As we thought MG will totally stand behind their tire, they will replace any that blistered during the event. A combination of new surface, really hot temps and small contact patch seems to be the culprit, not a bad batch of tires.. Wagner and Luis are first class guys and we should all thank them for what they do for Colorado Karting…

“Blistered tires normally come from the lack of tire wear. If the tire doesn’t wear the surface gets hot (the shedding of rubber cools the tire). The material under the surface starts to overheat and “boils” the compounds within tire?s entire composition. The materials separate, leaving a void or blister. If you look at that area the appearance is the same as a pumice rock. The holes are the areas were the gasses escaped. “Mike hit this one dead on. As many recall the situation at MMP last year and the 1st big race at the Track, now the first (big race?) at IMI this year new surface, little rubber down. The solution was to heat cycle the tires. It worked (for us) at MMP it worked at the track and it worked at IMI. A 5 minute session at 50% is approx. all it took. Worked for practice tires on saturday and we used the 7 minute session Sunday morning to cycle them. Of course you can only tell your butthead driver like Keenan to go 50% ( he turned his only 51 on the first lap of morning warm up before he toned it down) and hope they listen because we have seen it work several times now.
Hope this was helpful or as usual maybe I am full of it. LOLCraig
At the IMI The Track Rmax race there in June it was 105 degrees in the shade according to the weather pod. We never had and trouble with the MOJO D1. Maybe we could look at using the MOJO then us rotax guys would only have one setup to work on for both series.
Ok, Let me have it!
NO GO ON THE MOJOS! We have had hotter days without tire problems. I think this last batch of tires is the problem.
Whatever it was. It’s pretty scarry sending your driver out there knowing he’ll be running 80 Mph on a carcuss of a tire.
Here’s Matt Kistler hanging on!

Looked like the kart was working well till…
This is what Tyler’s front right looked like after the last club race main at IMI. Is this tire wear or did it blister or both? I bought these from Barry before the 2nd IMI race this season. I thought that these would last close to all season on a lighter JR2 kart.

We thank you for your support.
Matt Kistler,
You’re one hell of a driver! You did an excellent job of “waiting for it” to turn in. Especially impressive is the need to put your hand on the bottom of the wheel to force it to turn. Way to hang on buddy. And this video is heavily shortened. You’re my hero.
Curt, you make a future comment about his driving from the fence I’m reminding you of this.
Hopefully, as mentioned in this post, it’s a one off deal that won;t be a factor again.
Hats off to all the others who had this condition and made it to the end!
Barry, thats awesome of Mg. I met the importer in Vegas last year. What a good man! True supporters of the sport, not just out to cash in on us.

Thanks for the “YouTube” post Rick. Sorry the result of our inexperience on the camera was “pixely”. According to my smart son, Dave, we will need to use a different resolution next time so the quality will be better. The CD version of the entire day is very good quality and we will run it at this years award banquet.
The video tells it all however. We did heat cycle our tires, did loosen up our front end bite, did set the pressures lower, did change the way Matt turned in, (as wittnessed by Keenans pass on turn 3) and everything else one would do when tires are blistering. And they still blistered in both races. We had no issues on Saturday with the same temps running in the 51’s all day long.
I will agree with Blink. The batch of tires from MG were not right. And they are a class act by standing by their product. MG’s are the best tire we have run on in 9 years of doing this.
Thanks again Rick for posting the video. :cheers:

That’s just a worn out tire with the cords starting to show through. No blistering as far as I can see.
Jeff,
One of Matts tires blistered and it was diagonal across the face of the tire and was new at the beginning of the session.
If I didn’t know better, it looked like a worn out old tire to me too.
Huh, that’s strange. The blistered tires I’ve seen have always looked like the picture my dad posted of Greg’s, or the left front tire in that video of Matt, where the rubber rolls off to the side.
So I retract my previous statement. Can’t tell well enough from the picture – could be blistered, could just be worn out.
In all of this I have to say.
The Mg is the best, most consistent tire we’ve ever run. It has great longevity and grip. Every manufaturing proccess is subject to tolerances. We had a questionable batch in Utah, we were given new tires. They are standing behind their product here too with offering replacements.
After meeting the importer at the Super Nationals last year, what a great guy who loves and supports what we do.
Still the best tire and as Barry said, it seems to be brought to the surface by newer race track asphalt.
