Boards or no Boards?

This tip was given to me, but I would like some verification. I have a 2013 Cardinal fiver 37' in which my wife and I live half time. It has 6 automatic hydraulic jacks; however, some of the RV weight is on the tires. I was told to maintain the integrity of the tires, I should park it up on 2x8 planks instead of the chipseal lot. This would of course raise the entire RV 1-1/2 inches, thus extending the jacks.
So, boards or no boards, that is the question.

If your system is on auto level it will end up at the same place with less jack extension. The biggest enemy of tire life is mot using them, and father time. The clock is up at 7 years max.

As long as the jacks have enough reach I would go with the boards. Of course you can also add blocks under the jacks if needed.

Will the jacks not extend an additional 1-1/2" to adjust for the boards? The unit will be 1-1/2" higher off the ground.

I carry boards with me, but only have the normal 5 er set up with rear stab jack and landing gear...almost all the time use a board under those too along with tires....so seems balanced even if parking is level....plus I keep tire inflated to normal cold max...with x chocks.....good luck with the levelers...

Interesting topic. Being new to RVs, I always wondered if it would be better to store my trailer on jacks and keep the tires off of the ground during storage. I have my boat/trailer on jack stands where the tires are completely suspended in the air during storage.

Thanks and sorry for the hijack.

Try not to store tires on asphalt/chip seal. It will "suck out" the internal lubes, etc. in the tires and shorten their usable life. The 2x (12) is way better. Try not to extend the inner legs any more than necessary (I try not more than 5-7 holes) as there are only 13 holes on the rear of mine and 15-17 on the front. The more stable and less inherent movement, the longer everything will last.

I always put boards under all 6 of my jacks.

#1 Jacks extend 1 1/2" less.
#2 Larger base.
#3 Keeps moisture off bottom of jack plate.

tires

Interesting. There are only two things that will cause a tire to "go bad" one is UV rays which the sun puts out and dries the tire out causing cracks in the tire that eventually lead to a blown tire. The other is over inflation, if you pump your tires up to max psi and drive down a hot asphalt or concrete highway the tire will "grow" or the air inside will heat up from the friction between the rubber on the tire and the road surface causing a blow out. The boards between the tire and road surface really has nothing to do with the tire going bad, for the most part it's there for leveling of the vehicle. To put a vehicle on jack stands during winter (I do this to my cars in storage) is to prevent flat spots on the tire, if all the weight is on the vehicle pushing down on the tires it really doesn't matter what it's sitting on they will eventually have flat spots.

Both my full size van and Toyota truck are run at the recommended maximum air pressure all year long. It was suggested by the tire shop.

I used to park a car that was only driven on weekends at a storage yard and tires were inflated to the maximum suggested pressure. It still had flat spots when taken out for a drive but they disappeared fairly quickly.

I do have my boat on jack stands as it isn't used as often.
