Sidewall Tire Repair

Hello all!
I've recently acquired a 1975 Dodge Executive and thus the beginning of my adventure in RVing! The RV is need of some cosmetic work but the engineering is pristine. I'm very excited.

My question is about tires, though. It has 8R19.5 size tires on it and have plenty of thread on them. With exception that on the sidewalls, there is some cracking due to the extreme Las Vegas heat. The tires hold air fine and as I mentioned, practically no tread wear. The previous owner just had it parked and let the sun get to the sides.

I'm trying to avoid investing in a new set of 6 tires. Especially with this oddball side. I've considered using some sealant and/or that Flexseal stuff. I've read good reviews of it and thought it might be a good fix for otherwise good tires.

Any suggestions for this newbie on sidewall tire repair or just tires in general?

Your help is greatly appreciated!

  • Welcome to the forum.
    If you are going to drive the MH, you will need new tires. RV tires age out before they wear out.

    A blow out can cause a lot of damage.
    I would start looking for the best deal on your size tires.

    Post some pics of your Executive when you have time.
  • If the side walls are cracked there is nothing you can do except replace them. There is nothing you can buy/do to prevent them from blowing out and you sure don't want a blow out at highway speeds. Be safe for yourself and the other people on the road and replace them.
  • I sure hope you are joking. Your life depends on those tires and I would not drive across town on them. RV tires rarely ware out the tread, but just rot as yours have done. Replace them.
