Jim,
you've been a great help before and I had another question for you.

I am getting 18x8 for the fronts and 18x9 for the rears.
My first thought was to use 225/40 18 for the fronts and 255/35 18 for the rears.
However I really want to try out the BFGoodrich g-Force KD and they do not offer the 255.
They do however offer a 265/35 18... so my questions is:

Do you recommend I still use the 225's up front or should I match them with a 235?
Here are some numbers I came across, but am still not sure what would be a better match.

Specification
a. 235/40-18
b. 265/35-18

Sidewall
a. 3.7in
b. 3.7in

Radius
a. 12.7in
b. 12.7in

Diameter
a. 25.4in
b. 25.3in

Circumference
a. 79.8in
b. 79.5in

Revs/Mile
a. 794
b. 797

Difference
a. 0.0%
b. -0.4%

Thnx again Jim

I think it would depend on the wheel width and offset as to whether it will fit. I would say that the front will be very tight.
I am not sure it would fit.

Jim

 

if what woud fit... the 225 or the 235?
front offset is 58 rear is 68...

anywhoo, placeing fitment issues aside, which tire would be a better match for the 265s (the 225s or the 235s)?

thx

anyone..anyone???

 

leo,

i think this is a question better addressed by those in the racing and competition forum. particularly by jzr. perhaps u should PM him?

i believe you'd be closer to the stock stagger ratio by going 225/265 rather than 235/265 for whatever that's worth. but then more rubber to the ground.... definitely one for the track masters.

good luck,

 

thanx man
I shoot him a pm

 

I read in the racing forum that the stock stager is about 1.5", so converting the mm to in for front and back:

225/265 is about 1.57"
235/265 is about 1.18"

So with 235/265, you'll be getting more traction up front than the stock set up, which can be offset with a bigger sway bar. 225/265 looks like a better match, or at least it's closer to the stock stagger.
