No man, nothing at all. No response. Normally, when you contac Alibaba they rely the inquiry to their provider(s) and they are the ones who answer later. No news from the Evolve 5 inch tires. 
I believe 5" tires are way too small to be effective. Thatās why you donāt see much. It was highly advised not to run 5" tires so I ended up settling on 6.3" tires. If you also run 5" tires they are only good for 5" tires while a slightly bigger tire you can always use the same rim to run a 7" or 8" tire.

Same here. Three messages and nothing. The donāt give a fā¦ @torqueboards what do you understand by effective? What were the arguments against 5"?

ā¦the argument that is a rim they donāt have (neither other manufacturers). So if they donāt have a rim for such a tire, then is not very convenient to promote such a tire, right? 
Some of the arguments are that a small tire will āwear down fasterā than a larger tire. But the again ā¦ shouldnāt the manufacturers feel happy because they are now feeding the market with new 5 inch tires more often (??)
Skaters love narrow trucks. They are becoming shorter by the year. Whilst Eskaters love wider trucks and bigger wheels despite the fact that we donāt require them by any measure. If we are right or notā¦the market is more than happy to provide Eskaters with wider truck and larger wheels, no?
@LukePL canāt remember the exact details but was something similar to what i mentioned above.
I think itās safe to sayā¦ if Evolve tried 5" but ultimately went away from itā¦ Iād imagine itās for good reason.
Ultimately, I didnāt bother with a 5" because I plan on releasing a 7" or 8" makes sense to use the same rim.
ā¦like for example?
Enertion also tried way back but dunno why didnāt stick with them

Nice! I just wonder why no one use presta valve? Its smaller and lighter so wheel would be less out of balance. This is 135x50 and those on Alibaba are 125x50. Looks like they did more of themā¦

Yeah!
125mm = 5 inches (4.92 to be precise) 135mm = 5.3 inches
@LukePL, I got an ideaā¦ perhaps we are looking in the wrong place for these 5 inch tire! We only need a 5 inch tire with 8mm bearing in the middle, right?
Why donāt we knock on the door of these guys (scooter manufacturers) instead?? They already using the wheel size we want!
ā¦first search and I already got one (not the exact width we are looking for) but is a startā¦
