Rim width and tyre size !

[Aleksandar13]

Hi All,

 

I am hopefully converting the T7 in a hybrid supermoto soon if everything works well... I will be using stock rear rim and order a new rim in 18inch for the front . 

 

Question is : What rim width do I need to run 120/70/18 tyre ? 

 

Choices are at the moment : 

 

1 x 18-250-36 aluminium rim 

1 x 18-300-36 aluminium rim 

 

Would really appreciate some input in regards to size of the rim.

 

Thank you,

Aleks

The wheel builders should know that and give you advice 100% I would say.

 

But, normally for SM wheels you run a 3.5 width front. Some do run 3, but that's on the smaller bikes I believe

Hi Rich, 

 

He did mention that both the above are going to fit 120 wide tyre... Was just looking at a second opinion. 

The dark web says 3.0 as attached in the picture. 

Want to be sure before ordering the rim.

I'd say you definitely need a 120 front tyre with the 150/160 rear. 

 

Therefore, I'd go for a 3 or 3.5 ideally. No point in having a narrow rim as you won't need a skinny front tyre as per off road.

3.0 is the only option from this supplier in 18inch... I can get 3.5 in 17 but that's gonna look weird I think. 

Paint yamaha blue and some sticky tyres.

Sounds like a plan. You could be the first person in the world to do this, which is pretty cool. Bet you won't regret it!

That's right.. But it is not actually a supermoto... I think its called motard isn't it? 

Not sure maybe you know better.. 

Turn in should be better and bike a bit lighter as well....

It will be better on road, I guarantee it. Not that it's not good on road in the first place of course. In fact, it's amazing considering it has a 21 inch front wheel.
