New Tires for GT

[Jeffgorwitz]

I have a 2022 MME GT. My rubber is already wearing down with 10K miles. We all know that the stance of the Mustang on the factory tires isn't the most impressive. I have 20" rims and would like to put wider tires on. I have a feeling that will affect my range—any suggestions or experience from other owners on wide I can go without sacrificing too much range?

You asked a loaded question. You will now get a dozen or so inputs on which tire is best for the car. There are several members that have installed several tire brands and can provide input. Mark (@markboris) is one of those members that can probably point you to a few of his posts and provide great advice.

I think you will want to add some clarity beyond wanting to keep your mileage close to the current range and wanting wider tires. Do you want more performance? Do want to keep or sacrifice the noise? Do want EV specific tires or any tire? Do you want all season tires or summer tires? I sure I missed a few more questions but other can jump in.

Here is one of many threads on the subject.

I live in South Florida so I need a tire that works well in the rain, but I also want a tire that makes the car look a little "Beffier" but don't want to sacrifice too much range. RIght now, I get 234 at 90%.

Quiet ride, but good for wet roads and hot as f$*)_ temps

If you are going to retain the use of the stock wheels, that will be the best thing for not affecting your range. You can go up 10mm on tire cross-section to a 255 for a little more performance safely on the stock wheels. Just be aware that any time you increase tire width without also increasing rim width you will have to decrease tire pressure in order to maintain a good contact patch.This will affect your range, but not as much as changing from a wheel with good aero to a wheel with poor aero. And the problem with aftermarket wheels is that the vast majority of them have much worse aero performance than the stock wheels. ?‍?

William and Steve are right on the money. You can only go up one size to 255/45/20 tires and not sure that will give you the "beefy" look you are going for but they are just about 1/2" wider than the stock tires you have now. There are also many more types of tires available and many members here are running that size. I would look at the thread Steve suggested especially this post #34 . When you have more questions, come back and we will answer them. ?

I’ve been running with the wider tires for a while now. Do they cause rubbing on full lock turns? If I do a full or almost full lock, I feel like I’m hearing rubbing but can’t find any evidence of rubbing and it only seems to have started in the last few months and only when going left. Could it be something else? I feel the dealer will just instantly point to the wider tires and do nothing. Maybe time for an alignment at 20k miles that can fix it?

This is the first I’ve heard of 255 tires on OEM wheels causing an issue. There is so much room with the stock setup that going one size larger should not be an issue. I’m thinking it may be something else. I’ve run 275/40’s up front which are 1 1/4” wider and they get close to the inner fender. Of course it can depend on the tire as some have rounded protruding sidewalls and others are square/flat. Even if you have a slight rub at full lock should not be an issue.

I live in Seattle so I know a thing or two about rain as well! LOL
I really love the Pirelli Scorpion Verde All Season tires, they eat standing water on the roadways. Most impressive tire I have had for lots of rain. I have them on all my cars.

These are awesome suggestions, and your showcase is gorgeous!

My question is running a 255/40R20 vs 255/45, and how that’ll impact ride quality. Ride quality is so bad, borderline unacceptable imo on the stock Pirellis. Pressures are at and even 1 or 2 below spec, so I’m not sure if I’m missing something.

On the other hand I’m really excited about the Hankook Ion Evo (summer) hitting shelves as we speak. By all metrics theyre handily beating both the Pilot Sport EV and to a lesser extent the PS5 (which was my first choice).

My question is, why would you want to run 255/40's? Ride quality on the 255/45's will be a bit better because of the taller sidewall and a little less noisy. Not to mention the 255/40's are a full inch shorter in height.

Looks like you want to stick with summer performance tires and my first choice is always the PS4's (or 5's). The summer Hankook's are EV tires so I'm sure they will be quieter and give you a bit more range than the Michelin's but I cannot see anything beating the Michelins for all out performance. When I start seeing Hankook's as OEM tires on super cars and many other high performance cars, then I will take note of their performance but right now, that territory mostly belongs to Michelin and Pirelli.

On the 255/40/20 vs 255/45/20, I would highly recommend the 255/45/20 105xl so many potholes with the smaller sidewall you are much more likely to damage your rims. My car has Vredestein Ultrac Vorti UHP Summers 255/45/20 105xl they are great but not LRR or EV tuned. One huge advantage is with the higher load rating you can lower the tire pressure and that makes the car more comfortable to drive. with 105 load range, the pressure should be lowered to 36psi and because of the higher load range the tires will support the same weight.

In a world where all else is equal I think the thinner sidewalls look better. If the decrease in sidewall is counteracted by lower pressures/wider tire and a better quality tire I’d be ok with it.

On the performance what do you think of the review I linked? The PS4S isn’t tested but the PS5 which is only a little less hardcore still gets outperformed when put on an EV. It’ll be interesting to see if they get picked up by major brands or not, all I know is the refreshed Model 3 is using them over the PSEV. To be honest I just haven’t been impressed with any a single aspect of the P Zeros so I’m going back to Michelin or really anything else.

I also think a thinner sidewall looks better however it seemed you were after a more comfortable ride. The taller sidewall would definitely get you that along with what Brian mentioned, less probability of a damaged wheel if the roads you drive on aren't all that great. This is an SUV, not a sports car. I wouldn't put a short sidewall tire on the Mach-E just like I would never put a tall sidewall tire on my GT500. While not my recommendation, nor Brian's, it's not like you can't run 255/40's.

About the review you linked, the Hankook's were very impressive against the Michelin's. I would like to see more tests by others but they look very promising. The PS4S's are very hardcore and think they would stand up well against the Hankook's if not beat them. I have a staggered setup and the Hankook iON EVO's (performance or all seasons) are available in very limited sizes, none of which will fit my setup so I've never been able to test them but would sure like to.

As far as Pirelli P Zero's, they are not up to the performance of the PS4S's but they do run a close second. The one thing they have going for them is they are smoother and quieter than the Michelin's. I know you're NOT interested in a high performance all season tire but Pirelli has better options than Michelin in that area for EV's. Right now I'm running the Pirelli P Zero All Season Star BMW tires. They are EV tuned specifically for BMW's i7 EV and out of the ties I've tested, they are the smoothest riding, quietest with the highest range. The lower rolling resistance definitely shows up in the added range I'm getting. The performance is no where near the PS4S's for sure but I wanted to spend a year with these tires and I'm just about there. When winter is over, might throw the PS4S's back on. I'm very interested in the new Pirelli P Zero E tires but we won't see those in sizes I'm interested in until next year, if at all.
