Wheel fit and clearing calipers

[Ja1034]

Hello - looking for some insight on wheel fit and clearing calipers on a 25 AT4.

Was about to purchase some 20x9 0 offset wheels and then as I was checking out, the site said I needed spacers to run them. I’m not opposed to spacers in general, but this is going to push the wheels out an extra 10mm (ish), which I really don’t want.

Reason given for this was to clear the calipers. Never ran into this with any vehicle before. Is this the style of the wheel causing this with the spokes? If so is there a measurement I can look at to avoid spacers?

Thanks in advance

I’ve been on several sites where they state that they recommend 3/8 spacers for most every wheel. It may be needed but I’m not so sure. Give them a call to confirm if it’s actually needed or just recommended.

Rim design and specifically how concave the spokes are can have an impact on if there will be interference with the caliper. Obviously the T1XX '21+ gen SUVs have the larger 4 piston front brake calipers, which has required many owners who are using rims meant for the GMT900 and K2XX SUV's to add spacers in order to clear the front brakes.

This is a good website to play around with on wheel and tire fitment. You can plug in your current wheel and tire specs on the left and then plug in the wheel and tire specs you're considering on the right and it will tell you how much closer things are to the suspension, how much farther the tires will poke out of the fender etc.

You might have to go out and measure how close the back of the spokes on your rim now is to your front brake caliper so you have an idea how much space you have to work with. Then based on rim offset get a feel for how much closer or farther away different rims are and go from there.

Thanks. Ordered a plus 18 with what I think is a spoke pattern that will work. Talked to a guy with a custom shop that said 0 will work all day with the right spoke pattern, so think I should be good.

Nice. Post some pictures when they’re on.

And of course they don’t fit… they are so close though. Think I’m going to stick with them and add some 3MM spacers to clear calipers.

That’s ok. Using 3/8 spacers is very common and even recommended by some shops that sell wheels.

ordered some cheaps from Amazon. Tested 3MM and 5mm. 5’s look better and provide full clearance. Will put me at +13 offset overall. Sent cheaps back and ordered some both hub and wheel centric customs.
