Help pls: min. residual? 120 for rear tyre?

[doletotodole]

I read the JPN manual, there is a line lin Japanese like "groove residual" below the tyre specs, saying 1.5mm for front, 2.0mm for rear.
Do anyone understand the meaning.

My concern is, as I plan to install a 120mm tyre for rear, should this mean the min. residual between tyre and fender, then, 120mm tyre will get this out of spec.

Thank you.

I'm confused. the 1.5mm / 2.0mm is just minimum tread depth to ensure that the tyre has sufficient ability to extract water from under the tyre in the rain to minimise the chance of aquaplaning (never a good thing on a bike!), and also ensures you don't get a blowout at 100km in a loaded turn because the tyre got too thin in the centre (if it gets flat on the outside - but is still rounded on the inside - then eventually the two "meet in the middle") (I've run two rear tyres too low and been lucky that I was only going slowly when they deflated - I won't run a rear over 10,000km now - just not worth the risk to life and limb to save a few $$$).

In terms of tyre sizes, my strong recommendation is to stick with what the bike is designed for - which in this case is a 100/90-14M/C

I believe it refers to what @TheMaverick is talking about, tire tread depth. Not about tire and fender clearance.

Thank you, Sir.
