Buying these Ford Performance Wheels for my Mach 1

[IanKar]

I checked the math and it took my a few minutes to get my head around this. But now I get it. Not sure if "true" square is essential where wheels/tires are perfectly straight with the front spacer (and the front can cope with being out by 22mm than normal?) or just use the same 10.5/305-30 all round with same 24mm offset but the rear are staggered. The goal for me is to have all the same wheels so that I only take 1 spare to the track and not two.

But I also note Tosha said about excessive poke. I have the 325 on the 11" on the rear and it works out okay but that's 5mm more than the designed 315 so 22mm may be too much.

Sorry, that doesn't make sense)))

It's a great idea in theory that won't work in practice.

You are mixing up offset with tire width

You’ll need a spacer with extended studs if the rear 11” goes on the front. Reread my response, I edited it with some links that will help.

This is correct information, as to poke who gives a flying. Just makes the car look more aggressive and planted.

Was going to do 11s for square but backed out because not a fan of the spacer, so we remain staggered.

Surely it plays a part in the poking out? So if I use a wider tire (same wheel) it pokes out 1/2 the difference of the width of tire? e.g. 325 wide tire sticks out 5mm more than the 315.

If you want properly rotatable setup for 305 tires, set of 11 wheels with 50-52 offset, 25mm spacers and extended studs on fronts is pretty much the only right answer. Tons of good lightweight options out there in the same price range - LMR, Steeda Trident, Apex and etc. Apex announced some great discounts for next week, I'm really tempted to get a set of 18 inch wheels from them for myself.

Correct on the 11” @ 52mm offset (305/30 tires) with 25mm spacer for front with extended studs. I have 2 sets of the HP wheels but those Apex wheels got me drooling.

Yes, NEVER a fan of spacers myself. This will probably get some negative response with the cars that run spacers but to each their own. Also to get hammered on the “it came staggered, it will stay staggered” thought process. I will be staggered as long as I own the Mach1.

I'm sure it's not the best idea to use it on road course . As long as I understand it correctly, he wants to have one spare for track use in case one of the weels gets shot. Technically you can do this with true square setup, but managing even wear on 5 wheels over time will be a real pita. Yes, one can say who gives a **** about it and still run it, but it will surely affect handling characteristics.

I'm sorry if my ESL is a barrier, but I think you need to read this: https://www.tirebuyer.com/education/what-is-wheel-offset#:~:text=Wheel offset refers to how,even body parts, like fenders.
Wider tires would surely have effect on overall dimensions but it's secondary compared to how offset affects everything.

@Mikepol2 put these on his car.

Not saying that the wheel is for tracking the car, only a means to get home. Misread your intent,

I think it's @IanKar 's intent actually I looked back at my reply post to him and I see how it may look confusing.

 

[shogun32]

if the intent is to limp home from the track where one wheel has been damaged and/or tire is shot (and the other 3 aren't?) then any size spare will do regardless of it's width as long as the rolling diameter is basically the same. So eg. a 265/35/19 on a 9.5" wide rim could work on an otherwise 305/30/19 shod car. Recommended? No, but doable.

If you're intending to go to the track and have a "matching" spare (might as well carry 2, you know) then standardizing on 19x11et50-52 with long studs and 25mm spacer on hand, is the only correct answer.

Pedant, perhaps but 305/30 tires on all 4 corners and wheels that are 10.5F and 11R isn't really "staggered".
