Nice job man, I got the same tires for my winter set as well and am super happy with them, especially the performance in the snow! FYI 275/60/R20's will fit on stock rims without a lift if others were wondering.....

 

Agreed! Love My Zeon LTZ's! Mine Are The 305/65/22.. Rides As Smooth As Stock If Not Better.. Took A Stab @ My Gas Mileage But Beauty Is Pain! Haha

 

Love my coopers as well. Very nice
I added the 3" blocks on mine because if you pull a load it will not squat as bad in the rear and still looks level but I have 2.5 in front

 

looks really good, i dont think they make them in very many 18" sizes

 

Great look. The I have the 305s on my 06 and I love the tires in every way except snow traction. Very poor snow traction.

 

They are a sharp looking tire, shopping tires for my father right now. I am a BFG AT fan but have been giving the Zeons, and the Hankook ATM RF10s a serious look.

 

Nice trucks fellas! I love my Coopers so far and am super pleased with my decision.

 

Looks good! I like my coopers too!

 

Very nice, just the pics I was looking for, thanks for sharing.

Just a quick update...got the Magnaflow cat-back system installed a few weeks ago. Man, I love the sound it makes! Nice and aggressive, but not over the top. Reminds me of some of the muscle cars I had when I was young, a long time ago. I'm 43 years old but that exhaust makes me feel a little younger!

Here are a few pics...

 

Looks really good. Hopefully those Coopers last awhile. My father had a set on his truck and they lasted like 20k miles. They seem too soft to me. How are they holding up?

 

I've got my fingers crossed on how well they wear. Before buying them I researched this forum and another very thoroughly. I saw people giving opinions in both directions, so I'm hoping that it just comes down to driving style. I'm aggressive but I never let the tires squeal and I try not to jam on the breaks or lock up the tires. We'll see!

 

Very nice truck, I think I have the exact same one!

I'm glad you posted this, and this is the first account I've seen with the 275/60/20's. I've been trying to determine which size to get as well; The 305/50/20 appears to be the same height as stock 275/55/20, albeit 1" wider. The 305/55/20 is about 1.25" taller and an 1'" wider and your tire is just about an 1" taller with the same width as stock.

From what I can gather...
275/55/20 31.9" tall, 10.82" width
275/60/20 32.99" tall, 10.82" width
305/50/20 32" tall, 12" width
305/55/20 33.2" tall, 12" width

Have you been able to determine any gas mileage figures with the new tires over stock? How many miles did you get out of the Pirelli's?

Hey James,

You've got great taste in trucks!

I was seeing an average of 15 mpg on my truck's computer before getting these new tires that are about an inch taller. Now, my truck is showing an average of 14.2 mpg. However, the tire is taller and going farther with each turn of the hub, so I don't think the truck is giving me an accurate reading anymore.

I think I need to manually analyze my mileage by tracking miles between fillups at the gas station. But wait, that won't work either because of the tire issue versus turns of the hub per mile. So, I'm stumped!

Any thoughts would be welcomed! Tony

 

Track your mileage with a gps. You can tell how far your speedometer is off also.
