WOW!!! Finally somebody asked a question about tire fitment......

They'll fit fine as long as you only drive in a straight line. You WILL HAVE rub with the inboard front fender liner and "probably" in the rear of the fronts at the mud flap and/or liner. I just installed 285/75/18 on OEM wheels on my AT4 with the Rough Country 1318 - 2" leveling kit and they just clear at full lock and no articulation. I imagine if the suspension is heavily loaded while off-roading and near full lock I will rub the fender liner on the inboard side in the front. It's really close without any articulation. Tires I installed are the Toyo Open Country AT3 in 285/75/18 which are 34.8" x 11.3". If I do rub it will be minimal and I can get a little more room if I zip tie the liner back as many have done. Anything wider than 11.3" would cause me problems.

No. My truck would rub well before full lock if I ran a 0.4" wider tire even with a tire that is slightly "shorter. Might fit if I were to tie back the liner in the front and remove the mud flap mounting bracket. It would also get close to the UCA ball joint...

I recently installed 35's on my AT4 and found only two options for recalibrating the speedometer. Both Rough Country and Hypertech sell calibrators for $200 and $230 respectively. My speedometer is off about 4 mph at ~70 mph. I haven't bought either as I can live with it being off instead of spending over $200 just to get it correct. Additionally, there are numerous discussions on this forum and elsewhere online by numerous purchasers reporting functionality issues with both units.

Yeah, my philosophy with 4 wheel drive vehicles that are actually used off road is to fit the smallest "wheels" that will clear the calipers along with tires with the tallest sidewall. I personally don't understand putting large wheels with low profile "rubber band" tires on a 4 wheel drive vehicle. It defeats the purpose. Note I emphasized smallest "wheels" to make the point that they're not RIMS, they are wheels. One of my pet peeves is when folks call wheels "rims". A rim is just one component of a wheel. I know most find this to be petty but I just can't help myself. Calling a rim a wheel is like calling a cylinder head an engine...

Yeah, you're correct. I didn't think that through but different tire size won't change UCA angle. My comment was based upon just a visual observation. With the truck up higher I think it just gives an optical illusion of the angle being less severe. Changing the center line of the spindle/axle up or down doesn't change the control arm angles. Sort of funny as looking at it right now it still looks like a less severe UCA angle even though I know it's unchanged. Sorry, my bad for posting without thinking it through and just going upon what I thought my eyes were telling me. I've corrected my original post....

AT4 with Rough Country 2" Leveling Kit and 35" Toyo Tires I wanted to share the fitment of a Rough Country 2" AT4 specific leveling kit and 35" tires on 18" OEM wheels with the forum. After installing the AT4 specific RC leveling kit I was able to fit 285/75/18 Toyo Open Country A/T III tires without any rubbing. The tires are advertised as being 34.8" tall and 11.3" wide. I don't have any rubbing at full lock but it's pretty close. I think if I was at max articulation and full to nearly full lock in an off road setting I'd rub the fender liner a bit. Not enough to do anything about it but it would just rub. In over 1,000 miles of daily driving I've not rubbed a single time. Noteworthy comment/observations: 1. If I went with a 35" x 12.5" I would have significant rubbing with the fender liner. A true 12.5" wide 35" would not have adequate clearance. This is one of the reasons I went with the "narrow" 11.3" wide Toyo's. 2. Make sure you get an alignment after installing a leveling kit. My truck was significantly toed-out, outside the acceptable range with the leveling kit and resulted in a "darty" ride with a "floaty" feel. After getting an alignment and some toe-in the truck drives much better.

The OEM mats that came with my 2019 AT4 are FANTASTIC! Better than ANY aftermarket, vehicle specific mats I've bought in the past. I was very pleasantly surprised to see the General step up to the plate and put decent, high quality mats in the truck. Well done!!!

I just put Toyo Open Country AT3 285/75/18 (i.e., 34.8" x 11.3") on my 2019 AT4 with OEM 18" wheels and the Rough Country 2" leveling kit and they just barely fit with no rubbing on anything lock-to-lock. Offroading with articulation and I think I'll be rubbing the front of the front liner a tad but not bad enough to need trimming or wearing a hole through them. What I really like is how they decreased the angle of the UCA to what looks like a MUCH more acceptable angle. I realize you're asking about a 1.75" leveling kit but mine is close to what you're asking. I went with the Toyo 35" AT3's as they're only 11.3" wide. I think a 12.5" tire would have had issues with the UCA ball joint. I would have been close but the Toyo's offer plenty of ball joint clearance.

Rough Country and Hypertech are two companies I'm aware of selling plug and play correctors.

RadoPhan, as requested. Note my truck is an AT4 with the Rough Country 2" leveling kit. The other guy in the linked thread below is also running a leveling kit WITH the RL upper arms. It should be apples-to apples comparison between our trucks. FWIW, just physically eyeballing/looking at the OEM vs RL upper arms side -by-side show the OEM arms offer more clearance. FWIW, I read this same info on a number of different forums.

No issue with handicapped folks, I just don't understand handicapped steps being installed on trucks that take away from the ground clearance and get ripped off the first time you get hung up on even a medium sized rock. Hell they did away with "running boards" on cars back in the 30's or 40's. I guess they're fine for trucks who serve only as mall crawlers...

Note, the Ready Lift upper control arms provide LESS clearance than the OEM upper arms. There's a couple posts on here depicting the loss of clearance with pictures and measurements.

Put it in neutral and set the Parking Brake. Truck will run until the tank is empty.
