I am having MTF mini-tubs installed in my 65 FB and am starting the research for new wheels/tires. I will have the original rear in the car so will be trying to get the backspace correct that will give me the widest wheel/tire setup I can put in there without rubbing...including while doing hard cornering :). I know I want to go with at least 18's but also interested to see other combinations that might be larger than that.

I would think once you go past 18" the tire height will become a problem unless you like having no sidewall.

^ agreed. I put 17x8's on my '66 I just built, 245 tires. I ended up dropping to 7's in the front, and the 245's still rub bad. I'll probably end up replacing the tires with 235's or even 225's for clearance. I did the Shelby drop in the front, and have a narrowed explorer rear end in this one.

JMO, I'm thinking 17 max, and wouldn't consider 16, the 17 actually clears the uca and you can run wider than 16s. I just like the look of 15s

Mini tub. Narrowed leafs spaced to the inside of the leaf mounts. 18x9 5 5/8 backspace in rear with 295 rubber. Rear lip rolled. 18x7 in front



Princess kitty kins approves.



18s aren’t just for posers anymore. If you want wide sticky track tires and big brakes you’ll need to step up to the plate.

Walked into my garage as a kitten. My oldest was 4 at the time and had been begging for a cat. It’s been a pain in my ass ever since.

What backspacing? For future reference. Rear link?

It's been so long to remember exactly. From what I can recall is that the rear wheel was a 6.72" BS. I had the rear end built to accept the large BS - with each side .5" wider than stock.
The fronts were 18x9 originally as I liked the deep dish. I had them narrowed on the inside making them 18x7.5". The BS ended up being around 3.75"

The rear is a TCP 4 link but I had to re-engineer slighly to take advantage of the mini-tub. I moved the trailing arms inboard and the shocks outboard.

In my experience, 17's clear just fine. It's 16's that run into the UCA.
By clear I mean the wheel rim clearing, and running above the ball joint, "tucking" the ball joint inside the rim. There's no way a 17 does that. Though it may push the bulge of the tire up so the sidewall clears better. I suspect we're not both talking about the same thing.

We are defining "clear" in the same way. The wheel rim does in fact clear the ball joint. I'm sure some wheel designs differ, and may interfere, but most do not. I'm running 17's on the front and have zero UCA/rim clearance issues.
