Evening, looking for some help. Im looking at Maxxis Advantage (rear) and Ardents (front) and they both have 60a and 70a options.

Whats the difference? And more importantly, which type is better?

Cheers

Andy

    The higher the number the harder the rubber compound. 60a is probably their 'Maxxpro' blend, which I quite like. Harder rubber mean faster rolling and harder wearing, but a bit less grip.

    It's to do with the hardness of the rubber - a lower number will be softer - which will grip better, but wear out faster. A higher number will be a harder compound - less grip in certain situations, but more durable.

    As for which one to go for - It all depends on the type of riding you do/how much you're willing to spend on tyres! But 60a is not that soft - thaat would be my recomendation

    It is the stickiness of the rubber compound, in laymans terms the lower the number the stickier, usually grippier but wears faster and drags more. Opposite is true of higher numbers.

    Cheers guys, thats kinda what I thought. I will check the difference in price and see which makes more sense.

    Thanks

    personally the 60a would be the better choice, very popular compound with maxxis riders, they also do 40 and a 42 as well so 60a is more like a half way house

    To give you an idea of rubber hardness, see below:

    20A = Rubber Band
    40A = Pencil Eraser
    60A = Car Tire Tread
    70A = Running Shoe Sole
    80A = Leather Belt
    100A = Shopping Cart Wheel
    ..
    After uphill there's downhill

    Where did you find that out because I'm sure it's false since for one, you get different compounds on car tyre's just like bike ones, funny that, and I do not wear my super tackys (42a) out as soon as I lock up on a rock. Oh, and running shoes also have different compounds so that must be false as well

    Thanks Peter. Probably best to tell these guys: http://mykin.com/index.php/rubber-hardness-chart
