Did you order this set and install it?

 

[The Widge]

Did you order this set and install it?

no, my wife's AT4 is in transit next week and trying to figure out what rims to get. I'm leaning on getting black Denali rims and slapping grapplers on, I like the look of Dave Sinclair's builds blacked out. hers will be white and I'm blacking out top half and badging. still looking for more options tho

Was able to fit 275/65 on my 2025 with no lift. No rubbing at all. The tires come out to be like 34.1" x 11".
These are the Toyo R/T Trails.

@getRADIOACTIVE do you have air ride and/or mag ride? If not, does anyone know if those options would prevent running this same size (275/65/20)?

Oversize tires are likely going to affect vehicle performance. Oversize tires are usually much heavier than the tires than come stock, the extra weight and height of the tire will affect performance. The taller the tire, the higher the gear ratio will become. Larger tires will also have a larger rotating mass due to the increase in weight. Both of these issues will result in a loss of low-end torque and possibly fuel mileage. Your engine will have to strain harder to get the wheels rolling at the start and use more fuel. The smaller the engine, the more it will affect performance and put a strain on all components not to mention up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, which will cause it to travel more distance per revolution than the original equipment tire.

Why did you feel the need to post any of this in this thread?

Here’s my 21 z71, no air ride or level/lift. No rubbing.

Thank you for this!

305/35R/24's fit just fine on my 2025 AT4 with no scrub, had to add a 12mm spacer due to the brake calipers on the front which still had plenty of stud for a snug fit.

Anyone put 305/55R20 on a 2022 Yukon XL Denali with Magride?

I'd really like to get some Fuel Rebars with a +20 offset vs the OEM +28 and some 275/65-R20 and have zero rub and require zero modifications.

These look good. No issues with the 275/65-20 I see, but you also have the OEM wheels, correct?

My guess is that they will rub. I say this because my 07 has 305/50x20 tires, and the tire is very close to, but not quite touching the fender liner.

I think tire fitment is the same across all trim levels and Chev vs GMC. Ride height is at least the same across standard suspension options (maybe not PPV). 305/55R20 is shorter but wider than stock AT4/Z71 tires and much shorter that my 315/70R17.

I have several posts on fitting the 315/70R17 winters at stock height which required the Westcott fender liner kit (I DIY'd an equivalent). 305/55R20 might or might not require the liner mod but it's not a big deal. On OE wheels (26 to 28ET), be careful of sidewall to ball joint clearance.

My original tires (summer) are almost finished and I'm planning 315/70R17 or 35x12.5x17 on 0ET which will require further trimming or a minor lift (1" - 2").

Anyone put 285/60/22 on a Tahoe that has 275/50/22?

My Tahoe High Country has 22” chrome wheels which I originally thought were way too blingy and I thought the 22” wheels would ride harsh but I was surprised. They are actually really smooth even over rough roads. Maybe the higher side wall 60 vs the standard 50 would be even better or am I missing something?

Either way I think I need to change out the wheels. They are very nice but a little too much chrome for me.

So was able to get 285/50/22 Toyo AT3s on my 23 High Country. Can’t remember if I test fitted a 60, but I can’t imagine they would fit.

No issues, sometimes at full lock on an uneven parking lot it will graze the fender liner but nothing that’s of concern.

Yes, I have LT275/65/20 (34” tire) on OEM wheels.
