New Tires

Will 255s fit ok on my stock rims? I was going to do a complete rim and tire change in the spring but decided I will save the $520, spend it on cams and a HPS hardball intake.

with ease, make sure they are 255/40's, not 255/45's. Good choice! love the stock look N E ways

I've been running a 275x40 out back since the first tire change in 2001 with no problems.

So 275s are ok on 17x8 rims? If thats the case I will run 245s up front and 275s out back.

yeah they are OK but will bulge out a bit.

255/45 should be fine, its not far from stock tire size unlike 255/40.

275's ftw

 

[Winters98GT]

I run 255/45s with no issues

then your speedometer is slightly off

stock 245/45 height =25.68"
255/40 height =25.72"
255/45 height =26.04"

the 255/40 more accurately represents the stock tire height.

Yes, I run 245x45 up front with the 275x40 out back, both on 17x8 rims. I have since my first tire change in 2001 with no problems. They do bulge slightly, but I like the look. From the side the profile is very close to the 245x45 but they look slightly "meatier" from the back.

If you have no problems with that then thats probably what I will go with.

1994-1995 Cobras come factory stock with 255/45/17's in their 17x8 wheels

Any other 17x8 wheel ford decided to use 245/45/17


Weird i guess

numbers are off

245/45 is 25.7"

255/45 is 26"

255/40 is 25"

 

[mustang50v8]

as for the 255/40, its wrong on there. Its closer to this

I measured two brand new this weekend. they were 255/40's and measured 25.39.

All my calculations are correct, except for the 255/40. The 255/40 do show 25.03 on the calculator

 

[isjoining]

right, I was just pointing out the 255/40 size, just happened to include the other two at the same time.

Looks like going with 245/45 up front and 275/40 out back will keep her around the stock diameter.

It wont throw it off that much either way.
