Wheel Size Dilemma

They rubbed the leaf springs. I had pictures of them rubbing the rust off over time where the tire made contact. I didn't buy the wrong wheels, but thanks for telling me how my own truck drove.

I just don't understand how they rubbed the leafs? I mean I am not saying you are wrong but logically isn't the point of a negative offset to move the tires away from the leafs and other suspension parts?

A taller tire will be closer to the leafs at full lock.

Well, a 12.5 35 and a 12.5 37. Should be the same. Right? Now going with a wider tire, would defiantly run more.

The majority of the rubbing was on the bumper and fender liner. At full lock the tire would barely make contact with the spring. They were toyo M/Ts. Regardless unless you trim with 4 inches or lift it to 5-6 inches it's going to rub like hell.

Ugh. So disappointing lol. 12 wides look so awesome. I don't want to do a bunch of trimming though.

I'm not telling anyone how their truck should or did drive. I'm just saying with the right wheels, a 12.5" wide tire should not rub the springs. My 39.5" tires did rub the leaf springs with the same 12" wide wheels, but the tires were 18" wide, IIRC.

My 35" by 12.5" Super Swamper SSR's did not rub the leaf springs anywhere, and they were pretty aggressive tires.

That is a 3.5 inch hanger lift on stock V-code springs, BTW. 5" rear block. Had to trim the front bumper, and pull back the liners, but did not rub the springs at full lock.

I don't necessarily agree with this. I see what you are saying, but don't believe that a taller tire is more likely to rub the leaves, unless your front end is all wore out and sloppy.

That thing looks good man! The tires stick out perfectly. I'm also a sucker for black haha.

Get some wheels then. I wouldn't be afraid of 12" wide wheels. If for some reason they rub the leaf springs, then you could always run spacers. You could always adjust your suspension some to get a little extra height if needed. You could run your 4" lift, then add a mini spring pack to get an extra inch or more if you needed it. I think a true 4.5 to 5" of lift would be perfect for 35" tires on 12" wide wheels.

You sir, are correct. I'm gonna get 12s. If a problem does arise. I will fix it when it comes.

This is a 2" mini spring pack, I believe you can remove leaves to reduce lift. It is probably a 1/4" per spring.

Between this and/or spacers, you will have your bases covered.

Right but without an adjustable track bar....
