OEM 285s On 20s?

[Ofishl1]

I know 295”s will run on my 23 RAM Laramie 4x4 CTD, not in question; what I am most interested in would be to hear from those that have gone from stock 285s x 20 to 295 60 20s and did experience a better ride from the increased sidewall.

The 285x65x20s on this heavy front end feel like solid rubber hitting curbs and almost everything.

Maybe it’s because they are the OE Firestone, too, but I am unsure; I've never had these.

The truck/wheels are too new to dump a bunch of money on 18-inch wheels.

Looking at the Toyo AT3 in the 295.

The thicker sidewall is better than the paper-thin ones.

I ran the Falken AT3 35x12.50/ 18 and never had any issues.

I was so glad to get the junk firestones off my truck.

They didn’t last 25k before I had to replace them.

I also had Toyo, and those were decent tires until the tread wore half out, and then they became like slicks on wet pavement.

Thanks for the reply; yeah, someday, 18s.

I suspect the FirestoneTrashforce OE tires.

I have read some good things about Falken, but I am not sure they come in 295; I must check that.

I have to assume "any" more sidewall has GOT to help.

Hopefully, it will not make it side to side squirrely.

You have to look at the ply rating E = 10 ply and F = 12 ply.

If you are looking for a smoother ride, go with the 10-ply with a max PSI rating of 60 or 65 psi.

If you do this, keep in mind you will lose load-carrying capability.

You must also change your min/max psi settings to avoid a low tire pressure warning.

The F-rated tire will have a max PSI rating of 80 psi and have a higher load-carrying capacity.

This is what the GVWR and GCWR are based on from the factory.

One caveat: some E-rated tires will have a max psi rating of 80 psi.

So make sure to check that when purchasing your next set of tires.

I hope this helps.

Beaman, Yes, Sir, I see the Toyos and Falkens are rated for 80 psi and up to 4000lbs+ per axle; seeing how this truck will be on the road most of the time as we haul the RZR for the real off-road work, hunting etc, I am debating on just going with the Michelin LTX.

We don't see much Snow or rain here in AZ. I know they are not the meanest-looking truck tires, but I hear they are hard to beat for towing, ride, and comfort.

I have had the BFG, Nitto Grapplers, and Toyo AT3, and none of them seemed to last very long on a 4x4 truck or Jeeps, maybe yes.

I know some will claim high miles out of all those, but not my experience even rotating religiously every 4-5K.

They are just too much money to burn up at 25-30K, and the Grapplers were the worst on my lifted ECOD 4x4, slicks at 25K.

The Toyos are 63 Lbs, whereas the Falkens come in almost 70 lbs, which is a jump in rotating mass, in my opinion.

If I were running dirt roads all the time, I wouldn't care, but for highway running and towing, the Mich LTX M/S is 55lbs in a 295, the same amount of money as the others tho.

You can’t go wrong with the Michelins.

My parents and in-laws run the LTXs on their (please forgive me for the words I am about to say) Ford F250, and they pull 5th wheels cross country.

When purchasing tires, ask what the date code is on the tire.

The tire will have a build date stamped into the sidewall.

It reads in 4 numbers, something like 1222.

This means the tires were built in the 12th week of 2022.

So make sure you are not being sold a set of tires a couple of years old before they go on your truck.

OMG , you said the dreaded F-Word on here!!!

Good advice on checking the date code.

You know, thats a good point; I completely forgot about checking that; thank you for the reminder.

I went with the 285x65x20 Michelin Defenders, which run 34.5 tall and almost 12 wide, and they are very smooth, no comparison to the Firestones.

We towed the big trailer very well.

We are still working to determine the best-unloaded running pressure.

They set a good contact patch at 60F 55R with a nice ride.

I ran them at 75-75 towing and did very well.

It is not the "tough truck" look the Toyos or Nittos offered from past trucks; however, I am happy with this ride and handling combined with the Thuren setup.

This size does an OK job of filling up the well and affords a little more sidewall.

I don't know how it could feel/handled much better.

Look sharp!

I think the 285/65s fill out nicely.

I went with Yokohama in the same size.

I am getting them put on next week.
