Picture creds to @RyEnd
Fivestars rule 
I’ve been thinking about getting some, are you going to use the MBS pulley?
If I get these tires I’ll put them on a gear drive

looking for the perfect pneumie tyre size - I have this inkling that 150mm dia x 67mm flat wide would be the PERFECT pneumatic for racing where grip is everything. One day perhaps…
200mm is a little too big on the range loss I reckon. the PSI needs to be as high as possible.
Apparently Psychotiller almost got it with 6" x 3" (152.5mm x 76.2mm) - someone needs to bring these back.

Aren’t racing and range inversely proportional though?
Wide aside, larger wheels run higher speeds per rpm. Idk anyone building a race board for range as well.
But then again I also see a lot of racers using urethane so maybe it’s all just preference of track, grip, etc.

almost like race slicks! haha… I guess a urethane IS a race slick essentially. Just trying to figure out why wide wheels look so good on race cars like a Porsche or a Lamborghini, yet they don’t perform as well as smaller wheels requiring immensely more power for the torque, thus trying to find that perfect balance that will do well all round.
Anyway - it seems Psychotiller is intending to deliver the 6" x 3"s, so that’s exciting. Looks like Ernesto has 1st dibs on it though… a lot more interest on those than the 200mm x 75mms

Any idea where the rockstar pros land?
I dont have them
With ya there. Love my 6x2s. 8" tires are just too heavy for a lot of boards, can really make things feel sluggish if you don’t have silly power.

Are there any pneumatic wheels on the smaller side?
Total inflated wheel size <5in?

Kaly is developing together with another parts maker, a 6 x 3 inch version ,. that’s as small as they go currently.
