would 8" or 8.5" wide wheels fit on an eg or dc chassis? if so, what offset would be best for the rears?

 

Tire Rack does not list any wheel wider than 7.5 inches wide for this vehicle.

 

hey, if you want, you can make a 8 fit.. but you may need to roll fenders and offset needs to be spot on. also your tire choice will affect if you can or cannot run the 8 inch wide wheel

 

I have 15x8.5" on my EF hatch with 225/50-15 Kumho V710s. It did not fit without alot of fender "rubbing" with a 2 lb sledge. That is my race setup. For the street, I have Kosei K1s in 15x8, 22mm offset with 215/45-15 Toyo T1-S. Tire Rack has Kosei K1 15x8" blanks in 12, 22 and 32mm offset which they will machine to your bolt pattern and hubcenter bore for $189 or $199 per wheel. They are not listed on the website, but if you call in, they'll give you the info.

 

thanks man. i appreciate it
btw, what offset is your 8.5 set for the rear?

 

My 8.5s are 5.75" backspace, and I run one 1/4 spacer to keep the tires off the trailing arm.

 

225's on a 8.5 rim? isnt that pointless..running stretched tires..

What makes you say that? A stretched tire as you call it will have alot better repsonse to inputs, as the sidewall is already flexed, and the movement of the steering doesn't have to wait for the sidewall to flex before the car starts to change direction.

If I could, I'd go with 9" wide for these tires. They're a 225, but the width sidewall to sidewall is more like 9.75" when they're not mounted, and the tread width is 9".

Kumho is supposed to release a 245/45-15, and if they do, my wheels will be widened to 10".

so for a 5.75" backspace, wouldnt that equal to an offset of 1.5"=-38mm offset? since the 8.5" wheel is 4.25" in half and offset is the distance from the center of the wheel, and backspacing is the distance from the inside face to the inner end of the wheel?

Sounds about right, except for 2 things:

Backspace is a slightly different measurement than offset. Backspace is the distance from the hub mounting face to the inside edge of the wheel, whereas offset is hub mounting face to the tire bead seating surface. That would be about an extra 3/8" on my wheels.

My wheels are mounted with 1/4" spacers, making the effective backspace of my wheels 5.5".

So now 5.5" backspace, minus 3/8" outer wheel lip, equals 5.125" on the inside of the wheel. My offset calculates out to be negative 22.225mm or .875" (5.125 minus one half of the wheel width 4.250).
