more picsIs anyone running this size tire 255/35/20 over the stock 235/35/20. I am looking at putting on Michelin pilot sport 4s.I am sure the tires will save the rims from curb rash but will take a hit on mileage / efficiency. Are 255's too wide and is clearance a known issue?
And does anyone have experience running run-flat tires?
Sweet, looking forward to your update. I hope it works out for you! I have seen a few posts here of people running 255/40 and it is tight but it fits. Might experience some rubbing at the beginning of the tire's life until the tread wears down a bit.I have a set of 19x9.5 et34 wrapped in Conti DWS06 255/40's being mounted next week. Will report if I have any rubbing if anyone wants to wait and find out. I am in the same exact boat as @SirLaz. Dont want to sacrifice too much efficiency but want the extra sidewall protection.
Keep in mind, most people seeing rubbing are running Michelin PS4S which notoriously run larger than the averageSweet, looking forward to your update. I hope it works out for you!

I am in between going 255/35 and 265/35 at the moment. Would like the smaller tread width of the 255 but sacrificing some sidewall and also lowering the overall diameter of the wheel by 0.5". Running a 265/35 would only be 0.2" smaller than the OEM diameter and from what I have gathered it is best to stay as close to the OEM diameter as possible.
Good point. The DWS06 plus are significantly smaller in terms of width than the PS4S, so it will be interesting to see how the fit is. Crazy because I am on the OEM 235/35/20 PS4S right now and going to a 255/35/19 DWS06 plus actually has a smaller tread width, so in theory should have better range but not sure if its work exactly like that.Keep in mind, most people seeing rubbing are running Michelin PS4S which notoriously run larger than the average
Ouch yea that is quite the hit on efficiency. I am coming from the OEM 20" P wheels and PS4s (about 295 wh/mi lifetime with 10k miles) so I hoping for a similar efficiency with this new setup. A different tire might honestly make the road noise and efficiency better, those A/S3+ are pretty heavy as well as wide. You could drop down to a 255/35 or even 245/40 if you don't mind the stretch. Might save some headache of trying to sell your setup and get new. I've heard good things about the DWS06 plus and may also suggest looking into the Falken FK510 if you are fine with a budget summer tire. Both have significantly smaller tread width which from what I have gathered makes a big difference with efficiency as well as how much the setup affects the aerodynamics of the car so limiting the poke would yield more range I assume.
But I feel you on getting a smaller wheel, I ideally wanted 19x9 so I could fit a 245/40 without stretch but was impatient and didn't want to wait for them to get back in stock. There are also plenty of 19x8.5 or 18x8.5 options that you can use with the OEM size tires which shouldn't impact range, might actually improve it if you have significant enough weight reduction.
I will post my setup once I get it squared away!
I’m running 255/35R20 Michelin 4S zero issues. I will let you know because I’m going to test fit a 255/40R20 tomorrow.Really insightful replies here, thanks guy.
Looking for some feedback. I just picked up some 19x9.5 Titan 7 T-S5s and am debating on what size tire to put on.
I'm between 265/35, 255/40 and 255/35 right now. Looking to get optimal comfort and least amount of range reduction as possible. Anyone have an idea what the difference in range impact is between the 255 and 265 tires? I don't mind running the wider tire if range impact is around 5% difference. I am coming from the OEM 2020 20" performance wheels with OEM PS4s.
I am leaning towards 255/40 at the moment since this will give me more sidewall for protection and comfort, but worried that these will rub. I am at stock height.
Any experience would be helpful, thanks!
Thoughts on wheel locks, especially with 129 ft/lbs torque requirement?Hey everyone I own a 2021 Tesla Model 3 and I manage a Discount Tire store (16 years Experience)
That’s definitely a good question! The best that I have seen is Gorilla Automotive locks. Not the locks with a hallowed out center because those will strip out eventually!Thoughts on wheel locks, especially with 129 ft/lbs torque requirement?
‘20 M3Ps come with 20”x8.5” rims. So, no they don’t look stretched. ‘21s come with 20”x9,” IIRC.OP: My 2021 came with 235/35/20 PZeros, and they look stretched. How were your Michelins (I am assuming PS4S)? Were the side walls more square, or did they also look stretched?
I saw somewhere that the 2021 rims are 9" also, but now I can't find where I saw that. Making things even more confusing, my 2021 owners manual says the wheels are 8.5" wide.‘20 M3Ps come with 20”x8.5” rims. So, no they don’t look stretched. ‘21s come with 20”x9,” IIRC.
Gotta love the interwebs.I saw somewhere that the 2021 rims are 9" also, but now I can't find where I saw that. Making things even more confusing, my 2021 owners manual says the wheels are 8.5" wide.
Indeed, lol. Thanks, man.
