someone help me math - Falken Wildpeak AT3W life expectancy

I hate math.

I purchased a set of Falken Wildpeak AT3Ws a couple months back. The truck had 31,246 miles on it. I changed the oil this weekend and checked the tread depth. Depth is 9/32 and mileage is now at 47,531. I've rotated the tires twice now. Should have been three times by now, but...life.

16,285 miles
13-9 = 4 (difference in tread depth)

16285/4 = 4,071 miles per 1/32

If I run them down to 2/32...4071 x 7 = 28,497

28497 + 16285 = 44,782 miles from the set of tires? That's only 20,000 miles off from their 65,000 mile treadwear warranty...

A few comments/questions.

1-How does the tread depth vary across the width of the tire and between tires? If even no problem, if center or edges wearing more frequent rotations or pressure adjustments are in order.

2-My experience is front tires wear faster on the edges and rears tend to wear faster in the center. Front edges seem to wear due to geometry and forces of sharp turns on pavement, like parking or close maneuvering. To get my rears to wear even I need the tire pressure lower than I like and I always want to be able to add a thousand lbs to the box without having to air up the tires.

3-You mentioned nothing about tire pressure monitoring and adjustment and how careful you are about maintaining correct pressures. This is important for maximum wear.

4-The thinner the tread becomes the slower it wears. The flexibility of the deep lugs results in fast early wear.

5-I have never had tires make their guaranteed miles and I am easy on tires and careful with pressure control and rotation. If the tires fall 20 or 30% short on tread wear my experience is you can buy new replacement tires cheaper than you can take the warranty adjustment since they are done from highest possible pricing.

6-I expect you'll get at least 50,000 miles based upon your performance to date.

wear looks pretty even. the edges are wearing slightly but i expect that. I live in WV - curvy roads are not good for the edges of the tire.

2-My experience is front tires wear faster on the edges and rears tend to wear faster in the center. Front edges seem to wear due to geometry and forces of sharp turns on pavement, like parking or close maneuvering. To get my rears to wear even I need the tire pressure lower than I like and I always want to be able to add a thousand lbs to the box without having to air up the tires.

3-You mentioned nothing about tire pressure monitoring and adjustment and how careful you are about maintaining correct pressures. This is important for maximum wear.

I keep them around 40psi cold. once i get on the road they warm up to 42-44psi usually.

4-The thinner the tread becomes the slower it wears. The flexibility of the deep lugs results in fast early wear.

I hope so. I saw that with Cooper AT3s in the past. With rotations I saw 52,000 miles from those tires.

5-I have never had tires make their guaranteed miles and I am easy on tires and careful with pressure control and rotation. If the tires fall 20 or 30% short on tread wear my experience is you can buy new replacement tires cheaper than you can take the warranty adjustment since they are done from highest possible pricing.

This is the first time I've tried to calculate expected mileage. If I get 50k out of these tires I'll be happy.

6-I expect you'll get at least 50,000 miles based upon your performance to date.

:cool:

I know it's been a while since I replied on this thread, but for anyone interested:

I'm at 93,451 on the truck - 62,205 miles on this set of Falkens (275/60/20). I have not done a good job of rotating them...probably only rotated them three times, four at best. Wear is even across the tires at 3/32 tread depth now. Wet weather traction has still been very good, but I'm sure snow traction would be horrible. I'm hoping I don't have to find out. I have a brand new set of Falkens in the garage, just haven't installed them yet. This is the first time I've ever bought the same tire twice. Falken has me impressed.

I’d say you got the best out of those you’re going to get

I have 56k on my 275/65/20 toyo at and am getting new tires tomorrow. If it were summer I would go over 60k easy and may throw them back in next summer as I am switching to some 17” wheels and 285/75/17 in the same tire. Hopefully they’re just as good

I wear out a set per year and the Falkens were out of stock last week. Would have bought two for the rear only and kept the fronts till end of next summer so I had to pick four of another brand tgat were stock. Bought four of the Discoverer AT3 S4 and they performed flawlessly in yesterday's record snowfall here in the GTA. Also looking like a great tire at a great price.

We have 245/65r17XL Falken Wildpeak AT3W's on our CX-9. They wore down 3/32nds in 15k miles from 13/32nds down to 10/32nds. I think that's pretty good wear considering the mountain driving it does. The three W's are winter, wet, and WEAR.

Fyi... the 315/70r17LT's start with 20/32nds tread depth and so do the 35s. I'm trying to decide between them and the Kumho Road Venture AT51's for my EcoDiesel.

Before, when I had a modified 05 hemi Ram, it would chew up a set of any tire that I tried in about 20,000 miles. The stock GY HP's were so bad, it would hydroplane after 10,000 miles, forget about snow. Looks like my GY SRA's are going to make it to 50,000 miles, though on the ED. Looks like we at least have some better choices for tires today. Falkens, Coopers and Toyo's would be on my list, though, being a cheap bastid, I hate to give up any mpgs.

My math says 14/32 with 40,000 miles on 305/55/20E. Keep psi 58-60 (cold) all the way around...was 18/32 new.

Maybe E rubber harder??? Should easily get 100k given DT said the more they wear...the harder the compound and slower the wear rate... I hate the g2s on my Excursion but that truck is 8,000 pounds and nothing has lasted on it....

I had the Hankook Dynapro ATM’s and only rotated about every 20k before mine spontaneously combusted and they still had an easy 20-30k miles left, had 54k miles on them, 265-75-20’s at 65 psi. Rode a little rough, and they were way heavier than stock so economy suffered.
