does anybody know a good place to get used offset rims for 35 inch tires or so that have the same centercaps as the f150s. i found a real nice pair with tires for 325. i like the way they look with the caps and everything but im not sure ill beable to get them. i wont need spacers either. how do you change for the milage and everything. will it give better mpg too if i got 3.55 ratio limited slip 4spd with a 300.

 

i picked these up a couple weeks ago.

theyre procomp wheels and i just drilled and tapped the rim to use the factory center caps

 

Those are awsome but the look expensive. I seen some with 35s and rims like the 92-96 f150s

 

its these ones here. i just painted the outer fake "beadlock" trim silver
i got them for $180 for the set used
152 Rock Crawler Series - Gloss Black Street Lock Wheels by Pro Comp

 

that looks good!! I wanted to keep my factory aluminum rims with my 35's, but the tire man said it wouldn't do right, cuz they were 7.5" wide. So I got the next best thing, which probably look better anyway with the truck. Lol

 

I ran 35's on my factory rims. They did rub a little but they worked...

 

Mine are 33" 12.5.
I has 32 11.5 on the factory aluminum rims before these ones and they rubbed

 

Mine don't rub, but the tire shop said that the tire wouldn't handle like it was suppose to, on the 7.5" wide rim, that I needed a 8.5" or preferably 10" wide if I was doing off-roading and running low psi in the tires.

 

This is why I like living in a more rural area. The guys at the tire shop here will do whatever you want to have done without hesitation.

Had them mount my 33x12.5x15's I picked up a few weeks ago on my factory 15x7.5" rims, they didn't advise me to go with wider rims, etc.

 

The reason to go with a wide rim in a wide tire is that with low psi on a wide tire and a narrow rim is that the rim mushes around side to side in the wide tire and this can cause issues. With a wide rim this doesn't happen so much.
I would use 10" wide rims on a 12.5" wide tire. As for backspacing, anything with 4" or lower shouldn't rub at full lock.
As for the gearing, what do you have for gears now? if you have 35" tires I would put 4.11 gears in the truck honestly. It will be a lot easier for the truck to get rolling that way. If you're going to pay for different gears you might as well get ones that are worthwhile.
I don't know what year truck you have, but if you have a 4 speed manual it should be an 87 or so. anyway, in 4th gear in a 1:1 ratio, you should be pulling about 2000-2200 rpms @ 60 mph just to give you an idea what it is with 4.11 gears.

 

He told me he'd do whatever I wanted, that he was just giving me some advice.

 

87 f150 with 355 gears limited slip. 300 i6. would i get better mpg or worse.

 

I would re-gear. Yellow is hwy, black is close to factory, blue is for performance.



Note: This chart is based on engine rpm at 65 mph with the transmission in a 1:1 gear ratio (Third with a three-speed manual, Fourth with a four-speed manual, or Third with an Automatic). Remember, the actual rpm indicated in the chart will be slightly higher (between 100 and 300 rpm) on vehicles equipped with an automatic transmission. This is due to the slip present in an auto transmission's torque converter.

 

Oh ok, yeah it probably is more logical to go with something wider like 15x10's but since I got my 33's for $140 I'm just sticking with stock wheels for now.

You would get worse, I would imagine you are getting upwards of 20 MPG with the straight 6 now so might drop a couple MPG's.

Shouldn't be as bad as my 5.0 V8 though, I was getting about 11 MPG with stock 235/75/15 tires and am now getting about 9 MPG with 33x12.5x15's.

 

wow never would even think it would get around 20mpg. i was thinking about 13 or so. havnt licesned truck yet so i have no idea. so around 20 i dont think it will bother nme too much if i getting around the smae mpg with bigger tires than what i thought was what it would originally get with stock wheels. i will probly never put different ratio. i will be just fine with it. how do you copensate for for milage too. will the spedometer read the same if igot bigger tires or will it have to be changed some how.
