Smallest Rear Tire Size

[DarkSideR]

I am trying to help Sweet Cheeks get to where she can manage her new 98 Tourer.

She is 5'0" short.

We have already bought 11.5" Rear Shocks. We will slip the front forks down 3/4" of an inch. It also has a Lowboy Ultimate.

If that doesn't lower the bike enough what is the smallest/shortest M/C tire that can be safely run on the rear?

I haven't run it. But this looks like the smallest I would run.

Not interested in D/S'ing this one. Looking for smaller/short Bike Tires.

That's going to limit it quite a bit. This MIGHT fit.

Don't slide the tubes up in the triple tree. The clamps needs to be at the large swell it the tubes to clamp right. Tried it and got a bad high speed wobble!  The clamps are design for the larger portion on the tubes.

Look at the rears for Michelin Commander II's.  They stick very good and wear pretty good, and have some oddball sizes.

With a wheel for a 180, I don't know how narrow a bike tire will work.  Also, it's a heavy bike, and the rear tire carcass shouldn't be too thin/skinny.  A smaller thinner car tire is going to be a heavier carcass tire (and safer), than a smaller thinner bike tire (I'm just saying) (guys who have run 175 and 185 car tires say it's hard to tell the difference from bike tires.... or that they are less car-tire-like in handling characteristics than the 205s most of us use; like wanting to stand the bike up in sweeper curves).  

This tire calculator can be helpful.  Plug in the stock rear size (180/70R-16) then start looking at smaller/shorter tires and see the differences.

yep 3/4" is much too much. only up to 1/4" can be done safely.

narrow the seat so the thighs are more straight downward.

Maybe the GL1800 rear tire? It's 180/60 x 16 vs. 180/70 x 16, and lowers the bike by a bit more than .5 inch. They're widely available.

Heard that referred to as a "Nose Job", and yes that will be the last thing we do to the bike.

Actually some Wing riders use the Valk tire to gain a bit of ride height.

Thinking outside the box, has she considered having higher thicker soles put on her riding boots. Most shoe repair places can do this. Every little bit helps.
