I took the stock run flats off at 500 miles and replaced them with non run flat a/s3s. I busted my ***** for 2 hours getting the run flats off. How I didn’t put a mark on the rims is a miracle. I won’t be putting run flats back on. Way too much work. If an air pump and sealant is factory issue in my Porsche it’s good enough for my Vette.
Foosh or anyone who cares to answer, ZP & non-ZP aside, is the Ackerman Effect diminished with the AS3’s over the PSSs? And is that what the issue was all along or just road noise in general?
If you mean the tire "jumping" at full lock when turning then, yes, it is practically eliminated with the AS3's on a Z51.
I have a coupe and would like to minimize the tire road noise.

This kind of talk falls on deaf ears around here, even though its exactly right.
Worse than that, the clique of run flat lovers in this forum, will absolutely insist on removing the tire and patching it from the inside if a puncture occurs; as though every tire machine and tire shop is prepared to do this job.

I shared my story and observations strictly for someone reading it to take in to consideration. There is no right or wrong answer here. Each of us has his or her own risk threshold and acts on it. I stick with run flats but choose to fly 75 year old airplanes. Many would say that’s crazy.
The great thing is that we have the choice to make and can make it as we see fit.

It is Michelin that instructs an inside plug patch (center tread block only) is the only approved repair and required to keep the tire's speed rating and warranty intact. It's not a runflat issue, it's an all tire issue.
Exterior plugs are not accepted by any tire company on any tire as a proper repair. It is considered by all tire experts as a temporary, emergency repair. And yes, I know, I've heard anecdote after anecdote from folks about how they've had them last forever. There are also a lot of stories over the years about many of them blowing out. You can play that lottery if you like.

Yeah I get it, and to your credit, you at least think these sorts of things through as far as possible. Which is why you probably agree there is nothing structural about a patch, and a plug from the inside is the same as a plug from the outside, so you would be playing the lottery either way.
Regardless of all that, you cant avoid the additional difficulty associated with mounting and dismounting a run flat tire. So what happens in real life if you have a punctured run flat tire, that is repairable, but its the weekend and your nowhere near a big city tire shop that can mount and dismount a run flat tire ?
This is the point (at least partially) that Dez`sC7 was making, and I agree with.

On the positive side while you and Foosh dissect details, Im out testing the new AS3+ and loving them! Better ride for sure and absolutely NO wheel chatter, that to me is worth it..I have to assume they will also last longer on tread wear. Risk=reward until I get a flat, lol!

Im getting the AS3/+ non RF tires this weekend.. Best option IF you get a flat? Slime, compressor, tow, etc? Thanks
My $45/month Sprint cellphone plan also pays for my yearly AAA membership ... AAA will flatbed-tow my vehicles to Discount Tire (24/7) for free... Discount Tire will likely fix the flat for free... and then I'll go pick up my car when it is convenient to me.
He'll get the correct tire. The AS3 is no longer available, as it was replaced by the AS3+ about 3 years ago. He'll also be purchasing the ZP version, since non-ZPs aren't available in wide-body sizes.

No, I absolutely do not agree with the part in bold above. A combo plug and patch is very much structurally more sound, because the inside patch and plug are attached, the patch is glued to the inner casing and air pressure inside the tire pushing on the patch does not allow the plug to blow out. A plug only with no inner patch can dry out, shrink, and blow out.

Sure, a flatbed is a good solution if you don't mind waiting an hour or more on the side of a busy freeway when it's 10ºF with the wind blowing at 30 mph, and you've left your coat at home. I sure wouldn't want to be sitting in the car on the shoulder for that long. I'd rather just keep driving.

Thats why you need to move to warmer climate! Its only 80 here today!

Ok so to clarify the context here, we are talking about a dismounted run flat tire, because that was the post you responded to, and we are assuming that one has found a tire shop who will service a run flat tire. So if I plug it from either direction, then cut it flush on the inside, buff the plug and liner, then glue a patch on it, is the structure of the tire restored ? Or is the only way to fix a run flat by using a special plug patch combination ? And if that's the case, do you think this reduces or increases the chances of getting the tire repaired in an emergency ? Because it seems to me the more you talk about these run flats, the more stipulations there are when it comes time to fix them, and not everyone lives within 30 miles of Criswell.
A plug is fine for an emergency, but the tire should be taken and properly plug/patched when you can get around to it.
I had a puncture on a long weekend trip ( 600 miles), and the shop was not able to dismount the tire, so it was just plugged. I completed the trip, and then took it to my tire guys later in the week where they installed a patch/ plug. Drove another 30,000 miles on that tire.
