DIAMOND Tread 9 Inch Tyre measure 4x 2.5x 9 230x75mm with 4 Inch Rim fits all 4 Inch Hubs

INNOVA's 9 Inch DIAMOND cut All Round Tyre is an off the shelf "Old Skool Classic".  Rest of this text needs Doing!! :-)

Its Straight-Cut 3mm line Grooved profile & ability to handle High Inflation rates makes this tyre perfect option for high speed easy rolling, working best on hard, packed surfaces such as Skate parks, Tarmac or Ashpalt.

Re-enforced with a 4 Inch Steel Band INNOVA's INLINE Tyre is "4PR" rated. PR means "Ply Rating", so this tyre has 4 Ply / Layers of rubber that are inter-twined with its inner structural threads. Most other Tyres in the TRAMPA range are 2PR, so having 4PR means its double thickness & therefore much stronger, more resistant to punctures and more capable of high pressure!! The extra strength in the tyre means it will easily handle much higher than recommended inflation pressures, making it perfect for all sorts of high speed applications. As a consequence of the extra material used & the extra strength gained means the 9 Inch INLINE tyre does carry a little bit of extra weight when comparing weight to other similar sized tyres.

The INLINE's 3mm deep, grooved surface, encourages the tyre to "Track" in a straight line, whilst the 9 inch inflated diameter is plenty big enough to glide over mini pot holes & handle mildly rough terrain easily.. Measuring 225mm x 60mm when inflated, this INLINE Tyre will only fit to the PRIMO 3 SPOKE Hub. The factory's recommended max tyre pressure is 50psi. Over Inflation of your tyres may cause the Tyre to explode and cause you an injury so please be careful if you try this at home...
