I’m suspecting that not all indoor surfaces should be created equal either. Tas swears his V2 are good on the indoor track we race on but you swear they suck.
I’ve not tried them to comment. Next time I’m there I will get some close up photos of the surface. It’s polished concrete but with a coat of some kind of paint and has also been roughed up with some sort of machine.
The v2s are up there with the best ive tried at our indoor track. However they absolutely sucked at 35PSI. It wasnt until i dropped to about 20psi that they were superb
Will try, thanks for the info!
Claimed the track record today on the MBoards Nova’s by 2 tenths (26.12)! Previous track record 26.35 and previous PB was 26.54.
These tyres got nice and sticky after about 3-5 warmup laps and they handled very well on the polished concrete!
Pressure at around 36-38 PSI which clearly made all the difference, as they were ridiculously slippery on my first session on them at 24 PSI
My new favourites, however I’d now like to pit them against the meepo cyclones for old times sake
Are they the 7"? Shame about the shipping to Australia. 75usd 
6 inch. 7 hurts, or so I’ve not been told 
What air pump set-up do you guys use to set accurate and consistent air pressures?
I have an inexpensive electric car pump from Amazon. (Car pumps are typically the same price but inflate a lot faster then electric bike pumps)
It’s not super accurate? It can get within a couple PSI. From there, I’ll feel out the board and adjust the psi with the ye’ old fingernail in the valve stem if needed.
That said, I’ve found NOVA’s traction to be relatively PSI-independent (compared to other tires), so I don’t worry about my tire pressure too much. I ballpark it and it’s usually good enough.
i use this one because it fits in my leg bag nicely

Can you get those disconnected without letting out too many pounds of pressure?
I primarily use this pump:
But also use a really cheap foot pump with a gauge from kmart, which tends to be pretty reliable in terms of accuracy.
didn’t see this, yes.
Just finished Waldshut.
First I tried the CST C190 9x3.5s, they were even worse then expected, felt like I was riding on ice just a little bit less extreme. This is a smooth bitumen / epoxy floor.
They actually worked decently in Pitland where it was a painted surface, although there I wasn’t really trying to pushing it super hard and never reached their cornering limit so I don’t know their max. But they definitely weren’t bad. Qualified 8/32 on them without pushing it too much and finished 13/32 with mostly chill riding.
In the end I was running the exway venators here in Waldshut and those did really well. Top 4 were all on venators. Tilo @TZDKB went 31.13 on them on an unprepped but fairly clean surface and the fastest gokart time is 31.9 on a prepped surface.
In the end Vic tried some landsurfs on someone’s board which he really liked at high pressure now that ambient was around 30C. He liked them more then the venators. @davidpilny didn’t like the landsurf that much in october (probably around 15C but just guessing). So those seem like they need the ambient temp and pressures high to really shine.
this is so f’n cool.
Hi Guys . Maybe stupid question, but when I see that You already tested few tires with different brands, rubber compound etc. Just would like understand how different diameters 150/165/175mm can influence Your result. It is clear that bigger wheel meen more contact area , but did You also changed Your gear ratio to be close with max speed or traction? Could this also influece Your times and not just rubber compound? Becouse I see that times are not so different. What about human factor, how long You ride on it and how much familiar You was with different setup? I do not want doubt Your results, just digging in to details to be it for me more clear.
You are bang on with this. This is something I’m always considering when comparing tyres that ive tested from 12 months + ago to now.
The beauty of the human factor though, is that you can also base some of your decision off “feel” rather than data. There are for sure some tyres that just instantly feel grippier off the bat, regardless of data.
Personally, on the indoor track, all the tyres ive tested so far have been around the 150-155mm range and not a large enough difference in circumference to justify any gearing changes. I would usually pick my tyres based on my gearing, rather than the other way around.
If we had endless hours on the track we would be able to truly pit the tyres up against one another within a single session, giving us the most accurate results but unfortunately due to the cost of the track hire & the time it takes to swap tyres, its not really feasible to test more than 2 sets in 1x 1 hour session.
Thank You bro 
Just adding to this too, the larger the tyre the higher the ride height and for racing I like to be as low as possible. I’ve run 7 inch pneumatics and 8 inch pneumatics on different setups and just feel too tall.
Just out of curiosity is there a good amount of rubber laid down at your indoor track? Or it’s clean? @Tasventouras @JeffyJ
I was recently at a track in Cologne, same type of surface as you run and same type as we run in Waldshut.
But Waldshut is clean track, here the track was full of rubber. (the picture shows pit area which was painted, it’s to showcase the rubber pickup of the tires, not the surface)
On the clean track @TZDKB didn’t seem to like the linns, and I absolutely hated my slick 9x3.5s. At that time I didn’t have my own set of linns yet.
On the rubbery track in Cologne I felt like the Linns worked quite well, can’t compare the 9x3.5s as I wasn’t running those. The only con of the linns was that they took way too long, about 3 laps of carving to heat up (could have probably been a bit quicker with higher pressure but I was lazy). Which in a race scenario would be unacceptably slow, but I was suprised that they were actually pretty good once up to temperature.
Although we couldn’t do a real comparison because neither of us could bother swapping the wheels for the exway venators which were our wheel choice on the clean track. And we also didn’t have any timing.
It’s usually pretty clean. And when it’s not clean it’s smore slippery. The surface doesnt pick up rubber at all. Any rubber is just loose debris that makes traction worse
