Whipple in cooler temps. Any tires that can handle roll racing?

[2019GT]

65F today on Michelin AS4s (275/40/19) and 3rd gear began to go sideways pulling from about 55mph. No feathering the throttle, and I should mention I shut AdvanceTrac completely off. Dyno around 700WHP

I know with AdvanceTrac on I can track straight from 3rd gear on these tires.

I was considering to TRY the AS4s with a 275/35/19 and 325/30/19 stagger, same sizes I used for my summer wheels which I loved the feel of. Gave the car more of an understeer bias and car tracked super straight on roll races. Only thing is, 325/30/19 only comes in a ZP (run flat) which I heard SUCKS

But maybe I need to just tone it down in cooler temps and take it a little easier. I'll probably have to end up leaving stability control on too.

Figured I'd see if anybody had any luck doing hard rolls in cool temps though ...

I really like nitto 555r2. I’ve had them for like 2 years. Really good tire. There’s obviously a decrease in wet traction, I keep it to about 40-45 in water just to be safe. Definitely nice to be able to enjoy the car without needing a drag pack.

Sorry, I should mention I'll be seeing temperatures in the 10s. Not to say I'd consider doing pulls when it's *that* cold ... but as low as 30F would be nice to find something that can pull from 60MPH.

I'm sure those tires are great otherwise, they compete with the R888Rs I'm pretty sure

A 325/30/19 tire is 1” smaller diameter than a 275/40/19. It will look small in the large wheel well. Plus, you’ll be increasing your effective gearing, offsetting some of the gains of going to the wider tire. 315/35 would match the original tire diameter and provide better traction than a 325/30 due to the longer contact patch (front to back) and less gearing. 325/35 would be even better but I’m not sure how common either of those sizes are. 30 profile should really only be used on a 20” wheel.

Yeah I'm running on 19s and the Michelins are a bit limited in aspect ratio. I would have put 275/35 up front to match the 325/30. I'm lowered an inch so these sizes don't look too bad (i ran 275/35/19 + 325/30/19 this summer), but I do hear your point about changing the effective gearing with a smaller diameter.

If I went 20" rims, I could do 275/40/20 and 315/35/20, but I'm not sure if a 28.7" tire would fit with a 1" drop.

I'm more concerned that I go spend all this money on new rims and tires just to find I still can't put the power down for a 60 roll in 30F lol.

Think the AS4 in 275/40 and 315/35 on 20x10 / 20x11 will let me put the power down as it gets colder? 4th gear at 65F with AT off wasn't a problem with 275/40/19.

Michelin doesn’t make a 325/35/20 pilot sport all season 4. But If it’ll fit, they make 315/35/20 and 285/35/20 for the front. Michelin makes those sizes. Continental extreme contact DWS06+ is also a great tire and available in 315/35/20 and 275/35/20. I think those 315/35 will put the power down better than 275/40/19. If those taller tires won’t fit you could go with ZL1 sizes in the Continental: 285/30/20 and 305/30/20.

Screw it I'm going to try it out and see how it goes. If it doesn't help, at least the car will look more badass with the beefy tires bulging out lol. And my wheel well will be completely filled.

But, fingers crossed I'll be able to do 3rd gear pulls after this

Ha, yeah. I mean, it’s going to be hard to put that much power down without warm, fat sticky summer tires, but if you roll into it that would help. My ZL1 A10 traps ~130 mph in the 1/4 and if the road isn’t dusty I can roll into it in 3rd and put the power down pretty well with the DWS06+. The high performance all seasons are night and day better in cold weather than any high performance summer tire. Sometimes if I roll into it just right I can put most of the power in 2nd gear down; but it’s a pretty slow/steady roll in on clean asphalt. That said, the ZL1 has 2.85:1 rear diff and the same gear ratios as the Ford A10 so less overall torque multiplication. I think the base A10 GT is 3.15:1. But the LT4 makes more torque by nature of its pushrod/larger displacement so it’s probably similar from a power down perspective.

Anyway; good luck with it. 315/35 Can’t be worse than the 275/40, right?

You have to keep in mind, in the summer on PS4S I can slam the throttle in 3rd gear and be fully confident I won't go sideways. I did it more times than I remember this summer and that's with stability off. So I might be a bit unrealistic trying to replicate that in the winter.

Based on what you're saying though, I may get close! And if anything, I probably just leave stability control on and then I can safely have fun even if I get some power robbed from me lol. Trying to not "need" stability control like that though.

FYI. This morning on my way to the gym I nailed it in 3rd gear at 3k rpm (below the LT4 torque peak), and spun the tires and traction control kicked in. So don’t expect a miracle! They can definitely handle a fast roll in though; just gotta transfer some weight to the rear before nailing it. Or a “dual stage” throttle application: straight to 1/2 throttle to transfer weight; then almost immediately (a few tenths later) to full throttle. Gotta get to full throttle after the car has squatted, don’t want to wait too long and the weight starts to shift forward again.

Though like I said; when I had summer tires the grip was lacking until the tires were warm. On a cold day I’d spin em at 1/4 throttle in 5th if the tires were still very cold.

Damn! Sounds like you were going on the slower side given 3k revs in 3rd, assuming you have a 10 speed too but not too sure how the ZL1s come. If I'm right, then curious how you'd do launching from closer to 60.

I'm definitely going into this open minded Will take your tips and play around after I'm on the new wheels.

Not sure what power you're making in the ZL1 but I know those things come blown and have torque too, so might explain why you can't stab 3rd cold in summer but I can. The 5.0 isn't that wild til the revs jump so I probably got that in my favor too.

I think the traction is heavily influenced by street conditions (age, dustiness, etc.).

Last winter while doing some test splits in cold weather I spun at 55 mph in 3rd (A10 trans) if I nailed it, but the asphalt was older. I’ve never dyno’d the car but 129-131 mph trap speeds would be around 600 whp. And similar torque since the LT4 generally makes about as much wheel torque as whp.

This morning it was 65 F and I went WOT very quickly in 3rd at 55 and didn’t spin. But it was relatively new asphalt, which is grippier than old asphalt. I will say it felt really fast after not getting on it in cool air for a while (summertime temps). The cold air effect is real.

You need a dedicated drag radial, IMHO

So it's currently 72 in California an I'm on a MT ET ss. I can tuen off traction control. I can break em free from 55 to 90.

My point is, your not gonna find a tire that will comply to your demand here
