Difference b/t 50 series and 60 series tires? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

5150 · 04-07-2005, 07:29 PM

I'm doing a 4/6 drop I have 17 inch wheels that came with 235/50's on them. They are in prett good shape so I want to use them. I wanted to go with 275/50's like most of the guys here I see with at 4/6 drop. I have an opportunity to get some 275/60's I wanted to know the difference it will make. I will eventually go with 255 up front, but I didn't want to waste these 235's.

thanks

Are they 235's or 275's? (the one's you're thinking about)

5150 · 04-07-2005, 10:13 PM

They are 275's-they are for the rear. I was going to try to run the 2 best 235's that I already have on the front and then get 275's for the rear.

Yellow, I've got a similar dilemma. Here's what I've come up with so far.

Combo 1: F-255/50/17 (27"T) , R-275/50/17 (28"T)

Combo 2: F-255/60/17 (29"T) , R-275/60/17 (30"T)

IMHO, Combo 1 looks good and is commonly used by members on this board with a 4/6 drop. Combo 2 gives much more wheel house fill and is what ECE recommended to me. Take a look at ECE'e Project 68 pics to see combo2. However, their drop is 4.5/4. They assured me that I wouyld have no interference problems with a 4/6 and the proper BS. Combo 2 doesn't give the same visual "dropped" apperance as combo 1.

So the 60 series will fill the wheel well more? I know the 60 series are a little cheaper and easier to come by.

smokekiki · 04-08-2005, 02:07 PM

Yes the 60 series is taller.70 series is taller than 60.

sactoC10 · 04-08-2005, 02:13 PM

235/50's sound to me as if they'd have REALLY short sidewalls. I have 235/60/15's on the front of mine with 295/50/15's out back. The sidewall height is almost identical, with the rear being only slightly taller.

275/60's are very popular on these trucks and usually quite affordable. I had those on mine when I bought it, one at each corner...but wanted a different look. Also, they rubbed just a tad up front with the drop I have.

Most major tire retailers have a fitment/size chart on their web sites.

Bryan68custom · 04-08-2005, 04:17 PM

Tires are sized by what is called an aspect ratio. For example 295/50/15 is broken down to 295 millimeters wide and is 50% as tall as it is wide. Therefore the sidewall height would be 147.5 millimeters high I am not sure what that works out to in inches because I cannot find my conversion chart.

True, with 15" wheels, but he's talking 17" wheels here. The 17" tires are not as common and much more expensive than 15's.

A 235/50/17 tire is only 26.3" tall and will likely look a bit small, especially in the rear.

5150 · 04-09-2005, 12:06 AM

I'm only putting the 235/50's up front at first because I already have 3 good ones out of my four tires. I really am trying to figure out what to put on the rear.

lamar · 04-09-2005, 03:25 AM

Hey I have 17's with 255/60/17 frt- 285/60/17 rear. No drop yet but I will have room to drop, 17x9.5 rear w/5.5bs, 17x8 frt. w/4bs. Here what it looks like know. And this is close to what I want it to look like.

stllookn · 04-09-2005, 03:50 AM

235 50 17 9.25 inch wide x 26.25 inch diameter
255 50 17 10.04 inch wide x 27.04 inch diameter
275 50 17 10.83 inch wide x 27.83 inch diameter
275 60 17 10.83 inch wide x 29.99 inch diameter

Lamer, nice truck. Are those TT2's? Is the bottom pic a photoshop or actual drop?
