Ford Ranger Wheel Calculator v1.5

1. If there are certain tires you would like me to add, reply with your request.
2. If you an error, or know real word specs differ from listed specs send a DM
3. Some tires listed have been announced, but not yet released.

INSTRUCTIONS:

1. Click on the link below to open google sheets
2. Go to FIle > Make a copy. Now you can edit and sort.
3. Modify red cells to calculate combined weights or custom tire dimensions
4. Filter & sort tires by clicking on the header arrows in row 10

SOME COLUMNS ARE COLOR CODED BASED ON WEIGHT

"Greener" means a lighter setup
"Redder" means a heavier setup

v1.3 CALCULATOR ADDITIONS

• Rotational Mass
• HP Loss\Gain
• Wheel package weight

Users can now calculate the best combined wheel package weight for rims 15"-26" with all matching tires.

Lighter tires = better mileage & performance, but you should also consider:

• Durability
• On\Off road traction
• Snow\Ice\Wet grip (tread + compound + siping)
• Width & Clearance
• Ride & Noise quality
• Rim Compatibility
• Load\Speed rating
• Looks
• Price

v1.4 RIM SELECTOR ADDITIONS

You can now choose rims from a drop down for various sizes and the sheet will auto magically calculate the wheel package weight for any tire that will fit on the rim!!! If you want to use a custom weight, simply change the custom weight field in the Rim Calc

Need help with Rim Sizes and Weights !!!!

Reply with your favourite rim in the following format:

(Brand) (model) (Diameter)x(Width) (offset) (Weight)

For Example:

Enkei RPT1 17x9 +0	24
Ford OEM Ranger Lariat 17x8 +55	32
Ford OEM Ranger Raptor 17x8.5 +55	28.3
Ford OEM Ranger Raptor BL 17x8.5 +55	36.4
Ford OEM Ranger XL 17x7.5 +55	25
Ford OEM Ranger XLT 17x7.5 +55	31
RTR EVO 6 17x9 +0	24.4
RTR EVO 6 17x9 +30	22.6
Vision Warrior 17x8.5 +25	22.35
Vossen HF6-4 17x8.5 +35	26
Vossen HFX-1 17x8.5 +35	26

Tire Code Cheat Sheet

When tire shopping these codes help you figure out what the hell you are buying

Here's the coding breakdown for a suitable 6G Ranger 35 inch tire:

P 315/70R17 128/125S F RWL

P - Tire Class

• P: Passenger Car
• LT: Light Truck
• C: Commercial trucks
• ST: Special Trailer
• M/C: Motorcycle
• T: Temporary (spare tire)
• XL, HL, or Reinforced: Tires with a higher load capacity than normal for their dimensions
• KO: 'Key Benefit: On and Off-road' - Versatility in both on-road and off-road conditions
• KM: 'Key Benefit: Mud' - Enhanced traction and durability in muddy environments
• KX: ‘Key Benefit: Extreme' - Enhanced performance in extreme wet and dry conditions
• KT: ‘Key Benefit Toughness’ - Enhanced traction and durability

315 - Section Width (tread width)

• Nominal width of tire in MM

70 - Aspect Ratio

• Ratio of the sidewall height as a percentage of the section width of the tire.
• To calculate Total Tire diameter:
  • calculate twice the sidewall height (2 * width * aspect ratio)
  • convert to inches, then add rim diameter
  • In our example: (2 * 315 * 0.7 * 0.0393701) + 17 = 34.36 inches

R - Construction

• R - Radial
• B - Bias Belt
• D - Diagonal
• Omitted - cross ply tire

17 - Rim Diameter

• Rim size the tire was designed for (inches)

128/125 - Load Index and Range

• 128/125 = 3968/3638 lbs
• The 2nd lesser number is the load rating for a dually configuration (in case of a blowout)
• Load index rating can be looked up at tirepressure.org

Do you know what light size KO3s are coming out? I was about to pull trigger on C 265/70/17

This is awesome, it will definitely help me when I'm ready to run larger than the 255/70/17

49?! Amazing. Where did you learn this rumour?

 

[Hande]

Great list! Thank you for making it! Looks like Territory MT 315/70-17 is the choice for me, being closer to M/T tire than KO2 or KO3 but still lightweight.

 

[Steeliegreen]

I like it!

 

[iBrad81]

I think other options to add would be Mickey Thompson, Nitto, Toyo and Falken.

 

[YukonRanger]

49?! Amazing. Where did you learn this rumour?

I stumbled across it while I was getting info from the database, I noticed that the site had a bunch of tires listed without actual links to buy them, or bring up detailed info. Several of them were for tires that are coming out next year.

So I assumed the C class KO3 315\70R17 page could have been one of those tires and it was listed at 49 pounds, which is absurdly light for a tire that size.

My guess is it will be around 55, but we’ll see.

 

[jacksdad]

Best weight I’ve seen for a tire that I’m interested in is the Toyo AT 35x12.5x17 at 59#

 

[BigMeatsBronco]

Nice work, can you add a column on spreadsheet to search for " rim diameter " ...? thanks
