So i would like to put 35s on my 1993 f150. I have the 5.8L with a E40D trans and 4x4, Its stock and also has the factory forged aluminum wheels and wonder if those will still work.

 

Yes, but you will definitely need to lift your truck to make it work. What width are the tires you're planning on using?

 

i had planed a 4 inch lift with 35x12.50r15's on the stock wheels

 

Stock rims (7" wide?) are a little narrow for 12.50" tires. The rule of thumb is the rim should be about 2" narrower than the tire, so about 10" would be better. It's not that you can't use the stock rims, but you'll be more likely to rub the radius arm (you'll want some offset if you get wider rims, stock rims are at 0" offset). You'll also tend to wear the center of the thread faster than the edges, so it could hurt tire life. And it might give some quirky handling (although I think people have gone that big without commenting on problems).

Gearing might also be an issue. I had 33" tires on a '95 F-150 with a 351, E4OD and 3.55 gears. I liked the setup, but I did need to take it out of OD on winding or hilly 55 mph highways (it did fine on most freeways, whether at 55 mph or faster). 35s will be that much worse, unless you have 4.10 gears. If you're set on that size tire I'd encourage you to try them with whatever gearing you have. If you decide it's OK you'll have saved yourself a bunch of money. But do keep in mind that if you decide you do need to regear it can be about $1000 / axle (cheaper if you buy used axles that already have the right gearing).

 

thank you, okay i have also heard some say that the 4x4's can take 33x12.50's at stock ride height to with some trimming of the front bumper

 

Yes you can fit 33x12.50 on a stock height 4x4 I'm currently running that setup on my truck with the bumper trimmed. However I believe with stock wheels they may rub at full lock on the radius arms, but I'm not 100% on that cause I have aftermarket wheels.

 

how much do you have to trim?

 

Instead of trimming your bumper, consider installing 1-1/4" spacers at the bumper mounts. you will hardly notice the change unless you look for it.

I've got the 35 x 12.50 KOs on 10" rims on my 4 x4 truck with the 4" lift, but I don't remember the offset. check the couple of pixs in "my garage."

Yeah I'd give up on the 35's. For it to feel right/good/tight/everything amazing. You need lift and regear. Gets expensive too quick. On the 33's I have 32's with 3:55 gears and it still leaves something to be desired especially when comparing to my dad's old truck with 4:10 gears (he ordered the camper special with a C6...)

 

I ran 33s for a while at stock height and don't recall any rubbing aside from on the radius arms.

35s will fit with a 4" lift. I used a 6" lift and fit them just fine.


You definitely want to regear with that size of tire. I ran 35s for several years without regearing and my fuel mileage reminded me every day of it. I went with 4.56 and now have 36" tires.


4.10 would be a good choice if the truck spends more time in 2wd than in 4wd...
