Quick wheel help plz

[WA_TRD_83]

Hey guys... I'm just confirming what I dont wanna know.. But maybe someone will know definately or not..
bought a bunky ST162 Celica today..

They run 14's from factory.
wheels are 14 x 6 +39offset
tyres 185/70/14

just so happens I have a set of 17's in the shed from a subaru ... Ideal!.. or so I thought..?

17's details are - 5x100 PCD
17 x 7 +55offset
tyres 215/45/17

here's my quick test fit...




On the front they are ok. Clear the suspension, and just clears the brakes by about 1mm

But on the rears it doesnt even come close as the tyres connect with the bottom of the suspension




Now, is this something that can be solved by going down to a smaller 40profile tyre?..
or as I suspect, is the offset of the wheel the whole problem??

If its an offset issue, then what offset should I be running with 17's to fit the Celica?

cheers

Spacers are your friend

after a few hours of research on the net, I'm pretty sure I answered my own question.
offset is way too high.
needs to be more like +35 to +40ish

some bolt on spacers would fix this. but there's a couple of hundred dollars spent, and they arent legal
hmm...

might be easier to sell these wheels and actually buy a set that fits with the right offset

You should try to keep the offset as close as possible to the original... especially on the front... otherwise your geometry will be all wrong and your car will handle like teh p00h!
Spacers work in some instances but I believe that in your case your new rims stick out further than the originals and as such couldn't be fixed by spacers.
Note: I may be wrong here but from memory +39 offset means the hub face is 39mm to the outside of the centre line of the rim.

Also you should also make sure your rolling diameter is almost the same, this can be fixed by reducing the profile. By my reckonings 205/45/17 (slightly bigger) or 215/40/17 (a bit smaller) would be the go for you.

The tyre placard on my series 2 SX says 195/60/R14 for the stock tyre size (not sure if series 1 wheels are narrower or not though)....205/40/17 is the best 17" match for rolling diameter
