Yes as a matter of fact. Had some nice period looking Gum Wall Panaracers on my PR-10 for looks. I don't ride that bike regularly so its mostly hanging in the garage. After one year in the Texas heat I noted small cracks all along the gum wall.
I have also had some Gum Wall ChiCom Kenda knockoffs hanging in the same heat for years and no problems. Strange...
I have had minimal problems with oxidation on my bicycle tires after I started spraying my entire bike with Tire Foam then wiping it down after cleaning.
