The ULIP 10x2.5" 140 gram tube has a reputation for resiliency due to the quality of material and presence of a reinforced valve stem. They also expand consistently under inflation.
Slightly larger internal diameter than typical 6" rims making it well suited for 6.5" rims for tyres such as 85/65-6.5 on Navee N65 rear (non-motor hub). Common 6" rims include those on Mantis 10, VSETT 10+, T10-DDM (Zero 10X, Dragon X10 & MiniWalker), T-10 (Zero 10), VDM-10 such as Bolzzen Dynamo & Gladiator, Dragon Raptor & e-Glide Mach 10, Bolzzen Commando 4822 (1st generation, yellow swing arms) / Dragon Slayer (Hota 80/65-6) and Mukuta (Tuovt 255x80).
The 45 degree angle is relatively true with 60 degree tilt, slightly more true than the 30 degree angle of the eSN thickened 120g tube. The 90 degree angle runs at around 80 degrees
