I would stick to a stock tire size on that wheel.
Edit: I see you have a 2015. 245/40/18 is a good size for an 8.5" wheel (stock size on 2018 premium)

That's correct, wouldn't recommend that wide of a tire on 8.5" wheel.

Those are the wrong bolt pattern. You need 5x114.3.

My setup is best setup.
19x9.0 +50mm 275/30R19 stock sus no rub no fender rolled.

if you can, grab O.Z. ULTRALEGGERA 18x9.0 +55mm with 5mm spacer and run 275/35R18

Cheers,

I notice a lot of guys are moving to 9.5 width rims and moving up to 255 or 265 tires. I myself am also considering doing this. I'm curious if those that are moving up in tire size are also correcting their speedometers or just living with the error?

What I'm finding kind of tricky is the vast majority of wheels, including all the ones I really like, seem to come in 8.5 and 9.5 widths, not 9.0. What I've noticed is my stock setup(245/40R18) is exactly 1 mph slower than GPS(Speedo shows 80mph/GPS shows 81mph). Thus, if my calculations are correct, a 255/40R18 would by slightly larger diameter and read almost exactly almost exactly 1mph faster than the 245s. So it would just correct the built in error I have from the factory.

Issue for me, and this is just me, I'm not knocking it, I'm not a fan of the stretched look. So on a 9.5 in rim, I'm guessing a 265 would fit just right. If I go 265/35 A/R my wheel diameter is smaller than the 245/40 and thus I introduce more error(Speedo 80/GPS 82.26). If I go 265/40 I over correct(speedo 80/GPS 79) and then my tire is .6 in taller. I haven't heard of many running this setup. But I have to assume rubbing becomes an issue unless you introduce camber(not interested).

So this is a long winded way to see if anyone else grappled with this when making your decision? Did you have a way to correct your Speedo? Or do you just live with it and it doesn't bother you.

Thanks

I just live with it; I'm currently on 18x9.5 265/35 and it's off by ~1 mph. I couldn't tell the difference in 1 mph and a cop wouldn't pull me over for 1 mph over so it's whatever

Over the years I've owned several cars whose speedometers were known to be off, either from the get-go or after tire sizes or axle gears were changed. And the speedometers in at least two of those cars were inop for extended periods of time. I remember driving one of those on a longer trip and keeping a rough track on speed by converting the number of seconds between mile markers to mph, and driving by converting the tach reading to mph in another.

That's kind of a roundabout way of saying I don't worry much about speedometer accuracy. Don't look at the thing all that often anyway.

I will admit to having eventually corrected speedometers - but only when it was convenient to do so. I didn't even consider trying to correct the Mustang's speedometer when I went to tires a whole inch or more shorter than the OE sizes. I may not even bother when I get an axle gear swap finished (it's not a very big ratio change, but it will exaggerate however much error it's at now). At least not right away.

Care to share some info?

Wheel size, tire size, suspension mods?

Edit: Scrolled back a little and found your specs. Looks good.

^^ Pretty sure he's still on stock suspension.

His wheel setup - 18x8.5 +44 offset rubber on the rims will be 245/40/18

Wheels are
SSR GTX 01- 18x8.5 Offset 44
Rubber: 245/40/18

Coilovers have been ordered looking to lower the car 20mm all round so the wheels can tuck in nicely.

Overall I知 very happy with the end result

Do you happen to have any pictures from the front that show how far in the wheels are from the fender? Debating going with a similar spec wheel.

They will be 11mm (1cm) out from stock. Pretty conservative setup. Maybe you can measure off your car to get a better idea?
