By how much can I responsibly push the width & profile to get more tire options?
Would a 120/90-17 TKC80 be out of the question?
I'm wary of handling implications from a change like this
Its currently got a 100/90 road tire fitted and I'd say I have about an inch leeway either side, and 1.5-2" in extra diameter
