I apologize for the same old question... but can I run 35/12.50 on an 18 inch rim with just a leveling kit installed? I am willing to cut the plastic/front splash gaurd if necessary.

Welcome to FTE!

 

Absolutley.

I have a 04 F250 with 315's with a leveling kit.
All I had to do was cut 1" off of the lower air valance on each side you cant even tell I cut it. Took about 2 minues with a saw zaw.
I am guessing your rims have a 4.5 in backspacing right???
That is a must, or you tires will hit the leaf springs.

 

I currently have my stock rims, but plan on buying new ones. If you would, can you set me straight on the combination of the 35's with the correct rim size so I dont screw up?

Thanks

 

Your rims need to be either 9 in wide or 10 in wide with 4.5 on backspacing.

As far as height of rim that is up to you.
I am running 16X10's bceause I like a little more sidewall to my tires.

Just remember if you increase to a 17 or 18 in rim you add about $25 per tire per inch you go up. 35X18' are a lot more expensive than 35X16"

Also make sure you are getting the 8X170 Bolt pattern. That is what our truck run.

 

Any pictures of your tires/wheels on your truck?

 

Keep in mind that different brands/model tires of the same rated size are not actually the same size. Some are bigger than rated, some are smaller.

My BFG TA K/O's in 315/75-16 did not require any trimming with only 2" lift as they are slightly under a true 35".

 

MWS make a good point, also even in the 250 class different trucks have lighter or heavier springs in front, which may make a little differrence. Also each lelveling kit raises the front just a little different.

Any way you look at it you can do what you want with little to no modifications.

 

Thanks again. I believe I have found what I want but there may be a slight issue.
Tires: Pro Comp 35 12.50 R17
Rims: Xtreem Allows Series 7005. They are 17x9, 8 on 170 but 4.75 on backspacing

Will this .2 in variance in the backspacing kill the deal?

Thanks again mwsf220 and ffadragon for your help.

 

With the 35 inch tall tire and only a leveling kit, you will most likely get some rubbing on the plastic inner fender liner, and maybe on flex/turns, the front lower bumper. With the 4.75 backspacing, you will most likely rub the leafs on full lock turning. Both can be overcome with a few minor alterations to the truck. Good luck!

 

on my truck they rub at full lock but do not hit the plastic part of the bumper.

what minor alteration can i do to stop the tires from rubbing?

 

To stop them from rubbing the leaf springs, I welded a small nut to the bump stops at the steering knuckles.

 

9" wide rim you'll want 4.5" backspacing, 10" you'll want 5" backspacing. You could go up to 1/2" more backspacing than that, but you'll be close to the leaf springs then. I have 35x12.50x18s on Diamo 17 Karats which are 10" wide with 5.06" backspacing, the tread is about 1/4" outside the fender and 3/4" from the springs at full lock. The further in you tuck them, the less fender and bumper clearance issues you'll have.

That backspacing on a 9" wheel should be about ideal.

 

ok so i have another question i was going to adjust the bump stops but i realized that this would hurt my turning when i put my stock size tires on that i use when ever i have to tow long distances. what would you think about putting on 1/4 in wheel spacers?

 

You can drill and tap your bump stops and screw a bolt in to make them adjustable.
