I've seen a 180 Metzler Marathon mounted on a stock wheel. I believe he did the washer swap to fit the stock swingarm. IMO 170 is the sensible size on a stock wheel. It's not really wide enough for proper fit of a 180.

I'd bet you'd notice no difference in the 180 Metz vs the 170 Shinko, if they were mounted on 2 Maxes sitting next to each other. The rim, being narrow by today's standards, wouldn't let the tire expand to full width.

+1, 10mm isn't a lot until you run out of clearance.a 5.5" wheel is required for the 180.
A 180 fits well on my Kosman rear wheel, but a 190 would be very close.

According to Ebay the widest rear tire that fits my "99 is a 150

170 will fit without issue.

Same size wheel '85-'07. They are giving you the oem size. They are not going to take liability recommending any other size than manufacturer spec tires nor do they try and see what fits and what does not. It has been noted you should not run a wider tire than the wheel was built for. That said, many of us do run 170's very hard with no mod whatsoever with no issues whatsoever. Choice is yours.

If you use the search function you’ll find that this topic has been covered almost as often as what’s the right oil to use. You are certainly welcome to listen to eBay or you can take the advice of the thousands of members of this forum that are running 170s.

If you want to do yourself a favor replace your wheels with ones allowing use of radials. I consider radials to be the #1 best move to improve your handling on a Gen. 1 and you have dozens if not hundreds of threads here on how to do it.

Just don't let me catch you "on the dark side," unless you're sportin' a sidecar.

I would not use EBay for my Vmax knowledge. You have the VMOA ! Donate accordingly.

Who ya gonna believe, eBay or guys who own Vmaxes? If you got a stock rear wheel, it will fit.

Or you can run a wheel like this, my machinist makes: 5-1/2" X 18" and very-close to OEM height, so you keep your top-end speed, which you lose some with a 17". But how fast do you need to go?

This wheel allows you to use a radial tire. You should use the same manufacturer and rubber compound f & r for radials.
