Running 180 Rear
« on: December 05, 2015, 01:28:01 am »
I've not found any discussion on this topic, and seeing as there are a few extra options in this size - I was wondering if anyone has run a:  180/55zr-17 on their TT

Other than it being only approxiametly 1.7% smaller, cheaper and more models available...

A 60 series would be about 1.1% larger but there are very few models in that size anyhow....

Triumph engineers specified a 190/55 tire for a reason. I will trust that they know what they are doing...

Smaller diameter means even less accurate Speedo.  Turn in could be affected, but probably not that noticeable to most riders.

The best sport touring tire made comes in the stock size.  What options are you looking for?  Cost?  If cost is a huge concern on a bike that cost what the TTSE cost, then maybe you chose the wrong bike .  If it is availability, most places can get tires overnight.

Seriously...?   :491:

Any comments from someone who has ridden a 180 tire... feel free to PM me, apparently not a friendly question in an open forum to ask...

brbo,

Perhaps if you could explain a bit more about WHY you would want to consider
changing from the tyre / tire size specified by Triumph ?

I understand twowheeladdict's point on the cost thing -
but maybe there are other reasons such as a Make / Model of tyre you like,
which you have difficulty sourcing in the specified size ?

Better grip, Change of Bike Handling characteristics, Purchase cost, Rate of Wear,
you have an unused spare in that size and wondered if it would be ok, and so on,
could all be valid reasons, and knowing why might help Members provide more targetted advice  :028:

Cheers  :821:

I've run Michelin on the road for past few decades, and will continue to do so for my riding season tires and have no issue with the OE size

However I chew up a set of tires on an Iron Butt run in 7 days - with 3 planned runs this coming year, I have a specific tire I run that doesn't come in OE size which I've used on my RT in the past and very happy with -

I was simply hoping for some comments from folks that may have run a 180 on the TT was all...guess I'll have to report back as the Ginny pig...

I don't necessarily advocate it but if mileage, not handling, is your primary concern there are some IBA members who advocate going to the "dark side" and there are a couple of threads on this site with numerous posts, both pro and con

Sorry you found my post offensive bro.  I was just trying to figure out why you would be asking the question.  I am more used to seeing questions about larger tires for the look.

How about trying a Michelin Commander II.  I have 22,000 miles on the rear tire on my Voyager.

I would go that route before going car tire.  You can get a 200/55-17.  Maybe it will fit and the Speedo will be more accurate.
