Alternative Tyre size
« on: November 28, 2019, 06:34:09 PM »
Hi All,
In the process of ordering a new set of Metz Tourance Next for my 2012 Explorer and I got to thinking that since all my riding is road based and the odd slow group track day, I wondered if I would be better off with a slightly wider front tyre. Was thinking of a 120 x 70 x 19 instead of the standard 110 x 80 x 19. Does anyone have any experience of trying this or indeed any comments. Many thanks. Mike

Some folks will do this and be happy with it. I wouldn't. If you mount a wider tire in a narrower rim, you are pinching the tire a bit, which will change its profile from what the OEM intended. MTCW.

If you like the look of a bigger tyre, and I agree that the Explorer has missed out here, go for the wider tyre, I hardly think 5mm each side is going to be an issue, but CaptainTrips is correct in saying it will pinch the tyre and change the profile.  I put a 160/70 on my rear, mainly to gain a little more ride height, and had no issues. Please note that by going to the 120/70 front as you mentioned, the front tyre will have a slightly smaller diameter. MFCW  (as 2 cent pieces are obsolete here!)

I mounted the 120 front and 160 rear on my 2014 and had no ill effects on the handling, just did the same on a friend's Tex and he's happy with the change too.  I think any of the pinching that is happening is very minimal and in real time riding, there appears to be no difference.  YMMV  And as far as fitting the Tourance Next, I would highly recommend something different.  Those Metzlers came new on both my 2017 and 2018 T1200 and really disliked them.  Much happier with the Road Smart IIIs.  Might try the Conti Road Attack IIIs just for fun, been hearing positive feedback on them too.

Agreeing with pcarnut.  What profile front tyre did you and your friend decide on, I might try that combination next?  Conti Trail Attack 3 for me on the next change I think if the sizes are available.

Went with 120/70 front and slight correction here, went with a 170/60 rear. HTH
Regarding the Contis, I tried the Trail Attack on my 2017 and thought they were just okay.  I had used them on an Africa Twin and was very pleased with them so it was a little disappointing to not be as pleased when mounted on the Triumph, can't tell you why.

would you be better with a 100% road tyre?

I'm using Avom Storm 3D, not the newest tyre, but good value and good enough for advanced rider training in the wet.
I've got my first Triumph

Are those later rims a straight swap?
