I am like a previous post that just put a set of G614's on his 5'er 5 days ago, except I put my set of G614's on my 5'er three days ago. The Marathons that were on the trailer were original and just a tad over 4 years old. They gave good service with never a problem, but it was time for replacements in my mind due to age. The reason I went back with G614's was the increased load capacity vs the E rated Marathons. I have weighed my 5'er and each tire is loaded to 3,000 pounds. The G614's give me a bit more cushion.
To add more fuel to this thread, the following is a recommendation from Good Year on how to store tires while still mounted.
From www.goodyear.com
Storing Your Vehicle Without Removing the Tires
Ideally, a vehicle in storage should be placed on blocks to remove all weight from the tires. If the vehicle cannot be put on blocks, follow these steps for tire protection:
Completely unload the vehicle so that minimum weight will be placed on the tires
Inflate tires to recommended operating pressure plus 25%. Ensure that the rim manufacturer’s inflation capacity is not exceeded
Be sure the storage surface is firm, clean, well drained and reasonably level
Avoid moving the vehicle during extremely cold weather
Move the vehicle at least every three months to prevent ozone cracking in the tire bulge area, as well as “flat-spotting” from the prolonged strain of sidewall and tread deflection
Adjust inflation before putting the vehicle back into service
I thought the second recommendation was interesting. Inflate to 25% over recommended maximum (if your wheels will handle it). Hmmmm, G rated tires would be inflated to 138 (I can't do this because my wheels are only rated to 110psi). E rated tires would need to be stored at 100 psi.
Now, where is my popcorn?
