8.5x3.0" Tube 90 degree [JY-01]

• The 8.5x3.0 JY-01 tube Suits 8.5" tyre on 5.5" rims where valve extends at 90 degrees with 75 degree tilt. This tube is identical to the HOTA tube but heavier and with a more generous valve length (around 8mm longer HOTA tube). It is a great option for any of the makes/models listed on the HOTA Tube Page such as Zero 9 & VSETT 9 series, or if the AoXin long valve tube is unnecessarily long.
• Often paired with 8.5x3" tyres such as the Tuovt or ULIP.
• Typical weight 108 grams.
• Reinforced valve.
• Nameplate: embossed 8.5x3.0 JY-01 (blue line).

Notes:

1. Image below shows the predecessor to current stocks, which was very similar (including size) but lighter at 80 grams, without reinforced valve and nameplated in white with 8.5x2 which is a naming convention similar to that of HOTA ("8.5x2 for 8x3 tyre"). You may find older tubes in 8.5x3 tyres are marked as 8.5x2, like the one below - for these, replaced with what is now more commonly marketed as a 8.5x3 tube, as typically 8.5x2 tubes are skinnier and not suited to 8.5x3 tyres. The product images with comparison of 5 tyres shows this older version (embossed XDV852-11 B23 as KS:KY-TRE063).
   
2. Images below contrasts the Tuovt brand tube (left) with the predecessor mentioned in note 1 (right) at ~5PSI. Both have a 90 degree bend, however the Tuovt (left) has a tilt of near 90 degree rather than the 75 degree of the one on (right). It was observed the Tuovt (left) was lighter (~70 grams vs 80 grams). The Tuovt developed a flat when running in Tuovt 8.5x3 tyre. It is observed the Tuovt did not inflate uniformly which may have contributed to premature failure from pinch puncture (marked silver X).
