slackercruster Posted December 4, 2020 Report Share Posted December 4, 2020 (edited) I got about 25,000 miles on tires They are original 2011 tires on a Ford F350 with truck camper. The center tread has lots more wear than the 2 neighboring treads. (top arrow) Also the outer edge has more wear than the inner tire. (side arrow) How long should front tires last? Do you think I can get another 5,000 miles on them? Any suggestions to more even wear? I'm using 65 pounds all round for tire psi.

k4rs Posted December 4, 2020 Report Share Posted December 4, 2020 (edited) I would replace based on age, regardless of tire wear. I have experienced enough tire problems that I would prefer to err on the side of caution. Extra wear on the center of the tread can be an indication of improper inflation. Safe Travels (or not)...

Do you think I can get another 5,000 miles on them? Any suggestions to more even wear? 1. It would appear to me that your first priority would be to have the front alignment checked. 2. What brand are the tires? 3. In my opinion, your tires should have been replaced before now; think ageing out. They are no different than regular rv tires which have a similiar requirement for replacement. 4. I would be very hesitant on trying to get more miles from the current tires.

slackercruster Posted December 4, 2020 Author Report Share Posted December 4, 2020 Don't have the truck here so can't say about the brand. They came new on the truck from Ford. Quote Link to comment Share on other sites More sharing options...
Kirk W Posted December 4, 2020 Report Share Posted December 4, 2020 Have you always been careful about proper inflation, based on the tire inflation charts from the tire manufacturer? With the tires nearing 10 years old, I would replace them before any long trips but I would also determine what is causing the uneven wear before doing so. A good tire shop might be able to help you, but my guess would be too much inflation pressure. Quote Good travelin !...............KirkFull-time 11+ years......

CFerguson Posted December 4, 2020 Report Share Posted December 4, 2020 ime, tire wear varies a lot based on many things. Proper inflation being #1, but driving style is a solid #2. Only once have i gotten the advertised mileage out of a set (i err on the side of caution on when to replace). 25k on a factory set of tires, i would call it good and get a new set. Sometimes the factory puts on a great set, but those are almost always included in the sales pitch for the pricey add-ons. Quote Link to comment Share on other sites More sharing options...
palmeris Posted December 4, 2020 Report Share Posted December 4, 2020 5 hours ago, slackercruster said: Any suggestions to more even wear? I'm using 65 pounds all round for tire psi. 1.Proper inflation pressure per manufacture weight chart 2. Balance and rotation every 5k miles- 3. Full alignment when new tires first put on, then if you feel it pulling or see any wear get it checked at the next rotation. 4. full lube job at every oil change to keep those front end parts lubricated my 2014 ford came with bf good rich and I got 70k on the first set, sitting at 129 k currently on the 2nd set - Only getting 25k with that type of wear is indicative that they havent been properly maintained or that there is a componet failure in the suspension system.

Ray,IN Posted December 4, 2020 Report Share Posted December 4, 2020 (edited) IMO 65psi is not enough for hauling a truck camper on a 1T pickup, otherwise the tire would be more evenly worn. The tires are load range E most likely, what does the door jamb Federal Tire Placard indicate for front axle gross weight rating? Next wheel alignment, request a total alignment to include thrust angle. If the thrust angle is incorrect, odd front tire wear may occur, and slightly reduced fuel mileage.

Lance A Lott Posted December 4, 2020 Report Share Posted December 4, 2020 If the tire is more worn in the middle too much pressure if it's more worn on both sides too little pressure worn on one side alignment, cupping shocks. Just general rules of thumb. Quote Link to comment Share on other sites More sharing options...
Pat & Pete Posted December 4, 2020 Report Share Posted December 4, 2020 (edited) Not the same animal , but , I had trailer tires that wore similarly . I went through a few pairs of tires . Originally , I thought the axle was bent , as both sides and all sets wore almost identically . Now , on the same axle , using the same rims , tire size and running about 10% less pressure as the only change , I have 3 times the mileage and still have more than half tread left before the wear bars , without the lopsided wear .

Jinx & Wayne Posted December 5, 2020 Report Share Posted December 5, 2020 I think the OEM tires on the 350 were Michelin. On a 2011 vehicle they were probably made in 2010. There is a four digit date code on the sidewall. The first two numbers are the week of manufacture; the second two are the year. 4010 would be the 40th week of 2010 (beginning Sept 26, 2010). Here's what Michelin says about tire life. Quote Keep five years in mind After five years or more in use, your tires should be thoroughly inspected at least once per year by a professional. Ten years is a maximum If the tires haven't been replaced 10 years after their date of manufacture, as a precaution, Michelin recommends replacing them with new tires. Even if they appear to be in usable condition and have not worn down to the tread wear indicator. This applies to spare tires as well. The tire material changes chemically/structurally over time and become much less safe. While you are getting new tires talk to them about the wear problem. They tire pros should have an idea about the problem. I was getting the same outer band wear on the 2017 F-350 with Michelins. It was a toe-in issue.

bigjim Posted December 5, 2020 Report Share Posted December 5, 2020 actually what caught my attention were the references to changing due to age which usually applies to rv tires. I do believe that in this case it should even apply to the truck tires.I I had an issue once using factory installed tires on my TT that had crappy tire wear that I almost did not catch and one had just got down to the cord. I got a decent amount of use consid cering but should have got more. I stepped up one load range and solved the problem. I was planning on getting the TT alignend thinking I might have bent the axle slightly. I was working entry check in at campground once and an obviously newish rv'r came in with a TT that may have been brand new. After checking with us he made a turn to go to his camping spot and as he made the turn me and the guy I saw immediatly all 4 tires were down to the cord and he didn't even suspect it.

bigjim Posted December 5, 2020 Report Share Posted December 5, 2020 (edited) Depending on what you are asking, we informed the guy of his situation. In my case I realized that going to he higher load range and being extra careful about loading and tire pressure seemed to resolve the problem. I never had the issue again. Don 't really know why just happy about it. Edited December 5, 2020 by bigjim Quote Link to comment Share on other sites More sharing options...

Ray,IN Posted December 5, 2020 Report Share Posted December 5, 2020 This NHTSA report on tire aging offers some insight into how long passenger and light truck tires last. It really surprised me that the equivalent of 4 years in AZ sun would cause tire failures. I do not suspect slackcrusters tires fall into the tire aging category. I do think that tire wear is the result of under-inflation and/or misalignment. Quote 2000 Winnebago Ultimate Freedom USQ40JD, ISC 8.3 Cummins 350, Spartan MM Chassis.

The tires are original equipment General Grabbers and if you get 30K out of them feel fortunate. You need a front end alignment and new tires all around. The center wear could be from a lot of things and I wouldn't worry about it because when you install new tires it will be gone but the edge wear is from alignment.
