I have had a slow leak in the right front tube on the '52 8N, for while. The poor old tube is poking out around the valve from being rusted out. I've been thinking about some new rims for awhile and finally decided to go the 16" implement rims/tubeless tires route. I read through some older posts about these. It seems the 5.5 x 16" tires are the best bet. Exactly what size do I ask for at the tire store? I mean car tires come in like 205/60R/16 sizes? Maybe better to look for motorcycle tires? I don't have a loader on the tractor. Thanks, the tires is getting as "leaky" as I am...lol
