I haven’t driven on them yet, but listening closely under the car while turning the wheel, it did not rub.

285/35R19 on 19x11s.

Can’t lower it to the ground until my extended studs arrive Monday, but a quick test fit with 13mm spacers is tight but has no rubbing. Going to stick with 12mm spacers and shave the upright a hair (and move the zip tie) to ensure fitment. I concur (and suspected) 10mm wouldn’t work without...

Super helpful comparison! Making me rethink my daily 285s…. (Very Slightly :P ).

Interesting. I don’t think I’d ever heard of water injection on brakes! How do you avoid warping or, just as importantly, inadvertently dropping water onto the track? Fine mist only at high speeds?

My 370x34 front rotors are pretty worn and will probably need replacing. Would UP’s 394mm kit be a worthwhile upgrade, compared to, say aggressive ducting? (Note: I am still on stock rear M3P brakes with aftermarket pads).

Can you code the Partybox to override or disable this safety feature???

I grew up on dirt bikes, mountain bikes, and off road 4WDs and am very used to feathering brake and throttle to manage traction and rotation. So, left foot braking itself is very intuitive for me. Unfortunately, the way Tesla couples throttle reduction with brake application—and especially...

That makes sense. Unfortunately, I experimented for a couple months with left-foot braking, and never got over the inability to blend brake pedal application and forward throttle. Even just bumping the pedal accidentally seems to result in a ~1/2 second delay in throttle onset, which can really...

Interesting. I do suppose 14 turns in 1.3 miles is pretty tight without a lot of time to cool the brakes between turns. How did you like driving without the regen? I’ve heard a few folks now report they performed better with Regen low / off.

Okay that’s what I was seeing (especially because your calipers say APRacing on them :P ). The calipers are slated for 360-390mm x 32-36mm discs, which would put them about it even with most aftermarket kits. What track did you say this was?

Staying in a house without a real garage and trying to hide my car from these Midwest storms :P .

Can you confirm what brakes you are running? You mentioned 355mm discs before, but your pictured calipers don’t seem stock unless I’m crazy…

I saw some bluing… on a road course 😅 . Can’t imagine the wild autocross runs you are doing to get enough speed to do that! Hell, even with my sparky Powerstop Track Day pads my rotors don’t get that hot :P .

Helper bags should technically fit in the Model 3. However, honestly a mild spacer lift might be a more practical option for you. https://www.mountainpassperformance.com/product/mpp-1-75-suspension-lift-kit-tesla-model-3-y/ I am lowered, and during my last move I definitely scraped a bit...

In following the common recommendation of keeping tread width 0-0.5” less than wheel width, I bought the wheel specifically for the 285/35R19 RE-71RS’ 10.5” tread width. Of the options available in 295/3x/19 (i.e. the A052) I don’t think any would outperform a 285 RE71RS anyways (which isn’t...

Sounds like offsets are quite close, but my first thought was caliper clearance. Does the Highland use the same calipers as the previous generation?

How large / fast is your track? My tighter 1.7-mile circuit only used about 1.5% per lap in Chill Mode. And, pointedly, I’d run a slower lap or two to save battery. Additional lateral motion is probably the most efficient way to warm up the tires beyond just running the course.

(Just following up in this thread as well. With my Girodisc rotors I am only expecting to need about a +28 to fit the planned 285s. I willl be running extended studs and probably 12mm spacers.

I suppose I’ll find out! Of note, my Girodiscs add about 5mm, and I’m only going 285s, which buys back 10mm total. That’s where I figure a +28ish should be close!

Ended up ordering the 19x11+40 Hypergrams to use with extended studs and something like 10-12mm spacers. Thanks!

Just ordered some 19x11+40 Hypergrams…

Great runs!! Sucks about the track mode telemetry :( .

I exclusively do “waterless” washes with those “quick-wash” type spray-bottle products and a few microfiber towels. I do it maybe 4 or 5 days a week to keep it clean and shiny. If the car is really dirty (I.e. driving through a rain after a multi-week dry spell), I’ll soak one or two microfiber...

Hey guys I’m new here. So, what tires should I put on my car?

A drink for each of you then… you’ll need the confidence :P .

Somebody get this man a drink!

Yeah, a 285 27” tire will be a bit more challenging in the fitment, but the main benefits are both a bit more tread width and a bit more total surface area for track days or even the hotter AutoX days! Thanks for the insight!

