AdamLGAnderson yes that is the dimensions of the tire. It will fit replace an 8.5 x 2. I suggest boiling the tire in water for about 10 minutes before trying to install it.

AdamLGAnderson i just literally used mine today(12-23-2020) in my vehicle (12v DC) while installing an alarm system. So it is capable of 12v.

AdamLGAnderson It doesn't come with either, just bare wires.

AdamLGAnderson after about 10 minutes of use mine quit working altogether. Really disappointing because it acted like it was going to be a nice device. The 10 mins. of use was in 5 separate 2 minute intervals. I've got a very nice variable power supply controllable to the 10,000ths (0.0001) for amps and voltage, so i know that couldn't have been the problem I would not recommend this product.

AdamLGAnderson yes the speaker in my watch gets REALLY loud i usually keep its volume on like 2 or 1 . Microphone works well too. if i could put up a video for you i would. its very easy to use watch as a phone.. u can also use gestures to hang up, answer, silence ringer. i love it for when I'm out riding my m365 kick scooter. hands free is awesome

AdamLGAnderson The app that works with these cameras is still on the google store page. Its called YCC365 Plus

AdamLGAnderson No,some of the control units will let you design the control of the lights but they won't let you implement your own software.

AdamLGAnderson Youare going to want more storage than the cheapest one.
