Wouldn't i put on 33 12.50r 16's and not 33 12.50r 15's on a
f -250.seems like the 15's are for a f 150 and the 33.12.50 r16's are for a 250 am i right here? or no?i dont wanna get the wrong tires.what does the 15 and 16 mean anyway?

 

The 16" is for the F-250 and the 15" is for the F-150.


Primary rig is Green Thunder:
95' F-150 XLT 4x4, 302, 5 spd, MSD 6A, Sunroof, CD player with 2 10" subs and some 32" BFG Muds .

Check out my Gallery for a look-see.


Then theres:
99' Mustang GT 4.6L
88' F-250 Superduty 4x4 351/c6
95' Mercury Cougar 4.6L V-8
80' E-350 300/6 with a
3 spd column shifter. Top speed is 65mph, Go Baby Go!

 

The 15, 16, 16.5 etc. is the rim size (the diameter of the rim). A specific rim is not for a specific truck. A 16" rim can go on a F150, F250, F350, Expedition, on probably any truck you want. I don't think that the 15" rim will work on the F150 or F250 because of caliper (brake) problems, atleast this is what I've been told from some 4x shops. Your F250 should have came with a 16" rim so I'd stick with a 16" or larger. Hope this helps a little.

 

The previous poster made a mistake in regards to an F-150. An F-150 comes stock with 15" rims, and will take anything larger, but nothing smaller. An F-250 can take anything larger that a 16" rim. I THINK that the 350s come with 16.5" rims and you could put anything larger than that. I should have clarified that in my first post, sorry. You can't go any smaller than what was stock because of the clearance on the brake caliper.

Ugh i'm sorry, an F-250 will take anything that is 16" or larger. An F-350 will take 16.5 or larger.

Just want to clear something up. 97 and newer f-150 4x4s come standerd with 17 inch rims, and 2 wheel drive comes with 16. I have a 4x4 and my dad has the 2 wheel drive.

 

And just to muddy the waters further, my best friend has 15's on his 2000 F-150 4x4

 

rockin ford, what year is your truck?

 

16.5's don't use bigger rims than 16's . . . they have a tapered bead that is a half inch bigger on the outside, but the rest of the rim is the same size as a 16. 16.5's came out before 16's and are not typically used on any vehicle made in the last 20 years or so, except for big tires. Also remember that before 1980, many F250's had 15" rims on them as they didn't have the big brakes yet. This is why there are 15" 8 bolt wheels available from the aftermarket. 1980+ F250's and F350's need 16 inch rims since the front rotor and caliper are so large, 15" rims will still fit on the rear axle of my '86 F250 with it's drum brakes.

 

No. I had plenty of 3/4 and up 70's truck, and all of them came stock with the 16.5 tires. They had the dual piston setup. You don't want to put 15 inch rims on a 3/4 ton. Ford didn't, either.

 

ok well my truck is a 95 f-250 4x4 its the heavy duty one the rims i got are 16.5x9.75. the tires i may put on them are 33 12.50r 16's will these rims fit my truck? i hope so i bought them used and wanna put them on.the thing i was wondering is what makes the 33 12.50r 16's and the 33.12.50r 15's different?one must be taller or wider.

 

You got a 16.5" rim and plan to put it on a 16" tire? Thats a no no, you can't do that. Your truck comes with 16" rims stock. So you can go either 16 or larger. The rims will fit on your truck if they have the right lug pattern but they are not going to fit on those tires. A 33/12.5/16 and 33/12.5/15 are the same in width and diameter. It's just the rim diameter inside the tire that is the difference.
