Hi all

Just wondering if somebody could help me with this.

A few months ago my back tyre was punctured by two nails. Biked shop picked up and replaced inner tube ~�80.

Now my front tyre is punctured also. Bike shop asked me to have a look at front rim for tyre size and rim size. It says 120/70 R17 M/C 58H.

Not sure what the 58H means but I think he just needs the 120/70 17 right? Also I am concerned because the tyres themselves say Pirelli (I think Diablo) and they state they are tubeless on the wheel. I thought you couldn't easily have tubeless tyres on spoked wheels? As far as I am aware, most of the things on the bike is stock. The rims are Excel rims which I believe is an option Yamaha give when buying the bike new.

So because the wheel says they are tubeless, does this mean they actually are? Or could they still easily have a tube in them?

My other concern is that the bikeshop might turn around and say that I need a new front tyre because it's tread isn't the bed. I know that in the next 6 months I will need a new front tyre. I just did my MOT and nothing whatsoever was said about the front tyre so I assume I am pretty safe with the ones I have for a few more months at least?

Thank you all.
