Hey y'all, appreciate any input here. This is my first time posting, though I've been reading for years. I was so excited to get my new RE-71R's for my birthday. I put them on a second set of wheels just for autocross so I could make them last longer. This is my first significant jump into "performance level" autocross.
But to my dismay, after one event one of the tires got torn up pretty bad. This can't be normal can it? It's worn down the middle section like this:
You can see how uneven it is. That edge is worn down about halfway already compared to the rest of the tire.
The other three tires aren't as bad. They look like this:
So weird how it only happened to one tire, and only down the middle. Like I said, any input would be appreciated, any experiences you can share. I'm just trying to figure out how to avoid this in the future.
thanks
More details below:
- I used chalk on the sidewalls to monitor pressure; I ended up letting a couple pounds out of the front and more out of the back during the course of the event. The chalk method always worked well for me with previous tires (the stock tires, then the Indy 500s). Using that method, I normally end up doing the same thing, taking more pressure out of the rears than the fronts. So I'm not sure what went wrong this time. The fronts did wear down below the triangle indicator more than usual, but I didn't think it was that bad so I didn't pump any more air in during the event.
- I sprayed water on them after a few runs, which I had never bothered with before. This was on a very hot Georgia day, with 8 one minute laps. At one point, a friend touched my tires and said they were really hot. That's why I sprayed them after a few runs, and did it every time after that until the last lap.
- Unfortunately, no, I don't know if these were on the front or rear (there's a longer story behind that)
- Even though I didn't put them on until I got to the event, I left them on for 5 days after (also part of the longer story). But I took it easy on purpose for those 5 days. Come to think of it, I didn't air them back up right after the event, I waited until I got home. That means I drove an hour on the highway at autocross pressures. But when I got home, I aired them back up to normal street pressure after waiting for them to cool down.
thanks again
