how big of tire ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

stepside454 · 12-13-2003, 04:02 PM

I have a tire size question. my truck has 255/60s all around now. Im planning on 275/60s on the rear.
If they'll fit Id even like 295/60s. anyone know if they'll fit my lowered stepside on stock 8" rim?
may be to tight, let me know please, John

Yes, either will fit just fine. Although I think a 8" wheel is a little narrow for the 295's.

275 will be pretty nice. It will raise the rear about 1.5". The 295's really need a 10" rim to look right and have a good footprint.

Does anyone make a 295/60? The 275's on 8's would look pretty good & I'm w/the others.... anything bigger needs a wider wheel.

275/60'S have a 6 1/2" sidewall. A little tall for a lowered truck like yours, IMO. Maybe 295/50's?

I kinda like the filled wheel well(drag race) look

r0lf- · 12-13-2003, 08:18 PM

Then you need to lower the rear more

Too much rake and its not gonna drive well at all. Unless you only want to go in a straight line. BTW theres nothing wrong with that!

**swervin ervin** · 12-13-2003, 08:47 PM

255/60's are 27" tall. 275/60's are 28" tall. So the overall effect will be 1/2" higher in the rear.

stepside454 · 12-13-2003, 08:59 PM

yeah, actually Im lookin for a lil taller

TIMSPEED · 12-13-2003, 09:37 PM

How low is your truck stepside?

shavn80 · 12-13-2003, 09:45 PM

don't mean to threadjack but...

with a 10" rim in back, whats a good backspacing? 5 1/2"?

stepside454 · 12-13-2003, 09:53 PM

Tim, look @ first thread

**swervin ervin** · 12-13-2003, 09:56 PM

With stock 8" wheels, they have a 4" backspace. So, with a 10" wheel, anything from 5 to 6 inches works. A 5" BS would put the tire out 1" farther than stock, 6" would put it in the same place as stock. 5.5" would work well.

Well, since you're sitting at the top of a 27" tire, I would guess it's a 5/7.
