Is this too big?

Ok...

I've done lots of searching.

I've read lots of posts.

I've asked lots of questions.

I've had lots of great answers.

The problem with too much information is that it is difficult to distill it down to something clear and useful.

So...here goes the simplification:

I have a 2015 JGC Summit

I wanna go with the largest tires I can fit.

I believe what I've read says that 285 (aka 11.5") is the widest I can go with. Is that Correct?

I believe that I have also read that 32" is the tallest Outside Diameter that I can go with. Is that Correct?

So....regardless of all of the other distractor B.S.:
2015 JGC Summit V-8 with QL
No Wider than 285 (11.5")
No taller than 32"

Right?

Simple questions. Simple answers.

Any input on whether or not these points are factual or do I need to change my max width and height numbers?

Re: Is this too big?

285/50/20 is the widest you can go on stock wheels.
Some people have had success with a 275/55/20 which is a 31.8" tall tire.

Re: Is this too big?

Just remember that you need to account for your spare tire, too...it has to be the same diameter...and that your speedo and odo will not be accurate with the up-sized tires. There's no economic way to adjust the electronics for that, either.

Re: Is this too big?

Ok...now we are getting somewhere.

Based on these two responses, it appears that the WHEEL is limiting the width to 285. It also appears that the VEHICLE will accommodate a width of up to 305 (havent heard of that actually being done yet, but its food for thought).

And there is apparent confirmation that Im good for an outside diameter of less than 32"

So...to summarize:
Max width: 305mm (12")
Max Height: 32" Outside Diameter

All agree?

Keeping in mind that I have Quadralift, but dont plan on trying to do any harsh maneuvering while in "Park Mode".

Re: Is this too big?

Spacing will be very important if you go wider to avoid rubbing during tight turns "at the stops". You can't just choose a wheel and tire. There's more to it.

Re: Is this too big?

Understood.

However, all of the other threads on the topic start to wonder off into the weeds with debates over: Well what about this wheel or that wheel...what If I have a lift or spacers. Backspacing. QL Suspension. What if they are street/mud/rock tires....blah blah blah.

ALL of which are absolutely notable variables which make a definitive answer virtually impossible to achieve...and thus leading to hundreds of "related" threads (like this one).

Im simply trying to draw a big-box to play within. Establish parameters.

Based on the two responses...it appears that so long as I stay at or under 305 wide, and at or under 32" tall. I should be ok

Theoretically

2014 Summit - upsized to the 275/55-20 Michelin Premier LTX. Fits in all QL levels, no rubbing. Great Tire.

Re: Is this too big?

I have 33" tires on my WK2. BUT....

I had to put a front end leveling kit (1.75"). I had aftermarket 20" wheels, and just went back to 18" wheels and fit Toyo AT II extreme 285/65/18 tires.

That is the BIGGEST you can fit. They were barely rubbing the felt in the wheel well behind the tires but I zip tied that back and am clear now.

Hope this helps!! The leveling kit is worth it! I gained over 3" of lift total wit the tires and leveling kit.
