Is there an official ford guidence for "Approved tire size"?

[Rp930]

Ok.

https://performanceparts.ford.com/vehicles/Ranger-packs

Considering it's the same size as the Tremor tire, and also sold by Ford Performance I'd say it's a safe and logical assumption.

It is literally the largest tire size listed by Ford in any remotely official communication regarding the Ranger.

I would say those are but I’m not sure if the the Ford tune will allow sizes over that. I didn’t try it.

Edit: Yes the tune says up to 265 70 17 tire size so I agree. You are correct.

so the Ford performance pack paper work states warranty is covered with the package and tires up to 265 70 17 or equivalent based on the factory rim size you have.

It's not about weight of the tires, but the additional rotational forces required to turn those tires,
as well as increased stress on suspension parts.

I get that, I'm asking how that's any different than if I towed 7500 pounds every single day. Unless I'm misinterpreting something here- if I had a bone stock version of my truck and towed 7000lbs every single day for 3 years straight and my diff exploded (provided im still under mileage/warranty restrictions obviously) that would be covered.

but driving the same mileage with a 33 and the same failure occurring (no trailer) wouldn't be covered? I'd argue towing the trailer has a much greater strain on the driveline of the truck than 40lbs total of tire.. that's what i'm looking for clarification on.

Edit: not being argumentative as I acknowledge the heavier wheel/tire combo definitely strains the truck more than if it was stock

So a question Phil.

Does that stated PSI the same for all tire MFG’s given the same tire size is used?

in my case, I went from OEM Hanooks to BFG KO2’s but same size.

thanks in advance

Hi John,

The stated PSI is for the tires as delivered from the Assembly Plant. For aftermarket the tire manufacturer usually have a matrix for suggested tire pressures which you may consult. There are some threads here that show how to use a chalk method for determining the best pressure

Knowing your individual wheel weights is of benefit too if you can find a scale capable of determining individual weights.

Best,
Phil

Hypothetical for you Phil- how could Ford deny a warranty claim on a differential for example, because I went to a 33" tire with a total increase in unsprung weight 10lbs/whl, when the truck is rated to tow (IE addtl unsprung weight...) 7500 lbs from the factory?

I guess what i'm asking is how is the larger tire any more wear and tear on the vehicle than if I maxed my truck out every day of its life, whether it's payload or towing?...

Edit: math.

stock sport tires 36 lbs + stock rims 27lbs = 63 lbs
wildpeaks 50lbs (p rated) + KMCs 23lbs = 73 lbs

Hi Matt,

I would take a dealer tech statement with a grain of salt...or more than likely a whole salt shaker. It would be up to Ford to make that determination, not a dealer tech. Also, I believe the Tech in question was not USA... Things may be different overseas...don't know..

Best,
Phil

If they are denying warranty claims because of changing tire sizes, nobody around here should be getting warranty work done.

Puerto Rico, we get the US spec ranger.

I don't know how we are classified (Or divided) at the corporate level, but we are a territory of the United States.

Do you know how many miles that ranger has?

 

[BettaRanga]

How big are his tires??

Getting warranty work done is a hit or miss proposition. There are a lot of mechanics that dont like because the factory does not pay as much for warranty work. It also depends on your attitude and relationship with the service dept. when you bring it in. When you start modifying stuff, you take on some responsibility.

Just want to clarify. You mean the dealership makes less money on warranty work, right?

Technicians don't get a differently hourly rate on warranty repairs do they?

 

[mtsoxfan]

Warantee work pays less time to repair than non warantee work.

I guess it depends on how you go abut it. I have a 6" lift and 33s. Truck was built by an upfitter and ordered through Ford. FMVSS compliant, full factory warranty covering all of it, financeable and insurable. Part of why I went this route.

I’m glad that purchasing through an upfitter or whatever gives you a warm and fuzzy but folks need to understand that a truck like yours has precisely Zero additional coverage, or protection from Ford Corporate, when it comes to damage or perceived damage from mods.

You truck rolled out of the assembly plant outfitted just like any other Ranger within its trim level. Yours was not “ordered through Ford” it was ordered through some Ford dealer and up-fitted aftermarket. Not 1 ounce of difference, in relation to factory warranty coverage or lack of coverage, than an individual preforming the mods on their driveway or home shop.

I don't remember the specifics of it, but I do remeber a section in my warranty addressing the lift, and it being fully covered, with the standard eclusions, of course...off roading, racing, etc.

Love to see that in writing. 6” lift is a lot, hard on driveline.

Next time I'm at the bank, I'll try to remember to grab my docs from my safe deposit box. In the mean time, if you're interested in buying a lifted truck froma dealership, I would suggest checking with them. I would imagine when it comes to mods/custom orders, etc, every deal or dealership may vary in how they handle it.
