Traction issues (AGAIN) after storing tires indoors

[2019GT]

I made a previous post about winter tires for 700whp setup, will update with a link. ( https://www.mustang6g.com/forums/th...any-tires-that-can-handle-roll-racing.192091/ ) In that thread, I reported about going to Michelin AS4 in 315/35/20 and I could hook 3rd gear with AdvanceTrac OFF even in 30 degree weather.

I just put those AS4s back on as we are hitting 40s at night, and I can no longer hold 3rd gear anymore.

Temps are mid 60s, tires all inflated to 30psi (as they were before when all was well, but I checked and made sure)

Tires were stored INDOORS, mounted on rims, inflated about 30psi, stacked on top of eachother, each wheel in a big plastic bag and duct taped closed, and then one big plastic bag wrapping all 4 wheels.

I lightly cleaned each wheel and tire before storing them.

They were only stored from mid May to about mid October.

I don't get what I'm doing wrong here. If the tires were just fine immediately before putting them into storage, why am I running into issues now?

The only thing that has changed is I swapped from Lund to Wengerd tune (we slightly bumped MBT so timing comes on quicker), or potentially something about it being autumn has the roads being less grippy. But I don't want to get farfetched here.

I know I can just buy 2 new rear tires and all will be well, but I'm about to store my PS4S and don't feel like running into this issue again!

Also should point out that when I pulled the tires out of storage they did not feel dried out whatsoever. Not to say they felt wet, just not dried out. Like healthy rubber i guess I'd say.

I would say the tune is your answer. Wengerd is no joke, when I had my 22 GT (not boosted BTW) the difference even NA was pretty dramatic when I got his tune after my intake and headers... That said, I had the PS All Seasons on mine for a while on the PP wheels (275 40 19) and they hooked really well, I drove on Christmas eve 2022 in single digits and matted the throttle from a dig and had zero wheel spin. Dry pavement, stock car though...

Yeah these tires are very impressive. Sometimes I wish I was stock again just so I wouldn't have these traction issues!

Well, I guess the next thing I could try (sadly) is to load back my old Lund tune and see if I still have traction issues. I have a less aggressive Wengerd tune as well but I might as well go back to the last known state completely and reverify. That's the only way I'll know for sure if the tune is the reason.

Hey, you know the Carol Shelby quote. There is no such thing as too much power, just not enough traction . I would rather feather the throttle and have all the beans than to neuter it... And the All season 4 is the best all season tire out there... Unless you can fit 325's maybe...

How much have you actually drove on them ? You have to get the top layer worn off but that should happen quick, also road temperature will have an impact on traction.

(Also tires should be stored deflated but it doesn't really matter much, your tires should be fine).

That is very true! I don't know how the car will react at redline when all the power is there and that scares me if I'm being quite honest. I've tested these tires in 2nd gear and was borderline holding traction all the way up until near redline when I could tell it probably wasn't going to hold and so I let off. I like consistency what can I say? Haha

I probably put about 50 miles on them since reinstalling them. And I've also spun the rears out quite a bit so that top layer should have been off already haha.

Even on rims you would completely deflate them, or just partially?

UPDATE -- i reloaded the Lund tune and did almost 10 pulls from 3rd gear because I am a mad scientist. DEAD HOOKED.

Same exact road, same day, only about an hour or two apart.

Car also feels slower now

This definitively proves the Wengerd tune is putting down more power at least on the hit, and it also proves the PS4S 100% has more dry grip than the AS4 (obvious i know)

Next up, I need to test Wengerd's revision where MBT and knock strategy should be similar to the Lund tune, that is to say less aggressive.

I told ya..... Wengerd FTW Maybe keep the spicy tune for the summer months and run the less spicy in cold weather...

I have even better news ... I just tested Wengerd's less aggressive tune with the standard timing ramp up and knock strategy ... dead hook!

I think I am feeling mild tramlining so I have to get used to that again. It's always a shocker to me switching tires between seasons

Anyway, yes you were 1000% correct!

Hopefully this tune will hook in 30s too but if not I can always just use the Lund tune or maybe ask Wengerd if he'll make me a blander tune haha.

PS even Wengerd's standard tune is still faster than Lund's. I can feel it

But all tunes are Lund tunes............Right.

(sarcasm)

Be nice if you could do a back to back drag strip or draggy run. That would shut up all the Lund D*&k suckers

You know, this is some stupid funny advertising for Wengerd. Imagine being so bumblef*cked why your tires can't grip anymore, turns out the root cause was swapping from Lund to Wengerd

This is actually a cool idea to test them back to back!

Would it be a more fair comparison to use Wengerd's tamer tune or the more aggressive one? He custom tweaked it per my request so that's not what all of his customers would get.

Up to you but I'd do the more aggressive one. If he can do it for you he can do it for all.

 

[robvas]

Does either tunes affect traction control? Even if there is 20hp between the tunes I don't see one dead hooking and one spinning...

Yea thats fine, I might try the more aggressive one again just to be thorough in verifying my tires didn't somehow get grippier after all this testing. But if I still can't grip, then that'll have to wait til next year
