8x3.0-5.5 / 200x85 Tyre (tubeless) [Langfeite / Tuovt TD-8031]

• The Langfeite 200x85 with a diameter of near 7.8 inches, on a 5-5.75" rim, is an uncommon tyre that Langfeite exclusive adopted by Bike Scooter City on the discontinued original Dragon Cyclone model (the non-Pro, non-single variant being the dual motor model with 8" tyres, Langfeite C3-8). Running pressure is a high 70psi.
• The Tuovt 8x3.0-5.5 is typically fitted as aftermarket alternative on the formentoned Dragon Cyclone. Bike Scooter Garage who are familiar with this tyre advise to install a spacer in similar fashion to the eSN TurboTight Klima Fender Spacer Kit in the Dragon as the profile is slightly higher than the Langfeite 200x85. The spacing is undertake on the 2 front bolts fender bolts which makes the mudguard bow and for tyre clearance. The Tuovt adopts the more common 50psi. 70mm width at bead, 635 grams.
• Also understood to suit the Mukuta 8.
• Road tread.
• Due to the relatively small size hub, tolerances are tight - typically one or many specialist techniques are required to fit these tyres. Some skill is required to fit these which can be learned over time and through research. eScootNow considers these tyres suitable for experienced fitters.

Notes

1. These tyres will not suit 5" rim models such as those on Kaabo Mantis 8 / Sky 8S, for that size use 8x3.00-5.
2. First sent of product images show the Tuovt 8x3.0-5.5 followed by the Langfeite 200x85. Is understood to be manufactured by Innova for Langfeite, it shares the same TD-8031 designation.
3. Tips for fitting sub 6" tubeless:
   
   Being a relatively small diameter rim, fitting of these tyres is challenging for those without experience. The 200x85 measurements reflects the size when seated and inflated on the rim. If the hubs are wide, you will need high flow to inflate and form a seal tyre on the bead.
   
   You typically need to undertake a few techniques to have the tyre fit the bead of the rim prior to inflation. One method is to use a strap around the outer diameter of the tyre to seat the sidewall against the rim, being careful not to pinch/deform the tyre. Technique is shown in this video at 21h:11m: https://www.youtube.com/watch?v=n3PFbTdtSsk
   
   The high velocity airflow for inflation usually requires a compressor (visit to the service station if you don't have an air cylinder compressor). Temporarily removing the valve from the stem also allows for more airflow.
