hi guys,

My tyres are coming to the end of there live now, pretty much got no tread on them Rolling Eyes

The tyres on my bike are really thin compared to some of my old bikes you cant really lean much round corners, The front tyre is 90/90/16 and the back is 120/90/16. I remember reading somewhere you could change the first two numbers of the tyres ones for width the other for tread ? ? If any one could clear up the confusion and recommend a new size and a make of tyre, that would be great!!

also how much am I looking at roughly, for two new tyres plus fitting ??

thanks !

If you put wider tyres on your rims you WILL ruin the handling. The bike will lean far more than you believe on skinny tyres, you just need to make sure the tyres you fit are quality and not Triangle or Wanli or Goodrides.

If you fit wider tyres to narrow rims, you'll end up with an incorrect profile on the tyres front and rear which could have a nasty effect on the handling.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Never had a problem with 80/100/17 and 100 80 17 tyres, they are skinny Laughing

Best bet is to find your actual correct tyres on ebay, being that small...fitting yourself shouldn't be too hard.

hi,

thanks for the quick reply guys!!! So happy I posted here first haha I could have had a nasty shock. Putting in the tyre sizes online I get mostly Pirelli tyres in my results, are these decent tyres or cheap crap ??

thanks

As above - sometimes you can get away with changing a tyre size; usually going up or down '10' you can get away with.
However no point unless you can't find any tyres in your size.

Fist number is width, second is profile, which is height relative to width, then the last is your rim size.
