I can't answer your question definitively, but here are pictures of those rims on my car with smaller tires. I'm lowering it this winter, but haven't installed the suspension yet.

Those tire sizes you list will be very close to the fenders. Go to your local tire place and tell him you'll buy the largest tire that will clear, and maybe he'll mount them for free to find out?

Beautiful Rims the rubber fit really well and nice!!! Thank you for sharing............Are those BBS FI in Gloss Black??? I had order mine but I only got an option for Matt Black and BBS won't do a Gloss Black for me. Done some research BBS Matt Black is actually Satin Black in my opinion.

Anyway will respray the rim to Gloss Black when arrive. Thank you again for sharing.

Cheers.

That's some huge rear tires.

Fronts should be fine, but rears should be no larger than 305 for a 10.5 inch wheel.

315/35/20 is a bad setup for rear.
First of all the maximum size for 10.5" rim is 305.
Second with this setup the total diameter of rear wheel is 28.7" compare to 27" for standard one. basically you are increasing the size of wheel for about 6%. This setup may change many things including the ride, handling and traction...

Thank you for the reminder, just check on my tire again it should be 30 not 35. Noted will stick to a 305 max. Thank you.
