Sorry they are 295/70/18

Those look awesome!!! Those are what I want, but I'm concerned about the weight. Any seat of the pants difference with acceleration or braking?

I'm on the fence between these and the Cooper AT3 XLT in the same size. The Cooper is less aggressive in appearance, but are 8 pounds lighter.

Anyone put 295/70/18 on a AT4 yet? I'm wondering if they'll fit as have heard the wheel well opening is smaller.....

Honest I wouldn't worry too much about the weight. I'm running MT Baja MTZs that weight 69 lbs each along with rims that weigh 38 lbs each and my truck still launches with no issue. I have not really noticed any loss of acceleration quickness

I had seen his truck on fb and also want this tire size on my AT4...i would like the mastercraft m/t as they are 62lbs and 34.25x12.

There is another AT4 here that was running 35x12.5 tires with no leveling kit. Let me see if I can find it.

Would love to see The AT4 running the 35's and his set up

Okay so here it is.@destrada127 hope you dont mind. So here are the pics from that thread. He was running 35x12.50r20 Accelera MT-01 which according to tire-easy.com they measure out 34.5” tall the width I couldn’t find, on carid.com it also states they are 71lbs. He mentions he trimmed the mudflaps but that it was unnecessary. I believe later on he added a 1.5" leveling kit. On the pic the tire seems to be less than 34.5" but perhaps he can chime in and give us the actual number.

The red AT4 is my buddy’s with a 5.3 and running 33x12.50r18 he also has no rubbing and those are 12.7” wide however they are much only 33” tall according to tiresize.com the reason i included them is because they are 72.6lbs and his truck came with them from dealer. Buddys at4 mpgs are around 12.5-13 so the weight did hinder his numbers as my stock AT4 5.3 with duratracs 49lbs tires are netting me 15.3-16.2 and we do similar commutes as we leave nearby each other and work together.

Link of the thread I took info from. Just in case I forgot something.

My favorite pic

This was after he added the 1.5" motofab leveling kit

Everything written above is accurate. The tires off the rim, unmounted, measured out to 34.5" but after mounting and on the vehicle they measure out to 34" exactly and only 9.5" wide (footprint). The trimming was unnecessary while running the stock wheels, however, I have since upgraded to new wheels 20x9 -12 offset which did require quite a bit of trimming. I was planning on running 37x12.50 with only the 4" rough country lift, but this would only be possible on the factory wheels or +32 offset

Thanks for jumping in @destrada127

I guess those 295x70r18 (34.3x12) on our AT4's might be too tight. I wanted to order the tires online as the deals our cheaper however I feel that I may need to test fit them instead at a tire shop prior to purchasing.

Your AT4 looks amazing by the way. The leveling kit and front bumper has definitely added to its monstrosity . Love where you added the AT4 emblem on the front.

Arnold and Dustin,

Thanks so much for posting so much explanation and pics. I suspect the measurement of that tire only being 34 inches is because it was measured vertically, with the bottom part of the tire being mashed under the weight of the truck. A more accurate measurement would have been horizontally and would likely be the true measurement. As you said, it measured 34.5 prior to installation.

Though there wasn't much room to spare, you definitely proved that a 35x12.5 tire could fit, depending on the brand. So, I'm comfortable knowing it can be done.

My truck isn't here yet, so still have some time to ponder.

It can be done as long as you're on a stock rim if you do aftermarket rims it becomes much more difficult.
