Cooper Discover AT3 295/60/20s on the stock Platinum wheels?
I've exhausted my search on this so I'm posting the question here. The truck is a 2010 CrewMax Platinum(5.7 4wd). I just installed OME-614s (shocks front and rear) and COACHBUILDER +3 shackles, also differential drop. The lift got me 3.5-inches up front and 1.5 in the rear. No other modifications at this point. Upper control arms are stock and will remain stock for the foreseeable future since my alignment was within specs that are acceptable to me.
So the question is: Am I going to be able to fit Cooper Discover AT3 295/60/20s on the stock Platinum wheels (+60 offset), WITHOUT hitting/rubbing the UCAs? For some reason I thought the offset on these wheels was +50 and that I would have no problem with this size, but after a little more searching I learned they are actually +60. Cooper lists the actual dimensions for these tires as 34.13" x 11.5". A quick measurement of the stock tires (275/55/20), then extended out to 11.5" using tire centerline, puts the new tires ON the UCA.
Problem is: I realized this the day after ordering the 295/60s, so the tires are on the way. Yeah, I know I should have done more research and figured this out before ordering, but I thought it was figured out. I am aware of wheel spacers and adapters, but really didn't want to have to do anything like that. I would have rather went down a size if I had thought I'd need spacers or adapters to make it work. I was told that it still might work, but with only 3/8" clearance and that 1/2" was the preferred minimum.
Is anyone running this tire on these wheels (or stock 20" limited wheels)? If so, did you need spacers? Also, I was thinking that trimming wouldn't be necessary, am I wrong on this?
Thanks for any help.
