tire size help needed please

[asite57]

im wondering if i can run a 245/45ZR17 tire on this rim?

 

[TLSheff]

A 245/50/17 would be the ideal size on a 17 but if you don't mind being a little off on the speedo you CAN.

Tire size calculator
^^^What I use to compare sizes

 

[asite57]

so wouldnt the speedo being off rape my trans? i was more asking along the lines of if that tire would fit the rim

 

[TLSheff]

Ya it should fit. I would guess they are a 17x7 maybe 7.5 so a 245 should fit nicely.

 

[Bio248]

the tire size has nothing to do with trans abuse, only speedo calibration.

and yes, they'd fit.

 

[asite57]

they could be 6.5 though

 

[asite57]

wont the shift points be off if the speeds off?

 

[Bio248]

hardly.

and a 245 still fits on a 6.5" wide wheel.

 

[asite57]

without tire roll?

 

[Bio248]

what are the wheel specs? come back when you find them.

 

[TLSheff]

Looks like the 04+ 17x6.5s

 

[asite57]

^^^^^^^ it is

stock rims off an 06 GT2

 

[Bio248]

then yeah, it'll fit fine.

however, you'll have a little less turn in response on hard corners because the tire will need to roll before the contact patch actually grips the road and turns the car. this is only because the wheels are only 6.5" wide.

any reason you cant run a 225 wide tire?

 

[asite57]

well my friend just bought some Bullitt rims for his winter car and they have some good 245/45ZR17 summer tires on them so hed just give them to me if i wanted them

 

[Bio248]

it won't be terrible, but noticeable compared to a 'correct' sized tire.

 

[asite57]

thanks i wont run them, ill look for some cheap 225s or new rims lol
