Replacing tires this week on our expedition TV, tires are 3 1/2 years old with 40k miles on them.

Just replaced my generals at 50k. They were down to the wear bars. Replaced them w/Michelin. The truck tows the TT about 95%of its miles. It is not a dd.

If the tire is less than about 6 years old, it depends on tread depth across the tread.Use a tire tread gauge. If any tread segment is less than 3/32nds deep, it's time for new tires. If there is more than 1/32nd difference in the tread depth across the tire, then the tire has suffered either alignment or inflation problems. So fix the problem before you replace the tires. If the problem is the tread has worn more in the center of the tread, then that's caused by over-inflation. If the tread has worn more on both outside edges of the tread, that's caused by under-inflation. If one side of the tread has worn more than the other, that's caused by alignment (or maybe worn shocks).If under or over inflation is the problem, then find the load/inflation table for your type and size of tire (brand of tire doesn't matter) and go by that table. A good one is on the Toyo tire website.

When tires are about 5 years old, look at the sidewals carefully to be sure there are no weak spots or excessive checking. If the tire looks good and still has more than 3/32nds tread remaining, then run it until it's about 6 years old before retiring it for age.

You shouldn't need tires at 40k in 3.5 years. My F-150 OEM tires now have 36k miles in 28 months, and still have 7/32nds tread left, with no indications of alignment, inflation or shocks problems. So they're probably good for at least another 30k miles.

My Ram was purchased new in Nov of 07 with Generals on the truck. I rotated them every 5,000 miles because it is a 4X4 to even out the wear on them. Replace the Generals at 41,000 miles on them at the start of the camping season April 2011, with Michelin M/S2 tires. The General tire wear was all most down to the 2/32 limit. The Michelins are rotated every 6,000 miles and have shown very little wear at 72,000 miles, April 2014. These should last for the rated 60,000 miles life that Michelin warranties the tires for. This should be reached around 2017 on my truck. I am retired now and the truck is not driven as much as when I worked, but the truck will still see about 10,000 miles a year now.

I think that Michelins tires present the lowest cost per mile and provide the best tire life on the market now.

If your tires require pressure over 50 psi, have metal valves installed instead of rubber.

When they need to be replaced. If you are not sure when to replace your tires go to a tire shop and have them check the tread depth and condition of the tires.

My last SUV I replaced the Dunlops at about 38k miles (6-1/2 years old). My concern now is the new TV I have (14' Tundra) has the lower profile 20' tires. It was the only tire that came on the Limited model. Took it's first trip towing the RV last weekend. Got a disappointing 9.8 mpg.

It did ride better than the softer suspension that was in my 4Runner. Not as much bouncing.
