Was reading the tire pressure thread and there is a lot of great info in that thread. I’m sure I’m not the only one here, but I’m not at the point where I could tell someone I like my tires at x psi or probably couldn’t even tell the difference of how the kart handles differently at certain psi. I also think it’s a very important skill to properly read tires as it really tells you the whole story to what’s going on.
So I thought it would be cool for members to post pics of their tires and we could diagnose them to see if we get them right. Then hopefully more of the experienced members could let’s us know if we were right or not. Could be a cool exercise and a very important one… lmk your thoughts!
So I recently flipped the tires and have I think one session on them in this configuration. So that’s why the tires wont make sense as far as how the are mounted currently.
So I would say the fronts obviously have substantial graining, which means they were oversterring? And possibly too much psi? I set all tires at 9psi cold FYI. Weather has been high 80’s low 90’s
As for the rears I feel the one tire looks fairly normal but the other looks over inflated to me by looking at it.
Again I hope the porpose of this thread is to A. help diagnose what the tires are telling you and know how to adjust psi and B. how chassis set up effects tire wear.
The tires look pretty normal to me Paul. I don’t see any graining on the front. Also, graining on the fronts indicates UNDERsteer, not oversteer.
Also, side note, I would avoid flipping the MG Yellows on the rim. We’ve always found that flipping them (especially the fronts) really messes up the camber of the kart and really takes grip away. They might start to come back as they re-profile from driving, but definitely the first few sessions you’ll notice a lack of grip after flipping.
Harder tires it isn’t such a big deal. But on a softer tire with an especially square profile, you’ll end up riding on a smaller contact patch if you flip them.
Seen some suggestions online that indication of to low hot tire pressure. Seem accurate? I noticed this past weekend regardless of how I entered pits I always came in with a TON of rubber pickup. Kart in front of me in tech line did not have same issue.
2: Rear tire inner edge coning? In general it seems that I tend to cone the inner edge of tire pretty excessively. Overall balance of kart seems ok just cone tire. 3 different tracks I have varying degree of coning but does seem excessive as when inner edge is down to wear bar the outer edge is still has about 30-50%.
Would you say the MG Reds fall into the soft category? Can they be flipped to use as practice tires and not mess up a driver? Is it better to just buy new tires so the driver is used to new tires?
They are a medium/hard compound. The MG Yellow is the medium/soft compound in the range. You can flip Reds, they don’t wear nearly as much as the Yellows.
However, you bring up a good point. It isn’t a bad idea to have your driver practice on new tires every once in a while. There is definitely a difference in driving and setup on fresh rubber.
I am looking for some help as well. On Vega Reds for for the 3rd time. My first 2 times tires came off looking great. No build up and rears looked like sand paper. After my 3 race it was a while different story. It was only left sides and didn’t go off track or out of the racing line. My top speed was continuing to slow down as the day went on. I’m still new and trying to understand. I have read so many different reports about tire temps and pressure. So I’m leaning towards the tire pressure to low and not getting hot enough.
