OK to flip RT-615?

Mirage · 01-30-2007, 02:21 AM

Did a search, but it didn't turn up anything..

My set of RT-615's are pretty worn on the insides, wearbar is almost gone (toe and camber for autox). Is it ok to flip them? Is the specified inside sidewall stiffer than the outside sidewall to make it not OK for flipping?

Thanks in advance.

Yes. As long as you understand that resistance to hydroplaning will decrease. If used in the dry or just slightly wet conditions, who cares.

Flip it!

Hey Ken...guess you better slow down at auto-x, let the rest of us in STS catch up then

Meh rt615s have no resistance to hydroplaning when they get worn down anyway. The biggest hassle with getting a tire like that flipped is a lot of tire shops won't want to do it...

Mirage · 01-30-2007, 04:55 AM

Thanks for the quick responses guys. They are my dedicated race tires, so I can now squeeze a some more autox's out of tthem.

I just hope they won't be dead soon from all the heat cycling.. lol

semaj.. didn't expect to find you outside of VIC.. are u stalking me? haha

Or won't do it period because they are not supposed to mount worn tires for liability reasons. Most shop will probably say, it's not their tires so they won't work on it.

Any chain tire shop will probably not want to do it.

If they are that worn, chances are they are already heat cycled out.

The tire shop thing won't be a problem, but now that you mention it, the heat cycling thing is making me think if I should just keep using them for the 3 last Slush events and just buy a new set.

If you can use them for 3 more events then I'd avoid paying for fliping the tires and potentially damaging your wheels by a shop.

Once you get your new set of tires, try to rotate them more frequently to avoid the negative camber wear effects. Even rotating just front to back and vise versa helps a lot too.

I meant if I'm not gonna flip them, I will just use them for 3 more events and throw them away. Cuz that's an easy $40 towards a new set.

To maximize their usage, I usually rotate them front to back every 3-4 events (average 15-20 runs), but all 4 tires are at the point where the inside wear is different than the outsides. Running camber front and rear as well as toe settings ruins the tires quite fast. Only way to avoid that would be to flip them sooner.. if that's what you mean.

WRX11 · 01-31-2007, 07:54 AM

^What camber and toe setting are you running? How many events have you ran with the 615s?

The $40 saving is what I was thinking of plus you save the risk of damaging your wheels from dismounting the tires. I'd put the money towards a new set too.

James@RPM · 01-31-2007, 11:40 AM

I got 5 days which is 4 20min sessions per day

I was running -1.5 all around with 0.2 total toe out in the front only. Mounted on 17" x 7.5" SSR Competitions.

On that set, I ran 12 events (average.. 7 runs let's say), plus 2 big events (2 days each) that consisted of 16 runs, and one special "team enduro" event that consisted of 3 runs in the morning, and in the afternoon a 90 second multi-lap run.. so about an hour and a half on them. And then the very very occasional drive on the street if I didn't change out the 615's between events.

I didn't think about the damaging the wheels part, but you're totally right.. no matter how good the machine is (diameter of the wheel is programmable), there is always that risk. I wIll try and get a picture up.. I might be overthinking this whole thing too, cuz the tread difference isn't too much..

I'm everywhere man

I didn't realize you were wearing through your 615s already!

Your setting and amount of use doesn't seem that extreme, I am not sure why your 615s would wear so different then mine.

I have slightly more positive setting in the rear and do use them for summer tires as well as AX. With regular rotations, I don't have the camber wear that you do.

Are you changing tire pressure at events and for the road at all?

Mirage · 02-01-2007, 02:06 PM

I do go back to a lower pressure 3/4 of the time for the drive home from the event.

I think its the toe and not so much the camber that causes it..?

Mirage · 02-05-2007, 06:24 PM

Just to complete this thread I started.. Here's the pic of one of the two worst tires before Sunday's AutoX. Since taking the pics, I don't think the difference is that much to waste money to flip them. Our AutoX lot is a closed runway on sandpaper-like concrete.

In the top pic, right side is the inside of the tire. Bottom two pic shows the treads from different angles.
