will 255/50R19 work on 19" GEMINI WHEELS for model Y?

[coolmanfever]

hello all,

I have a spare set of X-Ice Snow tires but they are little bit bigger.
X-Ice Snow - 255/50R19 XL 107H

will 255/50R19 tires work on 19" GEMINI WHEELS for model Y?

Judging by my calculations it should fit. No issues in the rear. The front is the problem but i think it should fit. Worse case just take it to a tire shop and have them test fit it. Worse case you’ll be down about $30

I just put Pirelli Scorpion A/S Plus 3, 255/50 x 19 on my 2021 MYLR, Gemini wheels. No fitment issues.

(No comment on ride comfort/range until I've put a few hundred miles on them. Of COURSE, 11/32" tread rubber is softer than 5/32" Michelin PilotSport A/S 4 high performance tire rubber!)

good to know

These are SCORPIONs, not P7, which don't exist in the 255/50 x 19.

The load rating is 107h, vs. 104h.

Update: 2021 MYLR, 51 k miles.
1000 mile Pirelli Scorpion A/S Plus 3 255/50 X 19. Vehicle is at 51k miles, with Mountain Pass Performance Comfort Coilovers installed at around 10k miles.

Here are a few things to consider:

1) Aspect ratio 50 vs. 45: This size tire absorbs road imperfections much better than 255/45 X 19 tires. MUCH better.
2) Load rating 107 vs. 104: I thought the slightly higher load rating would have a stiffer sidewall, thus negating the change in aspect ratio.
3) These tires start at 11/32" tread vs. 10/32 and 9/32 (IIRC) for the ContiPros and the Michelin PilotSport A/s 4s.

However, because of the increased load rating, I can safely drop PSI to 36psi, vs. Tesla's recommended 42 psi.

So far, I like the ride of these tires MUCH more than the OEM-size Conti ProContact (30k miles) or the Michelin Pilot Sport A/S 4s (20k miles.), both requiring 42psi.

I don't push the handling characteristics very often. The tires seem to "float" more, which makes sense, but the car feels nicely planted at all times.

I'm baffled by the efficiency, because it seems to have IMPROVED over the OEM sized tires. This is probably because of perfect ambient temps of 50-70f, with minimal load on the HVAC.

(I might cross-post this entry in other tire comparison threads. I hope the moderator doesn't mind.)

Good info. Did you try the new tires at 42psi? If so, what were they like?

Technically, to match the 104 load rating, the Toyo charts show that you would need just over 38psi on the 107XL tire to match the 42psi rating on a 104XL.

MattM24: Interesting. I read a chart from another car company, and it showed 1907lb. capacity at 36PSI for 107XL tires, which, of course, is for a fully loaded vehicle.

For the record, I drive solo 98% of the time.

Yes, I tried 42psi. The ride improved significantly when I dropped to 40, then 38, then 36PSI.

This chart also shows 1907 lbs for 36psi on a 107XL.
The 104XL shows 1984 lbs at 42 psi, which is what I was using as the direct comparison.

Individual use cases will vary of course. YMMV, right?

It’s also worth noting that for non-LT rated tires on SUVs, the article states that the tires needs to be able to handle 10% more than their axle rating. With the axle rating for ~3,600 lbs, that’s 1,800 a tire plus 10% or 1,980 lbs. Hence the 104Xl at 42 psi rating.
