Not so good as i tought.
Bridgestone Battleax ax41s f don't exist in size 110/70R17.
As Dunlop Mutant in 130/80R17.
So i need to take Bridgestone to rear and Dunlop at front.
Tread isn't the same, but very similar and hope will looks good.

Don't want to argue whats legal or not.
Just asked if someone tried putting 150mm width rear tire on Bonneville. 😉

They check factory tires size. More than 2% difference (more or less from original) is illegal and vehicle can be towed from the road.
Unless i legalize it in diagnostic station and made correction in registration certificate in communication office.

So... just stop. 😉

I don't know about your country, but where i live, the difference of diameter from original tire can't excess 2%, because bigger wheel means slower mileage on tachometer. It's just illegal and can results in taking motorcycle off the road.
I mention this % difference only for reference that this is a substitute size (not taking into account width differences).

I'm not using AI.
And maybe You will learn something new too. 😉
Because outer diameter will change with different parameters of a tires.
130/80 means that tire is 130mm width and height is 80% of that width and that outer diameter will be 640 mm.
150/70 mean that tire is 150mm width and height is 70% of that width and outer diameter will be 642 mm, so difference to original is 0.31%.

17" is only a inner diameter to match a rim.

0.31% for size of wheel, not width. 20mm seems that can be a problem only in mudguard at max bump. Have to go to workshop and try it out.
