275/65/18 to 275/70/18 upgrade inside

[Littlefield82]

Had the stock Goodyear Wrangler Territory AT's that weigh 38 lbs each as measured by my bathroom scale. Just had General Grabber ATX 275/70/18 116S SL installed by Discount Tire and they weigh 44 lbs each per the General website for this exact tire. Short 18 mile drive home told me that the new tires ride noticeably smoother than the Goodyear's and only slightly louder. I doubt anyone could tell that they are louder but I was able to do back to back driving and notice the difference. My speedo reads 60 mph and Waze shows 62-63. I was only off 1 mph before the tire swap.

I've reached out to General to see what their recommended tire pressure is but for now I'm assuming 35psi (same as stock).

I'll also add that on my last trip of 239 miles the computer said I got 22.2 mpg but my hand calcs based on the pump resulted in 21.45 mpg.

Here is the old (first two pics) followed by the new...

Do you have a lift or level on your truck? Your setup looks amazing, but I'm at least a year or 2 away from my accounting department (wife) allocating me the funds for a lift lol.

great swap. I am looking to do the same, although those tires are hard to look up online. Only E rated seem to appear.

No spacers or with spacers? TIA
