I bought 18x3 inch wire wheels for my 2000 Road Glide. I was told by the rim manufacture 130/70-18 front and 140/70-18 rear were the size to use. I ordered Metzler tires in those sizes. Well the rear 140/70 turned out to be a front. Now I can't find a Metzler 140/70-18 rear to match the front. Doesn't look like they even make one. I then turned to Avon Venom's. They make a 140/70-18 rear radial but only 130/70-18 bias front tire. Now I'm looking at Dunlap's Elites. Looks like a similar problem trying to get those sizes. I guess my question is has anyone else run into this problem and how do I get it solved? Not sure on differences between bias and radial for the Road Glide or what is recommended. What does the Road Glide call for in tires. And if worst comes to worst is there any tires that can be run with another brand and still be safe? Like a Metzler on the front and an Avon on the rear? Thanks for your input.
