wheel size help

[chris61210]

i have a 98 Gt and i want to get cobra wheels for it, my stock tire size is 245/45 17 what size wheels will fit? i saw the wheels i want online (17x9) but they recomended 255/45 17 as the tire size. will they still fit with my tire size, or will it look bad?

245's will fit

plz dont put 245's on a 9 inch rim...... 255 is as low as id go
BTW my car came stock w/ 17's too does the comp compensate for the speedo and odmeter difference with the 17 inch upgrade or does it still think you have 16's? i will need to know for my speed cal cuz of my 4.10's

I have 245's on my 9" rim and they suck. My next set will be atleast 265's. I curbed one and the chrome is flaking off. The tread doesnt really protect the lip with 245's.

To keep the tire diameter the same and the speedo the same, i would do a 275/40/17 on a 17x9" wheel. This is the combo the 03/04 cobra comes with OEM.

Chris a 17” x 8” wide rim is probably the best choice for the 245/45x17’s. Although the 245/45x17’s can be mounted on rims with a width range of from 7-1/2” to 9” wide… I think the 9 inchers are too wide as NPIGT experienced. I would buy a set of Cobra rims in the 17” x 8” width for the 245/45x17’s… unless you plan on going with wider rubber.

I also have a 98 GT and in the future I’ve been planning on going with a 17” x 9½” wide Cobra style rim in silver to mount 275/40x17’s all around. I hope I don’t experience any problems with that combo after installing a set of Eibach springs all around looking for a 2” drop.

you can use a 245/40 but the tire will stick out over the wheel a bit and it looks squeezed on but if you are going for the cheapest route then yes it will work just fine.

Optimun size is 275/40/17
