Default Re: A Focus-friendly tire diameter chart

Ok I found 2 more rims, one that is 17 x 8 that has a back spacing of 12mm and...

another 17 x 9 BUT with 26mm backspacing....

Would it be possible to get either of these to fit?

It is just that I'm looking to put the maximum contact patch to the ground that is SANELY possible.

Does ford change the calibration on the speedo depending on what size they install? Or is 'close enough' good enough?

My car came with 195/60/15s and the ECU calibration was for 861 revolutions per mile - if that helps.

The correct overall diameter of wheel/tire combination is calculated as follows:

e.g. 205/50-16 is 205 mm. tire width with an aspect ratio of 50% of the tire width or 102.5 mm. multiplied by 2, thus resulting in 205 mm. and then added to the 16" diameter in mm. which is 406.4, giving you a total overall diameter of of 611.4 mm. or 24.07"

[[185*65%]*2] + [14*25.4] >> [120.25*2] + 355.6 >> 240.5 + 355.6 = 596.1 mm. -or- 23.468 in.
[[195*60%]*2] + [15*25.4] >> [117.0*2] + 381.0 >> 234 + 381 = 615.0 mm. -or- 24.212 in.
[[205*50%]*2] + [16*25.4] >> [102.5*2] + 406.4 >> 205 + 406.4 = 611.4 mm. -or- 24.071 in.
[[215*45%]*2] + [17*25.4] >> [96.75*2] + 431.8 >> 193.5 + 431.8 = 625.3 mm. -or- 24.618 in.

Has anyone used a 225-40-18 on their Focus? The basic specs seem like they would fit well but I want to be sure first before ordering.

Thanks.

Default A Focus-friendly tire diameter chart

I know it is probably a competitor site but www.7thgencivic.com has a really good tire calculator on their site. (My dad has a 2002 Si) You give the original size and then the size you want to buy... and it will compare diameter, revs per mile, Circumference, radius, and sidewall height, and what % your Speedo is too slow or fast. It also has a visual to give you somewhat of idea how wider or taller.... very helpful

Is there a difference in speedometer calibration between SVT and other Foci ? The OEM tire diameters are a little different.

i imagine that 215/45-16...23.7" means: that tire will fit into my wheel well, i was wondering. how do i know if that 215 45 will fit my 16" stock rim? my rear end slides out a lot and needed to replace the front tires so i was going to move my pirellis in the back up front and put the 215's on in the back. thanks for your help!

edit: im running the 205's as we speak. i think 50 series maybe 45 not sure.

Probably.

I would assume that any Quality Care Ford Dealer has what I need to change rev-per-mile in my ECU, no?

And with the introduction of the new mini, we can now find tires in 175/65R15...24". TireRack offers two snows in this size, which is probably the main interest for a tire this size. Yokohama also lists a snow as well, but not at TireRack (currently).

Add in 195/50-15 and 225/45-17, that's my daily driver and road circuit tires which some other drivers might find useful.

The WDS can recalibrate for different tire sizes.

WDS=Worldwide Diagnostic System: Its the diagnostic tool used by ford dealerships.

215 (mm; section width) / 45 (percentage of section width in sidewall height) - 17 (inches; wheel diameter

After that, it's load rating and speed rating...

OE stands for Original Equipment.

I have put some on today but on a rota rims that are 7.5 wide, So far it dont rub at all, but you would not be able to run this wide if you have a drop, if you did, you'd need to roll the fenders as they sit exactly flush with the tire.

It work

update: it does rub on the very top of the fender, not the wheel well, the fender, I need to roll the fenders now and repaint the lip of the fender in the front.... damn it.

225/45 on a 7.5 rim RUBS when it bottom out even with stock svt suspension

Do you think it would be a problem if you had 17" SVT rims (7" wide) to run the 225/45/17's??

I mean...is it the tire or the rim size that is making it rub?

Default Re: A Focus-friendly tire diameter chart

as I told you on PM, I am quite sure a 225/40 would be better. I do not think its due to the rims, I think its due to the width being so high "45"
