  • T8 including ODM's of Zero 8 and Bexly 8.
  • T9 including ODM's of Zero 9, Dragon X9 and Bexly 9.
  • KuKirin G2 Pro and other ODM's Mercane G2 Pro & Veloz G2.
• Internal diameter of 134mm (marketed), 132mm (observed with chamfered edge). 205mm external diameter (marketed, observed uninflated).
• Typical observed weight: 550 grams on Tuovt, 660 grams on HOTA.

Notes:

1. Not recommended (but a viable last-resort option) for use in Kaabo Mantis Urban, which requires a tubeless tyre such ax Xuancheng (factory stock) or ULIP. eSN has fitted the HOTA variant in Mantis Urban with success (has smooth bead, whereas Tuovt has writing on bead)
2. Tubeless tyres such as the Xuancheng and ULIP can usually be fitted (with tube) in lieu of this tube type tyre. The ULIP 8.5x3 is well regarded with puncture resilience.
3. VSETT / Zero factory pairs these models with HOTA 8.5x2 tube. eSN recommends the AoXin 8.5x3.0 long valve tube on motor hub wheels.
4. eSN recommends the Tuovt for ideal fit. Tuovt has been the Zero and VSETT factory tyre since late 2021. Models prior to this were factory fitted with HOTA 8.5x3 (A-3051) which presents similar in tread pattern and of similar 65kgs load rating but are slightly lighter at 414 grams. HOTA revised weight to 680 grams with the -A variant. The -A also has the ripple textured tread on the edge like the Tuovt.
5. Most T8 models (such as Zero 8 & Bexly 8) and select T9 models (such as early Zero 9) were factory fitted with a narrower Zero Branded HOTA 8½x2 tyre [A-3051] on front. T8 rear is 200x60 solid. The front 8½x2 tyre can be upgraded to 8.5x3 in Zero 8 and Zero 9 models (e.g. FalconPEV). MACURY Store, an AliExpress seller states their Tuovt and HOTA will not fit Zero 8 and Zero 9, however this is likely due to the bundled tubes having inappropriate bend/shape. The Zero 8 Pro runs totally different tyres.
6. T8-DDM such as Zero 8X is not supported as they run an 200x90 solid.
7. VSETT 8 rear is RISINGSUN 200x60 solid. You can consider the 8.5x3 (80-139) for solid to pneumonic conversion.
8. VSETT 8+ is also not supported as they adopt RISINGSUN 200x60 solid on rear, typically also on front (older models may be pneumatic front, in which case 8+ front is supported). Again, 8.5x3 (80-139) is understood as the right fit for solid to pneumonic conversion.
9. Keep tubes inflated at the nameplate 45PSI. Letting pressure drop to <40psi will significantly increase likelihood of pinch punctures with tyres of this size. Most of these models are split rim and relatively easy work on, ensure heat is applied to rim bolts if they are tight to prevent stripping head of bolts.
