Thank You for your recommendation ot the Carlisle 320410. I was surprised they were made in Vietnam. In Aug. of 1967, I was drafted in the Army to go fight there, but that is OK, as long as they are NOT made in China. They were shipped with USPS "Priority Mail 2-Day" from Brick, New Jersey to Huntsville, AL, that took 8 days. The inner tubes worked very well.

Boy I wish I knew that you were that close to Elora as I only have 7 of them in stock currently. It is a common size that I use in the 18/20 tires. It would have been 19.51 each with taxes added. Of course you might have gotten a better deal.
Carlisle usually has about as good of products as anyone else.
A leak on the side of the tire is usually suspect of a tire cut and will pinch a tube by tire flex until it fails no matter the brand. Examine it carefully inside because it may need a Boot.

95+ of the sidewall leaks here are dry rot related but yes boots are needed on occasion. I had 15 x 650-8 the other day where the equipment owner had put 6+ tire plugs in trying to plug a small puncture and never hit the hole. I ended up have to remove all the plugs and boot the tire before tubing it with a 320420 tube.
It still more multiple thread punctures by thorns that I tube after removing all the thorns.

They crack & fail for two reasons
Firstly they never get hot enough & flex enough when hot to cause the plasticisers in the rummer to migrate to the surface t replace those that the UV has degraded
Secondly no one ( other than me ) bothers to put tyre dressing on the sidewalls to counter cat the effects of the UV rays
This is naturally worse on mowers tat are stored where sunlight can fall on the sides of they tyres 365 days a year
If you cut the printing off the tyre so the sidewalls are a uniform thickness then you won't get the cracking and leaks that originate around the lettering because it is thicker and does not flex as much as the actual sidewalls so acts as a stress concentrator.
This effect is substantially worse on 2 ply tyres than on 4 ply tyres .
