Had these mounted on my new wheels, if you look at the tread it looks concave. This specific tire is rated to fit up to a 10.0 rim on their website under the specs. To me it looks like the shoulder are going to wear too fast, this dies not look normal to me. Looks like they screwed me into thinking they would fit my rim. This is a 11.2" wide tire, the 305 was 13lbs heavier.

Guess it's too stretched out, even the sidewall looks like it's bulging, is it really being stretched out that much? For you guys that squeeze tires on smaller rims experience this ussue with the tread?

Anyone have any ideas if this looks normal!? I wanted inexpensive wheels and tires for the winter and didn't want wider tires since this was my winter setup. But I still wanted some offset and 4" lip.

The other strange thing I noticed is this size is recommended to be aired up to 80lbs cold, the bigger 305 only 65. The tires looks under inflated which is when you see a concave tread like that. It has 65lbs of air in the pics.

The 285x55x20's would be more at home on the stock width 20x8.5 inch wheel. A 10" wide wheel is better for a 305..325 width tire. Max psi is only for loading the truck to the max. 40 to 45 psi for daily use should be sufficient. I bought some Wildpeaks for my Grandsons '07 Pathfinder and he loves them...good looking tires for the price!

Too wide... 9" wide max.

Thanks

Then the specs are wrong. I was going by what their website stated. This is on them now. Will the tire wear itself flat, or will this cause wear issues?

I would keep them and do the 'chalk test' for the correct air pressure for even tread wear.

Here's a youtube video on how to do the test.

Thanks buddy, I saw that video.

I let some air out, down to 40lbs and they look a little better.

I have to say, the tread doesn't lay flat when I hold up a square to the tread. Only 6" looks like it will touch the road, although with weight from the truck I hope it's more like 8-10. The shoulders on this tread seem to drop off a lot on the outer edges, not sure if it's because it's sightly stretched out or just the tire design.

I've seen a ton of people running 285 tires on 10" wide wheels, so I feel better and not concerned it will be unsafe. Besides, the manufacturer recommends up to a 10" wide wheel which is why I went this way to begin with.

Thanks for your input guys.

was wondering how it worked out just got some 285/55r20 for my 20x10 and kinda hesitant now after all the replys

Take a screenshot of their website and Contact them about the rim width spec. I asked them about the 275/70R18 tire. Their site says it will fit up to 9” wide wheels (that size usually isn’t recommended over 8.5”). They replied that the spec was incorrect on their website.
