A flat Good Year Wrangler SR-A set the tire shopping in motion, and a 10% off sale on Nittos convinced me to try the 35x11.50r20 Ridge Grapplers. 

 

My goal was to get as much tire as possible without having to adjust the suspension so as to retain the stock ride, keep costs down, and achieve the aesthetic I like for modern 4x4 trucks. I was prepared to crank the front keys a few turns for up to 1" of leveling, but my preference was to avoid this if possible.

 

Ridge grapplers have two sidewall designs on the tire; one side reminded me of Transformers, so I went with the more subdued sidewall. This doesn't impact fitment.

 

After about 20 miles of driving and some parking lot testing turning the steering back and forth, the tires fit fine with only a few close spots throughout the range of motion. I've seen people report frame rub at full lock with these sizes; it hasn't happened to my truck yet, but I wouldn't be surprised if it rubs mildly while turning sharply over rough terrain. 

 

Rear clearance is fine. 

 

A few tips:

  • Check the actual dimensions of the tire you're choosing. The Nittos are 35s, but the actual diameter is about 34.7". Each manufacturer is a little different, and most list the true dimensions on their websites. The same applies to metric sizes - a BFG may be narrower than a Toyo.
  • Looking at my truck, 35x12.50r20 would have fit too, but would probably rub on the wheel wells while going over bumps during a turn. The 11.50s provide just enough extra room that my truck has yet to rub, though my mileage count is low (20 miles since install) so I'll update this thread as I add miles.
  • Expect to lose fuel economy. No data yet, but I anticipate a 1-2 MPG drop. 
  • Aftermarket wheels change everything. The popular offset or "poking" look makes it harder to stuff big tires without a lift. If you're changing wheels and tires, disregard this thread.

 

What's next?

 

Fresh oil, a detail, and maybe a front window tint. I'd like a Corsa, but they're $$$. 

 

Please excuse the dirty truck:

Nice truck, like the green, looks great.

Nice tires, running them myself,  285 75 18, I really like how quite they are, as quite as the Michelins that they replaced.

Those are Ridge Grapplers not Trail Grapplers, big difference in road noise over the Trail Grapplers.

You're right, I fixed my typos!

Nice. Made appt. for new shoes today - going with Cooper AT3 XLT (LT275-70R18). I "guess" $1000 isn't horrible installed :)

Please post some pictures of your 285/60/20 Cooper AT3 XLT tires, I would like to see that size mounted up.

    • I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.    
    • Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.
    • If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.
    • It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.
    • JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
