I don’t find it any worse than stock.
I’m sure it is - based on physics and math, but it’s nothing that’s obviously noticeable.
Do you have the Max Tow ? Whats your mpg?

The 285/75/17 tires should work fine, but you're going to have to remove the air dam or whatever that hunk of junk is that bridges the bumper and the fender. There are some threads on how to trim it so that you get rid of it, but keep the fog lamps covered. Then again, I've seen Youtube guys who just took them off and didn't have anything covering the fogs from behind and they have had no issues at all with it.

285/70/17’s on my stock non max tow Sport S, no rubbing whatsoever. EDIT: I’ve since removed my closure panels between the bumper & fender strictly for looks

Can you please tell me the height measurement of the tires after mounted? I was told that the milestar 37’s measure out at 35 inches. Trying to confirm before purchasing.

Since the topic of tire has come up. I recently joined this forum after ordering a Mojave. I am planning on a leveling kit and changing to 18” rims that have a 4.5 backspace with a 275/70r18. Will the tires stick out past the fender?

It kinda depends on rim width. Can't remember having checked, but with oe wheel, I set tire size to 35.5 for speedo correction. When I get home in a few hrs, I'll double check. Supposed to measure at 36.5-36.7 on 9.5 or 10 in width wheel. Highly recommend 3.5" lift minimum for any 37 tho on lower clearance fenders. 2.5" on rubi fenders.

Lord Enzo,
So thankful to receive a reply. The rim width is 9” with a -12 offset. I’m worried that the tires will stick out too much beyond the fender. I think with 18” rims with a 70r is a little over 33”. So I’m not worried about rubbing. This Mojave is mainly going to be a beach, fishing running around vehicle. Not much crawling,

Here’s mine as promised (but earlier than I thought). Discount Tire got my order in quicker than planned and had an open spot for me today.

I LOVE how the truck sits now on these 33s (Falken Wildpeak AT3W, C rated, 116Q). Even though they’re inflated to 40 psi cold pressure right now, these tires were still nice on the highway at 70-75 mph. I was pleasantly surprised at how quiet they were too….just as quiet as the stock tire actually. Still plenty of power, even though these things weigh almost 64lbs. I could feel the slight difference in oomph though.

This picture isn’t EXACTLY from behind the truck, but the tire is perfectly flush with the fender flares on the wide axles and stock Sport S wheel. I’ll grab more pics tomorrow in the daylight if anyone needs them.

I can’t wait to hit the Hill Country, Texas trails with these new shoes this fall!
