Is this the ideal Tire size for 17x9.5 +28 front/18x10.5 +22rear combo:

265/30 front
285/30 rear

I tried using the JimLab excel file and I am just confusing myself.

94 RX7
Feed front fenders
Burnout rear fender flares

TIA, Luigi

 

You'll have difficulty finding 30 or 35 series sires for 17" wheels. Any reason you went w/ 17" front and 18" rear wheels?

For that setup, I'd run a 255/40 or 265/40 front, w/ 285/30 or 295/30 rear.

you could fit a 275/40 up front, but it's going to be alot taller than even the 295/30 rear.

 

what wheels are you getting sounds like this is gonna look good

 

Wait a minute... +28 and +22m offsets? Is this a widebody car?

 

^^

 

Should have kept reading past the wheel specs, apparently...

 

Wheels are TE37s. And I meant to write 265/40 not 30, that was my mistake.

 

Looks like it's time to redo my spreadsheet and make it a bit simpler.

 

Exactly what Ptrhahn says....adjust to match up with the sizes offered by tire model of choice.

 

oh man im going to need pics of those on there its gonna be sweet

 

Probably not, I'm slow

 

Just recieved my wheels (pictures by vendor):

(I'm thinking out loud, but would still like to know if this is correct):
When considering purchase of tires, isn't it important to to have the diameter of the front/rear wheels as close as possible? With that said, and according to Jim's spreadsheet: 255/40/17 and 295/30/18 are the closest combo. The only thing that may effect this decision would be the offset and how close it comes to the fenders (Feed front/Burnout rear).

You can have small variances....I'm assuming you have coilovers to adjust the ride height? 255/40s would be a great fit up front.....265/40s would have less understeer with those big rears.

 

those wheels are pure sex!!!! i wouldnt go with a 255 up front max id go would be a 245 and a 265 in the rear, stretch them a little bit it will look so sexy.

 

Some people care about performance, not if it looks sexy to you.

 

I do have coilovers (Tein HA). It is very difficult to find 265/40-17 tires.

 

sorry for jakin your thread wptrx7, nice wheels

 

no problem here
