Default Tire size help!

Hi all!
Looking to run 18x8.5 245/40 wheel setup in the front with a 18x9.5 255/40 4.5 bs wheel set up in the rear. Just wondering if I’ll have any rubbing issues/need to make any modifications for these to fit perfectly.

Thanks!

What's the front wheel bs? The rear should fit without any mods. I would go with a 275 on the rear with a wheel width of 9.5".

Front wheel is 4.5 bs and the rear is actually 5.25 mixed them up! And Didn’t think I could fit 275 in the rear without mods, but now I will deffinetly take a look into those now that I know that they fit!

I have the exact same wheel sizes front and rear with 245's on the front and 275's on the rear. I relocated my parking brake cable bracket to the top of the control arm. This may have not been necessary but I moved it anyway. My front wheels just barely clear the calipers but it does clear. The front tires touch the frame on full lock left and right but that will only happen when parking in a tight spot so not an issue for me anyway.

I've put 285/40/18's on 9.5" with 5.25" BS on the back of my 80 and on the back of my current 75 without any issues. You may need to move the parking brake bracket at worst.

Ok that’s really reassuring, just a quick question, when you relocate the parking brake bracket, do you route the cable on the inside (towards brake line) or outside of the trailing arm?
Thanks!

I have 18x9.5 with 4.75 BS all around. 275 40R 18 tires no mods to the factory setup.
