The outer treads on my steer tires have apparently worn to enough to expose a different rubber compound. I wondered if anyone else has experienced this. The rest of the tread is excellent.The tires are 245/70R19.5 Bridgestone R250 and according to the charts have been over inflated if anything at 90 psi on a light front end (in spite of the relative heavy wear on the outer treads).Bridgestone CS had no useful info, just said to take it to Larry, Curly and Mo at my local tire dealer for inspection.ThanksJohnI'd post a photo if I knew how

might be an alignment issue. hit any particularly bad potholes lately?

It sounds more like a front end alignment problems. Have it checked, realigned at a truck shop that specializes in alignment, frame and spring issues. If you have the same tires all around the RV, it would be time to have them rotated.Ken

Thanks for the repliesCamber and toe are goodWhen the tires were new, we had to drive westward for 2 days with unrelenting 30 mph cross winds - that took a fair amount off the outer treads. Other than that trial, no suspension issues.I just wanted to make sure that what I'm seeing is not a different rubber layer just above the cord. And wanted to know if there was a particular issue with those tires.

IMO the tires should be inspected by a reliable tire shop. If they are 22.5 tires, I'd use a shop specializing in truck tires....we can't offer you advice on the safety of those tires without a visual inspection. They may be safe, but they just as well may be dangerous. Don't compromise the safety of yourself, your family and those who share the road with you....Dennis

My experience over the years is that the F53 chassis RVs drive much better if the toe-in is set at the maximum positive value in the manual. Affected much less by wind/passing trucks. Much less steering corrections needed. The downside is I have always experienced outer edge tire wear when I have the shop make sure that is what the setting is. Have had a couple RVs in the past that when I got them required a lot of correction going down the road. When checked, one had zero toe-in, the other had been slightly negative. When the tech set them to the high end of the manual value, they drove far better. We always get around 50-55K miles out of rear tires, the fronts I'll change out at 40K due to outer edge wear. I'll swap some tire wear for more relaxed driving any day. I'm guessing your RV tracks like a railroad locomotive going down the road. This is, of course, assuming that the front end is tight and you keep everything properly greased. I'm a firm believer in chassis lubricating at every oil change. I don't think you could possibly wear out the front end on an F53 if you do that. The coach body would turn to dust first.
