Factory wheel 17x7.5 - Max tire width?

[Flip]

Factory wheel 17" x 7.5" Offset 6 3/4"

Do you know or can you help me figure out what is the widest size tire that will work with this factory wheel without wheel spacers and wont rub against the sway bar?

I currently have (255/80r17) 33x10" wide tires I bought and had installed by DT. From my measurements at full turn there is approximately 1 inch from the side wall of the tire to the sway bar in front. I have not measured the rear yet. I'm hoping a 11.2" - 11.5" (285/75r17) tire will work. By adding .75" on each side of the tire, in theory an 11.5" wide tire should work fine but the overall tire circumference is also larger by 1 inch so I'm quite 100%

Your thoughts?

A 285/75R17 only adds 0.6" to the sides of the tire and actually has a slightly smaller circumference than 255/80R17. You'll gain 0.2" between the top of the tire and the fender.
Sounds like it will work.

Thank you for your patronage, @Flip and for giving us the opportunity to help with the replacement tires!

From what we are seeing, 285/75R-17's will fit those wheels and should not have rubbing points under street driving (both front and rear). Your local store will do a test fit for good measure, however as mentioned, you should be in good shape with the 285/75's ?

255/80r17 is 33" tall - 285/75r17 is 34" tall. I think it will work and the Geolander tire total width is only 11.2" wide vs 11.5" wide. Should be fine.

Just remember this:

BIG Wheel require BIG Wheel

I put 35 x 12:50 GY Duratracs on my JLR, it's big and heavy. I went with aftermarket wheels with a 9 in width. The Duratrac is compatible with a 9 in. WHY?

The tire MFG will have a set of specs and for my tire its went to 9 in I got that to flatten out my tires contact patch. As a result I don't need to let as much air out of my tire, I run 34 psi vs the 37. Flatter contact patch + more rubber on the ground and less wear and better traction and stopping. And a WHOLE lot better traction in the off road world of rocks.

Few folks do it which is why they smoke their tires all the time on the trails and fall to back of the pack.
