Tire recommendation for zq8, 18"

TH3s355 · Nov 28, 2010

Hello, I have an 05 colorado with the zq8 suspension.

Currently, I have older sierra wheels with 265/70/16 tires which is roughly a 30.61" tire. The truck does not rub a whole lot on turns and such in the parking lots, but the chevy lean on the driver side front makes it rub quite a bit when I go over bumps.

I am putting an 18x8 titan rim on the truck and am looking for suggestions for tires. I don't want a 3" low profile tire that has no ride comfort or rim protection. I don't want to lower the truck. I would like a decent tire that has some meat on it, well as much as possible for this application.

I was thinking a 255/55/18 might work. This is roughly 29.04" which is a decrease of 1.57" or approximately 3/4" further away from the wheel well. I was thinking that, along with some lovin from a hammer might eliminate the rubbing while still providing a tire with a 5.5" tire wall.

Any thoughts or suggestions?

Thanks,

Jim

Are you lowered?

My stock tire size is 235-50-18. You could also go with 245-45-18, or 245-40-18, but the 40's will give you a "rougher" ride.

I am not lowered any more than the stock zq8. Also, I don't want to be lowered any more though. What is the width of your rim?

If you are not lowered and sitting at stock ZQ8 height, go with the 235-50-18's It's what comes stock on the xtremes and newer zq8's with 18" rims

The 235-50-18 will be a low profile tire, but they ride pretty good.

:lol: 235/50 is NOT a low profile tire

If you are wanting a taller tire, id go with the 255/55/18 at 29.04 or a 245/60/18 at 29.57

TH3s355 · Nov 28, 2010

Would the 255/55/18 ride better or worse than a 235/50/18? As far as noise and smoothness of the ride?

Thanks,

Jim

I've got 245/55/18's on my Titans and it rides nice. But I'm gonna go to a lower sidewall next set.

I found some 245/55/18's a friend has. Would those work? Would the noise/ride be ok?

Check my pics with the Titans on. Same size.

pantera · Nov 28, 2010

I think they would be perfect for what you are looking for. A little taller and wider than my stockers.

im running 235-50-18 on titan, and the ride is great.

TurboAl · Nov 28, 2010

I run 255x45x18 front and 275x40x18 rear rides and handles great. no tire noise at all.
on factory 18x8 ZQ8 mags.

DAmn i did not relize you were running tires that wide on the 18s

TurboAl · Nov 30, 2010

yea, the backs are 275's just put them on last week. look in my pic album to see them.
will take a pic of them on truck and add it. just barely fit on the rim.

Looked at a friends tires he had, but they were junk. Found some BFG 245/55/18 cheap at discount tire. Decent reviews there and elsewhere. For $77 a tire, I am willing to give it a shot.

If I get the chrome caps done by Saturday, I will post some pics.

Thanks for all the advice!
