I have 35 toyos mt on my 08 f250. I believe they on the stock rims. The previous owner had them or the service place had them aired to 80 psi. The tire reads 65 max. What that about, should i lower them. I am looking for best street performance and no tow psi. What should i set to for best economy. Thanks for reading. Again no towing will be done. Also will an all terrain be better or are the toyos good for street driving

 

One thing is certain. You should not exceed the pressure rating on the tire sidewall. Where you set them is dependent on the load, but should never exceed the rating.

 

for best economy run the tires at near or max PSI rating..

for best comfort run less PSI till your happy...

i run my tires at max PSI all the time, wether loaded or not...but i like my trucks stiff ride..

 

More info, please. Specifically what size tires, rims.

About pressure, yes that is high but the pressure on the sidewall is maximum load @ 65 psi COLD. The reason I mention this is you might be surprised the amount of pressure increase when the tires are hot, under load, moist air (hence the nitrogen rip-off) so an occasional over-pressure doesn't mean your tires are going to blow up or you are going to fly away like something from a Flubber movie.

How much pressure to run is like asking what food tastes like.

You generally should run the pressure that allows for a full contact patch across your tire.
This can be accomplished with a chalk line across the tire and driving in a straight line to observe if the whole of the tire is making contact.
This will vary GREATLY with load and you'll probably be surprised at the pressure differential between front and rear when unloaded.
Too wide a tire on a stock rim will tend to wear the center of the tire out prematurely but will protect the rim in extreme wheeling.

The factory puts worst case scenarios (read:Liability) on the inflation label on the truck and rarely does the truck need the full inflation.
A little effort in determing the PROPER inflation levels for your truck in various conditions will GREATLY improve ride, handling and longevity.

 

I have the 35x12.5x20 Toyo MTs and I run them at 45 psi cold empty and 55 psi loaded, they have a great wear pattern and still have over 50% tread after 28K....Mine is a V10....

Having them at 80psi is not only IMO dangerous but it's gotta make the truck ride terrible....

 

This part of your question hasn't been addressed yet. You don't say whether you actually off-road the truck in mud, but it sounds like maybe not. And if that is true, then yes an AT tire would be better for on-road and light off-road use. Mud terrains don't wear as well or ride as well on the road. Having said that, you might as well run the tires until you need new ones. But consider an AT next time.

You have the wrong load rating for your truck. It is designed for an E load rated tire. You are running a D rated. You don't tow or haul heavy, so that's not a concern except for the pressure confusion. But next time go with an E rated tire for maximum life and road hazard protection.

The air pressure confusion will be a constant problem for you. Less experienced employees at shops you visit will look at the safety cert label on your door jamb, which gives recommended pressures, and that's where they will set your tires. Problem is, that label is for the OEM E rated tires, not your aftermarket tires. So you will have to always check it yourself. Not a big deal, since you should always check the work of others anyway.

 

Do you have those 35"s on the factory rims? Is that an E range tire? Thanks

 

My toyos are 33x12.50 and are E rated.

 

Stock wheel?

 

I have the 295/70R17 MT's on stock wheels and they are 80 psi. They ride pretty much on the full contact tread, I run them at max psi all the time since it's too much hassle to air up and down when I need to tow the trailer.

 

Happens all the time, the dealer or shop looks at the door sticker, sees the truck requires 65 or 80 PSI and airs them up, not even bothering to pay attention to the tire rating at all.

I've had it happen several times to me. Very obvious on my truck when I get in and I see the TPMS light off when it's been on since day 1 with my AT tires. I make sure to point it out to them every single time.

 

Hey guys how are the Toyo Open Country M/T on the highway? Was looking at thoes and the Nitto Open Country M/T but some guys are saying to stay because they dont track good on road.
Thanks

 

The M/T's handle like an A/T on both wet and dry pavement. I currently have 3 trucks with M/T's, and a truck with A/T's, and honestly you can't tell the difference on the pavement.

Unless some other magnificent tire comes on the market, I can't imagine running anything different.

BTW, on my '02 and '03 CCSB Diesels, both with 38x15.50x18 M/T's, I run 38 in the front and 35 in the rear light, and 50 in the rear towing. Excellent life, great ride, trucks handle perfect, and with Counteract in the tires they have perfect wear patterns.
