OEM flares are adequate for the stock 285's. I added the flaps for our travel trailer or any other tow behind.I have a reg f250 xlt with a pintop carli kit, i put method 18 x 9 with a +18 offset with 35" BFG's. Do you feel like you get enough coverage with the OE fender flares? My offset is +18 as well and was looking at adding flares on. I bought weather tech mud flaps but wasn't sure if the flares would cover my wheels. Trying to stay away from the pocket flares
One question would be how wide your 35" BFG's are?
Having replaced / repaired more than a few windshields, I wish more of these setups would look to adding flares.
