Front, rear or Does it Matter?
« on: April 30, 2022, 11:02:46 PM »
I just got back from Aotearoa (Land of the Long White Cloud) where I have half share in a MG Roamer.
While I was riding I discovered the original rear tire was completely worn out 11,000 KM (canvas showing), being Easter with everything shut I had to wait until Tuesday before I could locate a new 150-80 x 16 Tyre, it seems like this is an unusual size, none of the local dealers had one in stock, it had to be ordered in. I settled on a Pirelli MT66F 150-80-16-F
When I picked it up imagine my surprise when this large tire only had an arrow for front mounting. Because I was due to fly out in 2 days instead of leaving the bike with no rear tire I elected to use this tire on the rear. It certainly looks like a rear tire.
I'm wondering what the implications could be down the road.

Just fit arrow backwards
Loads are opposite front to back (braking v acceleration)

If I HAD to fit a front tire on the rear. I would have it fitted revers of the front rotation arrow. The inside is supposedly built for it to turn one way under load. Now if for some reason the tread pattern looked way off, I may do different.

There are tires that can be front or back. They are marked with 2 arrows and marked front or back.

I would ride it as needed. I would likely change it to a correct direction tire shortly.

Yes, I did that, I am familiar with the tires with arrows in both directions this is the first I have seen with only one arrow.
I think it may have been intended as a front for a heavy bike like a Harley so perhaps it will be fine on the V9 with limited weight and power.
Thank-you Gents for the input

Kiwi, I think you are correct regarding the weight and power of a V9 not being particularly hard on a tire. Might be a good idea to check load ratings and such to make sure the tire is in spec. If you're at all uncomfortable with it, order in a proper rear tire and keep the current one as a spare.

In Ambassador days it was accepted practice to put a new steering tire on and move the old tire to the back, reversing the direction.

In the old BMW /2 days you could rotate wheels front to back. Both wheels were splined so they could be switched.

Thanks for all the response, I may never see this bike again, it will probably end it's days parked in my Bro's garage with 11k on the clock.
The V9 is a nice bike but i'm glad I chose a V7

WTH uses that size tyre on the Front?
Harleys apparently if you look at the image I posted.

It's an ugly looking tire, I would never have chosen it by choice.