I am kind of back and forth between the 275/35R19 and 285/35R19 RE71RS. For the latter, I am looking at the much more limited 11” wheel options that are all generally heavier or more expensive than something like the Konig 19x10.5s. If you were hypothetically stuck with a 10.5” wheel, would you...

Just to be clear, your understanding is still that 295s and 305s would be generally faster—even if [by a tenth]—on a 10.5” wheel than a 275? @MasterC17 Given your experiences over the last few years, and your own comments on the subject, I’m hopeful you can find the time—and desire—to chime...

I remember being annoyed that Boosted LRs were “almost” as fast as Ps above about 60-70mph. Then I realized the parlor trick is in the 0-80 range, and above that quickly approaches major consequences. I’m absolutely okay with some clever mods to mostly improve 0-60, with only moderate gains in...

Also, @dsgerbc , you mentioned camber and other adjustments. It’s certainly possible that a wider tire on the same wheel does require either a camber or pressure tweak to maintain the inherent performance gains of that wider tire! So, indeed, there are missing data in our quest for “the best...

That’s a fair point! I am currently looking at my own acknowledged bias against the “…well we’ve always done it this way…” philosophy. You might be on to something… maybe “less than ideal” is still “better than a 275” for us?

Sorry for the confusion. I was just acknowledging that if someone was seeing a lot of edge rollover because their wheels weren’t wide enough to properly support the tire at idea pressures, they might try to compensate with higher pressures which would unintentionally negate the benefits of the...

The article I referenced actually was the 2022 test, which indeed showed the 225s were fastest with the available rim width. As mentioned, they assessed the 245 would have been fastest if they could have mounted it on a 17x10 wheel on the test vehicles. That is what I highlighted with the...

Thanks for the notes! I certainly have no question that overall, wider is better for ultimate grip! Still, this Tire Rack test, even if less than perfect (but still better than 99% of internet anecdotes), is far from the only example asserting that best traction requires a sufficiently-wide...

I absolutely understand this reality, never contradicted it, and am not sure why this is the singular focus of all the responses… Anyone have actual inputs on my bolded question above?

(Tracking! I didn’t specifically say it, but yes my assumption is one runs proportionally-lower pressures with the wider tires. I alluded to it in the earlier comments that if one runs a wider tire, but has to bump up pressures to compensate for an under-supported sidewall (assuming appropriate...

Oops. I meant total TTSA per pound! The model 3 is about 40-45% heavier, inherently requiring more rubber in the ground to avoid overwhelming the tires. Separately, the greater power-to-weight of the Model 3 puts even more stress on the rubber, potentially justifying even more TTSA without...

We have all seen the Tire Rack width test (discussed in this thread). @MasterC17 ’s observations posted in his 200tw tire assessment (linked below) corroborated Tire Rack’s, where he assessed a 275 was best for a 10.5 and, as an example, a 255 would likely perform better in a 9.5 than a 275...

I, too, quickly found the extra 90-120 minutes a month tweaking alignments back and forth was not worth the modest (~20%…?) loss in tire life running 3+ degrees of front camber (and ~2.5 out back). In 100k miles I might have to buy 5 sets instead of 4, but in that same time I’d also spend dozens...

Btw, is this a 315/35R18 (26.7”) or 315/30R18 (25.4”)? And confirm you mean the 18x11+40 wheels, using 15mm front spacers?

This is what a Marketing Department is for. There is some perfect price where the die-hard top-of-the-line buyers will feel good paying (I.e. those who would pay $100k for an M3Comp over a 60k 335), but also low enough that the volume justifies the R&D. For the LR vs P, they basically...

Oh, I’m tracking the real-world numbers very wildly, but was just looking at it through the lens of advertised numbers as one means to determine if it actually has ~50 more Hp!

Isn’t the current M3P officially advertised at something like 450hp?

Honestly I feel like most of the optimism about its specs come from our shared desire to continue championing EVs. I find myself rooting for Elon’s underdog vision than EVs can be more than simply quirky around-town vehicles (but even drag kings and cone crushers). I was cross-shopping M3s...

The huge Tesla devaluations were a perfect storm of global supply chain issues followed by a massive ramp of of production capacity AND a deliberate sacrifice of per-vehicle profit to increase volume as other competitors came on line. Other new vehicles will experience part of that after...

There was a time Dodge sold an SRT-10 Ram pickup truck where the highlight was the “Viper’s V10!” It was barely faster than the Dodge Neon SRT-4, but they catered to very different markets! Even now, a BMW X5M, M7, and M3 are all “M” cars, but only have a modest overlap in shoppers. I think...
