looking to get the widest tire on the stock rim.
I know this topic is beat to death,but it seems that one brands 170 may be wider than anothers.which has been found to be the widest.

A Metzler Marathon 180 fits the stock wheel and swing-arm. A washer swap might be needed,and people have done it . I've run 170 15"Shinko Tour Masters with no issue or washer swap. I think with the stock wheel width, 170 15" is a better choice. The 180 fits a 5 1/2" width wheel right.

Yeah,don't want to go to a 180.just wondering which of the commonly used 170's is the widest.I'll be using a notched arm.

Can a 180 really be safe on a rim designed for a 150? I know people use 160 and 170 but I've never heard of anyone using bigger without changing a wheel. Why does anyone spend money on wheels for a 180 f you don't have to? 30mm is over an inch wider than a stock tire, seems drastic. I'm not being smart here, I am actually wanting to know the answer.

well 170 is the widest that you can fit a 170 Bias ply tire.....A 180 RADIAL will fit, if you buy a rim designed for a radial.

So.....some of it is 170mm VS 180mm...but most is Radial VS Bias ply.

The Avon Venom 170/80-15 on the back of my Max fit with maybe 5mm of clearance between the sidewall and swingarm. No need for the washer mod either.

Thanks man,I figured 3/16". I like the tread pattern on avon.

The Avon Venoms do really well for biased ply tires. In my opinion, they are the best ones if you choose not to go with radials.

Why the notched swing arm for a 170 width tire?

+1.....its not needed. With SOME tires.....you MIGHT have to do a washer swap....but I didnt have to with a stock swing arm, and the shinko 170.

I've got a 17" by 180 tire mounted in a stock swing arm. I've got 4mm space between the arm and tire. A 190 would almost squeeze in there. With a notch, no problem, or a washer swap. The 17" does fit a little different. I like the way she handles with the 180 back and 120 front though.
