They look basically perfect to me.
Could you explain a little more on what you mean as far as " The front outside edge seems a little too far in." Not sure i understand correctly.
Sorry. The toe wear on that top tire, It look ever so slightly inwards. Probably normal and is that camera angle is slightly more oblique on bottom pic.

I always assumed that the rubber builds up on the inside like that because as the tire wears, since we are mostly turning, it sort of sheds to the inside of the wheel. I guess the rubber gets a bit liquid when hot and accumulates there. That doesn’t seem excessive or anything. Someone more experienced may have a better idea.

Looks like good wear to me.
The inner shoulder will always wear more because of the kart’s front end geometry.

Makes sense. Thats why we scrub our tires and run into each other on the formation lap.
I’ve always found the inner wear and buildup to be more pronounced on a less rubbered up track. Basically a sign that the kart is sliding and the driver is having to counter steer mid-corner. Same symptoms in high grip conditions can be an indicator of over driving.

There was very poor grip in the track, as it was the first practice of the season, so it makes sense:smiley:
The track was also very dusty, so i have a lot of cleaning to do:crazy_face:
Didn’t get a photo of the rears but this Was fronts after 100 laps, 10psi
My rear end was very loose sliding all over the place
Can’t read anything with all the marbles you pickup
The LeCont white above for exemple are quite good but the setup ain’t perfect (back-end pushing the front and little to high with pressure)
Yeah a lot of marble pick-up on there, hard to read exactly.
Looks like some outside edge build-up, which to me would be indicate slightly too much caster. Which would explain the oversteer.

Some of my tires do this (rear only), the pressure and kart setup is good. It only happens when you drive on the limit and if you listen carefully you can hear it.
Does someone have an idea what could be causing this?
That’s odd looking. It’s like it’s coning the tire but only on the end closest to the axle. The rest of the wear is parallel to the ground.
The rubber at the edge of the tire appears to be flaking. Is this old rubber?
Not that unusual. I see wear like this on tracks with a lot of faster corners usually. New Castle springs to mind.
What tire/pressure and what circuit?
Typically I don’t try to tune out this kind of tire wear unless I’m concerned about tire longevity. Wear like this, for me at least, doesn’t necessarily indicate a handling problem. We have fixed it before by using a longer rear hub.
At the inner edge there is aome old rubber but I always have that
Circuit berghem, kinda comparable to genk but less straights. Tire pressure of 0.9 bar, mojo d5
I wonder why that channel died. Last post was years ago.
Col got out of Karts either sold or let lapse his Kartbook website and sold his Kracer business to DPE (Arrow Manufacturer)
Not sure why, but he looked burnt out to me. Kart book especially became a dumpster fire of political arguing that got out of control.
Trying to moderate that would be enough to turn anyone away and shows what a great job @KartingIsLife and his team (hopefully there is one) are doing.
Kartbook .net somehow became owned by a foreign entity and the sites security was compromised (lots of fun emails /s). The data was moved over to Kartbook .net.au so I think it is all still available, but its not the community it was.

Hello guys
Tires diagnose is something I am also trying to get better every data analysis I do. Due to that, I bought that Mychron 5 Tire Temp Sensors in January this year.
I always use MG red tires and I got from their spec we should try to keep tire temperature between 80º and 95º to get the best performance of it.
The thing is that I am since Feb this year collecting data and trying to reach the range of 80/95 but it is almost impossible. I am changing tire pressure and some kart parts like wheels, hubs and rear axles to increase the tire temp, but here are the averages I got from my last 73 runs.
I use to start the session with cold 9.5psi at the outer rear, 10psi at the outer front and the inner rear, and 10.5 at the inner front. Usually, I return with hot 13.5psi at all tires but very different temps between them.
The gap between outer and inner tires temp is always almost around 10ºC.
The track I weekly train has a poor asphalt surface and is very slippery.
My questions are:
Should I keep trying to reach the range between 80ºC/95ºC as the manufacturer recommends?
Will I never reach the recommended range of temperature due to the low level of grip of the track surface?
Should I keep trying to have the same temperature at all tires at the end of each session?
Should I keep trying to have the same pressure at all tires at the end of each session?
@alvinnunley, as the AIM Tire Temperature Sensor (https://www.aimtechnologies.com/kart/kart-infrared-temperature-controller/) measure just the temperature in the center of the tire, I have just bought Alfano Tyrecontrol 2 (pressure and temperature gauge) (http://www.alfano.com/new-tyrecontrol2/) with the needle tire probe and infrared sensor, so I can have quick surface temps reading and deeper tread temp information when needed.
Therefore, I´d like to ask if you could share that excel spreadsheet you showed previously you use to make your tire temperature analysis.
