Frank Cerutti Posted March 13, 2018 Share Posted March 13, 2018 I have seen a 1909 model G REO runabout fitted with Goodyear detachable rims fitted with straight sided tyres. There is a YouTube video at https://www.youtube.com/watch?v=Mf8Icjt5smc titled "Goodyear's History (Part 1) which sets out the facts. As explained in the video, Goodyear was a latecomer to the tyre business and trade restraints limited Goodyear's production of straight sided tyres to 1 and a half percent of the clincher tyre market. Now to the purpose of the history lesson. Goodyear detachable rims could be ordered for either straight sided tyres or clincher tyres. The detachable rim has a steel felloe, an inner slide-on ring which carries the inner edge of the tyre, an outer slide-on ring which carries the outer edge of the tyre and a split lock ring, the tail of which hooks into a hole in the steel felloe to hold the lock ring from moving away from the felloe. The outside ring fits over the lock ring to hold the lock ring from becoming dislodged radially. Air pressure holds the whole arrangement in place. The inner ring and the outer ring are identical The model G REO mentioned above has a complete set of hardware for straight sided tyres. Does anyone have the necessary hardware for clincher tyres? Just 8 clincher rings are needed. Trade straight sided for clincher rings? Link to comment Share on other sites More sharing options...
Hybrid Posted March 26, 2018 Share Posted March 26, 2018 (edited) Thanks for the history lesson. I didn't realize Goodyear's role in getting away from the clincher rim. What size are your Model G rims? I have a 10 Model R with the straight side Goodyear rims (27").

Frank Cerutti Posted March 26, 2018 Author Share Posted March 26, 2018 Hi Hybrid The model G has 28" x 3" tyres, which puts the rim size at 22". So what size are the tyres fitted to your model R? Have you ever seen clincher rings to fit your car? Regards Link to comment Share on other sites More sharing options...
Hybrid Posted March 27, 2018 Share Posted March 27, 2018 My R has 36 x 4 1/2. 27" rims. I have never had clinchers for it. Most of the 10 Model R's I have seen had the same wheels I have. I will keep an eye out for some for you. Link to comment Share on other sites More sharing options...
Frank Cerutti Posted March 27, 2018 Author Share Posted March 27, 2018 Hybrid 27” rims and 36” tyres is a bit big for me to comprehend! Thanks for the offer to look. Regards Frank Link to comment Share on other sites More sharing options...
